*Carbohydrates contribute to the restoration of normal muscle function after high-intensity and/or prolonged physical exertion that leads to muscle fatigue and depletion of glycogen stores in skeletal muscle. This benefit is observed when total carbohydrates are consumed at a rate of 4 g per kg of body weight during the first 4–6 hours.
*Protein contributes to the growth and maintenance of muscle mass with regular strength training using free weights.
