The purpose of this study was design to observe the switching mechanism of leg muscles for 15 males and 15 females aged from 18 to 22 years. The subjects were measured physique (body height, body weight, length of lower extremity, % fat), muscular output (isometric leg strength, vertical jump) and agilily ability (foot tapping, stepping, side jumps). The EMG activities of gastrocnemius and tibialis anterior were recorded by bipolar surface electrodes. The following results were obtained from this experiment. 1) No significant sex difference was found on each agility ability. 2) Negative significant corelation was found between stepping frequency and % fat. 3) Phasic discharge period and silent period of leg muscles prolonged in order of foot tapping, stepping and side jumps. 4) Positive significant corelation was found between foot tapping 3nd stepping, and corelation between stepping (standing) and side jumps was positively significant. 5) Frequency of repeating movement dropped in the end period of measurement.
