| Purpose. The purpose of this study was to examine the effects of a five week plyometric training program and two weeks of recovery on high school female volleyball players.; Method. A pre-experimental research design was conducted, using a one-group pre-posttest design in which all subjects received the same training. This study consisted of five weeks of training, where subjects performed plyometrics two days, and resistance training one day a week. Then after two weeks of recovery was done, where subjects were asked not to participate in any plyometric activity. An established plyometric protocol was used for training along with a Vertec(TM) to calculate the vertical jump heights of each of the subjects.; Findings. A significance increase was reported between the two testing sessions from pretest to posttest. There was also an additional increase seen in the vertical jump heights from posttest to follow-up test.; Conclusion. Plyometrics and recovery do have an significant effect on the vertical jump heights of high school volleyball players. |
