Abstract
The purpose of this study is to evluate the effect of modeling in training to keep muscles tense and loose. Nine male and forty female subjects were trained with the technique of relaxation of slanting up one arm, while relaxing the elblow of JICO SHIKAN-HO by K. Harano (1977). The effect of modeling was found in the appearance behavior and EMG of physiological responses. The main results were as follows : Modeling was effective for learning the appearance behavior. However learning to keep muscles tense and loose could not found by EMG. Adding learning to keep muscles tense were more easier than keeping muscles loose. There existed significant defferent parts in learning to keep muscles tense and loose.
