As our muscles diminish, we become weaker and increase our risk of fractures and broken bones. The word “sarcopenia” specifically refers to a degenerative loss of muscle mass associated with aging. This occurs at a rate of up to 1% per each year after the age of 25.
A team of researchers in Nottingham, U.K., may understand why this occurs. As older people eat, they cannot make muscle as quickly as they could when they were younger. In addition, elderly people become more insulin-resistant and the hormone fails to stop the muscle breakdown that can happen overnight. This is a one-two punch affecting older people. The good news is that muscle breakdown does not need to be an inevitable part of aging.
Exercise, especially weight-bearing exercise, has been shown to help increase strength, muscle tone and muscle mass even among the very old.… Read the restRead the rest
