GLOSSARY OF TRAINING AND NUTRITION TERMS
L-carnitine -- Neither an amino acid nor a vitamin, L-carnitine is
a derivative of hydroxybutyric acid. It is naturally obtained from red
meat, and helps release stored bodyfat (triglycerides) into the
bloodstream for use in cellular energy processing. Its physiological role
is to transport long-chain fatty acids into the mitochondria for energy
production. This is believed to improve one’s fat metabolism (lower body
fat level) as well as long-term energy level. Research has also shown
L-carnitine to have a value in treating certain cardiovascular disorders,
including hardening of the arteries.
Lactate -- Lactic acid.
Lactic acid -- A byproduct of glucose and glycogen metabolism in
anaerobic muscle energetics. A minute accumulation causes muscular fatigue
and pain, and retards contraction.
Lactic acid is carried by the blood to the liver, where it is
reconverted to glucose and returned as blood glucose to the muscles. It is
this elevation of blood lactic acid in sustained strenuous exercise, such
as in marathon running, which results in muscle fatigue and pain. Recovery
follows when enough oxygen gets to the muscle, part of the lactic acid
being oxidized and most of it then being built up once more into glycogen.
The metabolic cooperation between contracting skeletal muscle and the
liver to support active muscle work is called the Cori cycle.
Lactose -- Lactose is a disaccharide of milk which on hydrolysis
yields glucose and galactose. Bacteria can convert it into lactic acid and
butyric acid, as in the souring of milk. It is used in infant feeding
formulas, in other foods and as an osmotic laxative and diuretic. Lactose
is not tolerated in many persons after weaning, owing to a reduced lactase
activity.
Lats -- Short for latissimus dorsi, the large muscles of the back
that are the prime movers for adduction, extension and hyperextension of
the shoulder joints.
Lean body mass -- All of you, except your fat. Includes bone,
brain, organs, skin, nails, muscle, all bodily tissues. Approximately
50-60% of lean body mass is water.
Lean body weight -- The weight of the body, less the weight of its
fat.
Lever -- A rigid object (bone), hinged at one point (joint) to
which forces (via muscle contraction or resistance) are applied at two
other points. A lever transmits and modifies force or motion, and has
three parts: 1) a fulcrum, 2) a force arm and 3) a resistance arm. There
are three classes of levers, depending on the location of the three parts
relative to each other.
Ligament -- The fibrous, connective tissue that connects bone to
bone, or bone to cartilage, to hold together and support joints. Cf.
tendon.
Limit Strength -- Absolute strength enhanced by hypnosis,
electrotherapy, ergogenic substances of any form (including nutritional
supplements or drugs) or other techniques. Such aids increase the
potential for strength above normal capacity. Absolute strength is reached
solely through training.
Lipid -- A number of body substances that are fat or
fat-like.
Lipoprotein -- Combination of a lipid and protein. Cholesterol is
transported in the blood plasma by lipoproteins. Cf. high-density
lipoprotein, low-density lipoprotein.
Longitudinal study -- A study which observes the same subjects over
a period of time. Cf.
cross-sectional study.
Lordosis -- The forward curving of the spine at the neck (cervical
spine) and lower back (lumbar spine). Often used to refer to an abnormally
increased curvature of the lumbar spine.
Low blood sugar -- See hypoglycemia.
Low-density lipoprotein (LDL) -- A lipoprotein carrying a high
level of cholesterol, moderate levels of protein and low levels of
triglycerides. Associated with the building of othersclerotic deposits in
the arteries. Cf. lipoprotein, high-density lipoprotein.
Lower abs -- Slang for abdominal muscles below the navel.
Conventional training wisdom holds that one can "isolate" the lower from
the upper abs through leg raises or reverse crunchers. In reality, when
the abdominals contract, the contractile forcee is generated throuhout the
entire abdominal wall.
Lumbar -- Pertaining to the lower back, defined by the five lumbar
vertibrae, just above the sacrum.
Magnesium -- A pivotal mineral important to protein synthesis,
energy production, muscle contractions and a strong heart muscle.
Essential for metabolism of calcium, phosphorus, sodium, potassium and
vitamin C. Chronic muscle cramps is a typical sign of a shortage. RDA: 350
mg. (men), 300 mg. (women). Dietary sources: figs, lemons, grapefruit,
yellow corn, almonds, nuts, seeds, dark green vegetables.
Maintenance load -- The intensity, duration and frequency of
exercise required to maintain an
individual's present level of fitness.
Manganese -- A key enzyme activator. Also vital to the formation of
thyroid and reproductive hormones, normal skeletal development, muscle
reflexes, and the proper digestion and utilization of food. No RDA.
Dietary sources: whole grains, egg yolks, nuts, seeds and green
vegetables.
Maria Thistle -- The active compound in Maria Thistle is
silymarin. It is known to be 1) a potent hepatoprotector and
antihepatotoxic agent (thereby restoring normal metabolic function to the
liver), 2) promotes cellular regeneration via increased protein synthesis,
3) aids in protecting the kidneys, and 4) acts as a powerful antioxidant
principally through its sparing effects on glutathione (which also
probably accounts for its potency in improving liver function).
Max -- Maximum effort for one repetition of a weight training
exercise. Also expressed as one's "1-RM" or "one rep max." Max o(V,.)O2
See maximal oxygen uptake.
Maximal heart rate -- The highest heart rate of which an individual
is capable. A broad rule of
thumb for estimating maximal heart rate is 220 (beats per minute) minus
the person's age (in years). Cf. graded exercise test.
Maximal oxygen uptake -- The highest rate of oxygen consumption of
which a person is capable.
Usually expressed in milliliters of oxygen per kilogram of body weight
per minute. Also called maximal aerobic power, maximal oxygen consumption,
maximal oxygen intake. Cf. o(V,.)O2 max.
Maximal tests -- An exercise test to exhaustion or to levels of
oxygen uptake or heart rate that cannot increase further with additional
work loads. Cf. graded exercise test.
Medical history -- A list of a person's previous illnesses, present
conditions, symptoms, medications and health risk factors. Used to
prescribe appropriate exercise programs. Persons whose responses indicate
they may be in a high-risk category should be referred for medical
evaluation before
beginning an exercise program.
Medical referral -- Recommending that a person see a qualified
medical professional to review
their health status and determine whether medical treatment is needed
or whether a particular course of exercise and/or diet change is
safe.
Mesomorph -- A person whose physique features powerful
musculature.
Met -- A measure of energy output equal to the resting metabolic
rate of a resting subject. Assumed to be equal to an oxygen uptake of 3.5
milliliters per kilogram of body weight per minute, or a caloric
expenditure of 50 Kcalories per square meter of body surface per hour.
Hard exercise, for example, requires up to eight METs of energy
expenditure, which equals eight times the resting energy
requirement.
Metabolism -- The total of all the chemical and physical processes
by which the body builds and maintains itself (anabolism) and by which it
breaks down its substances for the production of energy
(catabolism).
Metabolite -- Metabolite is any substance which forms as a
by-product of the catabolism, growth, or anabolism of living
tissue.
Military press -- Pressing a barbell from upper chest upward in
standing or sitting position.
Minerals -- There are 96 times more minerals in the body than
vitamins. As vitamins, they are necessary for life itself and combine with
other basic components of food to form enzymes. Minerals are ingested
through food and water. Many minerals are deficient in the diet because of
mineral-poor agricultural soil, the result of intensive farming and
long-term use of chemical fertilizers and pesticides.
Minimum daily requirement (MDR) -- The minimum amounts of protein,
vitamins and minerals considered necessary to maintain health. Cf.
recommended daily allowance, optimal daily allowance.
Mitochondria -- Mitochondria are the rod-shape organelles found in
the cytoplasm of cells. They are the source of energy in the cell and are
involved in protein synthesis and lipid metabolism.
Moment arm -- The perpendicular distance from the line of pull of a
muscle to the axis of rotation.
Moment Of Force -- See Torque.
Monounsaturated fat -- Dietary fat whose molecules have one double
bond open to receive more
hydrogen. Found in many nuts, olive oil, and avocados. Cf.
polyunsaturated fat, saturated fat, unsaturated fat.
Motor neuron -- A nerve cell which conducts impulses from the
central nervous system to a
group of muscle fibers to produce movement.
Motor unit -- The basic unit of movement: a motor nerve fiber and
all of the muscle fibers it supplies. In the quadriceps muscle, one neuron
can activate as many as 1,000 fibers. In the eye, where great precision is
required, one nerve cell may control only 3 fibers.
Motor unit recruitment -- One of the factors affecting strength.
Refers to your ability to get maximum stimulation through the nervous
system to trigger the maximum amount of contractile force through maximum
motor unit recruitment. This can be built up over time through heavy
resistance and explosive strength training.
Muscle -- Tissue consisting of fibers organized into bands or
bundles that contract to perform bodily movement.
Muscle fiber -- Synonymous with muscle cell. See fiber.
Muscle group -- Specific muscles that act together at the same
joint to produce a movement.
