People who approach or are beyond 30 years of age are troubled by muscle issues. While many muscle deterioration studies center on much older people, the moderate decline of muscle tissue in our bodies starts in our 30s, according to new research.
Fortunately, our muscles can regenerate, and with little effort, we can prevent this wastage. Recent research explains how.
How to Prevent Muscle Degeneration
Muscle regeneration or growth after injury involves satellite cells. When the cells divide into another generation of cells, they can either turn into myoblasts or satellite cells. But, when they’re not utilized, the satellite cells go into something called “the energy-saving dormancy.”
William Chen is a cellular biologist who teamed up with researchers from the University of Ottawa to review how those cells function, including endurance exercise researches, strength training, and genetic and molecular studies. The team discovered that the satellite cells are activated through different signaling ways following exercise.
Ignoring exercise causes issues because the satellite cells are affected, similar to all cells, and covered with cellular trash as the natural processes of life wreck them. Even while asleep, when any cellular activity is lowered, keeping themselves in this phase still develops the cellular waste.
Hence, if satellite cells remain asleep for too long, the waste accumulation can damage and stop the cells from replacing and dividing themselves. Even worse, if the satellite cells are not activated in the aging muscles, they can remain in the dormant stage and waste all energy to multiply and divide.
Chen stated: “Physical inactivity becomes more detrimental with age as satellite cells accumulate higher levels of cellular waste and DNA damage during long periods of deep quiescence.” So, offering these cells a regular exercise will remind them to stay active, helping them more to keep their full abilities.
The team explained: “Exercise alone doesn’t prevent all age-related defects in skeletal muscle; it’s better not to get all our hopes high.” Muscle strength is related to the increased quality of life, especially when we start to age. This aspect of satellite cell biology shows only one reason why exercise is essential to keep our body healthy.
