From this article, Impact of exercise intensity on body fatness and skeletal muscle metabolism, this quote:
“The metabolic adaptations taking place in the skeletal muscle in response to the HIIT program appear to favor the process of lipid oxidation”.
“Despite its lower energy cost, the High Intensity Interval Training (HIIT) program induced a more pronounced reduction in subcutaneous adiposity compared with the ET program. When corrected for the energy cost of training, the decrease in the sum of six subcutaneous skinfolds induced by the HIIT program was ninefold greater than by the endurance training (ET) program”
If you want to get the most for your minimal free time or if you hate to exercise HIIT will burn more calories for the time spent. Calories are burned four ways with this workout:
*After the workout your body burns calories in the process of rebuilding and recovery - especially after HIIT.
*As you become stronger you enhance muscle tone. This burns more calories.
*You burn calories while you exercise.
*As you become stronger your body will add muscle. Muscle is metabolically active. Your resting metabolic rate will rise with the additional muscle.
HIIT is the type of fitness training we do at Austin Personal Training andNew Orleans Fitness Training. The fitness training sessions are infrequent (once or twice a week) and short (20 to 30 minutes), but the sessions are demanding especially in regard to calorie burning. For those who wish to do more ,this strength training program will free up your time to do other types of calorie-burning activities.
