The Effects of Three Different Squat Exercises on iEMG, MEF of Rectus femoris, Biceps femoris and Gastrocnemius
[PURPOSE] The purpose of this study was to evaluate the effects of different squat exercises on iEMG and MEF on Rectus femoris, biceps femoris and gastrocnemius. [METHODS] In this study, 12 male college students who had more than two years of weight trainingexperience were recruited, and conducted3 sets of three different squat exercises (isometric, isotonic, and jump squats) with 60 seconds rest between sets. The iEMG and MEF were analyzed on three different muscles during these exercises(Rectus femoris, biceps femoris, and gastrocnemius). Two way repeated ANOVA was used to find out statistical significance at the level of alpha = .05. [RESULTS] Rectus femoris'siEMG during isotonic and jump squats was greater than that of isometric squat (p<.01, p<.001). iEMG on biceps femoris when performing isotonic and jump squats was significant different from that of isometric squat (p<.01, p<.001). iEMG on gastrocnemius was the highest during jump squat and that of isotonic squat was the second highest, and so on (p<.001). As sets in squat exercises proceeded, iEMG of gastrocnemius during isotonic and jump squats decreased (p<.001). The MEF of bicepsfemoris during isometric squat was the highest and that of jump squat was the second highest. MEF of gastrocnemius during isometric squat was greater than isotonic and jump squats (p<.001). As sets proceeded, MEF of gastrocnemius was increasedduring isotonic and jump squats(p<.001). [CONCLUSIONS] As a result, it is concluded that iEMG during isotonic and jump squats was greater and MEF during isometric squat was higher than the other exercise types, and iEMG during isotonic and jump squats tended to be lower as MEF increased.