Muscle fiber arrangement -- Long fibers are created for large
movements and speed rather than strength. Short fibers are designed for
strength with a lesser movement capability. Knowledge of fiber arrangement
can help you train muscle groups in a scientific manner.
Muscle pull (strain) -- Major or minor damage to muscles from
excessive stretching or use. The key to avoiding muscle pulls is proper
conditioning and strict adherence to a thorough program of warm-up and
cool-down.
Muscle spasm -- Sudden, involuntary contraction of muscle or muscle
group.
Muscle spindle -- The "computer" of muscle tissue, a modified fiber
which responds reflexively to mental impulses and muscle movement such as
stretching. Measures and delivers the quantity of muscle force needed to
perform a given action. Rapid stretching of the muscle, for example,
results in messages being sent to the nervous system to contract the
muscle, thereby limiting the stretch. Cf. Golgi tendon organ,
proprioceptor.
Muscle tone -- , "Muscle tone" or "tonus" refers to the degree of
resting "tension" in a muscle. Weight training results in a greater number
of muscle fiber "firing" while at rest. It's Mother nature's way of
keeping your muscles in a "ready" state to contract more forcefully and
instantaneously if needed. The partial contraction results in your muscles
feeling "tight" or "hard" to the touch.
Musculotendinous -- Pertaining to or composed of muscle and
tendon.
Myocardial infarction -- A common form of heart attack, in which
the blockage of a coronary artery causes the death of a part of the heart
muscle. Cf. infarction.
Myofibril -- The functional units within muscle fibers that cause
contractions. The more you have, the greater your strength.
Myofibrillarization -- increasing myofibrils -- is achieved with the use
of heavy weight training.
Myofilaments -- The elements of a muscle cell which comprise
myofibrils that actually shorten (thereby providing contractile force) by
sliding across one another via action of "cross bridges." They are
comprised of the proteins actin and myosin.
Myoglobin -- An iron-containing protein responsible for oxygen
transport and storage in muscle tissue, similar to hemoglobin in
blood.
Myoneural Junction -- The connection of a neuron to a muscle
fiber.
Myosin -- The most abundant protein (68%) in muscle fiber. It is
the main constituent of the thick contractile filaments which overlap with
the thin actin filaments in the biochemical sequence that produces
contractions.
Myositis -- Inflammation of a skeletal muscle.
Myositis ossificans -- The deposit of bony materials in the muscle.
Bruises from contact sports
may result in this condition. Severe bruises should be iced, and
evaluated by a physician.
Nautilus -- Variable resistance-type exercise machine which
attempts to match the amount of resistance with the user's force output.
Arthur Jones, developer of Nautilus equipment in the 1970s is considered
one of the true pioneers of fitness technology. He coined the term
"Nautilus" because of the sea shell appearance of his earlier machines'
cams. However, the concept of varying resistance by using offset cams was
invented and in use during the 1800s in Europe. Jones' marketing strategy
involved his widely adopted "one set to failure" principle. He disavowed
it in the mid 80s, however (right after selling his business), and his
legion of disciples (i.e., owners or sellers of his equipment) all but
vanished.
Negative reps -- An eccentric contraction. One or two partners
assist in lifting a weight up to 20 - 40% heavier than an individual could
normally lift. Once hoisted to the extended position, the weight is slowly
lowered without help. This type of exercise is extremely damaging to
connective tissue, and (according to the "cataclysmic" theory of
overtraining) is the elemental factor in overtraining and cumulative
microtrauma.
Neuromuscular re-education (NMR) -- Therapy involving deep rolfing
massage and neurological stimulation to eliminate painful strength- and
movement-limiting adhesions and scar tissue in muscles caused by trauma.
Developed by Drs. Gary Glum and Joseph Horrigan, Los Angeles chiropractors
specializing in soft-tissue injuries in sports.
Neurotransmitter -- A biochemical that spans the gaps between nerve
cells, transmitting an electrical impulse.
Nicotine -- Nicotine is an alkaloid found in the tobacco plant.
Nicotine first stimulates the central nervous system, then depresses it.
It is absorbed easily through the mucous membranes and the skin, and is
highly toxic; symptoms include nausea, vomiting, twitching, and
convulsions. Nicotine is used as an agricultural insecticide.
Nitrogen balance -- An estimate of the difference between nitrogen
intake and output in the body to measure protein sufficiency. Derived by
subtracting amount of urea nitrogen in a urine sample from an individual's
total protein intake. If urea value is larger than protein intake, the
nitrogen balance is negative, indicating that not enough protein was eaten
to meet the body's nutritional needs. In this situation, muscle protein is
sacrificed to provide additional protein to fund metabolic processes.
Prolonged negative balance results in muscle wasting. Positive nitrogen
balance is achieved by ingesting complete protein to meet the body's
metabolic needs.
Non-resistance training -- Training without weights in which you
pit muscle strength against body weight to develop general and aerobic
fitness. Includes mild running, calisthenics, jumping, skipping, swimming,
and bicycling.
Nordihydroguaiaretic Acid -- NDGA (nor-di-hydro-guai-aretic acid)
is the primary active constituent of the chaparral bush, which grows in
southwestern USA (to over 1000 years old!). It is widely known in the
scientific community as a powerful antioxidant, and has the official
designation as a "lipoxygenase inhibitor." Both research and folklore
classify NDGA as effective in 1) cellular respiration, 2) analgesic
activity, 3) anti-inflammatory activity, and 4) vasodepressant activity.
These functions make NDGA a potent anti-ageing substance.
Nutriceutical -- Actually nothing more than a cross between the two
words, "nutritional" and "pharmaceutical," a nutriceutical is any
nutritional supplement designed for any specific clinical purpose(s).
Thus, engineered foods such as Ensure, Enfamil, Nutriment, Met-Rx
and IGF-33 are regarded as nutriceuticals. Due to FDA and FTC
regulations, clinical or medical claims cannot be made for them. Thus, all
are functionally (legally) on the market as foods for general consumption
(or "health foods") to be used as "supplements" to nutrition (diet).
Medical doctors frequently utilize these and other nutritional supplements
in myriad clinical settings. See supplements, and see nutrition.
Nutrients -- Food and its specific elements and compounds that can
be used by the body to build and maintain itself and to produce energy.
Conventionally, this word refers to the macronutrients (water,
protein, fats, carbohydrates) and the micronutrients (vitamins, minerals
and trace elements) that are essential for energy and growth. On a legal
(FDA) level, it specifically excludes substances for which claims are made
(legitemately or illegitemately) for amelioration, cure or prevention of
any disease entity or other clinical functions beyond growth and
energy.
Nutrition -- The programmatic use of nutrients
Obesity -- Excessive accumulation of body fat.
Obliques -- Short for external and/or internal obliques, the
muscles to either side of abdominals that rotate and flex the
trunk.
Octacosanol -- The active, energy-boosting component of wheat germ
oil which is known to improve endurance, reaction time, and muscle
glycogen storage. Taken as a supplement.
Olympic lifts -- The two weightlifting movements used in Olympic
competitions: the snatch, and the clean and jerk. The military press was
eliminated as a contested lift after the 1972 Olympics. See
weightlifting.
Olympic set -- High-quality, precision-made set of weights used for
competition. The bar is approximately 7' long. All moving parts have
either brass bushings or bearings. Plates are machined for accurate
weight.
One repetition maximum, 1 RM -- The maximum resistance with which a
person can execute one repetition of an exercise movement. Cf.
repetition.
ODA -- Optimal Daily Allowances. ODAs are applied to active people
such as athletes and fitness enthusiasts whose nutritional requirement are
beyond those of the normal (sedentary) people upon whom the FDA’s old RDA
scale was devises.
Origin -- The attachment of a muscle to the less moveable or
proximal (closer to the center of the body) structure.
Ornithine -- Ornithine is produced in the urea cycle by splitting
off the urea from arginine and is itself converted into citrulline. On
decomposition it gives rise to putrescine. It has been demonstrated to be
of value as a growth hormone stimulator when administered intravenously;
there is no solid evidence that it stimulates growth hormone to a
significant degree (enough to stimulate muscle growth) when taken
orally.
Ornithine Alphaketoglutarate (OKG) -- OKG has been clinically shown
to:
1) decrease muscle protein catabolism
2) improve nitrogen retention in muscle tissue
3) augment muscle tissue polyamine (PA) response
4) mediates an insulin increase
5) improves both protein synthesis and wound healing in muscles
6) promote anabolic (muscle building) processes
Clinically, it is successfully used in treating burn patients as well
as traumatized, surgical and malnourished individuals. There's no doubt
about its tissue-building properties in clinical use. While no studies
have been reported on its use as a supplement for athletes, it's clearly
logical to infer that OKG will aid them in gaining muscle mass and to
greatly improve post-workout adaptation and recovery processes.
Osmolarity -- The concentration of a solution participating in
osmosis. (E.g., a sugar-water solution of high osmolarity is concentrated
enough to draw water through the membranes of the digestive tract to
dilute the sugar.) Cf. hypertonic, hypotonic.
Osmosis -- The movement of fluid through a membrane, tending to
equalize the concentrations of the solutions on both sides. Cf.
osmolarity.
