The Effect of Static Stretch and Dynamic Range of Motion Training on the Flexibility of the Hamstring Muscle

Introduction: A normal flexibility is required for an appropriate posture and entire activity in daily life. Hamstring is the muscle that is more prone for tightness. It present in all age groups and it increases with age and more over it is the muscle that is most prone to injuries during sporting activities. With regard to various methods that contribute to increasing flexibility of hamstring muscles, the current study aimed at investigating immediate effects of static stretching and dynamic range of motion training on hamstring flexibility increasing muscle flexibility. Methodology: 30 patients, age range 21-50 years, diagnosed with the Population who had hamstring tightness and divided equally into two groups-Group A and Group B .In Group B-Static Stretch exercise and in Group A-Dynamic Range of Motion Training exercise. Result: Pre and post evaluation of active knee extension test was taken. Result shows that there was significant improvement noted in both the groups (GROUP A: P value .000, t value:-17.9) and (GROUP B: P value: .000, t value:-17.6) Conclusion: Both the static stretch and dynamic exercise can be considered as an effective method for increasing flexibility and improving functions with hamstring tightness patients. Key words: Hamstring flexibility, Dynamic range of motion, and static stretch.
