THE RELATIONSHIP OF THE NUMBER OF PITCHES TO THE KINETIC CHANGES OF BASEBALL PITCHING

Abstract

INTRODUCTION: At the latter half of the baseball game, ball velocity and control decrease due to fatigue by excess of pitching. Therefore, it is difficult for a baseball pitcher to pitch the whole game in many cases. Although many studies have been reported about the kinematics and kinetics of baseball pitching, only a few trials were analyzed for one subject. The purpose of this study was to investigate the relationship of the number of pitches to the kinetics changes of pitching during a simulated baseball game.