Ossification -- The formation of bone. The turning of cartilage
into bone (as in the joints). Cf. myositis ossificans,
osteoarthritis.
Osteoarthritis -- A noninflammatory joint disease of older persons.
The cartilage in the joint wears down, and there is bone growth at the
edges of the joints. Results in pain and stiffness, especially after
prolonged exercise. Cf. arthritis.
Overload -- Subjecting a part of the body to efforts greater than
it is accustomed to, in order to elicit a training response. Increases may
be in intensity or duration.
Overload principle -- Applying a greater load than normal to a
muscle to increase its capability.
Overtraining -- Excessive training, principally of the eccentric
contraction phase of lifting weights or running. Can cause injuries, loss
of body weight, insomnia, anorexia, depression, chronic muscle soreness
and retard workout recovery.
Overuse -- Excessive repeated exertion or shock which results in
injuries such as stress fractures of bones or inflammation of muscles and
tendons.
Overuse Syndrome -- Injury resulting from overtraining.
Oxidation -- Oxidation is the chemical act of combining with oxygen
or of removing hydrogen.
Oxidative Sports -- Sports such as long distance running or cycling
wherein oxygen must be present to allow movement to continue (see ATP/CP
Sports and Glycolytic Sports).
Oxygen (O2) -- The essential element in the respiration process to
sustain life. The colorless, odorless gas makes up about 20 percent of the
air, by weight at sea level.
Oxygen consumption -- See oxygen uptake.
Oxygen debt -- The oxygen consumed in recovery from exercise above
the amount that would normally be consumed at rest. In intense endurance
activities, oxygen debt refers to the amount of oxygen that is "owed" to
the system to oxidize lactic acid build-up. One's tolerance for an
accumulated debt is generally proportional to the level of fitness.
Oxygen deficit -- The energy supplied anaerobically while oxygen
uptake has not yet reached the steady state which matches energy output.
Becomes oxygen debt at end of exercise.
Oxygen Uptake -- The amount of oxygen intake used up at the
cellular level during exercise. Can be measured by determining the amount
of oxygen exhaled as compared to the amount inhaled, or estimated by
indirect means.
Parcourse training -- A concept borrowed from outdoor parks and
applied to the gym during sports-specific phase of foundation training for
aerobic athletes. Involves the performance of aerobic activities --
jogging, skipping rope, straddle jumping, bicycle ergometer -- between
exercises of a weight training routine.
Partial reps -- Performing an exercise without going through a
complete range of motion. Exercise mythology has it that one must exercise
a muscle through a full range of motion of the joint upon which the muscle
acts in order not to become "muscle bound" and to derive maximum strength
and growth. In reality, partial movements often provide better overload
because more weight can be moved.
Peak contraction -- Exercising a muscle until it cramps by using
shortened movements.
Peak heart rate -- The highest heart rate reached during a work
session.
Pecs -- Slang for pectoral muscles of the chest.
Peptide -- A peptide is any member of a class of compounds of low
molecular weight which yield two or more amino acids on hydrolysis. Formed
by loss of water from the NH2 and COOH groups of adjacent amino acids,
they are known as di-, tri-, tetra- (etc.) peptides, depending on the
number of amino acids in the molecule. Peptides ("polypeptides")form the
constituent parts of proteins.
Peridoxine Alphaketoglutarate (PAK) -- Vitamin B6 (peridoxine) is
ionically combined with the complexing agent, alphaketoglutarate to form a
high energy compound. It is widely used as a nutritional supplement by
athletes wishing to improve energy output.
Periodization -- "Periodized training" is a phrase which refers to
how one’s training is broken down into discreet time periods called
"macrocycles, mesocycles and microcycles.
Peripheral heart action (PHA) -- Deveeloped in the early 60s by
Chuck Coker (inventor of the "Universal" multi-station exercise machines),
PHA training is an excellent all-around system of weight training whereby
muscles are exercised in an alternating sequence of upper and lower body.
This method keeps blood circulating constantly throughout the body,
prevents undue fatigue in any given muscle, facilitates recovery and
provides a holistic muscular development. It is mildly cardiovascular.
pH -- A measure of acidity, relating to the hydrogen ion (H+)
concentration. A pH of 7.0 is neutral; acidity increases with lower
numbers, and alkalinity increases with higher numbers. Body fluids have a
pH of about 7.3.
Phosphorus -- Works with calcium to build up bones and teeth.
Provides a key element in the production of ATP. RDA: 800 mg. Dietary
sources: animal protein, whole grains.
Physical conditioning -- A program of regular, sustained exercise
to increase or maintain levels of strength, flexibility, aerobic capacity,
and body composition consistent with health, fitness or (especially)
athletic objectives.
Physical fitness -- The physiological contribution to wellness
through exercise and nutrition behaviors that maintain high aerobic
capacity, balanced body composition, and adequate strength and flexibility
to minimize risk of chronic health problems and to enhance the enjoyment
of life.
Physical work capacity (PWC) -- An exercise test that measures the
amount of work done at a given, submaximal heart rate. The work is
measured in oxygen uptake, kilopond meters per minute, or other units, and
can be used to estimate maximal heart rate and oxygen uptake. Less
accurate, but safer and less expensive than the graded exercise
test.
Physiology -- The study of the body's functions.
Plasticity -- The term plasticity refers to the profound ability of
muscle, in this case skeletal muscle, to adapt to different perturbations
or stimuli. These adaptations can be measured at the molecular, cellular,
tissue, and whole muscle level. Skeletal muscle, more so than any other
tissue (except maybe the uterus during pregnancy) , exhibits a tremendous
ability to remodel itself.
Plyometric -- A type of exercise that suddenly preloads and forces
the stretching of a muscle an instant prior to its concentric action. An
example is jumping down from a bench and immediately springing back
up.
PNF stretch -- See proprioceptive neuromuscular facilitation
stretch.
Polyunsaturated fat -- Dietary fat whose molecules have more than
one double bond open to receive more hydrogen. Found in safflower oil,
corn oil, soybeans, sesame seeds, sunflower seeds. Cf. monounsaturated
fat, saturated fat, unsaturated fat.
Post-exercise muscle soreness -- Microtrauma to connective tissue
releases an amino acid called hydroxyproline which, within 48 hours,
causes irritation to local nerve endings, triggering pain. Typically
occurs from exertion or concentrated movement after a long period of
disuse but even affects the most physically fit athletes after excessively
stressful exercise.
Potassium -- Teams with sodium to regulate body's water balance and
heart rhythms. Nerve and muscle function are disturbed when the two
minerals are not balanced. Insufficient potassium can lead to fatigue,
cramping and muscle damage. Physical and mental stress, excessive
sweating, alcohol, coffee, and a high intake of salt (sodium) and sugar
deplete potassium. No RDA. Dietary sources: citrus, cantaloupe, green
leafy vegetables, bananas.
Power -- Work performed per unit of time. Measured by the formula:
work equals force times distance divided by time. A combination of
strength and speed. Cf. strength.
Powerlifts -- Three lifts contested in the sport of powerlifting:
the squat, bench press and deadlift. Powerlifting was first organized in
the USA in the early 60s from the "odd lifts" competitions which used to
be part of almost all bodybuilding and weightlifting competitions. Of the
over 40 odd lifts contested, these three lifts were chosen as being the
most representative test of total body limit strength.
Power training -- System of weight training using low repetitions
and explosive movements with heavy weights.
Preload -- The stretching of a muscle prior to contracting it,
thereby providing both a "stretch reflex" and a viscoelastic component,
adding to the total force output.
Primary risk factor -- A risk factor that is strong enough to
operate independently, without the
presence of other risk factors. Cf. risk factor, secondary risk
factor.
Prime mover -- The muscle or muscle group that is causing the
movement around a joint. Cf. agonist.
Progressive resistance exercise -- Exercise in which the amount of
resistance is increased to further stress the muscle after it has become
accustomed to handling a lesser resistance.
Pronation -- Assuming a face-down position. Of the hand, turning
the palm backward or downward. Of the foot, lowering the inner (medial)
side of the foot so as to flatten the arch. The opposite of
supination.
Proprioceptive neuromuscular facilitation (PNF) stretch -- Muscle
stretches that use the proprioceptors (muscle spindles) to send inhibiting
(relaxing) messages to the muscle that is to be stretched. Example: The
contraction of an agonist muscle sends inhibiting signals that relax the
antagonist muscle so that it is easier to stretch. (Term was once applied
to a very specific therapeutic technique, but now is being widely applied
to stretch techniques such as slow-reversal-hold, contract-relax, and
hold-relax.)
Proprioceptor -- Self-sensors (nerve terminals) that give messages
to the nervous system about movements and position of the body.
Proprioceptors include muscle spindles and Golgi tendon organs.
Protease -- Proteases are a category of enzymes which attack
specific bonds between amino acids and proteins. The proteases break amino
acid bonds to split up the protein molecule into smaller pieces of lined
amino acids.
