Temporary fatigue during a game
Fatigue at the end of a game
Impaired performance in the initial phase of the second half
Elite players typically cover a total distance of 9-12Km during a game (Bangsbo, 1994)
An international top-class player performs approximately 1350 activities during a game, including about 220 runs at high speed (Mohr et al, 2003a)
This presentation discusses fatigue during a game and the physiological mechanisms that may impair a player’s physical performance
The physiological mechanisms responsible for fatigue appear to change during different periods of a match.
Temporary fatigue may be related to disturbed muscle ion homeostasis. Impaired exercise ability in the first few minutes after half-time could be explained by a markedly lowered muscle temperature at the start of the second half.
The decrement in the last stage of a game may be caused by a depletion of muscle glycogen in individual fibres, and under thermal stress conditions also dehydration and the concomitant hyperthermia.
