The purpose of the study was to find out the relative effect of resistance training and water exercise on selected physical variables. For this study 30 male students were selected randomly form Schools in Tirunelveli District at random. All the subjects were informed about the nature of the study and their consent was obtained to co-operate till the end of the experimental period. Their age varied 14 to 17 years. The selected subjects is divided in to three groups (N=10) experimental group 1(resistance training) experimental group II (water exercise) and control group. Shoulder strength, arm power, abdominal power and balance were selected as dependent variables, resistance training and water exercises were selected as independent variables for this study. Shoulder strength was measured through push up, arm power were tested through medicine ball throw test, abdominal power was tested through sit up and balances was measured through stroke stand test. The study was based on the groups pre test and post test design. The subject chosen for the study were divided into experimental and control groups of ten each at random. The data collected from the three groups were statistically analyzed for significance the analysis of covariance (ANCOVA) was significances, 0.05 levels of significances was fixed. Whenever the obtained F-ratio found to be significant, the Scheffe’s test was used as Post hoc test to find out the paired mean difference. It was concluded that, there was significant improvement on selected physical variables such as shoulder strength, arm power, abdominal power, balance due to resistance training and water exercise. It also concluded that, there was significant difference among resistance training, water exercise and control groups in the improvement of selected physical variables such as shoulder strength, arm power, abdominal power and balance.
