The world record for the "No Limits" category of competitive free diving is held by French diver Loic Leferme. On 30 October 2004 he dived to a depth of 171 m, in Villefranche, Nice, France; surpassing his previous record by 9 meters. The current woman's record is held by Tanya Streeter, who dived to 160 m (524.8 feet) on 17 August 2002. The unofficial records are held by the late Audrey Mestre (166 m), and her husband Francisco “Pipin” Ferreras (170 m). On 30 October 2004, Loic Leferme reached a depth of 171 m in the No Limits category; this new world record has yet to be ratified by AIDA , an international governing body of free-diving.
Competitive free diving is generally broken down into three categories; static, dynamic and depth.
The depth category has four sub-sections:
Women and men's records are recognized in each category.
Free-diving featured heavily in the 1988 Luc Besson film Le Grand bleu ( The Big Blue).
The human body has several adaptations under diving conditions, which stem from mammalian diving reflexSubmerging the face into water causes the mammalian diving reflex which is found in all mammals, but especially in marine mammals as for example whales and seals. This reflex puts the body into energy saving modus to maximize the time that can be spent un. 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'Anthropology (from the Greek word ANTHROPOLOGIA consists of the study of humankind (see genus Homo . It is holistic in two senses: it is concerned with all humans at all times, and with all dimensions of humanity. Central to anthropology is the concept of aquatic ape theory
These are the adaptations human body have under water and high pressure.
