Abstract
Baseball pitching relies on biomechanics and kinetics, where the pitcher's body works to produce power and pitch accuracy. Analyzing movement sequences, from wind-up to ball release, highlights the significance of joint angles and force in relation to the velocity and location of the pitch. Mastering these principles not only improves the pitcher's overall performance, but also helps prevent injuries. The effect of knee flexion at ball release and stride length on velocity were tested and analyzed in high school baseball pitchers. Our research is comparable to other studies when looking at values of knee flexion angle and stride length as a percentage of body height. A backwards stepwise regression was used to look for predictive ability of kinematics in relation to ball velocity. It was found that there is not significant correlation between the values of knee flexion at ball release and velocity (p=-0.431) as well as stride length as a percentage of body height and velocity (p=0.454). Future studies are encouraged to analyze baseball pitching mechanics at various angles of knee flexion to determine a more direct correlation with ball velocity.
