An overview of how aging affects muscle mass and strength, emphasizing the biological and lifestyle factors involved.
As we age, our bodies undergo various physiological changes that can lead to a natural decline in muscle mass and strength, a phenomenon known as sarcopenia. Starting around the age of 30, individuals can lose approximately 3-5% of muscle mass per decade, which accelerates in the later decades. Factors contributing to this decline include hormonal shifts, reduced physical activity, and changes in nutrition. Understanding these changes is crucial for developing effective strategies to maintain and build muscle after 40, such as resistance training and proper dietary intake rich in protein. Also, incorporating regular physical activity and focusing on strength training can significantly mitigate the effects of aging on muscle health.
Growing old is mandatory, but growing up is optional.
