The aim of this study was to determine whether there are any differences in hamstring strength indices of isokinetic concentric and eccentric peak torques at 60 deg/sec and 180 deg/sec between hamstring injured (left / non dominant) and non-injured (right / dominant) leg in a hamstring-injured athlete. A 25-year-old male recreational athlete who was having hamstring injury, grade 2, twice in the past took part in the present case study. Hamstring concentric and eccentric peak torques were tested at two velocities: 60 and 180 deg/sec. The difference was found in concentric peak torque at 60 deg/sec. Future well - designed studies are needed to find out whether the relationship between strength testing and hamstring muscle injury.
