By this immobile contraction, its adherents claim, nearly 100% of the muscle’s thousands of hair like fibers are stimulatedas compared with the mere 50% to 60% involved in isotonic exercise.Īthletes use a variety of bars, braces and frames that can be adjusted to just the right inch or angle to strengthen a muscle.įor a particular job (one high jumper successfully trained by straining against a device that held his take-off leg at the exact angle from which it started its spring). Isometric exercise, on the other hand, does not move the muscle at all the exercises are all performed against an immovable object. Traditional exercise, known as “isotonic,” beefs up a muscle by moving it. But it was not until 1953 that two German doctors worked out the implications of this experiment and applied them to the human body. Scientists found that when one leg of a frog was tied down over a period of time, it grew significantly stronger than the leg left free. The basic principle of isometric exercise was discovered back in the ’20s. Instead, they are practicing the very latest wrinkle in body culture: isometrics. These are not the victims of some new virus, nor has the strain of modern living sent them around the bend.
