Why the study?
Does long-term exposure to microgravity affect autonomic cardiovascular control in cosmonauts?
Does long-term exposure to microgravity affect autonomic cardiovascular control in cosmonauts?
Long-duration spaceflight (9 months) reduces vagal-cardiac nerve traffic and decreases vagal baroreflex gain, with physiological changes persisting for at least 2 weeks after returning to Earth.
No takes yet. Share an insight, caveat, or question.
Microgravity may impair vagal baroreflex gain persisting post-flight; hypothesis-generating for long-duration spaceflight countermeasures.
Cooke et al. (2000) studied this question.
