Special Report ;-) IT'S GREAT NEWS for couch potatoes everywhere. And it's official. Scientists have discovered that simply imagining exercising can significantly increase muscle strength. Apparently ten volunteers who took part in mental work outs five times a week, imagining lifting heavy weights with their arms, increased their bicep strength by 13.5 percent on average. Not only that, the gain in strength lasted for three months after they stopped the mental exercise regime. The study was conducted by Guang Yue, an exercise psychologist at the Cleveland Clinic Foundation in Ohio. He believes his discovery could help patients too weak to exercise to start recuperating from stroke or other injuries. It could also help older people maintain strength. It sounds incredible that just thinking can have such an effect - so how does it work?
Dr Yue said mentally envisaging exercise increased the strength of the command signal sent by the brain to the appropriate muscle. Muscles are prompted to move by impulses from nearby motor neurons, and the firing of those nerve fibers depends on the strength of electrical impulses sent by the brain. "This suggests you can increase muscle strength solely by sending a larger signal to motor neurons from the brain," said Dr Yue. Martial Arts
"To enhance the effects of the exercises, focus on the part of the body for which the exercise is intended," advises Wong. "When you are doing curls, for example, concentrate on the muscles of your wrists, forearms, biceps and shoulders. Visualize them working and growing stronger." The mental approach recommended by Wong isn't new. It dates back hundreds, if not thousands of years. Sceptics, however, have often dismissed this aspect of Oriental martial arts - but Dr Yue's study could well give it scientific credence.
