The mechanisms responsible for the decrease in exercise capacity after bed rest were assessed in 12 apparently healthy men aged 50 +/- 4 years who underwent equilibrium gated blood pool scintigraphy during supine and upright multistage bicycle ergome

The purpose of this study was to determine the effects of bed-rest-induced deconditioning on changes in O2 uptake (VO2) kinetics, O2 deficit, steady-state VO2, and recovery VO2 during the performance of constant-load exercise. Five male subjects (36

Echocardiographic measurements were obtained before and after space flight from 17 members of four shuttle crews. Measurements obtained 1 h after landing (L+0) compared with preflight values (n = 7) demonstrated an increase in heart rate (HR) (16 bea

Ten men (35-49 years old) underwent lower body negative pressure (LBNP) exposures before and after 10 d of continuous 6 degrees head-down bedrest in order to predict the effect of weightlessness on the responsiveness of leg vasculature to an orthosta

Ventilation (VE), CO2 output (VCO2), oxygen uptake (VO2), respiratory exchange ratio (R), and the ventilatory equivalents for VO2 and VCO2 were measured during graded exercise before and after 10 d of continuous bed rest (BR) in the -6 degrees head-d

The purpose of this study was to compare oxygen uptake (VO2), O2 deficit, steady-state VO2, and recovery VO2 during the performance of a constant-load exercise in the supine and upright position. Ten male subjects (36-40 yr) performed one submaximal

Administration of hyperimmune antibody to leukemia L1210 to allogeneic mice inhibited the development of macrophage-mediated immunity to L1210 in those hosts. In contrast to immunized mice, animals pretreated with antibody showed rapid activation of

A major task for space biologists is to try to delineate methods which can be used to predict the degree of cardiovascular deconditioning that given individuals might develop while in space. Toward that end, we have studied a number of different visc

Small sample size (n less than 10) and inappropriate analysis of multivariate data have hindered previous attempts to describe which physiologic and demographic variables are most important in determining how long humans can tolerate acceleration. Da

The effect of repeated weightlessness exposures on maximal aerobic capacity was determined when seven healthy men (36-48 yr) underwent two 10-d bedrest (BR) periods in the -6 degrees headdown position, which were separated by a 14-d recovery period.
