The purpose of this study was to examine the efficiency of plyometric exercises on adolescent female volleyballers. To compare the developments of jumping performance between groups we selected two experimental groups (plyometric training and concentric training) and one control group. Each group was composed of 12 volunteer female volleyball players between 15 and 16 years old. All participant groups executed a counter movement jump, static jump with extra loads, drop jump, continuous contact mat jump, and standing long jump tests before and after a 15-week training session. With the exception of the counter movement jump, both experimental groups showed positive and statistically reliable development in vertical jumps and standing long jumps (p < .001). There was no statistically significant difference between the first and postjump tests for the control group. Both training programs had an effect on the growth of some major motor abilities, typical for volleyball play, after 15 weeks of training. This offers the possibility that the type of training can result in greater effectiveness of the training process, saving time, neuromuscular energy, and better results in developing and refining the general physical abilities of growing volleyball players.
