Brief Summary

The aim of this research is to compare the effects of dose response of Nordic hamstring exercise on muscle strength, agility and speed in athletes a randomized controlled trial done at JKD cricket academy and sports centre, Peshawar. The sample size was 34. The subjects were divided in two groups, 17 subjects in Group 1 which will do high volume Nordic hamstring exercise and 17 in Group 2 which will do low volume Nordic hamstring exercise. Study duration was of 6 months. Sampling technique applied was non probability purposive sampling technique. Only 18-30 years athletes with BMI between 18.5-24.5 kg/m2 were included. Tools used in the study are Single leg hamstring bridge (SLHB), Agility t-test, 30-m speed test and muscles size .Data will be analyzed through SPSS 21.

Outcome Measures

Primary Outcomes (1)

• Single leg hamstring bridge test

  Single leg hamstring bridge (SLHB) is a clinical test for hamstring function used at elite level for the screening programs. To perform this test, person lies on his back with bent knees, hip distance apart, and feet flat on mat stacked under the knees. Extend one leg long towards the ceiling. Squeeze glutes and lift hips off the mat into a bridge. Lower and lift the hips for desired number of repetitions and repeat on other side

  4th week

• 30-m speed test

Interventions

High volume nordic hamstring exercise OTHER

To perform Nordic Hamstring Curls, the person will kneel on a pad (for knee comfort) and lower under control, his ankles must be stabilized and kept in a place with the help of a partner, but can also use a moveable object or a loaded barbell can also be used to achieve the stability. The person must then extend his hamstrings in order to lean forward, he should lean forward from the knee and not from the hip. The movement must be kept controlled and slow. The person should go as forward/low as possible but without the help of hands or arms. The only time one can put his hands in front of him is when he can't rely on his legs and then push himself back to starting position and then repeat the procedure again.Group 1 will do the Nordic hamstring exercise with protocol 3 repetitions × 3sets× 3 times for 4 weeks.
