Effect of Isolated and Combined Strength and Endurance Training on Cardio Respiratory Endurance of Kho Kho Players

The purpose of the study is to analyze the effect of isolated and combined strength and endurance training on cardio respiratory endurance of kho kho players. To achieve the purpose of this study, sixty men kho kho players studying in various colleges affiliated to Acharya Nagarjuna University, Nagarjuna Nagar, Guntur, Andhra Pradesh, India during the academic year 2014-2015 was selected as subjects. The subjects were selected in the age group of 18 to 22 years and they were randomly assigned into four equal groups of 15 each. Experimental group-I performed strength training, experimental group-II performed endurance training, experimental group-III performed combined strength and endurance training and group-IV was acted as control. The cardio respiratory endurance was selected as dependent variable. The research design of the study was random group design. The data collected from the experimental and control groups on selected dependent variable was statistically analyzed by paired‘t’ test to find out the significant differences if any between the pre and post test. Further, percentage of changes was calculated to find out the chances in selected dependent variables due to the impact of experimental treatment. In order to nullify the initial mean differences the data collected from the four groups prior to and post experimentation on selected dependent variables were statistically analyzed to find out the significant difference if any, by applying the analysis of covariance (ANCOVA). Since, four groups were involved, whenever the obtained ‘F’ ratio value in the adjusted post test mean was found to be significant, the Scheffe’s test was applied as post hoc test to determine the paired mean differences, if any. It is concluded that due to the effect of isolated endurance training and combined strength and endurance training the cardio respiratory endurance of the subjects is significantly improved however, due to the effect of isolated strength training the cardio respiratory endurance of the subjects is not significantly improved. The result of the study also produced 3.36% of improvement due to strength training, 6.89% of improvement due to endurance training and 9.17% of improvement due to combined training.
