Static apnea
Static Apnea[edit | edit source]
Static apnea is a discipline of freediving where the participant holds their breath underwater for as long as possible while remaining stationary. It is one of the eight disciplines recognized by the International Association for the Development of Apnea (AIDA), which is the worldwide federation for breath-hold diving.
Overview[edit | edit source]
In static apnea, the diver floats on the surface of the water, face down, and attempts to hold their breath for the maximum duration. Unlike other freediving disciplines, static apnea does not involve any movement or swimming, focusing solely on breath-hold duration.
The discipline is often practiced in a pool, but it can also be performed in open water. Competitions are usually held in a controlled environment to ensure the safety of the participants.
Physiology[edit | edit source]
During static apnea, the body undergoes several physiological changes to conserve oxygen and extend the duration of the breath-hold. These include the mammalian dive reflex, which involves a reduction in heart rate (bradycardia), peripheral vasoconstriction, and a shift in blood flow to vital organs such as the brain and heart.
The ability to hold one's breath for extended periods is also influenced by factors such as lung capacity, carbon dioxide tolerance, and mental relaxation techniques.
Training[edit | edit source]
Training for static apnea involves both physical and mental preparation. Physical training includes exercises to increase lung capacity and improve cardiovascular fitness. Mental training focuses on relaxation techniques, visualization, and meditation to help the diver remain calm and reduce oxygen consumption.
Safety is a critical aspect of training, and divers are advised to practice with a buddy or under the supervision of a qualified instructor.
Safety[edit | edit source]
Safety is paramount in static apnea, as prolonged breath-holding can lead to hypoxia and blackout. Divers are trained to recognize the signs of hypoxia and to terminate the breath-hold before reaching a critical point.
Competitions and training sessions are conducted with safety protocols in place, including the presence of safety divers and medical personnel.
