A new study published in the American Journal of Physiology reveals that 30 minutes of daily training is as effective in shedding the excess kilos as an hour of exercise.
The study was conducted by researchers at University of Copenhagen who recruited 60 men who were "heavy but healthy" and wanted to get into better shape over the next three months.
The researchers divided the participants into two groups with the first group connected to heart rate monitors and calorie counters and asked to exercise for an hour every day while the second group was asked to train for just 30 minutes a day.
The researchers found that those who cycled, ran or rowed for just 30 minutes a day lost two pounds more than those who exercised for an hour daily at the end of three months. "Participants exercising 30 minutes per day burned more calories than they should relative to the training program we set for them. In fact we can see that exercising for a whole hour instead of a half does not provide any additional loss in either body weight or fat", lead researcher Mads Rosenkilde said.
