During head-down tilt bed rest (HDT) the cardiovascular system is subject to headward fluid shifts. The fluid shift phenomenon is analogous to weightlessness experienced during spaceflight …

Jul 12, 2022 · The purpose of this study was to investigate the effect of prolonged 60-day bed rest on the mechanical performance of the heart using the morphology of seismocardiography (SCG).

Head-down tilt bed rest has become a primary research tool to examine mechanisms and test countermeasures for cardiovascular alterations. There is abundant literature supporting the …

Several cardiac functional parameters, including isovolumic relaxation time (73 ms to 85 ms at day 7) and myocardial performance index, were significantly increased (0.41 to 0.49 by day 7 …

Bed rest and immobilization of the affected leg are recommended to ensure adequate haemostasis at the femoral artierial puncture site so that risk of developing vascular …

Although the effect of physical constrain and bed rest on vascular function has been already investigated, to our knowledge, this is the first study measuring vascular function and its …

Nov 15, 2020 · Sixty days of strict head-down-tilt bed rest elicited cardiovascular deconditioning indicated by increases in resting and upright heart rate with reductions in left ventricular end …

Jul 12, 2022 · The fluid shift phenomenon is analogous to weightlessness experienced during spaceflight microgravity. The purpose of this study was to investigate the effect of prolonged …

Clinically, an abundance of data demonstrates an association between bed rest and anemia18–35. However, there has been debate over whether this might be caused by a …
