Balance

For the past decade, I have been involved with the training routines of the elderly, currently have seven clients that range in age from 85-95. And while it differs greatly from the training of world-class athletes, there is a degree of satisfaction that is no less meaningful. The elderly have reduced egos, few specific training goals and are more appreciative. If they can return for the next workout and maintain mobility, they are grateful - which does not diminish my efforts. As a trainer, however, I am bombarded with the challenge of "I need to improve balance" - a common request of all trainers. So, as good Samaritans, we run our elderly clients through a series of balance activities that are supposed to improve balance for daily living. I was never comfortable with the scenario.

First, I was not schooled in balance activities and felt inadequate despite devouring several books full of 'balance-improving' activities.

Second, I was not convinced that improving balance at specific tasks had any positive transfer to other activities, such as the daily-living ones we were trying to improve. So I read, and read.

Brian Johnston put it together nicely in his book Systems Analysis, in which he critiques various forms of popular exercise, including "functional" training. Johnston classifies balance as an innate ability, not subject to change. You have it or you don't. The improvement in the performance of skills specific to balance (those generally administered by trainers) were just that - skill improvement through practice. Balance improvement occurred specifically to that skill, with no transfer to other non-specific skills . "Other" skills were different - almost the same, similar to - but they had their own set of specifics, their own input of balance, an input different to that practiced in the gym.

Aside from making the elderly feel better about their balance (a psychological factor) and the effort made to improve balance by trainers, the fact remains: Balance cannot be improved as an ability. It can only be improved specific to a skill.

With apologies to the elderly, balance is innate.

How We Learn

Somebody once asked Ben Hogan for a golf lesson. His reply, "You can't teach golf. You can only learn it." Hogan wasn't arrogant, just giving an honest opinion. To learn golf, you must practice until an efficient and effective motion is ingrained in the nervous system and the muscles they feed. Timing, control, balance, feel, rhythm - the muscles and nervous system must figure things out. It must be precise, specific, exactly the same - swing after swing - to reach the pinnacle. Things almost correct will likely retard the process, insert roadblocks, promote negative results.

Yet, this insertion is exactly the essence of sport-specific or performance training. Do something (an exercise or movement) that resembles a sport-movement pattern; then assume there is a positive transfer to the sport itself. Poor assumption. The motor learning principle of specificity is violated every time - something coaches and trainers don't get. They continue to train athletes under false assumptions and beliefs, then argue that they produce results. They have the studs in the barn to prove it. Doing something will produce a result, not the best result, a result.

Why do coaches and trainers not get it? Your guess is as good as mine, but one thing is certain. The alternative, old-school thought, is unattractive, not hip, not functional. Strengthen the muscles needed in the sport, independent of 'how' they are to be used. Then, take the new muscles out to the ball game. Let the nervous system piece the new structure and strength together in the only way possible - by practice of the sport itself, specifically, with no added weight or opinion. Practice the sport exactly as you would in competition.

Let's put the current sport-specific training approach where it belongs - the nearest trash can. The nervous system is capable of improvement with the proper signals - signals not confused by extra weights that trigger patterns similar to, but not exactly like, that encountered in the sport.

Strengthen muscles; practice the sport. Anything else is insanity, fraud or both.

Get it?
