The purpose of the study was to find out the effect of yoga on selected physiological variables among college women students. It was hypothesized that there would be significant differences on selected physiological variables due to the effect of yoga among college women students.

For the present study pre test – post test random group design which consists of control group and experimental group was used. The subjects were randomly assigned to two equal groups of fifteen each and named as Group ‘I’ and Group ‘II’. Group ‘I’ underwent yoga training and Group ‘II’ has not undergone any training. The selected variables were assessed by bio-monitor. The data was collected before and after twelve weeks of training. The data was analyzed by applying dependent ‘t’ test. The level of significance was set at 0.05. The results of the study showed that the experimental group that practiced yoga exercises reduced the selected physiological variables than the control group.
