Dynamic apnea is a type of freediving where a diver holds their breath while swimming horizontally underwater. This discipline focuses on distance covered without the use of breathing aids, relying solely on the diver's ability to manage their breath and physical endurance. In dynamic apnea, divers often use techniques to optimize their performance, such as proper body positioning and relaxation. Safety is crucial, as the risk of shallow water blackout increases when holding one's breath for extended periods. Training and supervision are essential for those practicing this sport, often involving coaches and safety divers to ensure a secure environment.
