Abstract: Hamstring tightness is widely recognized as a risk factor for injury, as reduced flexibility can hinder efficient movement and increase the likelihood of muscle strain. Improving flexibility helps muscle tissue better tolerate mechanical stress during physical activity. This study aimed to determine the more effective method for enhancing hamstring flexibility by comparing Eccentric Training and Proprioceptive Neuromuscular Facilitation (PNF) stretching. Sixty track athletes (27 males, 33 females) aged 18-26 years, all with bilateral hamstring tightness and specializing in sprint events (100m, 200m, 400m), participated in this experimental pre-post study. Participants were randomly divided into two groups of 30: one group received PNF Contract-Relax-Antagonist-Contract (CRAC) stretching, while the other performed Eccentric Training. Both interventions were conducted over a period of three weeks, with five sessions per week. Flexibility outcomes were measured using the Active Knee Extension, Passive Straight Leg Raise, and Sit and Reach tests. Analysis using paired and independent t-tests showed significant improvements in hamstring flexibility in both groups (p<0.001), with the PNF-CRAC group demonstrating significantly greater gains. The findings suggest that while both methods are effective, PNF stretching is superior for improving hamstring flexibility.
