Bilateral Asymmetry and Dynamic Balance Changes within a Competitive Season in Collegiate Athletes.
Abstract: This study will investigate whether muscular asymmetry is associated with dynamic balance asymmetry in different sports, and whether asymmetry changes throughout the sport seasons. Due to athlete’s having a preference to use one side of the body when performing sports, it is feasible that differences in strength between the limbs could lead to differences in stability. To our knowledge no previous research has been conducted on seasonal changes in bilateral muscular asymmetry nor dynamic balance asymmetry. The results obtained will help us understand changes in muscular and dynamic balance symmetry throughout the course of an athlete’s competitive season. This is a first step to determine possible cause of injury in this population. Approximately 200 collegiate athletes will be recruited to undergo standardized protocols for whole body Dual Energy X-Ray Absorptiometry (DXA) scans, anthropometric measurements, and Y balance test for both upper and lower body. These tests will be performed three different times throughout the year, corresponding with the off-, pre-, and post-season of the participant’s sport. The long-term goal is to improve training protocols that eliminate muscular and dynamic balance asymmetry, which could ultimately result in preventing sports injuries.
