*Carbohydrates contribute to the recovery of normal muscle function after highly intensive and/or long-lasting physical exercise leading to muscle fatigue and the depletion of glycogen stores in skeletal muscle. This benefit is observed with an intake of total carbohydrates at 4 g per kg body weight, at doses, within the first 4-6 hours.
