SUMMARY
Objective. To evaluate the ability of Single Leg Squat (SLS) and Vertical Drop Jump (VDJ) tests to predict lower limb injuries in professional footballers.
Methods. In a prospective cohort study SLS and VDJ scores were recorded before the start of the season and the lower limb injuries were recorded as followed up during a 9-month season (2021-2022). Logistic regression analysis was used to determine the accuracy of the prognosis of SLS and VDJ tests.
Results. During the nine months of follow up, a total of twenty-five lower limb injuries (in twenty-three footballers) were recorded for 121 professional male footballers. The model explained 22% (Nagelkerke R2) of the variance in lower limb injury and correctly predicted 85.1% of cases. ROC analysis showed significant accuracy of the VDJ performance score of the footballer (AUC 0.659, 95%CI 3.639-63.434, p = 0.001, OR = 0.204) in discriminating between injured and uninjured players. The optimum cut-off level of the VDJ performance score of the football players was 0.5.
Conclusions. VDJ test is a suitable tool for predicting lower limb injuries in professional male footballers, but SLS cannot be used as a reliable screening tool.
