Considering that it is unlikely for all individuals to achieve the WHO physical activity recommendation of 150 min of moderate-to-vigorous-intensity physical activity (MVPA) weekly, our data underscore the large impact of realistic and achievable behaviour changes on population health. If the least active 80% of participants had increased MVPA by 5 min/day or reduced sedentary time by 30 min/day, 10% and 7% of all deaths, respectively, might have been avoided during the follow-up period.
Brief bouts of device-measured intermittent lifestyle physical activity and its association with major adverse cardiovascular events and mortality in people who do not exercise: a prospective cohort study. 2026
"25,241 adults...wore an accelerometer on their wrist...mean follow-up duration of 7.9 years, 824 major adverse cardiac events (MACE) and 1111 deaths occurred. Compared with bouts of less than 1 min, mortality risk was lower for bouts of 1-3 min (hazard ratio [HR] 0·66), 3-5 min (HR 0·56), and 5-10 min (HR 0·48)"
