10 hours a week of vigorous exercise necessary to achieve ‘substantial’ CV protection, researchers say
Adults should perform 3-4 times more moderate-to-vigorous physical activity than currently recommended in common guidelines to substantially lower their CVD risk, researchers say.
In bad news for those who think 150 minutes a week is impressive, Chinese researchers say adults should target 560-610 minutes a week to achieve a 30% reduction in their risk of CVD events: MI, AF, heart failure or stroke.
Their study, published in the British Journal of Sports Medicine this month, used the UK Biobank to link exercise data derived from wrist-mounted accelerometers and cardiorespiratory data from cycle ergometer tests to hospital records of CVD events for 17,088 Britons.
They said meeting the widely recommended goal of 150 minutes of moderate-to-vigorous physical activity (MVPA) a week was associated with an 8-9% lower risk of any CVD event after adjusting for factors such as age, smoking and diet.
