Background & Objective: Active stretching is purported to stretch the shortened muscle and simultaneously strengthen the antagonist muscle. The purpose of this study was to determine whether active and passive stretching results in a difference between groups improving hip flexion and knee extension ROM subjects with hamstring tightness. Subjects and methods: Thirty subjects who showed decreased ROM, presumably due to hamstring muscle tightness. The subjects, who had age of 18 to 30 years, were assigned to either an active stretching group or passive stretching group. Before the procedure, ROM of hip flexion with knee extension forward reach test and muscle length test was measured before and after 3 weeks of the start of the study. Results: Results from this study found that Flexibility of hamstring muscle & ROM of hip flexion with knee extension is increased in group with Passive Stretching than the group with Active Stretching. Conclusion: Passive Stretching of hamstring muscle in normal individuals is more effective than Active Stretching.
