The purpose of this study was to clarify the relationship between sprinting ability and ball speed incollege baseball pitchers, and to examine the evaluation method of sprinting ability considering bodyweight and lean body mass. Thirty-one college baseball pitchers participated in this study. Height,weight, lean body mass, body fat mass, muscle mass, and skeletal muscle mass were measured, andbody fat percentage, body mass index (BMI), and skeletal muscle index (SMI) were calculated. Ball speedwas measured using Rapsodo pitching 2.0. The baseball pitcher was asked to throw 10 full pitches fromthe pitcher's mound toward the catcher. Maximum ball speed was used as an index of ball speed. Toevaluate sprint ability, sprint times of 10m, 30m, 50m, 100m, 200m, and 400m were measured, andrunning speed, momentum, and kinetic energy were calculated. Pearson's product-moment correlationcoefficient was calculated to investigate the relationship between the measured indices. Ball speed wassignificantly correlated with body weight, BMI, lean body mass, muscle mass, and SMI. In addition,ball speed showed a significant negative correlation with running speed in 200m and 400m sprints, and showed a significant positive correlation with momentum and kinetic energy in 10m, 30m, 50m,and 100m sprints. The results of this study suggest the importance of considering body weight whenevaluating the sprinting ability of baseball pitchers.
