Cardiovascular deconditioning during long-term spaceflight through multiscale modeling. [PDF]
NPJ Microgravity, 2020 Abstract Human spaceflight has been fascinating man for centuries, representing the intangible need to explore the unknown, challenge new frontiers, advance technology, and push scientific boundaries further. A key area of importance is cardiovascular deconditioning, that is, the collection of hemodynamic changes—from blood volume ...

Exercise as a Countermeasure to Microgravity-Induced Deconditioning [PDF]
운동과학PURPOSE This study aimed to comprehensively evaluate the physiological challenges posed by microgravity on the neuromuscular and cardiovascular systems of astronauts and to assess exercise-based countermeasures designed to mitigate these effects during ...

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1998 The effect of cardiovascular deconditioning on baroreflex control of the sympathetic nervous system was evaluated after 14 days of hindlimb unloading (HU) or the control condition. Rats were chronically instrumented with catheters and sympathetic nerve recording electrodes for measurement of mean arterial pressure (MAP) and heart rate (HR) and ...

Cardiovascular deconditioning increases GABA signaling in the nucleus tractus solitarii.
J Neurophysiol, 2022 Gravity influences distribution of blood volume and autonomic function. Microgravity and prolonged bed rest induce cardiovascular deconditioning (CVD). We used hindlimb unloading (HU), a rat analog for bed rest, to investigate CVD-induced neuroplasticity in the brainstem.

Exercise and physiological monitoring in isolated, confined and extreme environments and space analogues: A scoping review. [PDF]
Exp PhysiolAbstract This scoping review synthesized evidence on physical activity/exercise and physiological monitoring in isolated, confined and extreme (ICE) environments, with emphasis on Antarctic missions and space analogues. ICE exposures combine cold stress, confinement, disrupted light–dark cycles and psychosocial strain, which can challenge ...

Running vs. resistance exercise to counteract deconditioning induced by 90-day head-down bedrest
Frontiers in Physiology, 2022 Spaceflight is associated with enhanced inactivity, resulting in muscular and cardiovascular deconditioning. Although physical exercise is commonly used as a countermeasure, separate applications of running and resistive exercise modalities have never ...

Frontiers in Cardiovascular Medicine, 2023 Impaired cardiovascular autonomic control following space flight or immobilization may limit the ability to cope with additional hemodynamic stimuli. Head-down tilt bedrest is an established terrestrial analog for space flight and offers the opportunity ...

The FASEB Journal, 2020 Cardiovascular deconditioning (CVD) due to bedrest, inactivity or exposure to microgravity impairs cardiovascular regulation and circulatory homeostasis. Cardiovascular changes associated with CVD, including resting tachycardia, decreased exercise capacity and autonomic impairments are reproduced in an animal ...
