purpose to evaluate the effect of ramadan fasting on body water status markers of rugby players at basal condition and following a simulation of rugby sevens match. methods twelve recreational rugby sevens players played three matches: one day before ramadan (before ramadan), at the end of the first week of ramadan (beg-r) and at the end of ramadan (end-r). before and immediately after each mat...

Starvation causes impairment in the urinary concentrating ability. The mechanism of this defect, however, remains unknown. We tested the possibility that food deprivation might affect the expression and activity of aquaporins (AQP1, 2), thereby impairing renal water reabsorption in the kidney. Rats fasted for 24 h exhibited severe polyuria (urine volume increased from 11 before fasting to 29 ml...

OBJECTIVE Water intake alters vasopressin secretion. Recent findings reveal an independent association between plasma copeptin, a surrogate for vasopressin, and risk of diabetes. RESEARCH DESIGN AND METHODS Participants were 3,615 middle-aged men and women, with normal baseline fasting glycemia (FG), who were recruited in a 9-year follow-up study. Odds ratios (ORs) and 95% CIs for the inciden...

Patterns of physiological flexibility in response to fasting are well established, but much less is known about the contribution of water deprivation to the observed effects. We investigated body composition and energy and water budget in three groups of zebra finches: birds with access to food and water, food-deprived birds having access to drinking water and food-and-water-deprived birds. Ani...

We measured rate of oxygen consumption ( 2 O V& ) and body temperatures in 10 king penguins in air and water. 2 O V & was measured during rest and at submaximal and maximal exercise before (fed) and after (fasted) an average fasting duration of 14.4 ± 2.3 days (mean ± 1 SD, range 10-19 days) in air and water. Concurrently, we measured subcutaneous temperature and temperature of the upper (heart...
