Effects Of Game Pitch Count And Body Mass Index On Pitching Biomechanics In 9-To 10-Year-Old Baseball Athletes, Jim D. Darke, Eshan M. Dandekar, Arnel L. Aguinaldo, Scott J. Hazelwood, Stephen M. Klisch

Biomedical Engineering

Background: Pitching while fatigued and body composition may increase the injury risk in youth and adult pitchers. However, the relationships between game pitch count, biomechanics, and body composition have not been reported for a study group restricted to 9-to 10-year-old athletes.

Hypothesis: During a simulated game with 9-to 10-year-old athletes, (1) participants will experience biomechanical signs of fatigue, and (2) shoulder and elbow kinetics will correlate with body mass index (BMI).

Study Design: Descriptive laboratory study. Methods: Thirteen 9-to 10-year-old youth baseball players pitched a simulated game (75 pitches). Range of motion and muscular output tests were conducted before and …
