Isometrics is often called Static Contraction now days.
In the 1920’s scientists stumbled across scientific proof that isometrics really worked.
Scientists at Springfield College in Springfield Massachusetts ran an experiment where they took a number of frogs and tied up one of their legs, completely immobilizing it. The frog could only move one leg free, and couldn’t move the other one at all. They wanted to see the effects of atrophy on the bound leg.
Surprisingly, after two weeks, the bound legs had grown stronger and larger. So much so that the frogs now actually jumped in a lopsided fashion.
The researchers had actually made an incredible discovery concerning isometric training, but they simply didn’t realize it. Apparently, by binding the leg, the frogs had to use all of their muscles right down to their deepest fibers to try to move their leg. In contrast, it only took a small percentage of the frog’s muscle fibers to move the free leg.
Although isometric exercises don’t typically have a large range of motion, when the muscle is exerted continuously and vigorously, it will grow stronger and larger than doing a fluid, repetitive motion that relies on momentum (imagine a bicep curl done while swinging the dumbbell up and down). Strength and mass is achieved by working the muscles intensely and deeply.
- I would read that information and look at the pictures with amazement. That was really my start in wellness and health. That was over 55 years ago on a small farm about 50 miles north Pittsburgh, Pennsylvania called Mercer.
The basic idea was to put 100% effort into an exercise without movement for about 10 seconds every day. An example would be to try to pick up a car with 100% effort. That would be like doing a dead lift with weights only there would be no movement. The new research science proves we only need to do it once a week (not every day). http://www.youtube.com/watch?v=4_OJdeWacFo
Alex Goldman took my word for it and did the dynamic tension for several years. You can see by this picture it worked.
