The Relationship between Previous Lower Extremity Injury, Body Weight and Bilateral Eccentric Hamstring Strength Imbalance in Young Soccer Players
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 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
Investigation of the relationship between strength and dynamic balance performance in elite wrestlers
Background. Wrestlers rely heavily on the abilities of strength and balance to ensure success. Although previous studies have investigated the effects of different training methods on the athletic performance of strength and balance, there are a limited number of studies aimed at examining the relationship between these two performances
