The purpose of the study was to examine the effects of six weeks of circuit training on selected motor fitness variables among male kabaddi players. Thirty male kabaddi players aged between 18 and 25 years were randomly selected from affiliated colleges in Tamil Nadu and divided into two equal groups, namely an experimental group (n = 15) and a control group (n = 15). The experimental group underwent circuit training for six weeks, five days per week, whereas the control group continued their regular routine activities without additional training. The selected motor fitness variables were speed, agility, explosive power, and muscular endurance. The variables were assessed using the 50-meter dash, shuttle run, standing broad jump, and sit-up test respectively. The collected data were analyzed using mean, standard deviation, paired sample t-test, independent sample t-test, and Analysis of Covariance (ANCOVA). The results revealed significant improvement in speed, agility, explosive power, and muscular endurance among the experimental group when compared to the control group at the 0.05 level of significance. The findings indicate that circuit training is an effective conditioning method for improving motor fitness performance among kabaddi players.
