An Exploration of the Effect of Knee-to-feet Jumps on Performance

The purpose of this study was to test the effect of knee-to-feet jump training on power and vertical jump height. Twenty-one varsity athletes from power-emphasized sports were paired and randomly placed in the control or experimental group. All subjects completed preand post-tests of vertical jump height, knee-to-feet jump height, and 2 repetition maximum hang clean. The experimental group completed a 6 week program of knee-tofeet jumps. There was no significant difference in vertical jump height or hang clean weight from preto post-test; however, the experimental group significantly improved in knee-to-feet jump height. There was a positive correlation between knee-to-feet jump and vertical jump height indicating knee-to-feet jumps are a potentially useful tool worth further pursuit.
