Objective: To determine immediate effect of single session of yoga and aerobic exercise on feeling-state in high school students.

Method: 120 Students age between 15-18 years from different schools in Surat and Bardoli volunteered for the study. They were assigned randomly into 2 groups equally for both yoga and aerobic sessions. Both groups included 60 students each. Group A performed yoga and Group B performed aerobic exercise. The yoga and aerobic exercise training took 30 minutes each to conduct both the sessions. At the start and at the end of the sessions Feeling State Assessment Questionnaire was filled up by the students. All the students participated actively in both the sessions. Pre and post session results were analysed.

Result: Unpaired and paired t-test were used for comparing means between two groups and within groups, respectively. Results were considered to be significant. Result was found significant for within the group. There is improvement in the feeling state assessment score in both aerobic and yoga groups. The more improvement found in yoga group, as pre and post mean difference is more in yoga group as compared to aerobic group.
