The aim of this study was to find out the effects of plyometric training and circuit training on selected performance variables of school kho kho players. For this purpose randomly selected 75 school level kho kho players from Andhra Pradesh was selected and the performance variables selected were single chain run and double chain run. The study was formulated as a true random group design consisting of a pre-test and post test. The subjects (N=75) were randomly assigned to three equal groups of twenty five school boys. The groups were designed as experimental group I – plyometric training group, experimental group II Circuit training group and control group respectively. Pre test was conducted for all the 75 subjects on selected performance variables. The experimental groups (plyometric and circuit training) participated in respective training for a period of six weeks. The control group did not participated in any of the training programme. The post test was conducted on the above said dependent variables after a period of six weeks for all the three groups. The obtained data were subjected to statistical analysis using ANCOVA. When significant F values obtained the results were further subjected to post hoc analysis using Scheffee’s confidence interval test. RESULTS adjusted post test means were determined and analysis of covariance was done and the obtained F value 66.95 on single chain run and 101.10 on double chain run were greater than the required value of 3.13 and hence it was accepted that the plyometric training and circuit training, significantly improved the performance variables of kho kho playersd. The post hoc analysis on single chain run and double chain run on the obtained ordered adjusted means proved that there was significant differences existed between control group and plyometric training group and control group and circuit training group. This proved that due to six weeks plyometric training single chain run of the School Kho Kho players improved significantly.While comparing between the two experimental groups, it was found that plyometric training group was significantly better than circuit training group in improving single chain run and double chain run of school kho kho players. CONCLUSIN Based on the results of this study, it was found plyometric training was better than circuit training in improving performance variables of school kho kho players.
