Fluid replacement requirements in soccer

Abstract

Soccer is an endurance sport that consists of moderate activity levels interspersed with intermittent high-intensity bursts, leading to high rates of metabolic heat production. Even when the weather is cold, significant sweat loss will occur, leading to a degree of dehydration which impairs exercise performance. Fluid intake before and during the game will provide water to reduce the degree of dehydration and can also supply carbohydrate to supplement the body's limited carbohydrate stores. Dilute carbohydrate-electrolyte drinks are most effective for rehydration. The optimum formulation will vary between individuals and will also depend on climatic conditions. Players should be encouraged to experiment with fluid intake during training to identify the type of drink and the amount and frequency of drinks that best meet their needs.
