Stroke volume during exercise: interaction of environment and hydration.
Euhydrated and dehydrated subjects exercised in a hot and a cold environment with our aim to identify factors that relate to reductions in stroke volume (SV). We hypothesized that reductions in SV with heat stress [...]
Plasma volume changes during and after acute variations of body hydration level in humans.
This study examined plasma volume changes (deltaPV) in humans during periods with or without changes in body hydration: exercise-induced dehydration, heat-induced dehydration and glycerol hyperhydration. Repeated measurements of plasma volume were made after two injections [...]
Urine color, osmolality and specific electrical conductance are not accurate measures of hydration status during postexercise rehydration.
BACKGROUND: The aim of the study was to determine whether urine color, osmolality and specific electrical conductance (SEC) provide an accurate index of hydration status and of fluid requirements during the recovery phase after an [...]
Evaluation of different levels of hydration using a new physiological strain index
A physiological strain index (PSI), based on rectal temperature (Tre) and heart rate (HR), was recently suggested for evaluating heat stress. The purpose of this study was to evaluate the PSI for different combinations of [...]
