The Truth on Fitness


The Cybex Research Institute, under the guidance of Dr. Paul Juris, has the directive of discovering the scientific truths that verify the information disseminated to the fitness community and the products engineered by Cybex International. In this section, "The Truth on Fitness", the Institute will examine a variety of pertinent fitness topics, and present credible basic science and evidence-based conclusions that will help our readers make smart decisions about their own fitness methods and practices.

The Truth on Fitness: Balance and the Center of Gravity

In all of our movement actions, there is to some degree, a need to maintain our balance if we are to successfully complete a task. Dr. Paul Juris examines the biomechanics of balance, different types of balance conditions, its control systems, and the various training methods that contribute to improving balance.

The Truth on Fitness: Keeping your Balance – Standing or Moving

Stability has both advantages and disadvantages, depending upon the functional goal. If the objective were to remain stationary, for example, a high degree of stability would be advantageous. On the other hand, if one wanted to move quickly from one position to another, too much stability would hinder displacement, and would be a disadvantage. Often, finding just the right amount of stability is essential to successful function.

The Truth on Fitness: A Sense of Balance

Whether equilibrium arises from subtle control of the center of gravity, or a dynamic repositioning of the base of support in front of a moving center of gravity, the eventual outcome is the product of information gathering and the ensuing motor response. To put it plainly, one must first recognize that their stability is being, or is about to be challenged, and then, they have to produce some action intended to maintain equilibrium. Through a combination of complex information from our eyes, muscles, joints, ears, and other tissues, balance and equilibrium can be maintained or lost. In this installment, we'll explore the sensory side of this equation.

The Truth on Fitness: Developing Better Balance

When one thinks of balance training, one may first envision someone standing on a wobbling disk or air-filled rubber pillow, because these techniques have become vogue in current fitness practices. These moving and distorting objects are referred to, by researchers, as labile surfaces. In fact, it is a rare occasion indeed when one can walk into any gym and not see someone exercising atop a labile device. The question that you might ask yourself is, "do I really need to stand on one of those things in order to improve my balance?" Well, maybe, but before we answer that, we should first understand how balance is controlled. Dr. Paul Juris describes the best approach to improve balance and stability during motion activities.