Examples of proteases are renin and pepsin; these enzymes can be found
in animals. Rennin is used in the thickening of milk and is isolated from
the stomach of the calf; pepsin is found in the gastric juices of humans
and other animals where it breaks down proteins at specific places.
Protein -- One of the three basic foodstuffs -- along with
carbohydrates and fat. Proteins are complex substances present in all
living organisms. It comprises 90 percent of the dry weight of blood, 80
percent of muscles, and 70 percent of the skin. Protein provides the
connective and structural building blocks of tissue and primary
constituents of enzymes, hormones and antibodies. The components of
protein are amino acids. Dietary protein is derived from both animal and
plant foods.
Protein is essential for growth, the building of new tissue, and the
repair of injured or broken-down tissue. They serve as enzymes, structural
elements, hormones, immunoglobulins, etc. and are involved in oxygen
transport and other activities throughout the body, and in photosynthesis.
Protein can be oxidized in the body, liberating heat and energy at the
rate of four calories per gram. Cf. amino acids, essential amino
acids.
Protein efficiency ratio (PER) -- A system of rating the quality of
dietary protein by the number and proportions of the essential amino acids
contained in it. Eggs rank highest. They contain all eight essential amino
acids in a proportion regarded as the most readily assimilable and usable
combination of naturally-occurring amino acids. Eggs are the standard by
which all other protein sources are rated for assimilability.
Proprioceptor -- Sensory organs found in muscles, tendons, joints
and skin which sense and provide information about movement, body position
and environment.
Pulmonary -- Pertaining to the lungs.
Pulmonary (ventilatory) capacity -- The efficiency of gas exchange
in the lungs.
Pumped -- Slang term to describe the tightness in a muscle made
large through exercise. The pumped sensation results from blood
engorgement and lactic acid accumulation in the exercised muscle.
Pumping iron -- Slang for lifting weights, a phrase used since the
1950s.
Pyramid Training -- A training protocol incorporating an upward-
then-downward progression in weight, rep-per-rep or set-per-set.
Pyruvic Acid -- Pyruvic acid is the end product of the glycolytic
pathway. This three-carbon metabolite is an important junction point for
two reasons: it is the gateway to the final common energy-producing
pathway, the Krebs cycle; and it provides acetyle coenzyme A (acetyl CoA),
through which fatty acids, and in turn fat, are produced from glucose.
Pyruvic acid converts to lactic acid as needed. Pyruvic acid increases in
quantity in the blood and tissues in thiamine (vitamin B-1) deficiency.
Thiamine is essential for its oxidation.
Qing Obesity Treatments -- The ancient Chinese have been observing
and recording the symptoms of obesity for thousands of years. They
observed three distinct varieties (below). These observations and
recommended treatments were recently put to a test at Xi Yuan Hospital in
China. Xi Yuan Hospital is the headquarters of the China Academy of
Traditional Chinese Medicine. Based on the clinical manifestations
recorded by the Ancients, the researchers at Xi Yuan Hospital were able to
treat obesity --on a permanent basis -- in 80 percent of the cases.
Type I Symptoms (spleen-wetness and phlegm-stagnation): Stuffiness in
the chest, shortness of breath, general fatigue, muscular weakness,
dizziness, heart palpitations, abdominal distention, poor appetite,
whitish coated tongue, weak pulse. Treatment: Qing Xiao.
Type II Symptoms (excessive heat in spleen and stomach): Gluttonous
eating habits, frequent hunger, flushed face, dry mouth, reddish tongue
with yellowish coat, constipation, forceful pulse. Treatment: Qing
Tong.
Type III Symptoms (Qi-stagnation and blood stasis): Chest pain, feeling
of distention, irritability, good appetite, irregular menstruation or
amenorrhea, slightly dry stool, purplish dark tongue with pronbounced
spots, regular pulse. Treatment: Qing Jiang.
Quads -- Short for quadriceps, the four thigh muscles that extend
the knee (all but the Vastus Intermedius also flex the hip). They are:
1. Rectus Femoris (Dominant front thigh muscle)
2. Vastus Intermedius (Underlies the Rectus Femoris)
3. Vastus Lateralis (Bottom of thigh, outside above knee)
4. Vastus Medialis (Bottom of thigh, inside above knee)
Quadriceps -- A muscle group at the front of the thigh connected to
a common tendon that surrounds the knee cap and attaches to the tibia
(lower leg bone). The individual muscles are the rectus femoris, vastus
intermedius, vastus lateralis, and vastus medialis. Acts to extend the
lower leg.
Quality training -- Training prior to bodybuilding competition
where intervals between sets are reduced to enhance muscle mass and
density, and low-calorie diet is followed to reduce bodyfat.
Radial pulse -- The pulse at the wrist.
Ratio of fast, intermediate and slow twitch fibers -- A fundamental
strength factor relating to the distribution and specific capabilities of
fibers within muscle tissue. "Fast twitch" (predominantly white fiber)
muscles are stronger and more suited for strength activities. "Slow
twitch" (red fiber) muscles are more enduring and suited for long-distance
exercise. This ratio can be only slightly changed through training. You
must train fast to be fast, and train long to be enduring.
Rating of perceived exertion -- A means to quantify the subjective
feeling of the intensity of an
exercise. Borg scales, charts which describe a range of intensity from
resting to maximal energy outputs, are used as a visual aid to exercisers
in keeping their efforts in the effective training zone.
RDA (Recommended Daily Dietary Allowances) -- Estimates established
by the National Research Council of the National Academy of Sciences for
nutritional needs necessary for prevention of nutrient depletion in
healthy people. Does not take into account altered requirements due to
sickness, injury, physical or mental stress, use of medications or drugs,
nor compensate for the nutrient losses that occur during processing and
preparation of food. RDA standards do not apply to athletes, who have
extraordinary nutrient needs. While they were designed to meet the needs
of a majority of people, RDAs are nonetheless far too low for serious
athletes and even for fitness enthusiasts who exercise regularly. (See ODA
-- Optimal Daily Allowances)
Reciprocal Innervation -- A phenomenon in which the opposing muscle
group is stimulated to relax while the prime mover muscle(s) is
simultaneously stimulated to contract, thereby allowing movement to
occur.
Recruitment -- Activation of motor units; the greater the
resistance encountered, the greater will be the Rectus recruitment
necessary to overcome its inertia.
Rectus femoris -- The long, straight muscle in the front of the
thigh which attaches to the knee cap. Part of the quadriceps muscle
group.
Recuperation -- A physiological process involving full body and
muscle recovery and subsequent muscle growth during a rest period between
training sessions. Optimum increases in muscle growth or strength occurs
only with complete recovery.
When you increase the intensity of your workout, there's a price that
must be paid. That price is DISCIPLINE in finding ways of improving your
recuperative ability. The most important method is called "periodization"
training. There are ancillary methods:
working
closely with a sportsmedicine and or a sports sciences expert.
Remember:
1. Big muscles take longer to recover than smaller ones
2. Fast twitch muscles (your "explosive" muscles) take longer to
recover than slow twitch muscle fibers ("endurance" muscles);
3. Guys recover faster than girls;
4. You recover faster from slow movements than from fast movements;
5. You recover faster from low intensity training than from high
intensity training.
Rehabilitation -- A program to restore physical and psychological
independence to persons disabled by illness or injury in the shortest
period of time.
Renal -- Pertaining to the kidney.
Repetition -- An individual completed exercise movement.
Repetitions are usually done in multiples. Cf. one repetition maximum,
set.
Rep out -- Repeat the same exercise movement until you are unable
to continue.
Residual volume -- The volume of air remaining in the lungs after a
maximum expiration. Must
be calculated in the formula for determining body composition through
underwater weighing.
Resistance -- The amount of weight used in each set of an exercise,
or the force which a muscle is required to work against.
Respiration -- Exchange of oxygen and carbon dioxide between the
atmosphere and the cells of the body. Includes ventilation (breathing),
exchange of gasses to and from the blood in the lungs, transportation of
the gasses in the blood, the taking in and utilizing of oxygen, and the
elimination of waste products by the cells. Cf. expiration, inspiration,
ventilation.
Response -- An immediate, short-term change in physiological
functions (such as heart-rate or respiration) brought on by exercise. Cf.
adaptation.
Rest interval -- Pause between sets of an exercise which allows
muscles to recover partially before beginning next set.
Rest pause training -- Training method where you press out one
difficult repetition, replace bar in stand, then perform another rep after
a 10-20 second rest, etc.
Retest -- A repetition of a given test after passage of time,
usually to assess the progress made in an exercise program.
Risk factor -- A behavior, characteristic, symptom or sign that is
associated with an increased risk of developing a health problem. Example:
Smoking is a risk factor for lung cancer and coronary heart disease. Cf.
primary risk
factor, secondary risk factor.
Ripped -- Slang meaning extremely visible muscularity resulting
from both hypertrophy and subcutaneous fat removal.
RM -- Acronym for "repetitions maximum." Thus, for example, 5RM
stands for the maximum amount of weight you can perform for five
repetitions.
'Roids -- Slang for anabolic steroid.
Rotator cuff -- A band of 4 muscles that hold the arm in the
shoulder joint.
