Men need twice as much exercise as women to lower heart disease risk, study finds

Researchers suggest sex-specific strategies' after analysis of cardiovascular health improvements

Men may need to exercise twice as much as women to achieve the same reduction in coronary heart disease risk, according to researchers, who say healthy living guidelines should take account of the sex differences.

Scientists analysed physical activity records from more than 80,000 people and found that the risk of heart disease fell 30% in women who clocked up 250 minutes of exercise each week. In contrast, men needed to reach 530 minutes, or nearly nine hours, a week to see the same effect.
