1.Protein contributes to the growth and maintenance of muscle mass.
2.Carbohydrates contribute to the recovery of normal muscle function (contraction) after highly intensive and/or long-lasting physical exercise leading to muscle fatigue and the depletion of glycogen stores in skeletal muscle. This beneficial effect is obtained with the consumption of carbohydrates, from all sources, at a total intake of 4g per kg body weight, at doses, within the first 4 hours, and no later than 6 hours, following highly intensive and/or long-lasting physical exercise leading to muscle fatigue and the depletion of glycogen stores in skeletal muscle.
