The physiological processes underlying hemodynamic homeostasis can be modulated by
muscle activity and gravitational loading. The effects of leg muscle activity on cardiovascular …

Introduction Physical exercise and gravitational load affect the activity of the cardiovascular
system. How these factors interact with one another is still poorly understood. Here we …

Mechanisms involved in the control of arterial pressure during postural changes were
studied by analysis of the dynamic time course of cardiovascular changes during head-up tilt …

We hypothesized that impaired cardiovascular responses to isometric muscle action
contribute to the cardiovascular deconditioning that occurs after space flight (SF) and head …

Introduction: Tilt tables enable early mobilization of patients by providing verticalization. But
there is a high risk of orthostatic hypotension provoked by verticalization, especially after …

Performing physical exercises is one of the more established countermeasures against
cardiovascular deconditioning during space flights. However, a systematic evaluation of the …

Head-down-tilt bed rest (HDT) mimics the changes in hemodynamics and autonomic
cardiovascular control induced by weightlessness. However, the time course and reciprocal …

Introduction: Robot-assisted tilt table therapy was proposed for early rehabilitation and
mobilization of patients after diseases such as stroke. A robot-assisted tilt table with …

Lower leg muscles are known to be activated during standing. On the other hand, standing
is known to induce orthostatic stress. Our recent work presented that the posture control and …

Our objective was to characterize the responses of heart rate (HR) and arterial blood
pressure (BP) to changes in posture during concomitant dynamic leg exercise. Ten men …
