The effects of physical activity in combating obesity, and even in maintaining optimal body composition, have been one of the issues already discussed earlier in this column. However, there are some recent research results that allow us a better understanding of the contribution of physical in the “burn fat “.
|fat burning exercise|
We know that there are two different fuel energy that our muscles use during physical activity: the sugars or carbohydrates , and fats or fatty acids. When we perform any exercise, muscles use a mixture of carbohydrates and fat to produce energy that is transformed into physical work.
However, this mixture varies with the intensity and duration of exercise. In exercise of higher intensity and shorter duration, the predominant carbohydrate as fuel energy. On the other hand, when the exercise intensity is moderate and more longer duration, the predominance becomes the fats . This scientifically established fact allows us to discuss a practical example to illustrate it to important conclusions.
|Running is best fat burn exercise|
Let’s consider an individual who will cover a distance of 5 km. If the distance is traversed running, say at a speed of 10 km / h, the total exercise time is 30 minutes and the calorie expenditure will be equivalent to approximately 300 calories. If the same distance is traveled walking pace, for example 5 km / h and the time is 1 hour and energy expenditure is also 300 calories.
As we see, in both examples the total caloric expenditure is the same. However, there is one important difference: in the first instance 300 calories have been predominantly derived from carbohydrates and in the second case, the same 300 calories would be produced mainly by the burning of fats. The advice to burn fat is slow down and prolong the duration of the exercise.
