Regional changes in cerebral blood flow between the upright and supine posture and over 3 days of bed rest

Experimental Physiology, EarlyView.
Abstract A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 ...

Effects of 60 days of 6° head-down bed rest on the composition and function of the human gut microbiota

iScience, 2023
Summary: Spaceflight is rigorous and dangerous environment which can negatively affect astronauts’ health and the entire mission. The 60 days of 6° head-down bed rest (HDBR) experiment provided us with an opportunity to trace the change of gut microbiota

Jumping on the moon as a potential exercise countermeasure

Experimental Physiology, EarlyView.
Abstract The Moon's gravitational field strength (17% Earth's gravity) may facilitate the use of bodyweight jumping as an exercise countermeasure against musculoskeletal and cardiovascular deconditioning in reduced gravity settings. The present study characterised the acute physiological and kinetic responses to bodyweight jumping in simulated Lunar ...

ATHLETIC: An exoskeleton countermeasure exercise device for resistive and plyometric training in deep‐space missions

Experimental Physiology, EarlyView.
Abstract Prolonged exposure to weightlessness leads to loss of muscle and bone mass. Therefore, astronauts on board the International Space Station (ISS) currently perform mandatory daily exercises. ISS missions usually last 6 months, and future missions will become significantly longer when going, for example, to Mars.
