In recent years, women's football is becoming more popular also in underdeveloped countries of the world. Despite its increasing visibility and prevalence, it is still not sufficiently scientifically supported in order to clearly define the guidelines for the design of fitness training for women football players. In this diploma, in order to facilitate the planning of the fitness preparation of young footballers, with help of three different types of jumps, we wanted to get an insight into the take-off power of the young footballers, and to find out the differences in some parameters of the take-off power, between the various playing positions (defender, midfielder, attacker) in football. The research was carried out on a sample of 22 footballers, aged between 15 and 17. All players are members of a women's up to 17 football national team. The sample consisted of 8 defenders, 6 midfielders and 8 attackers. Measurements were also performed by the goalkeepers (n = 2), which, due to insufficient abundance for statistical analysis, were excluded from the research. Using the tensiometric plate we measured the parameters of the following jumps: squat jump, countermovement jump, drop jump from height of 20 cm and height of 40 cm. The data of all jumps were analyzed. The results show the parameters of the squat jump (the height of the jump, the start interval power, push off time), countermovement jump (jump height, braking force, transfer of force to the concentric part), drop jump from height of 20 cm and height of 40 cm (jump height, contact time) and the differences between the height of the countermovement jump and the squat jump, that show us the efficiency of the elastic energy. The variance analysis showed, that there are no statistically significant differences in any of the analyzed vertical jumping parameters, between the various playing positions in football.
