Summary:Age-related loss of skeletal muscle mass and function (sarcopenia) reduces functional independence in the elderly and leads to disability. Dietary protein intake is essential for prevention of sarcopenia. Among the essential amino acids in dietary protein, leucine in particular enhances the synthesis of skeletal muscle proteins via mTORC1. In terms of protein intake, attention should be paid to not only total daily intake but also to the amount of protein consumed at each of the three daily meals. Resistance exercise is the only intervention in daily life that can promote significant muscle gain, and adequate protein intake is also essential for maximizing the effects of exercise and promoting muscle gain. Furthermore, since vitamin D insufficiency/deficiency increases the risk of sarcopenia, there is a need to intervene and monitor various types of nutrient status in combination with exercise interventions in the elderly population.
