Abstract: Introduction Hamstring flexibility is crucial for good posture and movement. Tight hamstrings, often caused by prolonged sitting, can lead to stiffness, reduced range of motion, and pain in the lower back, pelvis, knees, and feet. Research shows that up to 40% of college students experience hamstring tightness. This study examines the immediate effects of Percussive Therapy (PT) and Active Release Technique (ART) on hamstring flexibility in young adults. ART, developed by Dr. Leahy, breaks tissue adhesions to relieve muscle tightness. PT, using a massage gun, loosens muscles, boosts blood flow, and improves flexibility. Research suggests PT can increase range of motion (ROM) without affecting muscle performance. Objective To compare the immediate effects of PT and ART on hamstring tightness in young adults and determine the more effective method for improving flexibility and mobility. Method This experimental study used simple random sampling to select 30 participants (ages 18-30). They were divided into two groups: o Group A (n=15): Received Percussive Therapy (PT) o Group B (n=15): Received Active Release Technique (ART) Hamstring tightness was assessed before and after intervention using the Active Knee Extension Test (AKET). Results The findings reveal that although both Percussive Therapy and Active Release Technique are effective in reducing hamstring muscle tightness and enhancing flexibility acutely, ART demonstrated a significantly greater improvement compared to PT. The statistically significant outcomes--both within and between groups--highlight the immediate therapeutic benefit of ART over PT in the treatment of hamstring muscle tightness in young adults. Conclusion PT and ART effectively reduce hamstring tightness and improve knee extension. However, ART was significantly more effective in increasing hamstring flexibility and range of motion.
