The government has urged Britons to ensure they take vigorous exercise on a regular basis, amid concerns many adults are leaving themselves at risk of developing serious conditions in later life.
According to the Daily Telegraph, the Department of Health had previously recommended half an hour of physical activity five days a week, but now believes more strenuous activity can reduce the likelihood of illnesses.
Healthcare chiefs now advise 19 to 64-year-olds to participate in two-and-a-half hours of "moderate to vigorous intensity" exercise each week and specifically suggested pursuits including swimming, volleyball and basketball.
England's chief medical officer Dame Sally Davies commented that over 60 per cent of UK adults are not sufficiently active and claimed the latest advice had been drawn up taking up-to-date scientific research into account.
Last week, a study published in the British Medical Journal pointed to a possible link between sedentary lifestyles and an increased risk of pulmonary embolism.
