The Relationship between Previous Lower Extremity Injury, Body Weight and Bilateral Eccentric Hamstring Strength Imbalance in Young Soccer Players
Journal Title: Montenegrin Journal of Sports Science and Medicine - Year 2018, Vol 7, Issue 2
Abstract
Th is study aims to investigate the eff ect of lower extremity (LE) injuries on bilateral hamstring eccentric strength imbalance (HSI) and to determine the relationship between body weight (BW) and HSI in young male soccer players. Eighty-eight young soccer players aged 14-19 in Turkey voluntarily participated in this study. Eccentric hamstring strength measurements were taken using a NordBord® Hamstring Testing Device. To obtain the LE backgrounds of the participants, individual interviews were administered to the players, and the obtained data were verifi ed through a review of previous injury records. While 22 (25%) out of 88 players reported LE injuries in the previous two years (injured players (IP)), the rest of them (75%) did not report any LE injuries (non-injured players (NP)). HSI values as peak forces were computed by extracting the weaker leg values from the stronger leg values. Both the Analysis of Variance (ANOVA) and the Analysis of Covariance (ANCOVA) were performed, controlling the BW eff ect in order to test the eff ects of LE injuries on HSI. Correlation analysis was also conducted, taking into consideration the previous research fi ndings on the relationship between body weight and strength variables. Th ere was signifi cant relationship between BW and HSI ((p<0.05) (0.04> r >0.02)) and non-signifi cant results for HSI (F (1.85) =0.578, p>0.05). However, the eff ect of BW was signifi cant for HSI (F (1.85) =3.91, p<0.05, η2 = 0.068). Th is study supported the hypothesis that hamstring muscle strength imbalance is not aff ected by lower extremity injuries and that body weight is a factor that may aff ect strength imbalance.
