However, hamstring associated weakness, so strengthening exercises are required to treat Strengthening consist of concentric and eccentric exercises, differ in the direction muscle contraction. This study aimed observe effect concentric, eccentric, on length, endurance, power following tightness. 49 players who experienced participated this study. Participants were divided into three groups consisting Nordic Exercise (NHE), Leg Curl (LCE), control group (CTRL) - only did exercises. The carried out for 6 weeks, times per week. sit reach test, Passive Knee extension Single leg bridge dynamometer tests used determine changes before after One-way ANOVA was performed compare between groups. All participants found be good category (28.78±5.53 cm) test had low (39.13±16.77) intervention series. shown not significantly different (p>0.05) as well ROM. Single-leg bridging differed (p<0.05).This suggests tight correlated length. Concentric exercise increased strength more than stretching. While endurance muscle.
