the relationship between genu varum abnormality and lower extremity’s performance and strength in teenage footballers

introduction: the aim of this study was to explore the relationship between genu varum abnormality and the performance and strength of lower extremity in teenage footballers. materials and methods: 60 young male football players with the mean age of 15.2± 0.78 yr, mean weight of 58.9 ± 3.39 kg and mean height of 166.6.21 cm participated in this study. kendall’s method and plumb line were used to evaluate subjects’ posture. genu varum was measured via a caliper. to assess the performance variables, one-leg squat for depth, one-leg hop for distance, single-leg triple hop for distance, vertical jump and t- test was tested for each athlete. independent t-test was used for statistical analysis of data. results: results of independent t-test revealed that performance variables were significantly different between two groups [vertical jump (p=0.005), one-leg squat for depth (p=0.019(, one-leg hop for distance (p=0.011), single-leg triple hop for distance (p=0.008) and t- test (p=0.003)]. discussion and conclusion: based on this study results, it can be concluded that posture can affect performance variables and genu garum abnormality may reduce performance.
