BACKGROUND: Hamstring tightness is common among football players, which frequently results in hamstring injuries. Although the exact cause of hamstring tightness is unknown, decreased hamstring extensibility may play a role. Stretching techniques of various types have been used to improve muscle flexibility in rehabilitation and sports. Passive stretching is one of the most commonly used methods, and the recent addition of other techniques such as ballistic stretching, Proprioceptive Neuromuscular Facilitation (PNF) techniques with variants have been effective. The current study aimed to compare the effects of Active releasing technique and Mulligan bent leg raise in footballers with hamstring tightness. AIM AND OBJECTIVE: To determine the effectiveness of Active releasing technique and Mulligan bent leg raise in reducing hamstring tightness among football players. METHOD: STUDY DESIGN: Experimental study. SAMPLING TECHNIQUE: Convenient Sampling technique. SAMPLE SIZE: 20 FOOTBALL PLAYERS. RESULT: The values were statistically analysed using paired ‘t-test and the Unpaired ‘t-test. The statistical analysis made with the quantitative data revealed a statistically significant difference between Group A and Group B and also within the group. The post-test mean value of sit and reach flexibility test of group A was 29.40 and group B was 28.50. This showed that the treatment given for group A is comparatively more effective than group B. CONCLUSION:This study shows that there was an improvement in hamstring flexibility in Active release technique as well as Mulligan bent leg raise among footballers with hamstring tightness. However, Active release technique is better as compared to Mulligan bent leg raise technique to improve hamstring flexibility and range of motion in footballers.
