If water losses are not replaced then dehydration can occur and even mild dehydration is associated with negative effects on health including impaired cognitive function. Studies in schoolchildren have found that many are arriving at school with a hydration deficit and, once they arrive, [...]
Influence of progressive fluid restriction on mood and physiological markers of dehydration in women
The present study evaluated, using a well-controlled dehydration protocol, the effects of 24 h fluid deprivation (FD) on selected mood and physiological parameters. In the present cross-over study, twenty healthy women (age 25 (se 0·78) years) participated in two randomised sessions: FD-induced dehydration v. a fully hydrated control condition. In the FD period, the last [...]
Total body water and its compartments are not affected by ingesting a moderate dose of caffeine in healthy young adult males.
Acute and chronic caffeine intakes have no impact on hydration status (R.J. Maughan and J. Griffin, J. Hum. Nutr. Diet. 16(6): 411-420, 2003), although no research has been conducted to analyze the effects using dilution techniques on total-body water (TBW) and its compartments. Therefore, the aim of this study was to investigate the effects of [...]
Effects of a competitive wrestling season on body composition, endocrine markers, and anaerobic exercise performance in NCAA collegiate wrestlers.

Eighteen NCAA wrestlers were tested for endocrine markers, body composition, hydration, grip strength, and power on four occasions: prior to pre-season training (T1); after pre-season training 3 days prior to the first seasonal meet (T2); mid-season one [...]
