What happens in our body when we exercise?

There's no doubt the practice of physical exercise is essential when maintaining and enjoying good health . In fact, just take a look at the different most important benefits of practicing exercise , to realize this. Of course, as long as it is practiced at an appropriate intensity, taking into account also a series of basic recommendations to take into consideration both before and after carrying out physical activity.

For example, it helps us to take care of our cardiovascular health, reducing the levels of fats in the blood (both cholesterol and triglycerides), accelerates and strengthens our heart, helps us maintain an adequate weight, and is also essential to prevent diseases Nowadays as common as for example is the case of overweight and obesity.


Both sport and the practice of physical exercise itself are essential to generally enjoy good health. In fact, it brings a great variety of benefits that translates into improving our health in a tremendously positive way.

However, although many of the benefits of physical exercise are known, it is true that little is written about what happens or occurs in our body at the time we practice sports.

In this sense, especially for those who practice sports assiduously (wise choice, by the way), surely that at some point you have wondered what happens in your body when you exercise.

In this sense, if every day you tend to practice physical exercise, it is possible that in many moments you have asked an interesting question: what really happens when we exercise ? What is the role of physical activity in our body?

What happens in our body when we practice sports?

When we exercise, the different fat molecules of our body are broken down into fatty acids and glycerin, which pass through the outer walls of the cell and enter the bloodstream to be taken by the muscles.

From these precise moments act as fuel, especially when we perform a physical activity that requires some effort.

The fat cells shrink, and our body looks much slimmer.

On the other hand, it is evident that the practice of physical exercise not only results in a possible loss of fat, and therefore, in a consequent loss of weight. More things also happen in our body, and their effects - and benefits - are widely recognized.


For example, a cardiovascular effect occurs, which will depend in reality on whether it is a type of aerobic or anaerobic exercise. In the case that aerobic exercise is oxygen is used mainly in the metabolic process of our body, so that as the demand for oxygen grows will also increase breathing.

However, if it is a type of anaerobic exercise it is really a type of practice without oxygen.

When doing sports metabolic changes that favor the cardiovascular system also occur , and it is precisely these changes that make the practice of physical exercise so fundamental to, for example, protecting ourselves from common disorders such as diabetes.

This beneficial action is observed in both moderate and intense physical exercise, thus producing an increase in the metabolism of fats, carbohydrates and sugars.

And we observe it precisely because amino acids are used as a source of energy in order to maintain adequate glucose levels, especially when physical exercise is of longer duration.

But, if I am obese, why is it so hard for me to lose fat?

To answer this question we must bear in mind that the fat existing in the abdomen of an obese person could have 3 to 5 times the depth of the thinnest layer of fat of a person with a weight considered normal.


This question would explain mainly why the exercises to have a flat abdomen do not work, if in a certain sense they are not accompanied - in short - with a loss of weight.

In other words, obese people have too many fat cells, which implies a much greater capacity to store it, which makes them have more problems to lose weight than thin ones.
