Abstract
In today's aging society, maintaining physical strength in the elderly is crucial to prevent sarcopenia, which affects about 20% of Japanese individuals aged 75-79 and increases mortality and disability risk. Lower estrogen levels are linked to muscle weakness, especially in menopausal women. While resistance exercise is known to help, dietary intake also plays a key role in muscle health. A systematic review of RCTs from 2014-2024 found that supplements like soy, whey protein, HMB, vitamin D, essential amino acids, and Korean mistletoe extract can improve muscle mass, strength, and function in Asian women aged 65 and older. Further research combining nutrients and exercise is needed.
