Tai Chi For Health
Both my parents are doctors, so from an early age I was the recipient
of whatever pill, injection or potion that came on the market. This
has given me a uniquely jaundiced view of the dark science of medicine
and the shamans who practice it. The hands that heal are of value in
a great number of instances, but in a number of others are either of
little value or are even dangerous.
A couple of years ago one of my Chinese female students complained of
stomach pains so her mother sent her to a traditional Chinese doctor
who gave her bowls of a foul tasting potion to drink saying that the
cause of her sickness was bad Chi. After a few days the pain got worse
so I advised her to go to hospital. At the first hospital casualty department
she was told that she was pregnant, which she wasn't; at the second
they diagnosed acute appendicitis and operated the same day.
We have to consider that while an individual may be entitled to call
himself doctor as a result of graduating bottom of his medical class
thirty years ago from some God-forsaken university, this hardly puts
him in the best position to provide his patients with treatment using
the cutting edge of new technology.
As far as traditional Chinese medicine and alternative medicicne are
concerned the picture is murkier still. At least with a properly qualified
Western doctor you are sure that he has a certain basic knowledge and
training. Often in Chinese stories and films there is the character
of the itinerant traditional Chinese doctor. One of the reasons that
some of these gentlemen were itinerant doctors was so that they weren't
around to suffer retribution at the hands of unsatisfied customers.
Doctors on the whole take a dim view of martial arts injuries (it's
your own fault), particularly if the patient is a hip young dude with
an attitude problem and often advise complete rest where this is quite
inappropriate. In fact the person with an attitude problem is the doctor
as such advice is not only unhelpful and complacent, but in some instances
woefully wrong. Fortunately a few more enlightened practitioners are
more open minded about the benefits of exercise and there are now some
sports medicine clinics around the country doing a good job.
I decided to write on this subject after chatting to one of my students,
Dr. Mike Webb, who is a medical researcher. While helping me to research
some material for my forthcoming book on the Tai Chi Chuan Classics,
Mike came across some interesting studies on exercise in general and
Tai Chi Chuan in particular and their effect on the body. I should add
that I have certain reservations about some of the Tai Chi related studies,
but I'll bring this up later.
Firstly I'd like to deal with material on exercise in general with specific
regard to its effect on bones. The first study - of 39 postmenopausal
sedentary, estrogen deplete white women aged from 50-70 years of age
was made at the Human Nutrition Research Center on Aging at Tufts University,
Boston, Maryland. Twenty women were given five different high intensity
strength training exercises two days per week for one year, while the
other group were untreated. The study found that muscle mass, muscle
strength and dynamic balance increased while bone density was preserved
in the strength trained group but all these factors decreased in the
untreated group.
Next was a study over 2 years of a 26 year old female by the Bone Research
Group, UKK Institute, Tampere, Finland. After 1 year of lower limb strength
training the subject injured a knee ligament and had to undergo 1 year
rehabilitation. The study found that physical training has the potential
to increase the mass of healthy bones. In contrast immobilisation, used
as a treatment of soft tissue and bone injuries is shown to result in
atrophy of these tissues.
Next comes a study of the effects of resistance training on prepubescent
children. For 12 weeks 52 children were given the training which consisted
of maximum sustained isometric contraction of elbow flexion for ten
seconds. A control group of 47 children did not receive the training.
Both groups after the 12 weeks showed increases in the cross sectional
areas of tissue in the upper arm, however, in the control group this
was because of an increase in fat area, while in the training group
it was due to increases in muscle and bone area.
Finally an American review found that part of the reduction in bone
density observed in older people is due to disuse rather than the aging
process itself and that older people who have been active for many years
seem to exhibit generally enhanced bone density.
Let's look now at specific Tai Chi based studies. The Department of
Physical Medicine and Rehabilitation at the National Taiwan University
Hospital treated a group of 41 males and females aged from 50 to 64
years and a control group of 49 sedentary males and females. Tests found
that the oxygen uptake, O2 pulse and work rate of the Tai Chi group
were significantly higher than those of the control group.
An interesting study at the University of Connecticut, School of Medicine
found that in a study of women aged 62-75 years, those who did only
posture control exercises, including some simple Tai Chi exercises showed
no significant difference in improved posture compared with a control
group who did these exercises and some flexibility training as well.
(i.e. as much benefit from Tai Chi alone in terms of improved posture
as from Tai Chi plus flexibility training).
The Department of Health Sports and Leisure Studies at the Northeastern
University in Boston compared the metabolic and cardio-respiratory responses
to the continuous performance of Wing Chun and Tai Chi Chuan exercise.
The study found that the ventilatory equivalent for for oxygen obtained
during Tai Chi Chuan exercise was significantly lower than for Wing
Chun exercise, suggesting that "Tai Chi practitioners utilise efficient
breathing patterns during exercise". However, the study also found
that only the continuous performance of Wing Chun exercise elicited
values for oxygen uptake and heart rate responses that would be expected
to bring about a cardiorespiratory training effect in subjects with
with a relatively low initial value of oxygen uptake.
One of the problems with the last study is what do we mean by continuous
practice of Wing Chun and Tai Chi Chuan exercise ? Both these arts have
hard and soft elements there are many different approaches in both arts.
For example typical Cheng Man-ching hand form is very understated while
other styles like my own tend to be somewhat more vigorous and expansive.
The vigorous and continuous practice of Tai Chi spear or Tai Chi throwing
techniques would definitely cause a cardiorespiratory training effect.
So next time you feel below par, forget the Prozac, get yourself some
Tai Chi Chuan training.
