Method and Procedures
Participants
Forty apparently healthy untrained male undergraduates of the University of Ibadan, Nigeria,
participated in the study. Subjects were volunteers, certified medically and physically fit to take part in
the training programme. They were randomly divided into four groups of 10 participants each. Three
of these groups served as the experimental groups that participated in the depth jumping, rebound
jumping and horizontal jumping exercises, while the fourth was the control group.
