THE INFLUENCE OF THE PRACTICE METHOD ANDSPEED ONDWI CHAGIEXPLOSIVE POWER

The purposesof this study are(1) to reveal the difference in the effectsof the practice method and speed on the explosive powerofdwi chagi kick; (2) to describe the interaction between the practice method and speed and the explosive powerofdwi chagi kick; (3) to reveal the difference in the effectsof the practice methodand speed of the explosive power of dwi chagi kick for athletes who have high speed; (4) to reveal the difference in the effect of the practice method and the speed on the explosive power chagi bi-kick for athletes who have low speed. The method used in this research was experiment with a 2x2 factorial design. The data were analysedusing Anova and Tukeyat the 5% significance level. The results can be explained as follows,(1) Overall, there is a difference between the effect of circuit and that of interval training method on the explosive power of dwi chagi kick; (2) There is interaction between the practicemethod, the speed and the explosive power of dwi chagi kick; (3) for athletes with high speed,Circuit training method has higher impacton the explosive power than interval method;(4) athletes who have low speed, the method of interval training hashigher impact on the explosive power than circuit method.
