The need to keep muscles healthy
Physical exercise helps to prevent the loss of muscle mass associated with aging. Sarcopenia is the loss of muscle mass, muscle strength and function (1). When sarcopenia progresses due to a sedentary lifestyle and poor nutrition, the quality of life is affected. The risk of falls, fractures and hospitalizations increases. Falls in seniors lead to greater healthcare cost; millions of dollars are spent every year in America due to falls (2). Strong muscles are crucial to support the health of bones. (The need to keep bones healthy will be the focus of a future entry). Sarcopenia is associated with chronic inflammation. The good news is that physical exercise can counter the effects of inflammation on muscle. A new study published by Science Advances found that exercise helps muscle cells to counter chronic inflammation (3). Researchers at Duke University used muscle cells in the laboratory to investigate this. They exposed muscle cells to chronic inflammation by u...
