The enzymes present within the mitochondria help in burning fat and reserve the glucose stores within the body. This results in a longer presence of glucose within the body that in turn provides energy for a long time. Studies have shown that athletes who engage in aerobic training have about 200 % more mitochondria compared to those who perform other forms of exercises (Heiden). A recent study conducted by the Duke University Medical Center has further reinstated that aerobic exercises are more efficient in burning belly or abdominal fat as compared to other exercises such as resistance training. This fatty layer which is present deep within the abdominal cavity and between internal organs has for long been associated with an increased risk of cardiac problems, diabetes and cancer. Aerobic exercise was found to burn more calories and in the study it burnt more than 67% which was more compared to that obtained through resistance training. The amount of fat burnt depended on the intensity of aerobic exercise as those with low intensity took more time to break down the unhealthy fat compared to high intensity exercises. In addition, the study also found that aerobic training helped in insulin resistance during fasting, reducing the production of enzymes by the liver and triglyceride levels in the blood (Aerobic Exercise Bests Resistance Training). However, other forms of exercises such as weight training, sprinting and even sleeping have been shown to burn overall calories similar to aerobic training. However, burning of the excess fat within the body is majorly achieved through aerobic exercises.
