The criteria for the readiness of football players are indicators such as maximum oxygen consumption and physical performance. Functional status of the players is determined in the research laboratory of HCM State Physical Culture Academy. The difference in the structure of the functional readiness of the players with different abilities of different playing roles (goalkeeper, center and wing, central midfield and wing and attack) is revealed. The results of this study show that the greatest level of aerobic performance is characteristic of wing players and midfield players. But, especially important is aerobic performance for the flank, or, the wing players who perform the greatest amount of work on the field. It has been established that the VO2max of wing defenders is in the range from 64.32 to 65.32 ml/min kg-1.
