L'int\u00e9r\u00eat pour la plong\u00e9e en apn\u00e9e s'est accru de mani\u00e8re exponentielle au cours de la derni\u00e8re d\u00e9cennie. La plupart des amateurs de sports nautiques ont d\u00e9j\u00e0 retenu leur souffle sous l'eau \u00e0 un moment ou \u00e0 un autre, mais la plupart d'entre eux le font sans formation formelle ou sans \u00eatre conscients des dangers connus, malgr\u00e9 la disponibilit\u00e9 de ces informations qui peuvent sauver des vies. Cependant, lorsqu'elle est pratiqu\u00e9e en toute s\u00e9curit\u00e9, la plong\u00e9e en apn\u00e9e peut \u00eatre une exp\u00e9rience exaltante.<\/p>\n\n\n\n

With the rise in freediving\u2019s popularity across many different water sports comes large numbers of beginners who are seeking formal training. Such training offers attainable physical and mental goals with many benefits for mental and physical health and enhanced self-esteem. It also requires strict adherence to safeguards. Disregarding safety measures can bring serious risks to your lungs and brain and even result in death. Understanding the known risks and taking action to mitigate them are central to successfully enjoying any activity, and freediving is no exception.<\/p>\n\n\n\n

Une formation formelle dispens\u00e9e par un instructeur d'apn\u00e9e certifi\u00e9, que divers organismes de formation proposent, permet d'acqu\u00e9rir les bases de la s\u00e9curit\u00e9 en apn\u00e9e. Le moniteur insistera sur de nombreux concepts vitaux au cours de votre formation. Deux des principes les plus importants et les plus souvent r\u00e9p\u00e9t\u00e9s sont de ne jamais plonger seul en apn\u00e9e et d'\u00e9viter l'hyperventilation avant la plong\u00e9e. <\/p>\n\n\n\n

Once certified, you\u2019ll know how to incorporate strict safety standards into every dive, no matter how trivial they may seem. The dive briefing, which should happen before every breath-hold dive, will include analyzing risks, addressing specific concerns regarding the planned dives, and reviewing breath control, rescue techniques, and resuscitation.<\/p>\n\n\n\n

Breath control is a critical point that some freedivers overlook, but it directly affects your body\u2019s oxygen and carbon dioxide levels. Breathing is an autonomic function of the human body and can reflect internal changes in the body\u2019s state. <\/p>\n\n\n\n

Carbon dioxide is a powerful stimulant for breathing \u2014 our urge to breathe increases when we have excess carbon dioxide. Exercise or breath-holding can increase carbon dioxide and decrease oxygen levels. Lower oxygen levels (hypoxia) provide a much weaker stimulus to breathe but may be the only stimulus if we have lower carbon dioxide levels in our blood. When we hyperventilate, we lower our carbon dioxide levels and remove the powerful, carbon-dioxide-induced urge to breathe. <\/p>\n\n\n\n

\"Conscience
Self-awareness of their own breathing is fundamental to a freediver\u2019s safety. \n\u00a9STEPHEN FRINK<\/figcaption><\/figure>\n<\/div>\n\n\n\n
\n
\"l'importance
One of the most important tenets of breath-hold diving is to never do it alone.\n\u00a9STEPHEN FRINK<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n

How do you know when to come up during a breath-hold dive? The urge to breathe is your preservation mechanism, so carbon dioxide serves as a life-preserving stimulant. Without the urge to breathe, a freediver will not know when to come up for air, even if they become dangerously hypoxic. In addition, your awareness will be compromised once hypoxia sets in, and you can become unconscious while underwater, which may result in drowning if your buddy and the safety team don\u2019t effectively rescue you.<\/p>\n\n\n\n

Oxygen in blood is mainly bound to hemoglobin for transportation, while carbon dioxide is mostly dissolved. When carbon dioxide levels drop, the blood\u2019s chemical properties change. Blood pH rises, which strengthens the bond between hemoglobin and oxygen, resulting in oxygen not being adequately released into vital tissues, particularly the brain. When the brain doesn\u2019t have enough oxygen to sustain normal function, it will attempt to preserve the primary functions \u2014 breathing and heartbeat \u2014 while ceasing others, such as consciousness, thought, and motor control.<\/p>\n\n\n\n

En gardant ces informations \u00e0 l'esprit, les apn\u00e9istes doivent reconna\u00eetre que la conscience de leur respiration est cruciale pour leur s\u00e9curit\u00e9. Nous naissons g\u00e9n\u00e9tiquement cod\u00e9s avec des m\u00e9canismes \u00e9volutifs r\u00e9siduels pour survivre sous l'eau pendant un temps limit\u00e9. L'apn\u00e9e est la pratique qui consiste \u00e0 d\u00e9bloquer ces m\u00e9canismes en toute s\u00e9curit\u00e9, de mani\u00e8re scientifique et holistique. <\/p>\n\n\n\n

Il existe de nombreux sch\u00e9mas respiratoires, dont les deux \u00e9l\u00e9ments les plus importants sont le volume courant et l'hyperventilation. Pour expliquer le volume courant, prenons ces deux exemples : Imaginez votre respiration lorsque vous vous endormez en regardant la t\u00e9l\u00e9vision au lit ou une respiration qui ferait \u00e0 peine vaciller une flamme pr\u00e8s de vos l\u00e8vres.<\/p>\n\n\n\n

Explaining hyperventilation is not as simple. The concise definition is any manipulation of your breathing that drops your carbon dioxide levels. Carbon dioxide is our safety net, so we put ourselves at risk if we eliminate too much of it. Any pattern of breathing that decreases our body\u2019s natural balance of carbon dioxide is considered hyperventilation. Long exhalations, exhaling more volume, and rapid breathing all lower carbon dioxide levels.<\/p>\n\n\n\n

La fa\u00e7on id\u00e9ale de respirer avant une plong\u00e9e en apn\u00e9e est de maintenir le volume courant jusqu'\u00e0 la derni\u00e8re inspiration. Respirer normalement peut \u00eatre plus facile \u00e0 dire qu'\u00e0 faire. L'hyperventilation peut se produire par inadvertance ; vous devez la corriger avant de tenter une plong\u00e9e en apn\u00e9e. <\/p>\n\n\n\n

Il est important de suivre une formation ad\u00e9quate et de pr\u00e9voir un intervalle de surface suffisant pour la r\u00e9cup\u00e9ration entre les plong\u00e9es afin d'optimiser la technique de respiration. Le respect de votre formation et des directives fournies augmentera votre s\u00e9curit\u00e9 et votre plaisir \u00e0 pratiquer cette activit\u00e9.<\/p>\n\n\n\n

En r\u00e9sum\u00e9, n'hyperventilez pas et ayez toujours un compagnon de plong\u00e9e comp\u00e9tent qui vous surveille de pr\u00e8s pendant toute la dur\u00e9e de la plong\u00e9e en piscine ou en apn\u00e9e en eau libre, quelle que soit la profondeur.<\/p>\n\n\n\n
