Dynamic apnea is a form of breath-holding practiced in freediving, where individuals swim underwater without breathing. The goal is to cover the maximum distance while holding one's breath, relying on physical fitness and technique. This activity emphasizes the importance of proper training and safety measures to prevent accidents. During dynamic apnea, divers use a streamlined position to minimize resistance and conserve energy. It is often performed in a pool, allowing for controlled environments and safety protocols. Freediving competitions may include dynamic apnea events, showcasing the skills and endurance of participants while adhering to strict guidelines.
