The objective of the study was to observe the difference of moving function of lower-limb in relation to the length & silouette of tight skirt. Four types of tight skirts (2 lengths×2 silhouettes) were made for the experiment. The surface E.M.G in four different locations of leg muscles (Rectus femoris, Semitendinosus, Tibalis anterior, Gastrocnemius) were recorded. The sensory test to decide how to be fatigued after longtime wearing of skirt were examined two times per a day. The fatigue sensory test was scored a Likert-type scale (1= no fatigue, 5=heavy fatigue). Data were analyzed by the repeated ANOVA and Duncan`s multiple range test with use of SAS Package. The main results of this study were as follows: 1. As a result of analysis of E.M.G., in case of walking on the floor there was significant difference in the moving function according to length of skirt and in case of stepping there was significant differnce in three ways (length - silhouette, length, silhouette). 2. From the record of walking the step-length, stride-length, step-width were found affected by garments, but foot-angle was not affected. The moving function of slim type was lower than that of semi type and that of ankle-length skirt was lower than that of knee-length skirt. 3. The results of the sensory test agreed with that of E.M.G and Footprints.
