Energy balance

Dehydration of 2% body weight loss impairs football performance, and players should aim to prevent this loss by consuming 5-7ml/kg of fluid 2-4 hours before the match.

To avoid performance drops, do not lose more than 2% of your body weight through sweat. Start hydrating 2-4 hours before kickoff by drinking 5-7ml of water for every kg of your body weight. Check your urine color; it should be light yellow. If it's dark, drink more.
