Injuries to the throwing shoulder and elbow have become increasingly prominent in baseball athletes. Extrinsic risk factors such as workload volume and intensity, sport-specific biomechanics, and training environment have been theorized to impact injury rates in baseball pitchers (Post et al., 2020; Jayanthi et al., 2015). However, previous research is limited regarding these risk factors in collegiate pitchers. The goals of this dissertation were to enhance our understanding of how sport specialization, workload, and change over time affect pitching biomechanics in collegiate and high school pitchers.For the first two aims, a data collection instrument determined the magnitude of sport specialization in collegiate and high school baseball pitchers. Comparisons between specialization levels were made to determine if differences existed for collegiate and high school pitchers. Next, pitching biomechanics evaluations were conducted before (January) and after (August) the NCAA spring season to investigate the relationship of pitching biomechanics to competitive workload variables. Lastly, we tracked how pitching biomechanics change through four pitching evaluations spanning one year.We found that high-, moderate-, and low-level specialized collegiate pitchers threw with similar pitching biomechanics across groups. High school pitchers also demonstrated similar pitching biomechanics across groups, yet high-level specialized pitchers threw significantly faster (High: 36.4 ± 2.26 m/s; Low: 32.05 ± 1.92 m/s) and had significantly higher BMI (High: 24.18 ± 2.74; Low: 21.29 ± 1.87) than low-level specialized pitchers. Results also found shoulder abduction at stride foot contact (SFC), shoulder rotation at SFC, shoulder abduction at maximum shoulder external rotation, and maximum elbow valgus torque had strong negative correlations to workload variables. Shoulder Abduction at SFC significantly increased from pre- to post-season while Shoulder Rotation at MER significantly decreased. Finally, collegiate pitchers were able to improve, or keep within a target range, their pitching biomechanics from an initial evaluation to a fourth evaluation roughly one year later. By identifying how sport specialization, workload, and time interact with pitching biomechanics, clinicians may be able to develop specific rehabilitation strategies to best address a specific pitcher's needs.
