Identification, objectification, and determination of performance criteria for elite soccer players. Aim: Identification of key point indicators (KPI) of young soccer players with a focus on objectifying and determining the possibility of achieving the highest level of performance. Methods: The study included 157 soccer players, who were then divided into five age groups (U21, U19, U18, U17 and U16) and three performance groups (Elite - 1st league players, Sub-elite - 2nd league players, Amateur - 3rd league and lower performance levels players). Within laboratory diagnostics, the following areas were evaluated: body composition (bioimpedance method), postural stability (using pressure plates), explosive power of the lower limbs (three types of vertical jumps), strength and power of knee extensors and flexors (using isokinetic dynamometry) and the value of the maximum aerobic capacity VO2max (using the pulmonary ventilation exercise test). Within the field diagnostics, the areas of acceleration time (sprint at 5 and 10 m), maximum speed (sprint at 20 m flight), time in the test of change of direction (Agility 505 test and K-test) and values of endurance ability (Yo- Yo intermittent recovery test level 1 and 2). The diagnosed data were then processed in the statistical program RStudio® (USA) using...
