In the football game there are actions that have a permanent character, changing direction, jumping, stops and sudden starts. The jumping actions meant to head the ball are very important for the aerial game, in the 16 yards box, and not only. Given the fact that the jump has an important role in the development of such actions, a need to transfer some means of training from volleyball to football players are necessary, especially for the vertical jumps. The higher the force of the legs, the faster the player will perform the actions required by the competitive game.  Maximum strength training creates the conditional basis for explosive strength training. The similarities between the two types of strength are so important that for the improvement of the explosive strength the maximum strength training methods are frequently applied.The two types of strength are strongy related to nerve activation, which can be the basis of the transfer capacity from maximal to explosive. For team sports the ability to accelerate quickly is not enough, coordonation is also required.  To what extent the practice of means of jumping, plyometric jumps, influence the athletic/ physical performance of footballers, with an emphasis on solving the proposed tasks, by adopting a complex set of data collection and processing methods whose value and efficiency consists in the combined use of research methods for drawing conclusions.
