The purpose of the study was to find out the effect of plyometric training and circuit training on selected physical and physiological variables among male volleyball players. Twenty four male volleyball players aged between 18 to 25 years were selected randomly. They were divided into two groups (two experimental and one control group) the experimental group I was given plyometric training and experimental group II was given circuit training for six weeks and control group was not allowed to participate in any training programme. Pretest was conducted dependent variables such as speed, muscular endurance, flexibility, agility, explosive strength, vital capacity and anaerobic capacity at the beginning before the experimental treatment and posttest was taken after the experimental treatment. The data were analyzed by applying dependent ‘t’ test and ANCOVA. The results revealed that the plyometric training and circuit training had significantly improved the speed, muscular endurance, flexibility, agility, explosive strength, vital capacity and anaerobic capacity.
