Specific Characteristics of Functional Ensuring of Football Players’ Special Working Capacity at the Stage of Specialized Basic Training

Introduction. The improvement of the special training of U19 football players is based on the implementation of the conversion of general functional training into special structures for the functional support of the players' special working capacity. The general principles are based on the simulation of test modes and corresponding training loads. which correspond to the tempo-rhythmic structure of the athletes' competitive activity. Goal. To determine the characteristics of the functional training of football players of the age category U19 (18-19 years old). Methods. Gas analysis, measurement of blood lactate concentration, CRS & IE test. 18 players aged 18-19 took part in the study. The results. The characteristics of the functional support of the special working capacity of the players of the main team had the corresponding characteristics – x ̅, quartile 75%, the maximum value: in the first series, EqPaCO2 – 2,03, 2,15, 2,26; VO2 – 49,4, 51,6, 54,1 (ml·min-1·kg-1); La – 9,4, 10,8, 11,0 (mmol·l-1); in the second series – EqVCO2 – 34,4, 36,9, 37,3, EqVO2 – 33,1, 35,2, 36,2;, VO2 – 56,1, 58,9, 60,1 (ml·min-1·kg-1), La– 16,8, 17,5, 18,9 (mmol·l-1). Conclusions. The characteristics of EqPaCO2, VO2, La registered as a result of the first series had differences between athletes of group "A" (players of the main team) and group "B" (players of the backup team), respectively - 3.4%, 5.3%, 4.3%. Characteristics EqVCO2, EqVO2, VO2, La registered as a result of the second series – 9,9%, 2,1%, 11,9%, 22,0% (p<0,05). The indicators of the "training impulse" of the players of group "A", respectively, of the players of group "B" are significantly higher in the first series by 10,5%, in the second - by 16,7%. This indicates a reduced level of physiological stress of the main team players.
