Abstract

This study aims to determine the effect of plyometric and flexibility training methods to improve the momtong dollyo chagi kick technique in taekwondo athletes. The effect of training programs that combine physical conditions specifically has no results stating that they are interrelated to improve taekwondo kick techniques. The research method used is experimental treatment by level 2 x 2. The results of this study: firstly, there are differences in the leg power of momtong dollyo chagi kicks for taekwondo athletes in the plyometric standing jump and box drill training methods with the results Fo (A) = 12,111 > F-table 4,11. Interaction Fo (AB) = 14,044 > F-table = 4,11 with the percentage effect of plyometric and flexibility exercises of 33.83%. Plyometric standing jump exercise is better for increasing leg power of momtong dollyo chagi kick than box drill exercise for athletes who have high flexibility with t₀ 16,496 >t_{table(0,05:10)} 1,688. Box drill exercises are better for increasing the leg power of momtong dollyo chagi kicks than standing jump plyometric exercises for athletes who have low flexibility with a value of t₀ 2,455 > t_{table(0,05:10)} 1,688. Thus, it can be concluded that both standing jump plyometric exercises and box drill combined with flexibility can have the effect of increasing leg power, so that the trainer can choose a power and strength training program through plyometric training to prepare for the competition.
