Risk Factors For Groin Injuries In Collegiate Soccer Players

PURPOSE: To investigate the prevalence and risk factors associated with groin injuries in collegiate soccer players. METHODS: 56 collegiate soccer players (33 males, 23 females) were recruited, and their basic information (e.g., playing experience, position, dominant foot, injury history) was recorded. Lower limb characteristics (lower limb length, muscle circumference, eccentric hip adductor (EHAD) and eccentric hip abductor (EHAB) strength) were measured, and participants completed the Copenhagen Hip and Groin Outcome Scale (HAGOS). Groin injuries were monitored over one season. Risk factors were analyzed using univariate and multivariate Cox proportional hazards regression models, time to groin injury was the outcome variable, while basic information, lower limb characteristics, and HAGOS scores were covariates. RESULTS: 27 groin injuries were reported among 18 players, resulting in an injury rate of 3.35 injuries per 1000 hours (males: 3.39/1000 hours; females: 2.65/1000 hours; p < 0.05). Injury rates were significantly higher in midfielders than in other positions (1.37/1000 hours, p < 0.05). Cox proportional hazards regression models revealed that a history of groin injury, the EHAD:EHAB strength ratio, and HAGOS pain scores significantly influenced the risk of groin injuries (p < 0.05). Specifically, players with a history of groin injury had a 6.206-fold greater risk compared to those without a history. For each unit increase in the EHAD:EHAB strength ratio on the unaffected side and affected side, injury risk was reduced by 97.0% and 96.2%, respectively. Each 1-point increase in HAGOS pain score was associated with a 3.4% reduction in injury risk. CONCLUSIONS: Male and midfield collegiate soccer players have a higher risk of groin injuries. A history of groin injuries, the EHAD:EHAB strength ratio, and HAGOS pain scores are critical risk factors for groin injuries that warrant attention.
