Abstract
The lower limbs, in addition to serving as the base of support, are also the main means of locomotion. The presence of any abnormalities in these limbs can cause considerable difficulties in daily life and sports activities. Therefore, the aim of the present study was to compare the lower limb alignment in 11–13-year-old rope-skipping and non–rope-skipping male students. The statistical population of this study included all 11–13-year-old male students in Abhar city during the 2018–2019 academic year. Among these students, 35 boys who had at least three years of rope-skipping experience were selected using a questionnaire, and another 35 students were randomly chosen as the control group. Genu varum and genu valgum deformities were assessed using the IM–IC index. A universal goniometer was employed to measure genu recurvatum, and the Staheli index was used to evaluate foot posture. Data were analyzed using SPSS version 22. The Shapiro–Wilk test was applied to check the normality of data distribution, and independent t-tests were used to determine differences between the groups. The findings revealed significant differences in the prevalence of lower limb abnormalities between the rope-skipping and non–rope-skipping groups (p = 0.001 for genu varum, p = 0.021 for genu valgum, p = 0.026 for genu recurvatum, and p = 0.036 for foot posture). Based on the results of this study, it can be concluded that engaging in rope-skipping activities for at least three years may help prevent or reduce lower limb abnormalities.
