Aim of the study- To compare the dynamic balance in young females with normal Body Mass Index (B.M.I.) with and without hamstring tightness. Method- It was a cross-sectional, comparative study. 22 young females were included in the study. Hamstring tightness was assessed using the Active Knee Extension (AKE) Test and based on the values; subjects were divided into 2 groups- Group A (with tightness) and Group B (without tightness). Star Excursion Balance Test (SEBT) was used to assess the dynamic balance in subjects from both groups. The data was analysed results were compared using appropriate statistical tools. The study showed that st Result- ar excursion balance test values were more in the group without tightness (p-value <0.0012) as compared to the group with tightness. Dynamic balance as Conclusion- measured by star excursion balance test is better in subjects without hamstring tightness as compared to subjects with hamstring tightness.