Sartorius -- The longest muscle in the body, involved in the
movement of the thigh at the hip joint.
Saturated fat -- Dietary fat from primarily animal sources.
Excessive consumption is the major dietary contributor to total blood
cholesterol levels and is linked to increased risk for coronary heart
disease.
Saturated Fatty Acid -- A saturated fatty acid is an acid which, by
definition, has no available bonds in its hydrocarbon chain; all bonds are
filled or saturated with hydrogen atoms. Thus the chain of a saturated
fatty acid contains no double bond. The saturated fatty acids are more
slowly metabolized by the body than are the unsaturated fatty acids.
Saturated fatty acids include acetic acid, myristic acid, palmitic
acid, and steric acid. These acids come primarily from animal sources,
with the exception of coconut oil, and are usually solid at room
temperature. In the case of vegetable shortening and margarine, oil
products have undergone a process called "hydrogenation", in which the
unsaturated oils are converted to a more solid form. Other principal
sources of saturated fats are milk products and eggs.
Sedentary -- Sitting a lot; not involved in any physical activity
that might produce significant fitness benefits.
Selenium -- A major nutrient antioxidant along with vitamins A, C
and E. No RDA. Dietary sources: wheat germ, bran, tuna.
Screening -- Comparing individuals to set criteria for inclusion in
a fitness program, or for referral to medical evaluation.
Secondary risk factor -- A risk factor that acts when certain other
risk factors are present. Cf.
primary risk factor, risk factor.
Set -- A group of repetitions of an exercise movement done
consecutively, without rest, until a given number, or momentary
exhaustion, is reached. Cf. repetition.
Shin splints -- Pain in the front of the lower leg from
inflammation of muscle and tendon tissue caused by overuse. Cf.
overuse.
Siberian ginseng (eleutherococcus senticosus) -- A cousin of
traditional Oriental ginsengs widely used among Russian athletes for
boosting stamina and endurance, speeding workout recovery, and as a health
tonic to normalize systemic functions and counter stress. An adaptogenic
substance that enables athletes over time to adapt to increased training
intensity.
Simple carbohydrates -- Simple carbohydrates are monosaccharides
and disaccharides occurring naturally in fruits, vegetables, and dairy
products. Some examples of simple carbohydrates are glucose, galactose,
and fructose, all of which are monosaccharides and, sucrose, lactose, and
maltose, all of which are disaccharides.
Most simple carbohydrates elevate blood sugar levels rapidly, providing
"instant energy" which is quickly utilized and dissipated. Fructose is an
exception. Additionally, refined sources of simple carbohydrates, such as
candy, contribute only calories to the diet. These "empty calories" are
often consumed in place of foods which would provide important nutrients
in addition to the energy.
Sign -- An indicator of disease found in physician's examination or
tests; and objective indicator of disease. Cf. symptom.
Skeletal muscle -- Muscle that attaches to the skeletal system and
causes body movement by a shortening or pulling action against its bony
attachment.
Slow-twitch fibers -- Muscle fiber type that contracts slowly and
is used most in moderate-intensity, endurance exercises, such as distance
running. Cf. fast-twitch fibers.
Smooth muscle -- Involuntary muscle tissue found in the walls of
almost every organ of the body.
Snatch -- Olympic lift where weight is lifted from floor to
overhead (with arms extended) in one movement.
Somatotype -- (see Endomorph, Ectomorph and Mesomorph)
Sodium -- An essential mineral for proper growth, and nerve and
muscle tissue function. A diet high in salt (40% of salt is sodium) causes
a potassium imbalance and is associated with high blood pressure. No RDA.
Dietary sources: salt, shellfish, celery, beets, artichokes.
Spasm -- The involuntary contraction of a muscle or muscle group in
a sudden, violent manner.
Specificity -- The principle that the body adapts very specifically
to the training stimuli it is required to deal with. The body will perform
best at the specific speed, type of contraction, muscle-group usage, and
energy-source usage it has become accustomed to in training.
Speed-Strength -- A type of strength typically referred to as
power. Power, however, is an inadequate term as it does not differentiate
between the two important types of speed-strength.
1. Starting strength involves turning on a maximum number
of muscle fibers instantly in any given movement. Ballistic athletes, such
as a sprinter, need this strength the most to make his muscles fire
simultaneously with each stride. A boxer does the same with each punch, a
baseball pitcher each time he hurls.
2. Explosive strength describes the firing of muscles
fibers over a longer period of time after initial activation, for the
purpose of pushing, pulling or moving a weighted object. Examples:
weightlifting, shotputting and football.
Spinal nerves -- The 31 pairs of nerves radiating outward from the
spinal cord which relay impulses to and from the skeletal muscles.
Spot reducing -- An effort to reduce fat at one location on the
body by concentrating exercise, manipulation, wraps, etc. on that
location. Though there are some minor exceptions, research indicates that
any fat loss is mostly generalized over the body, however.
Sprain -- A stretching or tearing of ligaments. Severity ratings of
sprains are: first-degree, partial tearing; third-degree, complete tears.
Cf. strains.
Squats -- An upper leg and hip exercise usually performed with a
barbell resting on the shoulders, and a deep knee bend is performed; the
squatter then returns to an erect standing position. There are several
methods of squatting, each having its own unique advantages and
disadvantages. The squat is also one of the three lifts contested in the
sport of powerlifting.
Stabilizer -- A muscle that stabilizes (or fixes) a bone so that
movement can occur efficiently at another bone articulating with the
stabilized bone.
Starch -- Starch is a polysaccharide made of glucose linked
together. The body must convert starch into glucose which can be utilized
for immediate energy or converted to glycogen and stored in the liver for
later energy needs. It exists throughout the vegetable kingdom, its chief
commercial sources being the cereals and potatoes.
Static contraction -- See isometric action.
Steady state -- The physiological stare, during submaximal
exercise, where oxygen uptake and heart rate level off, energy demands and
energy production are balanced, and the body can maintain the level of
exertion for an extended period of time.
Steroids -- Naturally-occurring and synthetic chemicals that
include some hormones, bile acids, and other substances. See anabolic
steroids.
Straight sets -- Groups of repetitions (sets) interrupted by only
brief pauses (30-90 seconds).
Strain -- A stretching or tearing of a musculotendinous unit.
Degrees of severity include: first-degree, stretching of the unit;
second-degree, partial tearing of the unit; third-degree, complete
disruption of the unit. Cf. sprain.
Strength -- The application of muscular force in any endeavor
(speed and distance are
not factors of strength) -- such as to a barbell, a ball, or to the
ground underfoot. There are 5 broad categories of strength, each with its
own special training requirements: absolute, limit, speed, anaerobic
and aerobic.
There are many different factors that affect strength, and they fall
into 4 broad categories:
1. Structural/Anatomical: muscle fiber arrangement,
musculoskeletal leverage, ratio of fast- vs. slow-twitch fibers, tissue
leverage, motion-limiting factors (scar tissue and adhesions), tissue
elasticity, intramuscular\intracellular friction, and others.
2. Physiological/biochemical: stretch reflex, sensitivity
of the Golgi tendon organ, hormonal function, energy transfer systems
efficiency, extent of hyperplasia (muscle splitting), myofibrillar
development, motor unit recruitment, cardiovascular and cardiorespiratory
factors, and others.
3. Psychoneural/learned responses: "psych" (arousal level), pain
tolerance, "focus" (concentration), social learning, "skill"
(coordination), spiritual factors, and others.
4. External/environmental: equipment, weather and altitude,
gravity, opposing and assistive forces.
The foregoing discussion notwithstanding, a more traditional
way(despite being less precise) of classifying strength is to divide it
into general, specific and special categories:
General strength. In this category, you train all the muscle groups
without concentrating on the muscles that assist your particular event.
Training for general strength will give you a base for your event -
specific strength.
Specific strength. Training for specific strength is an
intermediate type of training that takes into consideration only one
aspect of a specific demand. It has an important function in joining
general and special strength training together.
Specific strength will help you improve your techniques as you develop
the strength needed to execute the exact movements of your event, whether
they are jumping, throwing, or running.
In other words, once you have developed general (overall) body
strength, you should then work on the strength of the particular muscle
groups that will be most involved when you perform the event in which you
compete.
Special strength. The term special, as it is used here, means
"specialized." Each sport or event requires a specialized type of
strength. Shot putters, for example, need starting strength and explosive
strength, while wrestlers need anaerobic strength endurance. While the
exercises for building specific strength are often of different intensity
and duration than those of the typical agnostic movement, the exercises
done for special strength training have to reflect all the components of
the agnostic movement.
The base of special strength drills is represented by the complete
movement in that the development of the most peculiar physical properties
(strength, speed, endurance) is applied. When strength training is poured
into the complete movement, respecting its dynamical-mechanical
characteristics, it is called "special strength training."
Strength training -- Using resistance weight training to build
maximum muscle force is the traditional way of defining the practice of
strength training. However, a more global definition would account for the
metabolic circumstances under which force is being applied (i.e., the
energy contribution from ATP/CP, glycolytic or oxidative sources).
