Mezocyklu effect fundamental changes to the game condition with the progressive nature of the load for youth football players

EFFECT OF THE BASIC MEZOCYKLE TO CHANGE THE GAME CONDITION WITH THE PROGRESSIVE LOAD FOR YOUTH FOOTBALL PLAYERS The aim of this work was to find out whether the use of specific fitness acquisition models (Verheijen, Owen) is more effective as the use of a non-specific model (control group) in elite youth U17 soccer players and whether a player can be equally conditioned in a 4-week period cycle (Owen) compared to a 6-week cycle (Verheijen) or a conventional (non-specific) mesocycle. Methods: The sample consisted of 3 groups of 16 players (n = 48; Age = 16,02±0,78; Height = 178,6±9,8; Weight = 69±10,6; ECM/BCM = 0,8±0,13; FFM = 61,4±9,8). 39 players have completed the whole research and were divided into groups EXP1, EXP2 and KON. The EXP1 group underwent a Verheijen (2000) training program, where large interval games (LSG) also appeared. The sond EXP2 group underwent an intervention program according to Owen et. al. (2012). The third group underwent a training mesocycle with a classic model that was a combination of general and non-specific fitness training. This model consisted mainly of runs (non-specific preparation) and large forms of games at the end of practice. This third group functioned as a control group. Laboratory testing always took place in the Human Movement Laboratory (LSM) of the..
