The purpose of this study was to examine the effect of plyometric training and weight training on leg explosive power among men javelin throwers. Sixty intercollegiate-level throwers aged 19-22 years were randomly assigned to three groups of twenty: Experimental Group I (plyometric training), Experimental Group II (weight training), and a control group. The experimental groups underwent a 12-week training program, while the control group received no special training. Leg explosive power was assessed using the vertical jump test in pre- and post-test conditions, and the data were analyzed using ANCOVA at the 0.05 significance level. Results revealed that the pre-test means of plyometric (58.30), weight training (59.13), and control groups (57.63) did not differ significantly (F = 0.54 < 3.10). However, post-test means showed significant improvements in the plyometric (67.63) and weight training (63.30) groups compared to control (58.37), with an obtained F value of 14.57 > 3.10. Adjusted post-test means confirmed significant differences (plyometric = 67.68, weight training = 62.71, control = 58.92; F = 21.76 > 3.10). Post hoc analysis using Scheffe's test indicated that plyometric training was significantly superior to weight training (MD = 4.97) and the control group (MD = 8.76), while weight training was also significantly better than control (MD = 3.79). These findings demonstrate that both plyometric and weight training significantly improve leg explosive power in men javelin throwers, with plyometric training proving to be the most effective.