Stress -- The general physical and psychological response of an
individual to any real or perceived adverse stimulus, internal or
external, that tends to disturb the individual's homeostasis. Stress that
is excessive or reacted to inappropriately, may cause disorders.
Stress fracture -- A partial or complete fracture of a bone bec
ause of the remodeling process's inability to keep up with the effects of
continual, rhythmic, nonviolent stresses on the bone. Cf. overuse.
Stress management -- A group of skills for dealing with stresses
imposed on an individual
without suffering psychological distress and/or physical
disorders.
Stress test -- See graded exercise test.
Stretching -- Lengthening a muscle to its maximum extension; moving
a joint to the limits of its extension.
Stretch reflex -- To prevent overextension and serious injury to
muscles and tendons, muscles are equipped with specialized nerve cells
(spindles) that "apply the brakes" when elasticity maximum is reached.
Careful ballistic training augmented with plyometric drills can heighten
the threshold of the stretch reflex mechanism and improve
strength-generating ability.
Striations -- Grooves or ridge marks of muscles' individual
myofibrils visible through the skin, and resulting from both hypertrophy
training and extremely low subcutaneous fat deposits; the ultimate degree
of muscle definition.
Stroke volume -- The volume of blood pumped out of the heart into
the circulatory system by the left ventricle in one contraction.
Submaximal -- Less than maximum. Submaximal exercise requires less
than one's maximum
oxygen uptake, heart rate, or anaerobic power. Usually refers to
intensity of the exercise, but may be used to refer to duration.
Succinates -- Succinic acid's biological activities are varied.
Their chief function is in their enzyme activity, but they also combine
with protein to rebuild muscle fiber and nerve endings, and help fight
infection.
Sucrose -- Sucrose is a sweet disaccharide that occurs naturally in
most land plants and is the simple carbohydrate obtained from sugarcane,
sugar beet and other sources. It is hydrolyzed in the intestine by sucrase
to glucose and fructose.
Sulfur -- A mineral of major structural importance to proteins,
enzymes, antibodies, skin and hair. No RDA. Dietary sources: beans, beef,
eggs.
Superset -- Alternating back and forth between two exercises until
the prescribed number of sets is completed. The two exercises generally
involve a protagonist and antagonist (e.g., the biceps and triceps, or the
chest and upper back); however, common usage of the term also can mean any
two exercises alternated with one another.
Supination -- Assuming a horizontal position facing upward. In the
case of the hand, it also means turning the palm to face forward. The
opposite of pronation.
Supplements -- Any enterally (taken into the body by mouth) or
parenterally (taken into the body other than by mouth) administered
substance which serves health, ergogenic, growth or other bodily processes
which food alone either cannot accomplish or cannot accomplish as
efficiently is referred to as a supplement. Supplements can be nutritional
or non-nutritional in nature. The traditionally identified classifications
of supplements are health foods, additives, herbals (botanicals),
nutriceuticals (engineered foods), micronutrients, macronutrients,
adaptogens (bodily adaptation enhancers), ergogenic (work enhancing)
compounds and anabolic (growth enhancing) compounds. See Nutriceutical.
Symptom -- Any evidence by which a person perceives that he/she may
not be well; subjective evidence of illness. Cf. sign.
Syncope -- Fainting. A temporary loss of consciousness from
insufficient blood flow to the brain.
Syndrome -- A group of related symptoms or signs of disease.
Synergism -- The combined effect of two or more parts of forces or
agents which is greater than the sum of the individual effects. Example:
the synergistic effect of a multiple vitamin and mineral formula compared
to the benefits of one or two vitamins.
Systole -- The contraction, or time of contraction, of the heart.
Cf. diastole.
Systolic blood pressure -- Blood pressure during the contraction of
the heart muscle. Cf. blood
pressure.
Tachycardia -- Excessively rapid heart rate. Usually describes a
pulse of more than 100 beats per minute at rest. Cf. bradycardia.
Taper down - See cool down.
Target heart rate (THE) -- The heart rate at which one aims to
exercise at a THR of 60 to 90 percent of maximum heart rate
reserve.
Tendon -- A band or cord of strong, fibrous (collagenous) tissue
that connects muscles to bone.
Tendonitis -- Inflammation of a tendon.
Testing protocol -- A specific plan for the conducting of a testing
situation; usually following an accepted standard.
Testosterone -- The sex hormone that predominates in the male, is
responsible for the development of male secondary sex characteristics and
is involved in the hypertrophy of muscle. Cf. estrogen. Anabolic steroids
are synthetic chemicals that mimic the muscle-building effects of
testosterone. Testosterone is an androgen, a sex hormone produced by all
humans. It is important in the development of male gonads and sex
characteristics. In females, testosterone is an intermediate product in
the production of estradiols.
As a pharmaceutical drug, it is used to stimulate sex characteristics,
to stimulate production of red blood cells, and to suppress estrogen
production. Long-term use can lead to kidney stones, unnatural hair
growth, voice changes, and decreased sperm count.
Therapy -- Related to fitness and sports, therapy is the
application of a substance or technique in the prevention, management, and
treatment of common athletic injuries and related problems. Many of the
means available also play a role in enhanced recuperation after training
sessions, which obviously leads to improved performances. Some of the
therapeutic means in current use are strictly the domain of the sports
medicine physician or a licensed physical therapist, while others can be
safely applied by coaches and trainers, or even by the athletes
themselves. Here are a few of the more common ones:
1. Diathermy: A professional therapeutic modality, diathermy is a form
of high-frequency heat that penetrates injured tissues deeper and more
effectively than other forms of heat therapy (e.g., hydroculator packs,
moist-heat packs, etc.). Where other modalities penetrate between
one-eighth to one-fourth inch at best, diathermy reaches 1-1/2 to 2-1/2
inches into the injured tissues. Diathermy increases vasodilation (blood
supply) needed both for carrying nutrients to and waste products away from
injured tissues. Unlike other forms of heat therapy, diathermy's
circulating heat does not produce static swelling at the treatment site.
Note: All forms of heat therapy should be followed by cryotherapy, or cold
treatment.
2. Electrostimulation: Typical use involves electrodes that create a
contraction of the surrounding musculature, reducing edema by pumping
fluid out of the affected tissue. An atypical application (but a very
effective method of reducing edema) pioneered by former Eastern Bloc
sports medicine specialists involves placing the electrodes not on the
muscles, but
directly on the joint. Moderate to intense amounts of intermittent
stimulation are applied for 10 to 15 minutes per session. This type of
transarticular electrostimulation is most effective when implemented
immediately after diathermy and followed by cryotherapy and elevation.
3. Cryotherapy: The application of cold (usually in the form of ice or
"chemical ice") to body tissues for the purpose of pain relief and
decreased swelling (via vasodilation). Typical use involves hourly
applications of 10 to 15 minutes in duration. Ice is simple, inexpensive,
and effective and can be applied without professional assistance.
4. Heat Therapy: Heating pads or hot showers are best when followed
with ice because heat alone causes static swelling. Leaving a heating pad
on all night is the worst treatment possible because it creates static
edema. Never use heat sooner than 48 to 72 hours after an injury. When it
is used, it should be used for only 10 to 15 minutes along with active
stretching of
the body part being heated, followed by 10 to 15 minutes of ice and
stretching of the affected area. Hot showers are great in the morning and
after workouts to bring blood into the tissue, but the shower should be
turned progressively cooler to cold in order to dissipate any swelling
caused by heat.
5. Ultrasound: High frequency sound waves which oscillate to penetrate
1 to 2-1/2 inches into muscle tissue. Ultrasound loosens or breaks up scar
tissue and tight fibrous adhesions due to injury. Frequently used in most
musculoskeletal ailments.
6. Hydrotherapy: The use of water as a therapeutic/recuperative
means.
The most common forms are:
* Contrast Showers: Done immediately after training to expose the
area to alternating bursts of hot and cold water. Comfortably hot for 2
to
3 minutes, followed by 2 minutes of progressively colder water up to
the
point of discomfort. This procedure is then repeated for 4 to 6
cycles.
Since hot water is a vasodilator and cold water a vasoconstrictor, the
net
effect of contrast showers is vastly improved circulation to the
affected
areas. The effectiveness of contrast showers is markedly increased when
combined with stretching. Various types of trunk stretches, including side
bends as
well as flexion and extension, can be performed. Quadriceps, hamstring,
and
pectoral stretches can also be performed after training sessions for
these
muscle groups. Stretches are repeated for each contrasting cycle. A
handrail and nonslip rubber "skids" must be used for safety.
* Contrast Baths: Applied in the same manner and for the same
purpose as contrast showers. Contrast baths, however, are more
convenient
for localized use (e.g., treating a limb instead of the entire
body).
* Whirlpool: This form of therapy improves circulation and
renders a relaxation effect. Can be used for general or localized
purposes.
Water temperature should stay between 102-103º F (28-35º C). Limit
immersion to 15 minutes or less. Avoid whirlpool if there is a
swollen
joint or joints.
