TL;DR: Top-class soccer players performed more high-intensity running during a game and were better at the Yo-Yo test than moderate professional players; fatigue occurred towards the end of matches as well as temporarily during the game, independently of competitive standard and of team position; defenders covered a shorter distance in high- intensity running than players in other playing positions.

TL;DR: The Yo-Yo intermittent recovery test was a valid measure of fitness performance in soccer and had a high reproducibility and sensitivity, allowing for detailed analysis of the physical capacity of athletes in intermittent sports.

TL;DR: There are major individual differences in the physical demands of players during a game related to physical capacity and tactical role in the team, and these differences should be taken into account when planning the training and nutritional strategies of top-class players, who require a significant energy intake during a week.

TL;DR: Sprint performance is reduced both temporarily during a game and at the end of a soccer game, the latter finding may be explained by low glycogen levels in individual muscle fibers.

TL;DR: It is demonstrated that all players have high HR throughout a competitive game with periods of near-maximal values, the distance covered by HIR during match play is closely related to the physical capacity, and the Yo-Yo intermittent recovery test can be used as an indicator of the physical match performance of elite female players.
