플라이오메트릭 트레이닝이 순발력 향상에 미치는 효과에 대한 메타분석

Abstract

In this study, the purpose of this study was to select a leading study that conducted only plyometric training for 10 years in domestic research to see if it affects the explosive muscular strength of the lower extremity and to see if there are any differences in effectiveness depending on the intervention period. <BR> After applying plyometric training, the results of the effect size test of the fast-acting element showed that the interstudy heterogeneity was high (I²=73%, p=.001). The effect size is .69 (95%CI=.05, 1.32) with a significant effect (Z=2.12, p<.05) The shown plyometric training has had a significant effect on improving explosive muscular strength. The effect sizes according to the duration of exercise showed small and large effect sizes at 8 and 12 weeks, but no significant effects. However, at week 10, there was a significant effect along with a large effect size. As a result of the effect size according to the number of ground contacts, there was no significant effect in steps 1 and 3, but there was a significant effect in step 2.<BR> The following conclusions were obtained from the review of this study. Plyometric training is effective in improving the explosive muscular strength factor, and in the exercise period, it can be said that it has a great effect in the mesocycle of the training period (3 to 4 months).<BR> The intensity of exercise can be seen to have a great effect when the number of contacts is not more than 150 to 300 times.
