The Effect of Plyometric Training on the Power of Lower Leg s Knee and Ankle Joint

The purpose of this study was to investigate effect of Plyometric Training and Isotonic Training on the Power of Lower Leg`s Knee and Ankle Joint. Subject were 21 K-university male students who had been trained for 8 weeks with Plyometric, Isotonic, control and divided into 3 groups randomly : Plyometric training group, Isotonic training group, control group. Plyometric Training Program was consists of 7 style method (Pike Jump, Double leg hop, Double leg bound, Single leg hop, Stride jump cross over, Alternate leg bound, Box jump). Plyometric Training Program performed the two days a week and period of 8weeks. Isotonic Training Program was consists of 5 style method(leg extension, leg flextion, leg press, heel raise, half squat). Isotonic Training Program performed the two days a week and period of 8weeks. Control was consist of daily routine, also control`s period is 8weeks. Data were obtained from pre-test(before treatment), mid-test(after 4weeks-treatment), post-test(after 8weeks-treatment). The collect data were analyzed by One Way ANOVA. A significant level was .05. Result were as follows: 1. Plyometric Training Group was not a significant effect on the Power of lower leg`s knee and ankle`s extensor and flexor. 2. Weight Training Group was not a significant effect on the Power of lower leg`s knee and ankle joint extensor and flexor. 3. Control Group was not a significant effect on the Power of lower leg`s knee and ankle joint extensor and flexor. 4. Ability of Jump was a significant effect on increasing between isotonic training group and control group at post-test. From the above results, for the purpose of investigation the effect of Plyometric Training on the Power of Lower Leg`s Knee and Ankle joint, the data of the study showed that (1) Plyometric Training group, Isotonic Training group and Control group were not a significant effects on the Power of lower leg`s Knee and Ankle joint. (2)but Ability of Jump were a significant effects on between Isotonic group and Control group at post-test.
