Physical activity in mid-life may help protect joint health during aging Wiley

-

In an Arthritis Care & Research analysis of 6661 participants in the Australian Longitudinal Study on Women's Health, maintaining at least low levels of physical activity throughout middle age was associated with lower prevalence and incidence of joint symptoms later in life.

The potential protective effect of physical activity on joint symptoms was stronger in obese women than in under or normal weight women, and it was not related to menopausal status or use of hormone therapy.
