The purpose of this study was to find out the effect on the lower limb muscle activity by differentiating the width of the stand and the height with using wooden plate during Smith machine squat exercise. In this study, 20 female college students were collected as participants. The width of the standing position was determined from participants by measuring a width of the shoulder, and the squat motion was measured based on 0%, 75%, and 140% of the shoulder width. In addition, the height of the wooden p lates were 0 cm, 3cm, and 6cm. EMG was a ttached to measure the r ight E rector Spinae, Rectus Femoris, Vastus Medialis, Vastus Laterlis, Biceps Femoris, Medial Gastrocnemius, and Tibialis Anterior. The mean(M) and standard deviation(SD) of all measurements were calculated, and one-way ANOVA was used to find significant difference between groups. The post-hoc verification was done using Duncan’s method.
The result showed that, first, squat motion based on width of the standing position did not showed a significant difference in other areas, but Vastus Medialis showed significant difference (both decreasing (p<.05) and increasing (p<.05)). Second, squat motion using wooden plates did not showed a significant difference in other areas, but Tibialis Anterior showed a significant difference (both decreasing (p<.05) and increasing (p<.01)). By analyzing the same results, the study suggests that applying different squats by performing appropriate movements to partially enhancing the muscle rather than targeting entire femoral squat movement. It also suggests that, it would be safe and accurate followed by appropriate posture during machine training and free-training.
