Short bursts of vigorous exercise helps prevent early death, says study

Short spurts of vigorous exercise that get you out of breath are better than longer bouts of gentle exercise when it comes to preventing an early death, according to a study of middle-aged men and women.
Scientists followed more than 200,000 people for six years and found that those who engaged in some kind of vigorous exercise such as jogging or aerobics lived longer on average than those who exercised gently.
The researchers believe the effect was statistically significant, lowering the risk of premature death by between 9 and 13 per cent compared to those who undertook moderate exercise only, such as gentle swimming or household chores.
The findings contradict the basic assumption of current health advice which is that two minutes of moderate exercise is roughly equivalent in terms of health benefits to one minute of vigorous exercise, said the researchers.
