2. The water environment
Buoyancy thrust and pressure. A body, immersed in a liquid, receives a bottom-up thrust equal to the weight of the displaced liquid volume.

3. Heart and Lungs
Knowing these two vital organs in broad strokes helps us understand how the oxygen in the air we breathe irrigates our bodies and is transformed into energy for our muscles.
1. Equipment
Freediving is an environmental sport that is practiced in the water and, for this reason, requires specific equipment that gives us comfort and safety.

4. The extraordinariness of the human body: the blood shift
When Enzo Maiorca, the father of freediving, announced that he wanted to reach the depth of -50m, there was a French doctor, Cabarrou, who opposed such an attempt, reasoning that at that depth the champion's rib cage would implode.
9. Compensation
With this maneuver, the apneist returns the eardrums to a neutral position, which, due to the external pressure, which reduces the volumes of the air zones of our body, would tend to introflex to the point of injury or rupture if they were not rebalanced. Ambient pressure, which increases with depth, causes a reduction in the volume of the aerial parts of our body (lesson 3), compensating the ears reconstitute the original volumes, keeping the eardrum in a neutral position.
8. Preparation for the freediving test
Before any apnea, whether it is static, dynamic or deep, it is a good idea to take a time where you isolate yourself and relax, breathing in stillness and awareness, detaching your mind as if in a kind of meditation, to clear it of anxieties and stress.
7. Apnea specialty.
In addition to static apnea, which we discussed in Lesson #7, we have DYNAMIC apnea and DEEP apnea.
6. Relaxation
Apnea is a discipline that greatly helps us to know ourselves and whose purpose is to savor sensations of pleasure and well-being in the water. Many factors can create states
10. Safety, nutrition and training
Whether practicing in a confined basin or in the sea, apnea should never be done alone.
5. Breathing
All of us, when we are born, know well what is the right way to breathe. If we observed a small baby resting on the changing table, we would immediately
