摘要：The purpose of this study was to analyze the significant relationship between body mass index on the speed of punching Gyaku-Tsuki,to analyze the significant relationship between leg muscle strength to the speed of punching Gyaku-Tsuki,and to analyze the significant relationship between arm muscle strength to the speed of punching Gyaku-Tsuki.This research is non-experimental quantitative research.The research design used is a correlation design.In this study,researchers used total sampling.The variable is divided into two independent variables,body mass index,leg muscle strength,and arm muscle strength.While the dependent variable is the speed of punching Gyaku-Tsuki.Techniques data collection uses tests and measurements.Data analysis used simple regression and multiple regression.The results of this study indicate that body mass index only contributes 2.8%,leg muscle strength is only 4%,arm muscle strength is only 2.9%,and body mass index,leg muscle strength,and arm muscle strength only 4.8%.The conclusions of this study are body mass index factor,leg muscle strength,arm muscle strength does not have a significant relationship to the speed of punching Gyaku-Tsuki either alone or together.
