Tai
Chi, Balance, and Longevity

Tai Chi gained legitimacy in the medical community when it
was shown to be an effective means of fall prevention in the
elderly. Falls often result in permanent disability and shortened
life spans. Tai Chi proved to be an effective, low cost method
of improving balance.
Fong
Ha, a respected Tai Chi/Yiquan practitioner gave me additional
insights concerning balance and longevity at one of his recent
workshops. He mentioned that the Chinese believe that good
balance is a major factor in promoting longevity. Sifu Fong
was not emphasizing fall prevention.
The
characteristic gait and posture of many senior citizens can
give important lessons about balance and the bodyÕs mechanism
of maintaining equilibrium. Two distinct "abnormalities" are
present; a hunched (kyphotic) trunk, and a stiff, shuffling
stride. These abnormalities are, in fact, adaptations to insure
safety.
We
are genetically programmed for survival. A good example of
this is the fractured wrist that often occurs as the result
of a fall. The arms automatically thrust outward as balance
is lost, in order to prevent serious bodily injury, especially
to the skull. This reaction does not require conscious thought,
it is totally involuntary.
The
elderly, "abnormal" gait is most often the response to impaired
balance. The hunched over trunk aids in keeping the gaze on
the ground and feet. The eyes have to assume a greater role
in orientation because of an increasing impaired internal
(proprioceptive) sense of balance. The same mechanism occurs
in younger individuals when descending stairs. The gaze automatically
shifts downward to keep the feet and steps in sight, especially
if there is no hand rail.
The
stiff, shuffling stride minimizes time spent on one leg while
the other leg is airborne (swing through). A longer stride
presents greater instability. The balance impaired individual
needs to spend as much time as possible with both feet on
the ground. 
It
is important to reemphasize that these adaptations occur without
conscious planning. They develop in response to a perceived
internal threat to safety. There is a price to pay, however.
This gait pattern requires greater energy expenditure. Walking
becomes burdensome. Effortlessness is replaced by constraint.
Movement becomes redesigned to keep a tight rein on the center
of gravity.
This
change in mobility often causes a more sedentary life style,
with an inevitable downward functional spiral. Mental acuity
can suffer. Fear of movement is a powerful deterrent to curiosity
and inquisitiveness, thereby limiting the desire for social
interaction. Studies of healthy, aged individuals have shown
that it is these traits that are largely responsible for their
longevity.
Tai
Chi is about balance. Yang Cheng FuÕs exhortations to maintain
an erect spine and to keep the head suspended serve to keep
the practitionerÕs gaze off the ground, thereby heightening
the proprioceptive sense of balance. Tai ChiÕs signature,
slow movement, sharpens and challenges balance by prolonging
the transition time from single to double weighted postures.
The effortless power that skillful players display stems from
superior balance.
Perhaps
it would make better sense to adopt a health regimen that
incorporated Tai Chi, rather than undertaking the Western
"no painÑno gain" approach which is often more concerned with
appearance rather than function. The latter may provide more
immediate short term benefits, but is often injurious and
impractical to maintain over a prolonged period. Tai Chi,
with its decided emphasis on balance is ideally designed for
the long run.
