About freediving

Do you know what freediving is?


Imagine that you scored a full chest of air and ... dived into the blue abyss. At first, water tried to push you to the surface, as if hinting that there is no place for a person under water, not his element, alien, dangerous. But you did not succumb to her tricks and not without difficulty overcame the first few meters down. And here you seem to float under water, merging with laughering currents, fish swim by their underwater business, somewhere on the side a colorful coral reef has spread bright spots, and you still fall and fall down ... Where there is only silence and the desired peace, where the ubiquitous sunshine barely penetrates. There, where only the depth and you. You and the depth.



This is freediving


Amazing, giving incomparable sensations, allowing to reveal the most incredible possibilities of the human body.


Kind of sport. Lifestyle. Real adventure


Do you like to dive behind the shells and rapana? This is freediving. Maintain good shape by skirting the pool path? And this, of course, freediving. Do you enjoy reefs and colorful fish at a depth without scuba gear? Yes, yes, freediving.

Freediving is multifaceted, and we invite you to get to know him better.



Freediving - where to start?


Free diving come in different ways. Someone falls in love with him on the stories of friends, someone under the water beckon sea animals. Many come inspired by the iconic film by Luc Besson's “The Blue Abyss”, and the glory and achievements of the legendary Natalia Molchanova lead someone. They come from spearfishing - freediving sibling - from diving, surfing, kiting and other sports. Someone else in childhood held his breath in the bathroom, and now he wants to learn how to do it longer. Someone dived with friends for crayfish and rapana and always dreamed of diving even deeper. Someone wants to learn not to be afraid of water, but someone feels the strength to grow as an instructor over time and teach others to dive safely.


Different paths, different goals, different approaches. One thing unites us all - the desire to dive.


But you heard or read about freediving, and even saw it with your own eyes. And what to do next?

Especially for those who are just starting their freediving path, we wrote step-by-step instructions with possible scenarios.



Step 1 - Choose a freediving training system


There are several of them in the world.

AIDA - Association Internationale Pour Le Developpement De L’apnee

CMAS - Confédération Mondiale des Activités Subaquatiques

Apnea Academy - School of Education

SSI - Scuba Schools International

NDL - National Dive League (Russia)

PADI - Professional Association of Diving Instructors


Among the instructors of the Federation of Freediving are instructors of the system Molchanovs, AIDA, Apnea Academy, SSI. In the near future, we hope that the trainers of other systems will also become members of the Freediving Federation.

To understand how one system differs from another, to feel the nuances of each of them, perhaps, you need to complete at least one course in each method. In addition, you can talk with students from different schools and ask for their opinion.


There are people who initially purposefully go to study using one of the methods, if you are not one of them, we advise you not to choose a training system, but a specific instructor who will teach you everything you need to know and be able to use a freediver. And by what method he will do it, perhaps not so important. A list of Molchanovs instructors can be found on a special page of our site.




Step 2 - Basic Learning - Free Resource Basics


In any system, training begins with a basic course. It can be called differently (in the AIDA system, for example, courses are indicated by stars, waves in the Molchanovs system), but this will always be the foundation, the foundation for the freediver.

We are often asked whether it is necessary to be able to swim in order to practice freediving.


We have cases when people who cannot swim come to the basic course. As a rule, by the end of the course they really start to dive. But! In this case, both you and the instructor will be much more difficult. Be sure to check with the instructor if he is ready to take on a student who cannot swim at all.


At the end of the basic course passes the theoretical exam and the delivery of standards. You can find a detailed program and guidelines here. If all tests are successfully passed, you will receive a first-wave freediver certificate, which will give you the right to attend regular freediving classes.


Step 3 - Regular freediving


Having studied at the basic course and received a certificate, you get the right to attend regular freediving classes at any of the instructors.


Step 4 - Field Depth Courses


Dive with the professionals!



Freediver dictionary


Terms and concepts that any freediver should know.

Bases of diving with breath holding with additions.


Nitrogen narcosis - deep intoxication. Dependency quickly arises.


Apnea - in a medical way: lack of spontaneous breathing.


Dynamic apnea - diving in length with breath holding, caused by various driving motives.


Static apnea - controlled arbitrary breath-holding at rest by completely healthy people.


Acidosis - the shift of the acid-base balance of the body in the direction of increasing acidity. The reason is the accumulation of acidic products of metabolism, and not the use of acidic foods.


Barotrauma - injury caused by pressure drop and the difference in the desire of the individual and the capabilities of the body of the freediver.


Blackout - losing somewhere by the muddler-freediver of his mind while diving.


Hydrostatic pressure is the pressure of the weight of a water column on a fragile air freediver.


