Lots of studies are going on all over the world to show the association between duration, intensity of exercise and body weight. Official NHS health guidelines advise that adults should get at least 150 minutes of moderate exercise or 75 minutes of intense exercise weekly and the exercise should be done in such a way, there should not be 2 consecutive exercise free days.
Researchers found that each additional daily minute men or women spent in short bouts of high intensity exercise resulted in a small reduction in their Body Mass Index. According to this study, if a 5 ft 5 inch woman regularly adds a minute of exercise to her daily regime she should weigh almost half a pound less.
Results were similar in men. The study was done on 2202 women and 2309 men in America. Research also found each daily minute of exercise also lowered the risk of obesity in women by 5% and in men by 2%.
Jessie Fan, Professor of family and consumer studies at the University of Utah said: “What we learned is that for preventing weight gain, the intensity of the exercise matters more than the duration.”
