Abstract
Fastpitch softball has undergone a relative resurgence in popularity in the NCAA in recent years as marked by a greater than two fold increase in participating teams and athletes. This trend has coincided with rises in NCAA employment of strength and conditioning professionals as well as attention paid to the generation of maximal bat velocity. The development of bat velocity positively affects the hitter's decision-making time, ability to make solid contact with the ball, increase hit distance and velocity. Thus, the purpose of this study was to determine if there were significant correlations between lower extremity power, upper extremity power and kinetic chain efficiency and linear bat velocity in NCAA Division II softball players. Performance testing was conducted on subjects utilizing the seated medicine ball shot put, medicine ball hitter's throw and countermovement jump in combination with bat swings. Maximal velocity of the bat's sweet spot was measured using a 7-camera motion analysis system. Bivariate correlations and linear regressions were applied to determine relationships between the performance variables and bat velocity. The most correlated performance-related variable was the seated medicine ball shot put (r=0.312, p < 0.05), which contributed to 6.6% of variance between subjects.
