Gender difference in lower limb muscle activity during landing and rapid change of direction

Surface electromyography (EMG) of the rectus femoris, biceps femoris and gluteus maximus were recorded for 10 male and 10 female basketball, volleyball or netball players performing five repetitions each of two tasks; (1) landing from a maximal height vertical jump and, (2) 45° rapid change of direction on their dominant leg. Independent sample t-tests were conducted to determine sex differences and paired samples t-tests were conducted to determine task differences in peak EMG muscle activity
