Glucose Disposal

Due to its role in fat metabolism and muscle protein synthesis, the management of insulin is a key aspect of achieving a lean, muscular physique. High intensity exercise is thought to promote fat loss as it burns more calories and keeps the metabolism elevated for longer after the exercise is completed. However, the results of a new study suggest that high intensity exercise may promote better fat loss by improving insulin function.

One way scientists measure insulin function is via glucose disposal. Muscle tissue is the largest site of blood glucose disposal. People that exercise regularly have muscle cells that are highly sensitive to insulin, and this effect enables more efficient “disposal” of blood glucose into the muscle cell. The end-result is better control of blood sugar, less fat gain and bigger, stronger muscles.

Scientists from the University of Arkansas have recently shown that intense cardio exercise resulted in greater glucose disposal than moderate intensity exercise. Therefore, intense cardio exercise appears to be more effective at promoting healthy insulin function.

What does this mean to you? Taking those carbohydrates to fuel intense workouts appears to be a good idea, especially when combined with protein
