'''Dynamic apnea''' is a discipline of [[freediving]] where the diver moves horizontally under water, attempting to cover the greatest possible distance. This can be done with or without the use of fins.

Dynamic apnea is one of the eight official disciplines of [[AIDA International]], the worldwide federation for breath-hold diving. The discipline requires a combination of physical strength, technique, and efficient oxygen use.  
'''Dynamic apnea''' is a discipline of [[freediving]] where the diver aims to cover the maximum horizontal distance underwater on a single breath. It is one of the competitive disciplines in freediving, governed by organizations such as [[AIDA International]] and [[CMAS]].


In dynamic apnea, the diver starts from the surface of the water, takes a deep breath, and dives under the water. The diver then swims horizontally under the water for as long as they can hold their breath, covering as much distance as possible. The dive ends when the diver surfaces and gives a signal to the judges.

Dynamic apnea is divided into two main categories:


There are two categories of dynamic apnea: Dynamic With Fins (DYN) and Dynamic No Fins (DNF). In DYN, divers use a monofin or bi-fins to propel themselves through the water. In DNF, divers use a modified breaststroke technique.
* '''[[Dynamic Apnea with Fins]] (DYN)''': In this category, divers use fins or a monofin to propel themselves through the water.
* '''[[Dynamic Apnea without Fins]] (DNF)''': In this category, divers rely solely on their body movements, such as the breaststroke, to move through the water.

== Physiology ==
During dynamic apnea, the diver holds their breath while swimming underwater. This activity can lead to [[hypoxia]] (low oxygen levels) and [[hypercapnia]] (high carbon dioxide levels), which are significant risks associated with the sport. Divers train to increase their [[lung capacity]] and improve their [[breath-hold]] times.


In dynamic apnea, divers use various techniques to maximize their performance. These include:
== Safety ==
Safety is paramount in dynamic apnea. Divers should always have a trained safety diver present and follow strict protocols to prevent [[blackout (swimming)]] and other risks. Proper training and gradual progression in distance and time are essential to minimize risks.


* '''[[Breath-holding techniques]]''': Divers use specific breathing techniques before the dive to maximize their oxygen intake and during the dive to conserve oxygen.
== Training ==
* '''[[Swimming techniques]]''': In DYN, divers use a dolphin kick technique with a monofin or a flutter kick with bi-fins. In DNF, divers use a modified breaststroke technique.
Training for dynamic apnea involves improving [[cardiovascular fitness]], [[breath-hold]] techniques, and [[swimming efficiency]]. Divers often practice [[static apnea]] to increase their breath-hold capacity and work on [[equalization]] techniques to manage pressure changes.
* '''[[Streamlining]]''': Divers try to reduce drag by keeping their body in a straight line and minimizing unnecessary movements.

Dynamic apnea competitions are held worldwide, with athletes competing to achieve the longest distance. Records are maintained by organizations such as [[AIDA International]] and [[CMAS]].
The world records for dynamic apnea are recognized by AIDA International. As of 2021, the men's world record for DYN is 300 meters, held by [[Mateusz Malina]] of Poland. The women's world record for DYN is 243 meters, held by [[Magdalena Solich-Talanda]] of Poland.
 
The men's world record for DNF is 244 meters, held by Mateusz Malina of Poland. The women's world record for DNF is 191 meters, held by [[Natalia Molchanova]] of Russia.

Dynamic apnea is a discipline of freediving where the diver aims to cover the maximum horizontal distance underwater on a single breath. It is one of the competitive disciplines in freediving, governed by organizations such as AIDA International and CMAS.

Types[edit]

Dynamic apnea is divided into two main categories:

  • Dynamic Apnea with Fins (DYN): In this category, divers use fins or a monofin to propel themselves through the water.
  • Dynamic Apnea without Fins (DNF): In this category, divers rely solely on their body movements, such as the breaststroke, to move through the water.

Physiology[edit]

During dynamic apnea, the diver holds their breath while swimming underwater. This activity can lead to hypoxia (low oxygen levels) and hypercapnia (high carbon dioxide levels), which are significant risks associated with the sport. Divers train to increase their lung capacity and improve their breath-hold times.

Safety[edit]

Safety is paramount in dynamic apnea. Divers should always have a trained safety diver present and follow strict protocols to prevent blackout (swimming) and other risks. Proper training and gradual progression in distance and time are essential to minimize risks.

Training[edit]

Training for dynamic apnea involves improving cardiovascular fitness, breath-hold techniques, and swimming efficiency. Divers often practice static apnea to increase their breath-hold capacity and work on equalization techniques to manage pressure changes.

Competitions[edit]

Dynamic apnea competitions are held worldwide, with athletes competing to achieve the longest distance. Records are maintained by organizations such as AIDA International and CMAS.
