A heart-rate zone that improves cardiovascular fitness is defined as between 55 and 80 percent of maximum heart rate, according to The American College of Exercise. A less-conditioned individual may see benefits to her heart health at the lower levels of this recommended zone while an athlete needs to work at a higher intensity to improve fitness.
The fat-burning zone occurs at the lower end of the cardio zone—between 55 and 70 percent of maximum heart rate. When working at this intensity, a greater percentage of calories burned comes from stored fat.
Working anywhere within the cardio zone will improve cardio fitness and burn calories. The benefit of working in the fat-burning zone is that you target stored fat and thus encourage weight loss. But, keep in mind, that if you work in a higher zone, you burn a greater amount of calories overall—which is important to weight loss. Although a lower percentage of these calories will come from fat sources, the total number of fat calories burned will likely be the same or greater.
Take, for example, a person who burns calories in a minute walk at a heart rate of 55 percent of maximum. Seventy-five percent of those calories, or 75 calories, may come from fat. However, a person who runs those same 15 minutes and burns calories may burn only 50 percent of those calories from fat, but will burn a total of fat calories in the same amount of time. A study based on 36 relatively fit runners published in the "Journal of Strength and Conditioning Research" in October demonstrated that determination of a person's exact fat-burning zone may only be performed in a laboratory.
In this study, significant overlap between the fat burning and cardio zones existed, indicating that a person working within 60 and 80 percent of maximal heart rate is likely to be maximizing fat oxidation.
