Is Autonomic Modulation Different between European and Chinese Astronauts?
PURPOSE The objective was to investigate autonomic control in groups of European and Chinese astronauts and to identify similarities and differences. METHODS Beat-to-beat heart rate and finger blood pressure, brachial blood pressure, and respiratory frequency were measured from 10 astronauts (five European taking part in three different space missions and five Chinese astronauts taking part i...
متن کاملOperational Radiation Protection for European Astronauts
Since the early times of human spaceflight radiation has been, besides the influence of microgravity on the human body, recognized as a main health concern to the astroand cosmonauts. The radiation environment that the crew experiences during a space flight differs significantly to that found on earth due to particles of greater potential for biological damage. High-energetic charged particles,...
متن کاملAdaptation of autonomic heart rate regulation in astronauts after spaceflight
BACKGROUND Spaceflight causes changes in the cardiovascular control system. The aim of this study was to evaluate postflight recovery of linear and nonlinear neural markers of heart rate modulation, with a special focus on day-night variations. MATERIAL/METHODS Twenty-four-hour Holter ECG recordings were obtained in 8 astronauts participating in space missions aboard the International Space S...
متن کاملEffects of Autonomic Modulation
The development left ventricular hypertrophy (LVH) represents a critical milestone in patients with hypertensive heart disease (HHD). This structural remodeling and the associated abnormalities in diastolic function portend an increased risk of both mortal and morbid events (1–4). Treatment that results in the regression of LVH is associated with a reduction in these event rates (5–8). However,...
