Why the study?
The study was conducted to compare hamstring flexibility between federated soccer and non-federated adolescents, and to evaluate the effect of age and weight status on hamstring flexibility.
Does federated soccer practice improve hamstring flexibility in healthy adolescents compared to non-federated students?
Does federated soccer practice improve hamstring flexibility in healthy adolescents compared to non-federated students?
Federated soccer practice is associated with better hamstring flexibility in adolescents, while higher BMI is associated with reduced flexibility.
Soccer participation was associated with better flexibility in adolescents; leaves open causality and BMI effects in prospective trials.
The aim of this study was to compare the hamstring flexibility between federated soccer and non-federated adolescents, and also to evaluate the effect of age and weight status on hamstring flexibility. The participants were 234 students (11–18 years old) divided into: (i) G1: non-federated (n = 127), and (ii) G2: federated in soccer (n = 107). The deep flexion of the trunk (DF) test and the sit and reach test (SRT) were performed. G2 showed higher values for the DF and SRT compared to G1 (p < 0.05). Both flexibility tests correlated positively (r = 0.4, p < 0.001). Body mass index (BMI) was negatively correlated with the DF test (r = −0.3, p < 0.001), but not with the SRT. Divided by BMI, the underweight and normal weight groups had higher scores in the DF test compared with the overweight and obese groups (p < 0.001). BMI was negatively correlated with hamstring flexibility. Federated soccer students present higher scores of hamstring flexibility.
