|What is "dynamic balance"?
Movement nd change, with everchanging harmonious proportions between stability and mobility.
From a paper titled:
BIOMECHANICS OF BALANCE: PARADIGMS AND PROCEDURES
Jackie L. Hudson
California State University, Chico, CA, USA
"Balance, like coordination, is understood by virtually everyone to be a critical component of skillful movement."
"Another, newer, definition of balance is
harmonious proportions. In this sense a balanced diet would have harmonious rather than equal proportions of carbohydrate, protein, and fat. The predicament for biomechanists is to determine specifically what aspects of balance should be in
either equal or harmonious proportions."
"But, as Kreighbaum and Barthels (1990, p.
310) point out, true equilibrium in human activities is practically nonexistent because "the body is always experiencing some kind of movement change." Greenlee (1981), in a qualitative text, uses the terms harmony, loss of balance, and
"In sum, balance is defined here as the harmonious and contextually appropriate interplay of stability and mobility of the body with respect to its BoS. Presumably, less skillful performers and less successful performances are characterized (in many cases) by less harmonious or less appropriate control of
stability and mobility."
It is a short paper, and a worthwhile read.
Personally I like the concept of "harmonious proportions" and dynamic balance, rather than equilibrium, because it allows us to go beyond static and equal into the real world of movement and change serving our intent as we maintain an upright body position. Like everyone has noted, equal doesn't exist when we have movement and change, but we can have stability and mobility existing in harmonious but unequal proportions, serving our behavior goals. The tai chi symbol represents this concept of harmonious proportions very well. And just like in the tai chi symbol, in effective skiing we always have a little mobility left in our stability, and a little stability left in our mobility. Otherwise we would fall, or stop moving.
