The idea of aerobic endurance is associated with the way our bodies obtain energy. In simple terms, we could say that this type of resistance is activated when we need oxygen to carry out an activity, for example, running long distances, climbing a high mountain or traveling long distances with the bicycle. There is an opposite resistance, anaerobic, in which a large amount of oxygen is not needed (for example, to perform a short sprint or to lift weights).
To achieve adequate aerobic resistance it is necessary to exercise the body with an aerobic training, which is typical of long-distance runners, cyclists and all those athletes who make prolonged efforts. It must be taken into account that in the practice of exercise in general the two resistances are used, although one predominates more than the other depending on each sport discipline.
A formula to burn calories and cleanse the mind and body
Aerobic exercise is of a medium or low intensity and produces a consumption of carbohydrates and fats in the body to obtain enough energy, for which oxygen is needed. As oxygen is necessary in these exercises, the cardiovascular system is strengthened (with training the effort of the heart decreases).
Benefits of aerobic exercise
In addition to cardiovascular strengthening, coronary vessels are stimulated, the level of body fat is reduced and subcutaneous fat is eliminated in people who are overweight. On the other hand, there is a decrease in blood pressure in hypertensive patients (this causes that medication to regulate blood pressure is not so necessary). Another benefit of aerobic activity is a reduction in bad cholesterol levels in the blood and an increase in good cholesterol levels.

Likewise, the risk of coronary problems is significantly reduced, blood glucose levels are reduced in diabetics and there is an improvement in lung capacity. Finally, there is an improvement in exertion and a benefit in quality of life in general (the digestive process, sleep and mood).
From a biochemical point of view, aerobic exercise generates endorphins in our body. This aspect is of special relevance, since endorphins are molecules generated by our brain and that produce an effect of physical well-being. For this reason, some athletes are “hooked” on aerobic-type physical activity (the endorphins they produce provide them with a state of happiness and when they do not exercise for a while they feel physical discomfort).
