Injury RiskWe found that current HS athletes recalled a statistically higher incidence of sustaining an injury that they attributed to specializing in 1 sport when compared with current collegiate and current professional athletes. This may suggest that early sport specialization can be a potential factor in the occurrence of early sport-related injury, but there are, of course, multiple factors affecting the occurrence of injury with sport. It is important to emphasize that these data are a reflection of each surveyed athlete’s ability to recall an injury that interrupted sports participation and required specific treatment, but we did not report on any actual injury data in our study.
