Artificial Gravity as a Countermeasure to the Cardiovascular Deconditioning of Spaceflight: Gender Perspectives [PDF]
Frontiers in Physiology, 2018 Space flight-induced physiological deconditioning resulting from decreased gravitational input, decreased plasma volume, and disruption of regulatory mechanisms is a significant problem in returning astronauts as well as in normal aging.

High-Intensity Exercise Mitigates Cardiovascular Deconditioning During Long-Duration Bed Rest [PDF]
Frontiers in Physiology, 2018 Head-down-tilt bed rest (HDT) mimics the changes in hemodynamics and autonomic cardiovascular control induced by weightlessness. However, the time course and reciprocal interplay of these adaptations, and the effective exercise protocol as a ...

Cardiovascular deconditioning and impact of artificial gravity during 60-day head-down bed rest—Insights from 4D flow cardiac MRI [PDF]
Frontiers in Physiology, 2022 Microgravity has deleterious effects on the cardiovascular system. We evaluated some parameters of blood flow and vascular stiffness during 60 days of simulated microgravity in head-down tilt (HDT) bed rest.

Multi-System Deconditioning in 3-Day Dry Immersion without Daily Raise
Frontiers in Physiology, 2017 Dry immersion (DI) is a Russian-developed, ground-based model to study the physiological effects of microgravity. It accurately reproduces environmental conditions of weightlessness, such as enhanced physical inactivity, suppression of hydrostatic ...

A cardiovascular-motor axis framework for perfusion-mediated motor impairment [PDF]
International Journal of Cardiology: Heart & VasculatureCardiovascular disease is the leading cause of death worldwide, and among survivors of heart failure, peripheral arterial disease, valvular disease, and atrial fibrillation many develop motor impairment: weakness, slow gait, sarcopenia, frailty.

The application of artificial gravity in medicine and space
Frontiers in Physiology, 2022 Gravity plays a crucial role in physiology. The lack of gravity, like in long duration spaceflight missions, cause pathologies in e.g., the musculoskeletal system, cardiovascular deconditioning, immune system deprivation or brain abnormalities, to just ...
