The effectiveness of lateral box shuffle plyometric exercise on increasing limb muscle power of badminton athletes

Introduction: The problem in this study is the low muscle power ability of badminton athletes. Objective: This study aims to determine: 1) the effect of pliyometric lateral box shuffle training on increasing leg muscle power of badminton athletes. 2) the difference in the effect of pliyometric lateral box shuffle training between the treatment group and the control group on increasing leg muscle power. Methodology: This type of research is an experiment with pre test and post test control group design. The sample in this study amounted to 78 athletes who were taken using random sampling technique. The subjects were divided into 2 groups, namely the treated group of 44 athletes and the control group of 36 athletes. The instrument used is to measure leg power, namely the vertical jump test. The data analysis technique used is the independent sample t test and continued with the paired sample t-test. Results: The results showed that: 1) There is a significant effect of lateral box shuffle training on increasing leg muscle power with a significance value smaller than 0.05 (p<0.05). 2) There is a significant difference in influence between the group given treatment and the control group on increasing leg muscle power, as evidenced by the mean value of leg muscle power in the treatment group of 95.71 kg m/s while the mean value of leg muscle power in the control group is 78.93 with an average difference in post test of 16.78 kg m/s. Conclusions: The group that was given the treatment had better leg muscle power compared to the control group that did not receive treatment.
