The TCU Division I Collegiate Athlete Study

The overall objective of this study is to identify risk factors for two of the most common types of injuries in collegiate athletics - orthopedic injuries and concussion injuries. Aim 1 of this study is to investigate risk factors for orthopedic injuries from a brief testing battery developed by the research team. Aim 2 of this study is to investigate risk factors for concussion injuries and subsequent sequelae after returning to play from concussion from the same brief testing battery developed by the research team. Additionally, we will examine the relationships between orthopedic injuries and concussion injuries in the collegiate athlete. Participants will participate in a pre-season battery of tests that include: * Balance assessment * Jump testing * Strength testing * Neurocognitive testing Subjects who sustain an injury will undergo repeat testing for comparison to baseline measures. Further, retrospective chart reviews of past medical history and prospective injury tracking will be collected on all subjects.
