Aim: To Study short term effect of Isolytic contraction on Hamstring flexibility in asymptomatic subjects with hamstring tightness with respect to active knee extension test, Straight Leg Raise test and Lumbar Lordosis Index.

Objectives: The Objectives of the study are as follows:(1) To find effect of Isolytic contraction on hamstring flexibility. (2) To find effect of Isolytic contraction on static and dynamic hamstring flexibility.

Method: This study was conducted for the duration of 6 months. 300 subjects of age 20 to 40 years were screened out of which 276 subjects were selected for the study depending on the inclusive and exclusive criteria. Asymptomatic subjects with AKT <20 degree in the age group of 20 to 40 years were included in the study. These subjects were then divided into 2 groups Pre-treatment assessment and Post-treatment assessment were recorded.

Results: Statistically significant differences in the AKT, SLR, and LI were seen between the two groups. AKT (Right) It indicated that it was extremely significant (p<0.0001) and (p = 0.0079) in the interventional group subjects. AKT (Left) It indicated that it was extremely significant (p < 0.0001) and (p = 0.6384) in the interventional group subjects. SLR (Right) It indicated that it was extremely significant (p<0.0001) and (p = 0.1199) in the interventional group subjects. SLR (Right) It indicated that it was extremely significant (p < 0.0001) and (p = 0.2819) in the interventional group subjects. Intra group analysis of these values within the group was done using Wilcoxon test and the Inter group analysis between the groups was done by Mann- Whitney test.

Conclusion: The study results concluded that there was a significant result using isolytic contraction on hamstring flexibility in asymptomatic subjects having hamstring tightness with respect to Active knee extension test, Straight leg raise test and Lumbar lordosis index.
