COMPARISON OF THE EMG ACTIVITY BETWEEN PASSIVE REPEATED PLYOMETRIC HALF SQUAT AND TRADITIONAL ISOTONIC HAFT SQUAT

Abstract

The purpose of this study was to investigate neuromuscular characteristics of different method of strength training in lower extremity. Three healthy college males were the subjects in this experiment, the subjects’ mean (±SD) age, height, and weight were 25±4.5 years, 172.33±15 cm, and 67.66±11.5 kg, respectively. All subjects attempt to perform Passive Repeated Plyometric half squat movement and traditional isotonic half squat movement. The results revealed that the IEMG of half squat performance by Passive Repeated Plyometric Training Machine in 60R.P.M. was significantly higher than traditional isotonic half squat performance in same speed. The findings of this study suggested that the Passive Repeated Plyometirc Training of lower extremity can significantly increase muscle strength and power than traditional training method.
