The purpose of this present study was to investigate the impact of shallow and deep water aerobic exercises on vo2 max protocol among college men students. To achieve this purpose of the study forty five (N=45) college men students were selected from G.H.G Khalsa College Gurusar Sadhar Ludhiana. The subject’s age ranges from 17 to 23 years. The selected subject were divided into three equal groups consists of fifteen subject each namely two experimental groups and control group from college students. The experimental group I underwent shallow water aerobic exercise group (SWAG) and experimental group II underwent deep water aerobic exercise group (DWAG) programme for six weeks. The control group was not taking part in any exercise during the course of the study. The dependent variable selected for the study were vo2 Max measure by Cooper’s formulae was used and accordingly Cooper’s 12 Minutes Run / Walk Test.Pre-test was taken before the exercise period and post- test was measured immediately after the six weeks exercise period. The data collected from the three groups were statistically analyzed for significance, the analysis of covariance (ANCOVA) was used and the F ratio was found out. The Scheffe’s test is applied as post-hoc test to determine the paired mean differences. The level of significance will be fixed at .05 level of confidence for all the cases.
