This study investigated the effects of progressive mild dehydration during cycling on whole body substrate oxidation and skeletal muscle metabolism in recreationally active men. Subjects (n=9) cycled for 120 min at ~65% VO2peak (22.7°C, 32% RH) with water to replace sweat losses (HYD) or without fluid (DEH). Blood samples were taken at rest and every [...]

Studies have shown that divers may lose large volumes of body fluids in hot water suit (HWS) dives lasting for four hours or longer, and that this dehydration is mainly caused by sweating. Body fluid balance may be impaired and the diver's alertness and power of judgement could be influenced by such imbalance. The main [...]
