Official title
Shoulder Strength in Light of Retroversion and Biological Age in Baseball Players
Overview
The purpose of this graduate student research study is to transform the existing concepts surrounding shoulder strength in baseball players, particularly in the context of retroverted shoulders.
Detailed description
The study aims to investigate the influence of biological age on shoulder strength in comparison to chronological age, providing insights into how these factors might interact in the context of athletic performance. Additionally, the investigators seek to develop a novel framework for injury prevention in baseball, addressing the critical research gap identified in the scope review. Furthermore, the investigators will conduct a comparative analysis between two different countries to deepen the understanding of baseball-related injuries, ultimately fostering a more comprehensive approach to athlete safety and health in the sport.
Interventions
- Other Strength and Range of Motion
Shoulder external rotation and internal rotation strength will be measured with a dynamometer at the end range, as well as at retroverted shoulder neutral and zero degrees for three times. Grip strength will also be measured three times using the dynamometer after the shoulder strength assessments.
Primary outcome measures
- Strength [Time frame: baseline reading on visit one]
