Ageing and Physiological Change in Muscle

My Health Assistant05 Apr, 2023Health

The age-related changes in muscle result in reduced muscle strength. This process begins at age 30 with a subsequent reduction in strength of 8% per decade. The rate of decrease is similar in men and women and affects muscle strength more in the legs than in the arms. By the age of 70, there is a 20 - 40% decrease in maximal isometric strength which impacts sustainable walking speed.
