Physical Function: Why Men and Women Age Differently
One of the more intriguing findings in aging research is that men and women do not age in exactly the same way. Women generally live longer than men, yet men often maintain certain aspects of physical function longer into old age. This apparent contradiction highlights the complex relationship between longevity and physical decline. In particular, men tend to retain grip strength, muscle mass, and mobility longer than women. Researchers often use grip strength as a simple measure of overall physical function because it correlates with independence, balance, and the ability to perform everyday tasks. While both men and women experience declining strength with age, men generally begin with greater muscle reserves and often maintain higher levels of strength throughout later life. Muscle mass follows a similar pattern. Beginning in middle age, everyone gradually loses muscle tissue through a process known as sarcopenia. However, women frequently experience a more rapid decline after menop...
