Objective of the study was devoted to the establishment of the physiological vector of the modified J. Bangsbo sprint test for football. The reliability of information on the development of anaerobic and aerobic energy supply pathways guarantees the validity and stability of the assessment of specific endurance of football players.
Methods and structure of the study. An improved version of the soccer sprint test. Bangsbo provided for the adjustment of the conditions for maximum compliance with game situations. The determination of lactate levels in peripheral blood was carried out by a team doctor using a portable Lactat Scout analyzer from the 3rd to the 5th minute of recovery after the completion of the sprint test. The study involved athletes from the Youth Sports School "Football Academy" of the Krasnodar Territory, as well as members of the national youth teams of the Krasnodar and Rostov regions. The main requirement for inclusion in the group of subjects was that the passport age of football players corresponded to the range ± 0.5 years (16 years – from 15.5 to 16.5 years; 17 years – from 16.5 to 17.5 years; 18 years – from 17.5 to 18.5 years) and had at least 8 years of training experience.
Results and conclusions. Based on the analysis of lactate levels in peripheral blood, the researchers conclude that the adapted sprint test is effective in determining the contribution of both anaerobic and aerobic processes to energy supply at maximum work intensity. The relatively low lactate content recorded after the test in participants of different age groups indicates the suitability of this method for assessing the specifics of the motor activity of football players during the game. This indicates that the test can serve as a tool for analyzing the energy characteristics of football players.
