No limit to the benefits of exercise in reducing the risk of cardiovascular disease
A new study led by the University of Oxford on over 90,000 participants shows that there is no upper threshold to the benefits of exercise in reducing the risk of cardiovascular disease – ‘every move counts towards better cardiovascular health.’
A new, large-cohort study led by the University of Oxford has used wrist-worn devices to accurately record the activity of over 90,000 participants followed over five years. This found that physical activity is not only associated with lower risk of developing cardiovascular disease, but the greatest benefit is seen for those who are active at the highest level.
Over the five-year follow up period, 3,617 of the participants were diagnosed with cardiovascular disease (3,305 nonfatal and 312 fatal). This included 2,220 men and 1,397 women. In the participants, as the amount of moderate and vigorous physical activity increased, cases of cardiovascular disease decreased, with no threshold where the effects of exercise stopped improving cardiovascular health.
The protective effect of physical activity against cardiovascular disease was:
- 48%-57% for those in the top quarter of all physical activity
- 49%-59% for those in the top quarter of moderate-intensity activity
- 54%-63% for those in the top quarter of vigorous-intensity activity.
Associate Professor Aiden Doherty, from the University of Oxford’s Nuffield Department of Population Health and one of the lead authors of the study, said: ‘This is the largest ever study of device-measured physical activity and cardiovascular disease. It shows that physical activity is probably even more important for the prevention of cardiovascular disease than we previously thought. Our findings lend further weight to the new WHO guidelines on physical activity which recommend at least 150 to 300 minutes of moderate to vigorous aerobic activity per week for all adults’.
