Objective of the study was to rate effects of the six-weeks-long low- and high-intensity plyometric trainings for the lower-limb speed-strength qualities in volleyball players. Subject to the study were 20 volleyball players with at least 6 years-long track records. Upon the prior tests, the sample was randomly split up into two statistically evenly matched Experimental Groups, with EG-1 and EG-2 trained under the high- and low-intensity training models, respectively.
The study data were interpreted as indicative of the both training models being highly beneficial as verified by the progress of the both groups in the lower-limb speed-strength qualities. It is not unusual for the volleyball coaches to face problems when designing and managing the training tools and training intensity levels for the reason that effects of one or another training tool are not always ratable and easily interpretable. However, a coach shall be fully aware of the effects of the training tools and intensity management scenarios to have the training system timely individualized to the player’s progress, qualities, abilities and anthropometrics. Training workloads under the study were rated versus the trainees’ body lengths and masses. It should be noted that the EG-1 and EG-2 training systems were different only in the intensity rates while the contents of the jumping practices were the same in the both groups. The training process management tools tested in this study may be recommended for practical application in the education and training systems applied by amateur and professional volleyball teams since the plyometric exercises are fairly standard, easily managed and performed, widely versatile in their versions and, hence, readily applicable фе every stage of a volleyball training system.

Keywords: volleyball, speed-strength qualities, high-intensity training.
