A major new paper in The Lancet shows that adding 5 min/day of activity, or reducing sitting by ~30 mins can prevent a substantial proportion of deaths. Increasing PA by even a little bit will therefore be a huge win for public health. #exercise #physicalactivity www.thelancet.com/journals/lan...

Deaths potentially averted by small changes in physical activity and sedentary time: an individual participant data meta-analysis of prospective cohort studies

Small and realistic increases in MVPA of 5 min/day might prevent up to 6% of all deaths in a high-risk approach and 10% of all deaths in population-based approach. Reducing sedentary time by 30 min/da...
