This thesis explores injury trends in baseball players across different positions and throwing techniques, focusing on elbow and shoulder injuries. By comparing infielders and outfielders, the study analyzes the impact of biomechanics and throwing styles on injury patterns.

Injury Trends as a Function of Player Position Erin Schneider New Mexico State University Athletic Training Education Honors Thesis
Introduction • Player Positions vs Pitchers • “few to no reports on injury demographics in baseball players other than pitchers at any level of play” exist (Axe, Windley, and Snyder-Mackler, 2001, p. 268)
Throwing Technique • Infielders vs. Outfielders • Infielders used: Sidearm, Overhead, and Underhand • Outfielders used: Overhead • Sidearm vs. Overhead • Planted position vs. non-planted position • Different velocities required
Biomechanics- The Basics • Overhead • Phases: Arm Cocking, Acceleration, Deceleration • Valgus (Lateral) Torque created during arm cocking • Sidearm • Phases: same as overhead • HOWEVER, shoulder has greater horizontal abduction at “top position” • Valgus force increased
Hypothesis • A higher trend towards elbow injuries will be found for infielders • Infielders will display a higher injury trend overall • Outfielders will show a greater a shoulder injury trend due to the repetitive overhead throwing motion
Methods • Participants: 24 participating Baseball athletic trainers (ATCs) out of 295 invited • Instrumentation: Survey • Procedures: ATCs were contacted via email; answers to the surveys were to exclude pitchers • Data Analysis
Results Number of Individual Injuries Sustained by Infielders and Outfielders
Results (cont.) Number of Individual Injuries sustained by Infielders and Outfielders
Discussion • No real trend for shoulder injuries • Injury frequencies support hypothesis that infielders will show a higher trend towards elbow injuries • Certain schools seemed to sustain more injuries than others
Limitations • 8% return on surveys • Problems with clarity in the questions • Discrepancies with numbers
For the Future… • Need more evidence for results to be determined conclusive
