The timeline of underwater diving technology is a chronological list of notable events in the history of the development of underwater diving equipment.With the partial exception of breath-hold diving, the development of underwater diving capacity, scope, and popularity, has been closely linked to available technology, and the physiological constraints of the underwater environment.
There were two additional unusual swimming events (although common at the time): an obstacle swimming course in the Seine river (swimming with the current), and an underwater swimming race. The 4000 m freestyle was won by John Arthur Jarvis in under one hour, the longest Olympic swimming race until the 10k marathon swim was introduced in 2008.
The history of breath-hold diving goes back at least to classical times, and there is evidence of prehistoric hunting and gathering of seafoods that may have involved underwater swimming. Technical advances allowing the provision of breathing gas to a diver underwater at ambient pressure are recent, and self-contained breathing systems ...
By the end of the nineteenth century, two basic templates for scuba, (self-contained underwater breathing apparatus), had emerged: open-circuit scuba where the diver's exhaust is vented directly into the water, and closed-circuit scuba where the diver's unused oxygen is filtered from the carbon dioxide and recirculated.

The butterfly stroke events were not held until 1956. Previous rules permitted the butterfly stroke in breaststroke races. After 1956, when these rules were changed, butterfly became its own stroke entirely. The 800m event was added to the women's programme in 1968; whilst longer, this event was not as far as the men's 1,500m event. This ...
Confédération Mondiale des Activités Subaquatiques (CMAS; known in English as the World Underwater Federation) is an international federation that represents underwater activities in underwater sport and underwater sciences, and oversees an international system of recreational snorkel and scuba diver training and recognition.
The Finswimming World Championships is the peak international event for the underwater sport of finswimming. These are conducted on behalf of the sport's governing body, Confédération Mondiale des Activités Subaquatiques (CMAS) by an affiliated national federation.
Surface finswimming (also known by its acronym, SF) is swimming on the surface of the water using mask, snorkel, and monofins.SF races are held for distances of 50, 100, 200, 400, 800, 1500, 4 × 50 mix relays (2 men's, 2 women's), 4 × 100 relays and 4 × 200 relays (meters) in swimming pools and over various long distances in the open water environment.
