It’s well known that increasing the time spent doing moderate intensity physical activities has wide ranging benefits on health. Guidelines recommend 150 minutes a week of moderate to vigorous physical activity. What about those unable to engage in moderate or vigorous physical activities due to health issues? Could light physical activity work too?

A study by professor Dunlop et al. looked at the effects of physical activity in people¬†with knee osteoarthritis or risk factors for knee osteoarthritis. As well as finding benefits to moderate activity, they found that spending more time doing light intensity physical activities reduced the risk of onset and progression of disability due to osteoarthritis. They concluded that “an increase in daily physical activity time may reduce the risk of disability, even if the intensity of that additional activity is not increased.”
