Free-diving
Free-diving is an aquatic sport, considered an extreme sport, in which divers attempt to reach great depths unassisted by breathing apparatus.
The world record for the "No Limits" category of competitive free diving is held by French diver Loic Leferme. On 20 October 2002 he dove to a depth of 162m (531.4 feet), surpassing the previous record by 2 meters. The current woman's record is held by Tanya Streeter, who dove to 160m (524.8 feet) on 17 August 2002. The unofficial records are held by the late Audrey Mestre (166m), and her husband 1988 Luc Besson film Le Grand bleu (The Big Blue).
Physiology of Free-diving
The human body has several adaptations under diving conditions, which stem from mammalian diving reflex. These adaptations enable the human body to endure depth and lack of oxygen far beyond what one would expect. The romantic explanation is given by the anthropologists' aquatic ape theory
These are the adaptations human body have under water and high pressure.
