Correlation Between Body Composition and Power Performance in Beach Volleyball Athletes

Abstract

Beach volleyball players need to have a good explosive power performance between the lower limbs and upper extremities as support in jumping and smash-hitting techniques. The purpose of this study was to analyze the correlation between body composition on explosive power of lower limbs and upper extremities in beach volleyball athletes. This research is correlational research with a descriptive correlation method. The samples used were beach volleyball athletes who underwent training camps ahead of the Indonesia National Games. A total of 8 athletes participated in this study. Body composition data that has been taken is the percentage of body fat, muscle mass, and body mass index while for power performance, it is vertical jump and seated medicine ball. The non-parametric test of data analysis through Spearman's rank correlation was used to analyze the relationship between variables. The results showed that there was a correlation between body fat and vertical jump (p<0.05). In addition, related results were also shown in muscle mass and arm power (p<0.05) and body mass index and arm power (p<0.05). This study shows that there is a significant relationship between body composition on the explosive power of lower limb muscles and upper extremities in beach volleyball athletes.