7. Cryo-kinetics for Low Back and Leg Recuperation: An ice pack can
be
constructed by placing crushed ice in a "zip-lock" bag. Immediately
after leaving the shower, the individual should lie down on the floor with
his feet propped over a bed or couch and the ice pack under his lumbar
spine. To improve the effect of this procedure tri-fold, he should stretch
his
spine while on the ice and gently perform lateral (side to side)
flexions alternated with pulling his knees to his chest. Mobilizing the
spine in this way will counteract any stiffening effects from icing the
back. Cryo-kinetic therapy is very beneficial in reducing contracted,
tightened
muscle tissue as well as pumping these tissues free of accumulated,
training-induced waste products. At least 15, but no longer than 20,
minutes should be spent on the ice. This is most effective when done
immediately after contrast showers.
8. Leg Elevation: Used as a means to reverse hydrostatic or columnar
pressure after a long day standing or training. Leg elevation is
particularly effective prior to training, and the effects are improved at
least twofold when used concurrent with cryotherapy on the knees. For
greatest effectiveness, elevate the legs for about 20 minutes, keeping
them perpendicular to the floor while lying on the back.
9. Ongoing Professional Assistance: Many forms of therapy, including
various types of "bodywork," are available to athletes at moderate cost
and are highly recommended. The most commonly used forms of professional
assistance are:
* Chiropractic * Massage Therapy
* Physical Therapy * Rolfing
* Neuromuscular Re-education * Tragering
* Acupuncture/pressure * Alexander Technique
Tiron -- Tiron (Sodium-4,5-dihydroxybenzene-1,3-disulfonate) is a
chelator mentioned in the research literature which effectively clears
vanadium from body tissues right from the first day of use. It is
currently not available in supplement form. (See vanadyl sulfate.)
Tissue elasticity -- Tissue elasticity ("viscoelasticity") is
involved in all explosive sports, including shot put, boxing, the baseball
and javelin throw, and powerlifting. After being stretched, most bodily
tissues -- including muscles, but not so much with ligaments and tendons
-- return to their original shape or length. The quicker they do, the more
force there is added to the forcee output stemming from both stretch
reflex and muscle contraction.
Tissue (or interstitial) leverage -- The degree of extra mechanical
advantage gained by superheavyweight strength athletes by packing sheer
mass from extra fat, liquid and protein between and inside muscle
fibers.
Torque -- Moment of force; The turning or twisting effect of a
force.
Training -- Subjecting the body to repeated stresses with
interspersed recovery periods to elicit growth in its capacity to handle
such stresses.
Training effect -- Increase in functional capacity of muscles and
other bodily tissues as a result of increased (overload) placed upon
them.
Training technologies -- Athletes can tap into eight broad
categories of accepted methods to attain performance goals: weight
training, light resistance training, medical support, therapeutic
modalities (jacuzzi, massage,acupuncture, etc), psychological support,
biomechanics, diet and nutritional supplements.
Training to failure -- Continuing a set in weight training until
inability to complete another rep without assistance.
Training zone -- See target heart rate.
Transcendental Meditation (TM) -- An effortless meditation
technique scientifically shown to sweep away energy-sapping mental and
physical stress and deep-rooted fatigue. Among athletes it improves
energy, reaction time, workout recovery, mental alertness and
coordination.
Traps -- Slang for trapezius muscles, the largest muscles of the
back and neck that elevates the shoulder girdle and draws the scapulae
medially.
Triceps brachii -- The muscles on the back of the upper arm are the
prime movers for extending the elbow.
Trimming down -- Gaining hard muscular appearance by losing body
fat (a more contemporary phrase is "trimming and toning").
Troponin -- A protein that reacts with calcium to set the
contractile mechanism into action within muscle fibers.
Triglyceride -- Triglycerides are a combination of glycerol with
three fatty acids: stearic acid, oleic acid, and palmitic acid.
Twitch -- A brief muscle contraction caused by a single volley of
motor neuron impulses. Cf. fast-twitch fibers, slow-twitch fibers.
Universal machine -- One of several types of weight lifting devices
where weights are on a track or rails and are lifted by levers or pulleys.
Deveeloped in the early 60s by Chuck Coker, the phrase originally referred
to a multi-station gym.
Unsaturated fatty acids (UFA) -- UFAs are important in lowering
blood cholesterol and may thus help prevent heart disease. They are
essential for normal glandular activity, healthy skin, mucous membranes
and many metabolic processes.
Unsaturated fatty acids (UFA) are fatty acids whose carbon chain
contains one or more double or triple bonds, and which are capable or
receiving more hydrogen atoms. They include the group polyunsaturates, are
generally liquid at room temperature and are derived from vegetables,
nuts, seeds or other sources. Examples of unsaturated fatty acids include
corn oil, safflower oil, sunflower oil and olive oil. Replacing saturated
fats with unsaturated fats in the diet can help reduce cholesterol
levels.
A small amount of highly unsaturated fatty acid is essential to animal
nutrition. The body cannot desaturate a fat, such as vegetable shortening
or margarine, sufficiently by its own metabolic processes to supply this
essential need. Therefore, the dietary inclusion of unsaturated or
polyunsaturated fats is vital.
The three essential fatty acids (those which the body is unable to
manufacture) are linoleic acid, linolenic acid, and arachidonic acid.
However, these fatty acids can be synthesized from linoleic acid if
sufficient intake occurs. Linoleic acid should provide about 2% of total
dietary calories. Corn, safflower and soybean oils are high in linoleic
acid.
Cf. monounsaturated fat, polyunsaturated fat, saturated fat.
Upper abs -- Abdominal muscles above navel (see lower abs).
Valsalva maneuver -- Valsalva Maneuver -- If the glottis (the
narrowest part of the larynx) is closed following full inspiration and the
expiratory muscles are fully activated, the compressive forces of
exhalation can increase the intrathoracic pressure from 2 or 3 mm Hg to
upwards of 100 mm Hg above atmospheric pressure. This forced exhalation
against a closed glottis is called the Valsalva maneuver (named after the
Italian anatomist who first explained the phenomenon), and is common in
weightlifting or other activities requiring short rapid maximum force
Session. The intrathoracic pressure causes the veins to compress and
this in turn results in significantly reduced venous blood flow into the
heart and into the brain. Dizziness, "spots" before the eyes and blackout
can ensue. This is one good reason why those with cardiac problems should
refrain from all-out straining (as in isometric contraction), and insterad
should engage in a more rhythmic type of weightlifting technique.
Vasoconstriction -- The narrowing of a blood vessel to decrease
blood flow to a body part.
Vasodilation -- The enlarging of a blood vessel to increase blood
flow to a body part.
Vanadyl Sulfate -- Vanadyl sulfate (VOSO4) has been very
extensively studied for its insulin-like activity as a blood glucose
lowering agent. In other words, vanadyl sulfate dramatically increases
glucose uptake by your muscle cells. There are many benefits:
- Increased energy for workouts;
- More rapid recovery following workouts;
- Muscle glycogen (what glucose becomes when stored in your muscles) is
more abundant, thereby providing a protein-sparing effect;
- This protein-sparing effect provides for better protein synthesis
(muscle growth and repair);
- Increased storage of muscle glycogen provides a fuller, more dense
appearance to your visible muscles.
Care must be taken with this substance however. Vanadium can build up
in various tissues of the body, especially the kidneys. Tiron (see Tiron)
is the only known chelator capable of eliminating this danger, although
vitamin c, glutathione and other antioxidants can help.
Variable resistance -- Strength training equipment which can,
through the use of elliptical cams and other such technology, vary the
amount of weight being lifted to match the strength curve for a particular
exercise. Nautilus machines, for example, provide this feature. (See
Constant Resistance and Accommodating Resistance.)
Variable Split Training -- A weight training system developed in
the mid 80s by Dr. Fred Hatfield that systematizes workout schedules
according to the recuperation of individual muscle groups and body parts.
This method maximizes development by eliminating effects of overtraining
or undertraining. Also Variable Double Split and Variable Triple Split for
multiple daily workouts.
Vascularity -- Increase in size and number of observable veins.
Highly desirable in bodybuilding.
Vein -- A vessel which returns blood from the various parts of the
body back to the heart.
Ventilation -- Breathing. Cf. expiration, inspiration,
respiration.
Vertigo -- Sensation that the world is spinning or that the
individual is revolving; a particular kind of dizziness.
Vital capacity -- Maximal breathing capacity; the amount of air
that can be expired after a maximum inspiration; the maximum total volume
of the lungs, less the residual volume.
Vital signs -- The measurable signs of essential bodily functions,
such as respiration rate, heart rate, temperature, blood pressure,
etc.
Vitamins -- A number of unrelated organic substances that are
required in trace amounts for the metabolic processes of the body, and
which occur in small amounts in many foods.
Vitamin -- Organic food substances present in plants and animals,
essential in small quantities for the proper functioning of eveeery organ
of the body, and for all energy production. Most are obtained from food,
but supplementation is almost always advised, and regarded as critical for
athletes in heavy training.
