 According to a new study, professional baseball pitchers with higher accuracy exhibit greater lead knee extension at ball release and lower throwing arm kinetic values than less accurate pitchers. The findings are published in the American Journal of Sports Medicine. Understanding pitching biomechanics can help athletes and their coaches improve pitching performance while potentially reducing injury risk. Although much has been learned so far, the kinematic and kinetic differences between high and low accuracy pitchers still aren't clear. In addition, shoulder and elbow injuries remain major problems among professionals, emphasizing the need to further study and optimize pitching parameters. To learn more about how kinematics relate to pitching accuracy, the study examined motion capture data for 121 professional pitchers who threw 8 to 12 fastballs each during a testing session. The pitchers were grouped based on pitch accuracy and various kinematic and kinetic parameters were compared. Interestingly, the high accuracy pitchers had lower shoulder internal rotation torque, elbow varus torque, and elbow medial force than the low accuracy pitchers, but were able to achieve the same ball velocity. This finding suggests that pitchers with greater accuracy may use their bodies more effectively to create throwing force. It also suggests that high accuracy pitchers might have reduced risk of shoulder and elbow injury because of the theoretically lower strain on these joints. Furthermore, compared to the low accuracy pitchers, the high accuracy pitchers had a straighter lead knee through the entire pitch. This greater knee extension may provide a more stable foundation and improve energy transfer from the lower body to the upper body, allowing the throwing arm to maintain accuracy. Importantly, the pitches for this study were thrown during designated test sessions, not real games, with only fastballs thrown. In addition, the pitch locations were assessed by coaching staff, so bias and human error may have occurred. Finally, actual injury incidents was not examined, so the proposed effects on injury risk are only theoretical. They couldn't be verified. Overall, the results suggest that more accurate professional baseball pitchers exhibit conservative throwing arm kinetics and greater lead knee extension at the end of the pitch than less accurate pitchers. Therefore, professional pitchers seeking to improve their accuracy and theoretically reduce their injury risk may benefit from increasing lead knee extension throughout the pitch.
