The purpose of the study was to find out the Impact of Land Aerobics and Water Exercise on Cardio Respiratory Endurance Performance among college men Students. To attain the purpose Sixty (N=60) College men students were selected. The subjects were selected equally into three groups of 20 each namely; land aerobics group, water aerobics group and control group. Cardiovascular endurance was selected as dependent variable for this study and it was assessed by Cooper’s 12 minutes run/walk test. The training was resisted to 12 weeks and the number of sessions was limited to 3 days per week. The data for pre and post intervention was taken. Independent ‘t’ test showed significant differences (0.05 Level) in Cardiovascular endurance among the groups. Land Aerobics are superior than Water Aerobics in Cardiovascular endurance. The present study demonstrated that differences in Cardiovascular endurance among Land and Water Aerobic and Control group. Land Aerobic Exercise may have potential role of increasing Cardiovascular endurance.
