Repeatability of artificial gravity tolerance times [PDF]

open access: yesFrontiers in Physiology
IntroductionExposure to microgravity results in physiological deconditioning, including orthostatic intolerance. Artificial gravity (AG) from short-arm centrifuges is being tested in ground-based studies to counter these effects.

Artificial Gravity

open access: yes, 2007
Protecting the health, safety, and performance of exploration-class mission crews against the physiological deconditioning resulting from long-term weightlessness during transit and long-term reduced gravity during surface operations will require effective, multi-system countermeasures.

Artificial gravity field

open access: yesResults in Physics, 2013
AbstractUsing computer algebra to run Einstein’s equations “backward”, from field to source rather than from source to field, we design an artificial gravity field for a space station or spaceship. Everywhere inside astronauts experience normal Earth gravity, while outside they float freely.

Theory of Artificial Anti-gravity

open access: yes, 2022
To overcome the shortage of traditional flight mechanism, we propose a type of anti-gravity engine based on General Relativity. Natural anti-gravity phenomenon is found under special spacetime background by analysis geodesic motion of spacecraft and vanishment of Riemann curvature locally, which demonstrates the feasibility of artificial anti-gravity ...

Acute cardiovascular and muscular response to rowing ergometer exercise in artificial gravity – a pilot trial [PDF]

open access: yesnpj Microgravity
Prolonged immobilization and spaceflight cause cardiovascular and musculoskeletal deconditioning. Combining artificial gravity through short-arm centrifugation with rowing exercise may serve as a countermeasure.

The application of artificial gravity in medicine and space. [PDF]

open access: yesFront Physiol, 2022
Gravity plays a crucial role in physiology. The lack of gravity, like in long duration spaceflight missions, cause pathologies in e.g., the musculoskeletal system, cardiovascular deconditioning, immune system deprivation or brain abnormalities, to just mention a few.

Artificial Gravity for Humans in Space: Philosophical and Methodological, Historical, Technological, and Futurological Aspects [PDF]

open access: yesФилософия и космология, 2021
The article presents the research materials and results on artificial gravity for humans in space. We analyse several important and interrelated aspects of the development and application of artificial gravity in manned spaceflights and providing ...

Comparison of trunk muscle exercises in supine position during short arm centrifugation with 1 g at centre of mass and upright in 1 g

open access: yesFrontiers in Physiology, 2022
Spaceflight is associated with reduced antigravitational muscle activity, which results in trunk muscle atrophy and may contribute to post-flight postural and spinal instability.

The Mobile Lower Body Negative Pressure Gravity Suit for Long-Duration Spaceflight

open access: yesFrontiers in Physiology, 2020
Spaceflight Associated Neuro-ocular Syndrome, bone decalcification, and muscle atrophy are among the most prevalent risks associated with long-duration spaceflight. Implementing the lower body negative pressure (LBNP) method is a potential countermeasure