Hyperventilation - intense breathing, which exceeds the body's need for oxygen. Leads to the leaching of carbon dioxide and complacency, which is very inappropriate during diving.


Hypercapnia is a high content of carbon dioxide in arterial blood and body tissues. Carbon dioxide is a product of metabolism and is not considered very harmful. In small doses has a beneficial effect on the body. When the dose is exceeded, the central nervous system (CNS) begins to slow down.


Hyperoxia is an increased oxygen content in body tissues. It has a beneficial effect on these tissues. When you exceed the dose, the central nervous system begins to slow down.


Hypoxemia - low oxygen in the blood.



Hypoxia - low oxygen content in the tissues. Also has a beneficial effect on the same tissue, because upon completion of the hypoxic load, recovery processes are activated. And also when the dose is exceeded, the central nervous system begins to slow down. Thus, when diving in depth, the combined effect of these factors (namely, hypoxia, hyperoxia, hypercapnia) leads to a triple beneficial effect. Hooray! Hooray when there is no excess dose of exposure.


Hypocapnia is a low content of carbon dioxide in arterial blood. It has a beneficial effect on the psyche, because I don't want to breathe at all. In this case, the body is introduced into the deepest error.


Hyperthermia - overheating of the body caused by freedivers due to an error in the selection of a wetsuit.


Hypothermia - cooling of the body caused by freedivers due to an error in the selection of a wetsuit.


The dive site is a place where underwater locals communicate with graceful freedivers and clumsy divers.


Decompression illness - a disease that develops as a result of impaired blood circulation, damage to cells and tissues by gas bubbles formed in the blood and tissues with a decrease in pressure. Young freedivers should respect the old freedivers who have accumulated practical knowledge in this area and have shown the right path.


Breathing is a set of processes that ensure the supply of oxygen from atmospheric air into the organism, its use in the biological oxidation of organic substances and the removal of carbon dioxide from the organism. External breathing at the time of diving, including the entry and removal of gases, of course, stops. But tissue breathing, thank God, continues. The value of the life process increases with the desire to breathe. And the search for the meaning of life ceases to torment.


Computer wrist - a device for measuring time and depth of immersion. Not important for recreational freedivers, diving just for fun. But it represents a unique toy for a sports freediver: there is a lot of information on the screen, which overshadows the main thing - the attitude of the world, the world outlook.


Laryngospasm - involuntary contraction of the musculature of the larynx. Rescue reflex for freediver.


Pulmonary volumes of a person. Comparative values ​​of freedivers and non-freedivers:


Respiratory volume is a pulmonary volume that is breathed in or exhaled by a person with quiet breathing. For freedivers, values ​​are less than for non-freedivers, since their body at rest saves as much as possible.


The vital capacity of the lungs is the maximum amount of air exhaled after the deepest breath. Freedivers are well versed in deep breaths.


Residual capacity of the lungs - the volume of air remaining in the lungs after a deep expiration. For freediving divers, the values ​​are lower due to the elasticity of the diaphragm.


The total capacity of the lungs is the volume of air contained in the lungs after the maximum inhalation (sum of vital capacity and residual volume). For freedivers, much depends on this volume, but not everything. Another important area of ​​the body, because if the freediver is large, then a large volume of light will not help.


The mastered depth is the depth into which the freediver dives happily! And in which it is easy and comfortable for him and cozy!


Extreme depth - the maximum available depth. In which the freediver dives like a scout.


Purging - pressure compensation using special techniques (Frenzel and Valsalva maneuvers). What is guided by the depth, when some divers start up, and others slows down, it is not clear.


Dive profile - the speed of the dive and ascent. Beautiful profile - symmetrical. From 0.8 m / s to 1.2 m / s. But if the freediver is not friendly with the ears, it is asymmetric, because dive will have to be quieter, and float faster.


Samba - loss of motor control. Not very nice dance with freediver.


Spirometry is a method for studying respiratory function. The freediver takes pride in this research.


Freediving military - breath-diving with a patriotic purpose.


Freediving conditional - diving in order to increase the functional capabilities of the body to become higher and more beautiful.


Free diving recreational - diving for the purpose of active recreation and environmental awareness. Satisfaction or delight or many other positive emotions experienced recreational freediver.


Freediving applied - diving for the purpose of extracting crabs, shells or any other goodies. As well as useful in life or decorating it all sorts of underwater inhabitants.


Freediving sports - diving in order to realize the maximum individual abilities in a sports result. A little at odds with the philosophy, where is the inner spiritual transformation, if the structural transformations? But musicians also have contests - who are more inspired. And among the scientists of the prize - who is smarter.


The freediver is a diver who knows the «unbearable lightness of being.»
