  Vertical jump training is a fundamental method for the physical conditioning of athletes. The synergy of motor skills exhibited during such movements substantially contributes to achieving motor acts and actions with higher performance indices. In football, vertical jumping, like other specific factors, is an essential element that can determine the outcome of a match. Football players need to be physically prepared to handle any complex situations that may arise during a game.

  Our study aims to evaluate the impact of plyometric training on vertical jump height performance in young football players.

  A total of 16 subjects, U11 football players, were randomly assigned equally into a PL group (N=8), which followed a plyometric training routine for 6 weeks, and a control group (N=8), which followed the routines set by the club team's coach. They were evaluated in two phases – an initial and a final phase – using Optojump testing equipment. The results obtained were compared using statistical and mathematical methods of descriptive analysis, the Shapiro-Wilk test for normality distribution, and the Independent Samples T-test.

  Additionally, Levene's test was used to analyze the type of variances in the distributions.

  Our study confirmed that a customized plyometric training routine can significantly improve vertical jump performance, considering age-specific characteristics.

  Our investigations suggest that integrating this type of training into the subjects' routines can bring significant benefits to the development of motor skills, specifically to young football players, offering exciting perspectives for optimizing their performance in the long term.

                                                      

• THE EXAMINATION OF EXPLOSIVE LEG STRENGTH IN VOLLEYBALL

  The goal of the volleyball game is for players to get the ball over the net to the opposite side, which they do by jumping up to score. The effectiveness of the jumps is mainly a function of the leg's acceleration. This ability also appears in executing tasks following a deep center of gravity defense. Our study primarily aims to collect tests to measure the rapid strength of legs and predict expected performance. Furthermore, we evaluate the reliability of the tests by reviewing studies analyzing the vertical jump of volleyball players. We grouped the tests into two main categories. We have processed laboratory tests (e.g., force plate, contact mat) and their associated motion analysis software and court tests (e.g., standing long jump, wall touch method). Combining the two groups of tests is essential to obtain relevant results.
