A new, large-cohort study led by the University of Oxford used accelerometers (wrist-worn devices) to accurately record the activity of more than 90,000 participants over a five year period.
The researchers on the study 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.
