We know we need to exercise. We are often told to be active most days in a week if we want to lose weight or just 20 to 30 mintues 3 x a week for cardiovascular workout.
BUT what’s the BEST way to do it?… do we exercise 1 hour straight? or is it better to have a rest period in between activities to burn fat effectively?
Excerpts from the Study of Dr Goto published in the Journal Of Applied Physiology….
___________________________________________________
This study compared the fat metabolism between “a single bout of prolonged exercise” and “repeated bouts of exercise” of equivalent exercise intensity and total exercise duration. Seven men performed three trials: 1) a single bout of 60-min exercise (Single); 2) two bouts of 30-min exercise, separated by a 20-min rest between exercise bouts (Repeated); and 3) rest. In the Repeated trial, serum free fatty acids (FFA), acetoacetate, and 3-hydroxybutyrate concentrations showed rapid increases (P < 0.05) during a subsequent 20-min rest period. During the second 30-min exercise bout, FFA and epinephrine responses were significantly greater in the Repeated trial than in the Single trial.
The relative contribution of fat oxidation to the energy expenditure showed significantly higher values (P < 0.05) in the Repeated trial than in the Single trial during the recovery period.
These results indicate that repeated bouts of exercise cause enhanced fat metabolism compared with a single bout of prolonged exercise of equivalent total exercise duration.

In simple terms… it’s better to rest in between exercise activity than a single prolonged activity. The rest period most likely made the tissues and body more efficient in burning more fat especially during the repeat exercise after the rest!
Meaning Rest in between activities is a good way to burn more calories and have time to take a breathier in between workouts!
My advise? Exercise for 30 minutes then take a rest for 10 to 15 minutes then take a plunge to more activites again before heading back home….

Thanks for this info Doc. I held the wrong belief. I thought the longer sustained exercise would give me the optimum benefit.
