High-Intensity Interval Training: A Potential Exercise Countermeasure During Human Spaceflight [PDF]

Frontiers in Physiology, 2019
High-intensity interval training (HIT) is an effective approach for improving a range of physiological markers associated with physical fitness. A considerable body of work has demonstrated substantial improvements in cardiorespiratory fitness following ...

Effects of Spaceflight on Human Skin [PDF]

Skin Pharmacology and Physiology, 2021
During both short- and long-duration spaceflight, several health problems can occur, including those of the skin. Astronauts in space and after returning to earth experience erythematous, burning, itchy, dry, sensitive, and thinning skin. Other skin problems, such as infections, abrasions, lacerations, delayed wound healing, and accelerated skin aging,

Uncertainty Quantification of Thermophysical Property Measurement in Space and on Earth: A Study of Liquid Platinum Using Electrostatic Levitation

Journal of Astronomy and Space Sciences, 2023
A study of uncertainty analysis was conducted on four key thermophysical properties of molten Platinum using a noncontacting levitation technique. More specifically, this work demonstrates a detailed reporting of the uncertainties associated with the ...

The Cardiovascular System in Space: Focus on In Vivo and In Vitro Studies

Biomedicines, 2021
On Earth, humans are subjected to a gravitational force that has been an important determinant in human evolution and function. During spaceflight, astronauts are subjected to several hazards including a prolonged state of microgravity that induces a ...

Impact of diet on human nutrition, immune response, gut microbiome, and cognition in an isolated and confined mission environment

Scientific Reports, 2022
Long-duration spaceflight impacts human physiology, including well documented immune system dysregulation. The space food system has the potential to serve as a countermeasure to maladaptive physiological changes during spaceflight.

Effects of a Closed Space Environment on Gene Expression in Hair Follicles of Astronauts in the International Space Station. [PDF]

PLoS ONE, 2016
Adaptation to the space environment can sometimes pose physiological problems to International Space Station (ISS) astronauts after their return to earth. Therefore, it is important to develop healthcare technologies for astronauts.

Adjuvant pharmacological strategies for the musculoskeletal system during long‐term space missions

British Journal of Clinical Pharmacology, EarlyView., 2023
Abstract Despite 2 h of daily exercise training, muscle wasting and bone loss are still present after 6‐month missions to the international space station. Some crew members lose bone much faster than others. In preparation for missions to the Moon and Mars, space agencies are therefore reviewing their countermeasure portfolios.
