Purpose. The purpose of this study was to investigate and compare the effects of plyometric and weight (isotonic) training on lower extremity electromyography in physical education students. Basic procedures. In this study, 45 students from the physical education and sport sciences faculty of Shahid Chamran University were selected and divided in 3 groups (plyometric - 15, weight - 15, control - 15). Two experimental groups participated in a 6 week and a 3 week period sessions. The electrical changes of muscles were measured using sergeant test for explosive power and squat test for absolute power. Main findings. The data was collected via MT8 and analyzed using MBM. The results of the variance analysis test (ANOVA) were compared with the average values of electromyography changes (explosive and absolute power) and it was shown that electrical changes (explosive and absolute power) of biceps femoris muscle in all groups were non-significant whereas electrical changes (explosive and absolute power) of rectus femoris and gastrocenimus muscles were significant.
