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 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.
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 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 ...
The Centers for Disease Control and Prevention (CDC) recommends swimming lessons for children from 1–4, along with other precautionary measures to prevent drowning. [4] In 2010, the American Academy of Pediatrics reversed its previous position in which it had disapproved of lessons before age 4, indicating that the evidence no longer supported an advisory against early swimming lessons.
Scientists race against time and rising tides to study prehistoric settlements now submerged by the North and Baltic seas, before wind farms alter the landscape
