This study aims to investigate the effect 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 (R) Hamstring Testing Device. To obtain the LE backgrounds of the participants, individual interviews were administered to the players, and the obtained data were verified 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 effects of LE injuries on HSI. Correlation analysis was also conducted, taking into consideration the previous research findings on the relationship between body weight and strength variables. Th ere was significant relationship between BW and HSI ((p<0.05) (0.04>r>0.02)) and non-significant results for HSI (F (1.85) =0.578, p>0.05). However, the eff ect of BW was significant for HSI (F (1.85) = 3.91, p<0.05, eta 2 = 0.068). Th is study supported the hypothesis that hamstring muscle strength imbalance is not affected by lower extremity injuries and that body weight is a factor that may aff ect strength imbalance.

This study aimed to investigate the effects on the dynamic balance of two different resistance training in male basketball players. 25 male basketball players who were over 18 participated in the study voluntarily. Participants were divided into two groups by using random sampling method as VertiMax strength training group and traditional strength training group (VertiMax, n=13; classic, n=12). Both training programs were administered 3 times a day for 6 weeks. In standing position, the dynamic balance valu...
The Effects of Sex, Limb Dominance, and Soccer Participation on Knee Proprioception and Dynamic Postural Control
CUĞ, MUTLU; Wikstrom, Erik A.; Golshaei, Bahman; Kirazcı, Sadettin (2016-02-01)
Context: Both female athletes' participation in soccer and associated injuries have greatly increased in recent years. One issue is the 2-9 times greater incidence of noncontact anterior cruciate ligament (ACL) injuries in female athletes relative to male athletes in comparable sports. Several factors such as limb dominance and sporting history have been proposed to play a role in ACL incidence rates between male and female athletes. However, evidence about the effects of these factors and how they interact...
Effects of muscle fatigue on shooting accuracy in handball players
Şimşek, Beyza; Korkusuz, Feza; Department of Physical Education and Sports (2012)
The purpose of the study was to investigate the effects of muscle fatigue on shooting accuracy in male handball players. Sixteen elite young male handball players (age: 17.12±1.74 year; height: 185.26±7.17; body mass: 78.93±11.07) volunteered to participate in the study. The study composed of laboratory and field test sessions. In the laboratory test, maximal oxygen consumption (VO2max) obtained from treadmill running test, blood lactate concentration, heart rate monitoring at resting and every 3 minutes du...
Effects of swiss ball training on knee joint reposition sense, core strength and dynamic balance in sedentary collegiate students
Cuğ, Mutlu; Korkusuz, Feza; Department of Physical Education and Sports (2012)
The purpose of this study was to investigate the effects of Swiss ball training on (1) knee joint reposition sense (knee proprioception), (2) core muscle strength and (3) dynamic balance in sedentary collegiate students. In this thesis, two different participant groups and two different training methods were used. In order to evaluate the effect of Swiss ball training on knee proprioception and core strength, 3 days per week training was conducted throughout 10 weeks (Study 1). In order to evaluate the effe...
