Natação: como nadar mais, sem se cansar

It's natural that, over time, every swimming student will want to swim longer without stopping. After enjoying the pleasure of learning new skills in the water, and embracing the water as another leisure activity, it's normal for students to seek out swimming as a form of physical conditioning for health, aesthetics, etc. For those learning to swim, it's important to understand that acquiring the ability to swim for long periods of time is achieved in three stages: 1st. Technical Stage: This is where the student must strive to acquire swimming skills as correctly as possible, as swimming well means swimming more efficiently (less effort for more movement), and this applies to both sprint and long-distance swimmers. 2nd. Motor Stage: This is where the student, by repeatedly practicing the correct technique, will consolidate it. This consolidation means: a) a high success rate; b) saving effort in both the agonist and antagonist muscles; 3rd. Physiological Stage: In this stage, the systematic practice of swimming induces important physiological changes in the body for the development of endurance: a) benign hypertrophy of the heart, especially of the left ventricle; b) creation of new arterioles, improving the vascularization network of the muscles in general; c) an increase in the number of mitochondria within muscle cells (fibers), optimizing the use of oxygen for muscle work. These stages are not clearly identifiable, as with everything that occurs in living organisms. While the technical stage is concluding, the motor stage has already begun; and while the motor stage is ongoing, the physiological changes have already begun. But everything begins with the acquisition of good technique. Like the Facebook page managed by the author:   / curso-de-nata%c3%a7%c3%a3o-comunit%c3%a1ri...
