Patterns Of Participation And Performance In Youth Baseball Players, Amanda Arnold

Theses and Dissertations

Baseball is a popular sport to play in the United States, with approximately 13-17 million athletes participating across all levels of competition. Youth (9-12 years) and adolescent (13-18 years) players comprise the majority of this population playing at the club and high school levels, yet less than 10% of research studies include athletes <18 years old. Despite increased awareness of the risks surrounding sports participation, youth and adolescent baseball players continue to report overuse injuries at alarming rates.

The lack of high-quality research describing athletic performance and injury risk factors, such as sport specialization, in young athlete populations poses a significant knowledge gap in the literature. The current investigation sought to establish the incidence of upper extremity (UE) injuries while examining population-specific risk factors in …
