Sport Specialization's Impact on Female Adolescent Athletes' Lower-Extremity Neuromuscular Control: A Critically Appraised Topic.

Abstract

Nearly 60 million youth ages 6-18 participate in athletics within the United States. Over the last 30years, the outlook on youth sport participation has drastically changed, resulting in an increased emphasis on performance and college sport participation. These evolving expectations have created a sense of perfectionism, demanding more time and energy to be placed into a single sport, resulting in an increased prevalence of sport specialization, and consequently, an increased rate of injury. What is the impact of sport specialization on lower-extremity neuromuscular control in female adolescent athletes? Four studies were included, all comparing movement efficiency and movement patterns among multisport and sport-specialized female adolescent athletes. Three studies showed that sport specialization is associated with lower-extremity biomechanical alterations that are indicative of altered levels of neuromuscular control, which can predispose an individual to an increased risk of injury. One study concluded that no differences in neuromuscular control exist when comparing sport-specialized to multisport adolescent female athletes. Sport specialization has the potential to create negative alterations in a female adolescent athletes' lower-extremity biomechanics, leading to the creation of altered levels of neuromuscular control and a possible increased risk for injury. Level B evidence exists to support the conclusion that sport specialization negatively affects a female adolescent athlete's lower-extremity neuromuscular control.
