Injury risk factors related to sport specialization in high school basketball: a prospective study.

ABSTRACT Context Research that has examined the association between specialization and injury in basketball has been limited to cross-sectional or retrospective studies. Objective To determine whether specialization is a risk factor for injury among high school basketball athletes. Design Prospective cohort study. Setting Basketball players from 12 high schools participating in the National Athletic Treatment, Injury, and Outcomes Network Surveillance Program (NATION-SP) were recruited prior to the 2022-2023 interscholastic basketball season. Patients or Other Participants 130 athletes (mean age (SD) = 15.6 (1.3); girls’ basketball: n=68 (52.3%)). Main Outcome Measures Participants completed a questionnaire prior to the start of their school basketball season that had questions regarding participation in various specialized sport behaviors. During the basketball season, the school’s athletic trainer reported all athletic exposures (AEs) and injuries (regardless of time loss) for participating athletes into NATION-SP. Injury incidence (IR) and incidence rate ratios (IRR) with 95% confidence intervals 95%CI were calculated for the specialized sport behaviors previously described. Results There was no difference in injury risk between highly specialized and low specialized athletes (IRR 95%CI: 1.9 0.9, 3.7). Players who participated in basketball year-round were twice as likely to sustain an injury compared to those who did not play year-round (IRR 95%CI: 2.1 1.1, 3.6). Similarly, players who reported participating in basketball skills camps were at increased risk of injury compared to athletes who did not participate in basketball skill camps (IRR 95%CI: 2.5 1.2, 5.7). Conclusion Injury risk related to sport specialization in basketball may be specific to certain behaviors such as year-round play and participation in skills camps. Validated measures of comprehensive sport activity are needed to better measure specialization in youth sports to better determine injury risk related to sport specialization and develop injury prevention programs for basketball athletes.
