Fluid volume measurements in normal subjects to disclose body hydration during acute bed rest.

Measuring intercompartmental, blood and urinary biochemical parameters during acute bed rest (ABR) and rigorous bed rest (RBR) the aim of this work was to disclose if ABR or RBR could influence significantly more and significantly faster the body hydration level in normal subjects. Studies conducted during pre-bed rest (BR) period of 3-days and during 7-days period of ABR and RBR. Thirty normal male individuals 24.

Fluid volume compartments and biochemical measurements for disclosing fluid depletion during acute and rigorous bed rest in normal subjects.

Rigorous bed rest (RBR) induces fluid depletion, however, little is known about the mechanisms of development of fluid depletion during acute bed rest (ABR). Measuring fluid retention and body hydration parameters, the aim of this study was to establish whether ABR than RBR could depress significantly more fluid retention contributing to greater fluid depletion development. Studies were conducted during pre bed rest (BR) period of three days and during seven days period of ABR and RBR.
