Abstract Cardiovascular deconditioning and altered baroreflexes predispose returning astronauts to Orthostatic Intolerance. We assessed 7 astronauts (1 female) before and following long-duration spaceflight (146 ± 43 days) with minimal upright postu

Orthostatic hypotension, leading to cerebral hypoperfusion, can result in postural instability and falls in older adults. We determined the efficacy of a novel, intermittent pneumatic compression system, applying pressure around the lower legs, as a

During transitions in work rate, O2 uptake (VO2) kinetics at the working tissue level might be rate limited by O2 transport and/or by O2 utilization. A computer model with parallel working and non-working tissue compartments, connected to an ideal lu

We tested the hypothesis that 60 days of head-down bed rest (HDBR) would affect cerebrovascular autoregulation and that this change would be correlated with changes in tolerance to the upright posture. Twenty-four healthy women (32 +/- 4 yrs) partici

We have determined the gain of the cardiopulmonary baroreflex (CPBR) by measuring the central venous pressure (CVP) by venous catheter and calculating the total peripheral resistance (TPR) from mean arterial pressure (MAP) by Finometer and cardiac ou

During the WISE-2005 study of 24 women, we observed a reduction (21.6 +/- 0.89%, mean +/- SEM) in cerebral blood flow velocity (CBV) measured by transcranial Doppler ultrasound, following 0.3 mg sublingual nitroglycerin (NG). In parallel, we observed

This investigation set out to determine the effect of 56 days of head-down tilt bed rest (HDBR) and an exercise countermeasure on endothelial dependent and independent vascular function. 24women took part in this study. 8 subjects completed lower bod

Twenty-four (24) healthy women from 25-40 years of age underwent orthostatic tolerance tests consisting of passive tilt and lower body negative pressure before and after completing 60-days of continuous -6 degree head down tilt bed rest (HDBR). Prior

WISE-2005 studied 24 women during a 60-day head down bed rest (HDBR) who look part in an exercise countermeasure (LBNP-treadmill plus flywheel, EX) and no-exercise (No-EX). We conducted a series of experiments to explore changes in cardiovascular fun
