One of the most dangerous aspects of aging is losing strength and muscle mass. Our muscles help us control our bodies and increase our resiliency. The medical term for age-related loss of muscle mass is called Sarcopenia.
While some of this decline in strength is inevitable, there is a lot that individuals can do to maximize their muscle mass and preserve their performance.
The mild onset of Sarcopenia begins sometime between the mid-thirties and the early forties, but lifestyle and genes play a massive role in how the condition manifests. The rate of muscle loss speeds up by around one or two percent per year during the fifties.
The concept of use-it-or-lose-it also applies. If you aren't working out and staying active, the rate of strength decline becomes exacerbated, and it gets harder and harder to restore and build muscle.
By a person's seventies, they may have lost as much as half of their maximum muscle mass due to age-related decline. Males have more problems with Sarcopenia than females—current data suggests that men are 13 times more likely than women to struggle with Sarcopenia at a given age.
