Comparing the immediate effect of myofascial release versus IASTM on hamstring in long-distance runners

Background: Long distance runners are more prone to have posterior muscle tightness in lower extremity. Tight hamstring muscles are one of the significant risk factors for hamstring injury in runners. By Improving the flexibility of the tight muscles, we can decrease the risk of hamstring injuries in long distance runners. Objective: The objective of this comparative study was to examine the effectiveness of techniques of soft tissue release; the myofascial release and the instrument assisted soft tissue mobilization in improving hamstring flexibility in long distance runners so as to help prevent or reduce the incidence of hamstring injuries in long distance runners. Methods: 100 long distance runners based on inclusion and exclusion criteria were equally divided into Group A and Group B. Group A subjects were given myofascial release (MFR) Group B subjects were given instrument assisted soft tissue mobilization (IASTM). The outcome measures used were the Sit and reach test and Lower extremity functional scale (LEFS). The first test is objective in nature while the second one is subjective. Assessments using the two scales were done prior to commencement of the exercise intervention and post its completion. The intervention was one time intervention. Results: Subjects showed statistically significant results in the favor of the Instrument assisted soft tissue mobilization in classical sit and reach test, which gives a measure of hamstring flexibility. Furthermore, statistically significant results surfaced in favor of the Instrument assisted soft tissue mobilization in the lower extremity functional scale, which is a functional assessment scale questionnaire, respectively. Conclusion: The Instrument assisted soft tissue mobilization was more effective than the Myofascial release in improving hamstring flexibility immediately in long distance runners. (p
