Resistance Band Training Versus Nordic Hamstring Exercise on Hamstring Strength Among Football Players

Study Overview
=================
Brief Summary
-----------------
The major aim of this project to compare the effects of Resistance band training and Nordic hamstring exercise on hamstring strength among football players.

Detailed Description
-----------------
Hamstring strength is important in football players and plays an important role in their sprint gait cycle. Football players should develop sprinter-like musculature in order to benefit their body strength and power hence preventing from hamstring strain injuries. Professional and recreational sports like Football, hamstring muscle strength training is commonly used to increase and balance lower body strength and power.

Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Group A: Nordic Hamstring Exercise<br>This group includes 15 male participants who will be given 10 minutes of warm and cool down sessions that includes stretching. Number of sets and repetitions progressively increase i-e: Week 1 - 2 sessions with 2 sets of 5 repetitions each. Week 2 - 2 sessions with 3 set of 5 repetitions each. Week 3 - 2 sessions with 4 set of 6 repetitions each. Week 4 - 2 sessions with 4 set of 8 repetitions each. | Other: Nordic Hamstring Exercise<br>* To perform Nordic Hamstring Exercise, the subject was in kneeling position on the mat, arms by the side or in front of the chest, knee in 90-degree flexion and ankles well stabilized with the help of a therapist which is positioned behind the subject. Then subject was asked to lean forward by using the hamstring muscles by extending while trying to resist the forward fall, he should lean forward from the knee and not from the hip. 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 them repeat the procedure again.<br>|
| Experimental: Group B: Hamstring Curl with Resistance Band<br>This group includes 15 male participants who will be given 10 minutes of warm and cool down sessions that includes stretching. Number of sets progressively increase i-e: Week 1 - 2 sessions with 2 sets of 15 repetitions each. Week 2 - 2 sessions with 3 set of 15 repetitions each. Week 3 - 2 sessions with 4 set of 15 repetitions each. Week 4 - 2 sessions with 4 set of 15 repetitions each. | Other: Hamstring Curl with Resistance band<br>* Traditional Hamstring Curl by using Resistance band. Resistance Band: Thera-band Green, 4.6 kg resistance at 100% elongation<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Modified sphygmomanometer Test | Modified sphygmomanometer is a non-invasive test and method which may provide reliable, rapid and valid measurement of assessing hamstring strength in field-based sports. | 4 weeks | 
| Manual Muscle Test (MMT) | Manual muscle test (MMT) is a procedure for the evaluation of strength of individual muscle or muscles group, based upon the effective performance of a movement in relation to the forces of gravity or Manual Resistance through the available Range of motion (ROM). Manual Muscle Testing Grading System from 0=No visible or palpable contraction to 5= full range of movement against gravity, maximal resistance. | 4 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 40-yard dash Test | Subjects were asked to be ready in a starting position with the appropriate foot position behind the starting line without any physical movements and subjects ran up to 40-yard when the signal was given out. The stopwatch was started when the players started to run and stopped when they had reached the finishing line. The procedures were repeated for the second time. Two trial results were documented and the best result was taken. | 4 weeks | 
| Muscle soreness rating following exercise | Participants used a 10-point Numeric Pain Rating scale to record the level of muscle soreness experienced after 1, 2, 4-week training sessions. Ratings of soreness intensity will be assessed consisted of a single 0-10 scale, with 0 indicating no soreness at all and 10 indicating the greatest soreness they could imagine. | 4 weeks |
