MODERATE levels of exercise are often prescribed for people recovering from a heart attack or heart surgery, but pumping up workouts to high-intensity level may also be a safe option, according to a Norwegian study.
"The results of the current study indicate that the risk of a cardiovascular event is low after both high-intensity exercise and moderate-intensity exercise," said Oelvind Rognmo, lead author of the study and a researcher at the Norwegian University of Science and Technology.
Rognmo said there is plenty of evidence that the harder people work out, the more benefit they gain in cardiovascular function. His team wanted to see if heart patients could benefit from high-intensity exercise. The concern for heart patients is that the higher exertion may carry an increased risk of heart malfunction.
The new study tracked 4,846 patients in Norway who racked up a combined total of more than 170,000 hours of aerobic exercise. More than 129,450 hours was spent working out at moderate intensity and the rest was at high intensity.
During the more than 129,000 hours people spent exercising moderately, one person died from cardiac arrest. During more than 46,000 hours of high-intensity workouts, two people had cardiac arrests but survived.
