Brief Summary  

Objective: 

To compare the immediate effects of eccentric training versus dynamic range of motion training on hamstring muscle in recreational badminton players using vertical jump test and active knee extension test.

In India, badminton is one of the most popular sports and is suitable for all age groups. Around 30.9% of players in Badminton suffer from Strain as a result of muscular-fiber tears due to overstretching that can be reduced by increasing muscle flexibility. Badminton is a non-contact racquet sport requiring combinations of swift turns, high speed jumps, lunges with quick changes in direction and rapid arm and lower extremity movements from a wide range of postural positions.Due to such rapid movements there is high vulnerability for players to sustain injuries. The hamstring muscle is said to be the most frequently injured muscle in badminton with decreased flexibility being one of the major predisposing factors

Eccentrically training a muscle through full range of motion decreases injury rates and increases flexibility and athletic performance.“Dynamic Range of Motion” has warming effect in the muscle and  help in accommodating to the stretch, making it more pliable, thus leading to an increase in the flexibility of the muscle.

       In spite of many studies and researches done on eccentric training and dynamic range of motion training individually on hamstring flexibility, there are not many done comparing both the techniques on hamstring muscle in recreational badminton players. Thus the present study aims to determine the immediate effects of eccentric training and dynamic range of motion training on hamstring muscle in recreational badminton players.
