ASYMMETRICAL MUSCLE DEVELOPMENT IN SPECIALIZED ATHLETES AND ASSOCIATED INJURY RISK
PublisherThe University of Arizona.
AbstractHamstring strains and knee sprains are occurring in professional sports at an alarming rate that might suggest athletes are being subjected to increased injury risk. This increased risk may come from the asymmetric development of the quadriceps and hamstring muscle groups. Injury surveillance systems and individual studies have revealed a significant relationship between the rate of occurrence of lower limb injury and a low eccentric hamstring to concentric quadriceps strength ratio. Nevertheless, the current literature contains conflicting studies on the effects of sport-specific training on muscle development. While muscle asymmetries might play a role in injury risk, there has not yet been a proven association between sport-specific training and the development of muscle asymmetries. The results of multiple studies still suggest that hamstring and knee injuries can be prevented through the implementation of a balanced workout program and flexibility training.
