다국어 초록 (Multilingual Abstract)

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.
