It is highly significant for athletes to keep their athletes capabilities from deteriorating by lessening stain and fatigue of their muscles. This is why various corporations have recently been concentrating positively on developing sports-pants with emphasis on supporting leg muscles. In autumn 2003 a company D developed power-pants with auxiliary tape. The auxiliary tape supports the adductorious and the gluteus medium etc., and by doing so it helps the body maintain muscular balance of inner and outer side of thigh. Thus it provides maximum support to the muscles with minimum effort by athletes. The front tape especially helps athletes preserve their proper forms by letting them become aware of loosening muscles and widening knee position caused by fatigue. This research explores the effectiveness of auxiliary tape in Power-Pants. As a method of the study, 20 women in their 20s were selected to wear five different experimental clothes and a sensory test was conducted as to their feelings to wear the test clothes both in motion and at standstill. As a result, auxiliary tape in Power-Pants (after modification) was found to be effective in supporting the athletes' inner muscle when moving.
