Hamstring tightness is a common problem among students and young adults, often leading to reduced flexibility, musculoskeletal discomfort, and risk of injury. Different stretching methods are used in physiotherapy practice to improve muscle length and flexibility. Post-Isometric Relaxation (PIR), a type of muscle energy technique, and Active Static Stretching (ASS) are two commonly applied methods, but evidence comparing their effectiveness in improving hamstring flexibility among Allied Health Sciences students remains limited. This randomized controlled trial aims to compare the effects of PIR and Active Static Stretching on hamstring flexibility in healthy university students. Participants will be randomly assigned to either PIR or ASS groups and undergo stretching sessions for a specified duration. Hamstring flexibility will be measured using the Active Knee Extension test before and after the intervention. The findings will provide evidence to guide physiotherapy education and clinical practice on the most effective stretching technique for improving hamstring flexibility.
