Freitaucher
Freitaucher, or freediver, is a person who dives underwater without the use of breathing apparatus, relying on breath-hold. Freediving is practiced for recreation, sport, and professional purposes such as scientific research, rescue, or spear-fishing. Techniques emphasize efficient air management, buoyancy control, and safe ascent.
Competitive freediving includes several disciplines: constant weight (CWT) where descent and ascent are made with fins
Training and safety: Acquiring breath-hold tolerance, equalization, and depth technique involves progressive sessions, dry land exercises,
Physiology and equipment: The mammalian dive reflex, lung and chest elasticity, and spleen contraction contribute to
History and notable figures: Freediving has roots in ancient diving cultures. In the 20th century, explorers
