Abstract
This study determined the comparative effect of three modes of Plyometrics
training [depth jumping, rebound jumping and horizontal jumping] on leg muscle strength
of untrained University male students. Participants were forty untrained male University
students within the age range of 18-27 years. The randomized pretest-posttest control group
design was adopted. Subjects were randomly assigned to control group, and three
experimental groups based on the types of plyometrics training adopted for the study. The
training programme consisted of twelve weeks of interval training administered three times
a week. Data collected were analyzed using the mean score, standard deviation and range.
Analysis of Covariance [ANCOVA] was used to test for significant differences in the posttest
measures among the treatment and control groups using the pretest score variation as
covariates. Scheffe post hoc analysis was used to determine which of the means were
significantly different. All hypotheses for the study were tested at 0.05 critical level.
Findings revealed that only the depth jumping and rebound jumping training
significantly altered leg muscle strength of subjects (P
