The purpose of the study was to determine if eight weeks of plyometric training can improve an athlete's agility power and Resting Heart rate. Subjects were divided into two groups, plyometric training and a control group. The plyometric training group performed in an eight week plyometric training program and the control group did not perform any plyometric training techniques. All subjects participated in Illinois Agility Test, standing broad jump test and a Resting heart rate tests both pre and post testing. Univariate ANCOVA were conducted to analyze the change scores (post — pre) in the independent variables by group (training or control) with pre scores as covariates. The Univariate ANCOVA revealed a significant group effect F = 34.77, p = 0.000, for the Illinois agility test measure. For the Standing broad Jump test, a significant group effect F = 27.52, p = 0.000 was also found. The plyometric training group had quicker posttest times compared to the control group for the standing broad jump tests. There is no significant group effect F = 2.41, p = 0.132 was found for the Resting heart rate test, when using the Pre-test values as a covariate.. The plyometric training group slightly reduced pulse rate on the posttest compared to the control group. The results of this study show that plyometric training can be an effective training technique to improve an athlete's agility and explosive power.