Vitamin A -- A fat-soluble vitamin occurring as preformed vitamin A
(retinol), found in animal origin foods, and provitamin A (carotene),
provided by both plant and animal foods. Maintains healthy skin, mucous
membranes, eyesight, immune system function, and promotes strong bones and
teeth. Vital to the liver's processing of protein. RDA: 5,000
International units. Dietary sources: fish liver oil, liver, eggs, milk
and dairy, green and yellow vegetables, and yellow fruits.
Vitamin B complex -- Vitamin B-Complex -- A family of 13
water-soluble vitamins, probably the single-most important factor for the
health of the nervous system. They are essential to the conversion of food
into energy. When you exercise strenuously, your body quickly burns up its
vitamin B supply. A shortage of Bs affects both performance and recovery.
High consumption of sugar, caffeine, processed food and alcohol cause
depletion. These vitamins are grouped together because of their common
source, distribution, and their interrelationship as coenzymes in
metabolic processes. The best food source for vitamin B-complex is
Brewer's yeast. All must be present together for the B-complex to work.
Vitamin B-complex consists of the following vitamins:
Biotin
Choline
Inositol
Vitamin B-1 (thiamine)
Vitamin B-2 (riboflavin)
Vitamin B-3 (niacin)
Vitamin B-5 (pantothenic acid)
Vitamin B-6 (pyridoxine)
Vitamin B-9 (folacin)
Vitamin B-12 (cyanocobalamin)
These vitamins are grouped together because of their common source,
distribution, and their interrelationship as coenzymes in metabolic
processes. The best food source for vitamin B-complex is Brewer's yeast.
All must be present together for the B-complex to work.
Vitamin B-1 (thiamine) -- Essential for learning capacity and
muscle tone in the stomach, intestines and heart. RDA: 1.4 mg (men), 1.0
mg. (women). Dietary sources: brewer's yeast, wheat germ, blackstrap
molasses, whole wheat and rice, oatmeal, most vegetables.
Vitamin B-2 (riboflavin) -- An essential co-factor in the enzymatic
breakdown of all foodstuffs. Important to cell respiration, good vision,
skin and hair. RDA: 1.6 mg. Dietary sources: liver, tongue, organ meats,
milk, eggs. The amount found in foods is minimum, making this America's
most common vitamin deficiency.
Vitamin B-3 (niacin) -- Essential for synthesis of sex hormones,
insulin, and other hormones. Effective in improving circulation and
reducing blood cholesterol. RDA: 19 mg. (men), 13 mg. (women). Dietary
sources: lean meats, poultry, fish and peanuts.
Vitamin B-5 (pantothenic acid) -- An important stress, immune
system and anti-allergy factor. Vital for proper functioning of adrenal
glands, where stress chemicals are produced. Promotes endurance. RDA: 10
mg. Dietary sources: organ meats, egg yolks, whole-grain cereals.
Vitamin B-6 (pyridoxine) -- Essential for the production of
antibodies and red blood cells, and the proper assimilation of protein.
The more protein you eat, the more B-6 you need! Facilitates conversion of
stored liver and muscle glycogen into energy. RDA: 1.8 mg. (men), 1.5 mg.
(women). Dietary sources: brewer's yeast, wheat bran, wheat germ, liver,
kidney, cantaloupe.
Vitamin B-12 (cobalamin) -- Necessary for normal metabolism of
nerve tissue and formation and regeneration of red blood cells. RDA: 3
micrograms. Dietary sources: animal protein. Liver is the best.
Vitamin C -- A critical health-protection nutrient. Body stores are
depleted rapidly by drugs, toxins, smoking, exercise and stress. Fortifies
the immune system against virus infections, strengthens blood vessels,
reduces cardiovascular abnormalities, lowers fat and cholesterol levels,
as a natural anesthetic it reduces many kinds of pain, helps detoxify
chemical and metal contaminants found in the air, water and food, slows
down lactic acid buildup, helps heal wounds, scar tissue and injuries.
Necessary in the formation of connective tissue. RDA: 60 mg, but tolerated
in doses exceeding 10,000 mg (10 grams) daily. Dietary sources: citrus
fruits, berries, green and leafy vegetables, tomatoes, potatoes.
Vitamin D -- A fat-soluble vitamin, acquired through sunlight or
diet. Aids the body in utilization of vitamin A, calcium and phosphorus.
Helps maintain stable nervous system and normal heart action. RDA: 400
International units. Dietary sources: fish-liver oils, sardines, salmon,
tuna, milk and dairy.
Vitamin E -- This fat-soluble vitamin is an active anti-oxidant
retarding free-radical damage, as well as protecting oxidation of fat
compounds, vitamin A, and other nutritional factors in the body. Important
to cellular respiration, proper circulation, protection of lungs against
air pollution, and prevention of blood clots. Helps alleviate leg cramps
and "charley horse." RDA: 15 International units (men), 12 (women).
Dietary sources: wheat germ, cold-pressed vegetable oils, whole raw seeds
and nuts, soybeans.
Vitamin K ("Koagulation") -- This vitamin is implicated in proper
blood clotting. It is synthesized in the intestinal flora. Because it is
fat-soluble, it has the potential for toxicity if taken in large doses.
There is no established RDA.
o(V,.)O2 max -- Maximum Volume of Oxygen consumed per unit of time.
In scientific notation, a dot appears over the V to indicate "per unit of
time." Cf. maximal oxygen uptake.
Warm-up -- A gradual increase in the intensity of exercise to allow
physiological processes to prepare for greater energy outputs. Changes
include: rise in body temperature, cardiovascular- and respiratory-system
changes, increase in muscle elasticity and contractility, etc. Flexibility
exerecises and stretching are NEVER advised as a warm-up strategy because
of the damage that is easily caused to cold muscles.
Watt -- A measure of power equal to 6.12 kilogram-meters per
minute.
Weightlifter's headache -- An exertional type of pain which may be
due to intense clenching of the jaws during heavy lifts.
Weightlifting -- An Olympic sport where athletes compete in defined
weight classes to lift the most weight overhead. The two lifts contested
are the snatch and the clean and jerk. Three attempts are given in each of
the two lifts. See Olympic lifts.
Weight training -- Exercise that utilizes progressive resistance
movements to build strength. Practiced intensely by powerlifters,
weightlifters and bodybuilders in particular, and by all athletes
interested in developing any form of strength.
Weight training belt -- Thick leather belt developed by
weightlifters in the early part of the century, usually 4 inches wide in
the back and 2 inches wide in the front, used to support lower back while
doing squats, military presses, dead lifts, bent rowing, etc. Powerlifters
opt for a belt that's 4 inches wide all the way around. New research which
compares the level of support afforded the lumbar spine during lifting,
however, clearly shows that a belt which covers the abdominal wall between
the lower ribs and the pelvis, and with a more comfortable narrow belt
going around the back, is far superior to the belts traditionally worn.
This new belt is called a "LORA" (acronym for Lumbar Orthopedic
Repositioning Appliance).
Wellness -- A state of health more positive than the mere absence
of disease. Wellness programs emphasize self-responsibility for a
lifestyle process that realizes the individual's highest physical, mental,
and spiritual well-being.
Wet-bulb thermometer -- A thermometer whose bulb is enclosed in a
wet wick, so that evaporation from the wick will lower the temperature
reading more in dry air than in humid air. The comparison of wet-and
dry-bulb readings can be used to calculate relative humidity. Cf. dry bulb
thermometer, wet-globe temperature.
Wet-globe temperature --A temperature reading that approximates the
heat stress which the
environment will impose on the human body. Takes into account not only
temperature and humidity, but radiant heat from the sun and cooling
breezes that would speed evaporation and convection of heat away from the
body. Reading is provided by an instrument that encloses a thermometer in
a wetted, black copper sphere. Cf. dry-bulb thermometer, wet-bulb
thermometer.
Whey -- A milk byproduct with a biological value of 80-88. In
recent years, clinical scientists have improved the BV by enzymatically
altering the bonds between the amino acids forming the protein complex.
Called "engineered" whey, the BV is slightly higher than eggs. See
BV
White Blood Cell -- White blood cells are nucleated cells,
originating from the bone marrow, that make up the infection-fighting
components of the blood. White blood cells fight infections by producing
antibodies, releasing immune factors, or ingesting invading bacteria or
viruses.
Work -- Force times distance. Measured in foot-pounds and similar
units. Example: Lifting a 200-pound barbell 8 feet and lifting a 400-pound
barbell 4 feet each require 1,600 foot-pounds of work.
Work measures -- See foot-pounds, kilogram-meters.
Workout -- A complete exercise session, ideally consisting of
warm-up, intense aerobic and/or strength exercises, and cool-down.
Workrate -- Power. The amount of work done per unit of time. Can be
measured in foot-pounds per second, watts, horsepower, etc.
Xiao Pangmei -- pronounced "shou-pang-may" -- "XPM" for short) was
recently put to a single blind test by Drs. Qin Zhengyu ((physiologist)
and Xu Aihua (endocrinologist), both researchers at the First Military
Medical University in China. These researchers noted a highly significant
body fat reduction in comparison to a control group and a placebo group,
which, upon further testing they discovered had resulted from:
