AbstractIntroduction: Hamstring flexibility is crucial for athletic performance and injury prevention. Various therapeutic techniques have been explored to improve hamstring flexibility, with dynamic cupping and Active Release Technique (ART) being two popular methods. However, limited research exists comparing the efficacy of these interventions. Need to Study: Need of study is to compare that which technique is more effective on enhancing hamstring flexibility in recreational athletes either dynamic cupping or active release technique. Method: This study involved 30 recreational athletes randomly divided into two groups. Group A (n=15) received dynamic cupping therapy, while Group B (n=15) underwent Active Release Technique (ART). Both groups received three treatment sessions over three days. Hamstring flexibility was assessed using a goniometer, and pain intensity was measured using the Numeric Pain Rating Scale (NPRS). Conclusion: In summary, this study indicates that both dynamic cupping and Active Release Technique (ART) effectively improve hamstring flexibility and reduce pain in recreational athletes. However, ART demonstrated slightly greater effectiveness in enhancing flexibility compared to dynamic cupping. These findings suggest that while both techniques are viable options, ART may be the preferred choice for athletes aiming to optimize hamstring flexibility and prevent injury. Future research should explore larger sample sizes and longer follow-up periods to further elucidate the comparative benefits of these interventions.
