In clinical settings, different stretch holding times<br>are used to treat hamstring tightness. The purpose of the study was to determine effects of different static&nbsp;stretch holding-times on hamstring muscles flexibility and their impacts on improving range of motion&nbsp;(ROM) of knee extension in adults. This experimental work was conducted on students of University of Lahore<br>from December 2013 to March 2014. The study comprised of 60 subjects with asymptomatic tightness&nbsp;of hamstrings muscles and subjects were aged between 18-26 years (irrespective of their gender). Range of&nbsp;motion at knee joint was measured by universal goniometer before the commencement of stretching technique.&nbsp;Static stretching was applied to group A, B and C with 30, 60 and 90 seconds holds, respectively.&nbsp;Stretches were exerted at frequency of three sessions per week and three repetitions per session. Reevaluation&nbsp;of ROM was performed after 4 and 6 weeks. The mean values of ROM of knee extension showed gain<br>in range after applying static stretching at 30s, 60s and 90s holding times. By applying repeated measure&nbsp;analysis of variance (ANOVA), the p-values were found to be statistically significant (p&lt;0.001) for static&nbsp;stretching techniques with 30s, 60s, 90s holding times, respectively. Based on these finding, it is plausible to<br>conclude that application of static stretching at holding times of 30, 60 and 90 seconds can significantly improve&nbsp;the ROM of knee extension. Stretching techniques with different holding times were equally effective&nbsp;in improving knee extension and gaining hamstring flexibility in adults.</p> ER -
