Light-intensity physical activity is linked to lower mortality in older women

You are here


A study published by the American Geriatric Society found that older women who are physical active have a lower mortality rate.  Consequently, the researchers suggest that older women should be actively encouraged to engage in daily light- intensity physical activity. Healthy older adults should at least spend 2.5 hours doing moderate activity per week or 1.25 hours doing vigorous activity, following official guidelines. The study further substantiates the present knowledge that lack of physical activity and prolonged periods of sitting are detrimental to your health. 

Almost 6500 women, aged 63 to 99, participated in the study. The data was gathered using questionnaires, in-home exams, accelerometers and sleep logs.
