Reliability of the hop test and asymmetry index in University athletes: A cross-sectional study assessing injury risk

Abstract

This study aims to assess the reliability of hop tests among healthy university athletes and to identify leg asymmetries through these assessments. A cohort of 212 university athletes, active in sports, participated in the study. Hop tests, comprising four distinct procedures, were administered to evaluate lower extremity strength. The hop tests demonstrated high reliability, with reliability coefficients ranging from 0.704 to 0.990. Examination of asymmetry indices revealed mean values of 101.07%, indicative of symmetrical limb function among participants. Gender -based differences were notable in hop test results, particularly in the crossover hop test, which showed significant asymmetry ( p <.05). Age -related variances were observed solely in the single -leg hop test ( p <.05), while asymmetry indices did not significantly differ across age groups ( p >.05). As a result, it can be concluded that strength imbalances between gender and age are important functions affecting explosive power and the hop test gives reliable results in measuring these parameters. Moreover, the study hints at a low risk of injury among athlete students, given the inferred association between asymmetry indices and injury risk. Engaging in tailored physical activities and sportsspecific training regimens may foster and sustain normal limb symmetry, potentially mitigating injury risks.
