BBC science site has a provocative story on exercise. The gist:
=======================
According to Dr Stuart Gray from the University of Aberdeen's musculoskeletal research programme, a key factor in reducing the likelihood of early death from cardiovascular disease could be high intensity exercise.
"The benefits do seem to be quite dramatic," he says.
He admits, though, that many in the medical establishment are still promoting moderate intensity exercise.
Gray's study has shown that short bursts of activity, such as sprinting or pedalling all-out on an exercise bike for as little as 30 seconds, result in the body getting rid of fat in the blood faster than exercising at moderate intensity, such as taking a brisk walk.
And getting rid of fat in the blood is important as it reduces the chances of suffering a heart attack.
