How to build muscle as age tears it down
Tehran (KNA) - If you are in your 40s or 50s, chances are that you are starting to notice some changes in your body, including muscle loss and diminishing strength, even if you exercise fairly regularly.
Reduced levels of physical activity, increases in sedentary behavior and doing less intense exercise all play a significant role in age-related muscle loss, known as sarcopenia, which is a leading contributor to frailty and loss of independence associated with aging. Loss of muscle begins in your 30s but gains momentum when you hit 50 and accelerates even more rapidly in your mid-70s.
The good news is that muscle loss and loss of strength can be slowed considerably in most cases and even reversed in some, regardless of age or fitness level. A 1994 study even showed that people could gain muscle in their late 90s.
The most important intervention against muscle loss is strength training, which helps build muscle and support the connection between nerves and muscle cells to maintain the muscle you have. It also helps improve the body's response to dietary protein. Many people, however, don't work out intensely enough to reap the full benefits.
Dietary protein is also important to combat muscle loss, as it provides the building blocks for muscle and stimulates its growth. The quality, quantity and distribution of protein throughout the day becomes more important as you get older. Unfortunately, this is often the age when protein intake decreases, which can accelerate sarcopenia.
