Optimal hydration is important factor to achieve high performance in football. The players should know individual sweating rate.
During the training and/or the game the fluid loss should not exceed 2 % of the player's body weight. If the fluid loss is higher, it is necessary to replace it in the after-load recovery period before the next training or game.
Sports drinks with carbohydrates and minerals increase the ability to recuperate muscle energy stores and hydration to initial resting level. Drinks should always be hypoosmolar.
Recommended quantity of fluids corresponds to 150 % of the body weight loss after the physical load. Acclimation to hot and wet climatic conditions for 1 to 2 weeks prior the expected championships to be held under such conditions is highly recommended.
