Complete
Fitness: What’s Healthy Exercise?
Frederick C.
Hatfield II, MS, MFS, CSCS
In a previous
article (“Exercise And The Press”) I reported on research noting that higher
amounts of exercise had higher benefits then lesser amounts. The point of that article was how the media
still sang the praises of low intensity exercise despite the findings of the
study. Five months later, new research
notes that a little exercise may not be worthwhile at all. Do you think this may finally change the
minds of the “light fitness crowd?” It
doesn’t appear so!
Amanda Dunn of
the “Health Reporter” (“Walking for Heart May be an Exercise in Futility”,
April 16, 2003) reports that the “even a little exercise is good” line of
thought is being challenged by research in the British Journal, “Heart”.
To summarize
the findings, “light” fitness activities such as walking, bowling and sailing
do very little to protect from cardiovascular disease and to reduce the risk of
death. For the record, moderate
exercise was described as golf, digging and dancing, while heavy exercise was
described as climbing stairs, swimming and jogging.
Even though
this study claims that light fitness activities do very little, Dunn’s article
notes that other scientists STILL claim that it’s beneficial or as they put it,
“better than none”. A cardiologist
quoted in the article, David Hare, suggests the most beneficial level of
exercise occurs when breathing is elevated, but a normal conversation can be
held.
What could possibly
keep these fitness experts (are cardiologists “fitness experts?”) from the idea
of vigorous exercise? The answer is
clear: in their field they are worried
about the heart. Their fear is that
people will over exert themselves and have a heart attack. Of course, that is a reasonable concern;
however they are still ignoring that their “light exercise” isn’t doing the
job. Furthermore, is this the only
fitness concern? The International
Sports Sciences Association has identified 16 components of fitness. These are: 1.
Limit
strength 2.
Starting
strength 3.
Explosive
strength 4.
Agility 5.
Flexibility 6.
Static
Balance 7.
Dynamic
Balance 8.
Local
Muscular Endurance 9.
Speed
Endurance 10. Cardiovascular Endurance 11. Muscle Mass 12. Percent Body Fat 13. Freedom from stress 14. Freedom from disease 15. Preventive lifestyle (includes
proper nutritional habits and reducing risk factors) 16. Mind/Body/Spirit Connection –
Being “at peace” with yourself Even for the average
“Mr. And Mrs. Jones”, all components of fitness have an effect on preventing
cardiovascular disease. With this in
mind, the following table charts how the components of fitness help prevent
cardio vascular disease. The effects of
“light exercise” has on each of the components (based on the studies documented
in recent studies) is also noted. How The Components
of Fitness Help Prevent Cardiovascular Disease
Agility, balance and
speed endurance may play an indirect effect by providing components needed for
enjoyable activities. What Are We Doing
About It? According to
SGMA International here are the top 30 fitness and outdoor activities in the
U.S. (age 6 and above). Below is a
listing of the activities (in order of their popularity) and the possible (even
if it’s remotely possible) benefits of each.
Of course, many are dependant how vigorously you engage in them. For example, fitness walking could be a
brisk walk (getting your heart rate up to acceptable levels) or it could be a
simple leasure walk. The components involving stress levels are not listed as
it is assumed you enjoy doing them.
Components of
Fitness In The Most Popular Fitness and Outdoor Activities
Concluding Thoughts: I am in full agreement that
exercise and fitness must be viewed on a case by case basis. For some individuals getting out of a chair
is not “light” exercise, but rather a difficult task. If fitness levels are going to increase in any individual, they
must go beyond what is “light” exercise for them. Furthermore, using cardiovascular guidelines as standards of
fitness is inadequate. Heart rates and
respiratory rates do play a part in detecting levels of fitness, but all 16
components play a part in prevention of cardiovascular disease to some extent. Furthermore, in terms of quality of life and
actually exercising, they are all important as the second table shows (though
some parts are a bit tongue-in-cheek). The media and the scientists
whose research I quoted should carefully reconsider singing the praises of
“light” exercise. The intensity of the
exercise should be increased over time and should be monitored by a competent
exercise expert. Staying in the “light”
exercise category and saying it’s “good” is like staying educated at the middle
school level (never going to high school or beyond) and claiming that IT is
good. I have no doubt media trends
will continue to focus on cardiovascular health as it is important. However, it is the prescription of what is needed
that should be considered. |
