Document Summary
Learn optimal protein guidelines to maintain and improve outcomes in skeletal muscle health. Explain essential vitamins that aid in the maintenance of skeletal muscle health. Loss of muscle mass, strength and function relating to age. In a young healthy adult, there is a greater ratio of muscle mass compared to individuals with sarcopenia. Can begin as early as 40 years old and accelerates to 70 years old. At age 60, males and females have muscle loss of 3% per year. Those who are physically inactive and active can develop sarcopenia. Decrease in hormone levels and protein synthesis. The following diet is insufficient protein consumption (52g) As you get older, you should consume more protein. Whether you gain or loss muscle depends on a balance of protein synthesis and protein breakdown in the muscle. Current rda for general population: 0. 8 g/kg. For older individuals, rda: 1 - 1. 2 g/kg for a 83 kg individual, they should consume 83-100 g.
