Abstract
Purpose of this study was to measure muscle activity in different weights and positions when performing squat exercise in High bar squat, Front Squat, or Low bar squat positions to provide more efficient squat position for lower limb muscle strength. Subjects for this study were 19 healthy males with age ranging from 20 to 30 and majoring in physical education. Measurements were taken in low-weight (1RM 50%) and high-weight (1RM 80%), which is based on 1-RM measured in advance, in random orders of High bar squat, Front Squat, and Low bar. Subjects performed eccentric workout for 3 seconds and concentric workout for 3 second and was comparatively measured of their muscle activity of gluteus maximus muscle, gluteus medius muscle, rectus femoris muscle, vastus medialis muscle, vastus lateralis muscle, biceps femoris muscle, tibialis anterior muscle, and gastrocnemius muscle. The result showed high muscle activity in all muscles except vastus medialis muscle. in eccentric workout (P˂.05). Based on the results, in squat exercise for strengthening of lower limb muscle, one must choose appropriate high-weight for oneself and when performing squat for purpose of developing gluteus maximus muscle. and biceps femoris muscle. low bar squat is recommended while front squat is recommended when performing squat for purpose of developing rectus femoris muscle. and tibialis anterior muscle.
