The Relationship between Jump Ability and Athletic Performance in Athletic Throwers

The purpose of this study was to examine the relationship between jump ability and athletic performance of athletic throwers based on data taken over two years. The data of 24 1st-year and 2nd-year male university throwers was compiled to examine the relationship regarding athletic performance. In summary, the three events of standing long jump (SLJ), squat jump (SJ), and counter-movement jump (CMJ) were always in a positive correlation with athletic performance in the two-year measurement. Next, SJ was most relevant to the athletic performance of the five jump measurement items. Standing triple jump (STJ) and rebound jump (RJ) did not improve in two years, and no association with the athletic performance was seen. These results suggest that simple explosive exercises, such as SLJ, SJ, and CMJ, are effective for evaluating the physical fitness of throwers. The vertical jump capability is particularly useful for evaluating athletic performance. The innovation of this study is found in SJ, which exerts power from a stationary state, and could be significant in optimizing athletic performance, which can be enhanced through modified training practices that incorporate SJ.
