Brisk exercise can halve the risk of heart attacks
Brisk walks can reduce the risk of a heart attack or stroke by half, new research has found.
However, scientists believe that it is actually the intensity rather than the duration of the exercise that counts while an hour's daily walk makes little difference.
The research was published in the online health journal 'BMJ Open'. The study looked at the health of over 10,000 Danish men and women between the ages of 21 and 98, who were monitored for 10 years.
Maureen Talbot, who is a senior cardiac nurse at the British Heart Foundation, said: "This study reminds us that it is only physical activities that leave us feeling warm or breathing more heavily that are good for our health."
