High intensity exercise for less than 3 minutes may be as effective in reducing the risk of heart diseases as a 90 minute run, a new study reveals.
Researchers led by Dr Stuart Gray of Aberdeen University as a group of men between 18 and 35 years of age to do high intensity exercise for 30 seconds on a training bicycle and then rest for four minutes before repeating the exercise for another four times. Another group of volunteers were asked to walk at a brisk pace usually recommended by health experts.
Both the groups were asked to return back on the next day and were given a high-fat breakfast and lunch consisting of bread, mayonnaise and cheese. On testing the blood samples of the volunteers to find how quickly the fat levels fell, the researchers found that those who walked at a brisk pace burnt fat 11 percent faster compared to those who did nothing while those who exercised at high intensity burnt fat 33 percent faster.
"lthough moderate intensity, longer sessions of exercise can help protect the body against CVD, the findings of our study showed that high-intensity shorter intervals of exercise might be a more effective method to improve health and reduce the time commitment to exercise. Our initial findings suggest that this type of exercise session would need to be undertaken on most days of the week to maintain the associated health benefits for the body", Gray said.
