Filter by:The influence of relatively small decreases in hydration status have been little studied. On two occasions subjects will be allowed to lose about 0,5% of their body weight and one occasion 300ml of water will be consumed. Functional MRI will be used to monitor brain functioning when performing a mental arithmetic task. Heart rate variability will be monitored and related to differences in brain functioning when water has and has not been drunk
The aim of this study is to determine whether drinking plain water when mildly dehydrated benefits cognitive performance and mood. Volunteers undergo a dehydration protocol designed to result in minor dehydration. While some participants receive two 150ml drinks of water others do not. Differences in cognitive functioning are assessed.
The purpose of this study is to investigate the influence of a nighttime feeding on next morning running performance, hydration status, and exercise metabolism in female endurance athletes. Specifically, the effect of a chocolate milk beverage will be examined versus a non-nutritive, flavor-matched placebo. The investigators hypothesize that the nighttime consumption of chocolate milk, a whole food complex, will result in improved next morning running performance versus placebo. Secondarily, the investigators hypothesize that any potential positive performance outcomes from the chocolate milk treatment may be due to an enhanced pre-exercise hydration status or improved exercise metabolism.
When subjected to fluid loss or fluid deficiency irrespective of disease or environmental factors it is discussed how to rehydrate or how to hydrate prophylactic. In medical care it is common to give infusions. However it has increasingly become common to hydrate the patient through the mouth even early after bowel surgery. Moreover it is more simple to provide energy the natural way. Which fluid to give, depends on several factors such as possibility to drink, the volume and emptying of the stomach as well as the fluid absorption in the bowel. The provided fluid can also influence this process depending on temperature, osmolality/tonicity and composition (carbohydrates or salts). In this study we wish to study the speed with which the provided fluid is absorbed by the bowels and how fast the fluid is distributed to the different body compartments depending on it's composition. The three fluids will be either tap water, high sodium chloride and a carbohydrate rich fluid.
