Cardiopulmonary Resuscitation in Hypogravity Simulation.

Aerospace Medicine and Human Performance, 2021
BACKGROUND: Limited research exists into extraterrestrial CPR, despite the drive for interplanetary travel. This study investigated whether the terrestrial CPR method can provide quality external chest compressions (ECCs) in line with the 2015 UK resuscitation guidelines during ground-based hypogravity simulation.

Synaptic Aspects of Hypogravity Motor Syndrome

Biophysics, 2019
© 2019, Pleiades Publishing, Inc. Abstract—This paper provides a review of studies on the effects of hypogravity on neuromuscular system function. It is known that exposure to microgravity causes a series of events that occur in the neuromuscular system, leading to the development of so-called “hypogravity motor syndrome.” Despite a large number of ...

Water Immersion as a Model of Hypogravity

Bulletin of Experimental Biology and Medicine, 2019
We studied the effects of hypogravity modeled by water immersion on cognitive functions and physiological parameters of monkeys. Cognitive capacities of monkeys were evaluated using computer-controlled joystick task with food reward in case of target hit.

A Method of Ground Simulation of Physiological Effects of Hypogravity on Humans

Bulletin of Experimental Biology and Medicine, 2016
A novel method of ground simulation in humans of physiological effects induced by the stay on the surface of celestial bodies with hypogravity was developed and successfully tested. This method is based on the change of gravity force angle, which decreases the gravitational component of the blood hydrostatic pressure characteristic of human vertical ...

The role of calcium ions in cytological effects of hypogravity

Advances in Space Research, 1984
Electron-cytochemical and biochemical methods made it possible to reveal certain differences in ATPase activity stimulation by calcium ions in root apex cells of pea seedlings and moss protonema Funaria hygrometrica grown under stationary and slow clinostatic (2 rev/min) conditions. It was showed that under clinostatic conditions in comparison with the

Sensorimotor function may be fundamentally limited in hypogravity

Journal of Applied Physiology
Prior studies suggest that humans can adapt to hypogravity (i.e., 0–1.0 Earth G). We examined human manual control performance during the transition from an Earth-gravity to a hypogravity condition. We found that performance worsened significantly after the transition.

Metabolism and biochemistry in hypogravity

Acta Astronautica, 1991
The headward shift of body fluid and increase in stress-related hormones that occur in hypogravity bring about a number of changes in metabolism and biochemistry of the human body. Such alterations may have important effects on health during flight and during a recovery period after return to Earth.

Epinastic Thresholds in a Simulated Hypogravity Environment

Physiologia Plantarum, 1971
AbstractThe morphological changes of several grasses, dicotyledons and thallial plants to decreasing increments of gravity from the normal 1 g to 0 g were determined. The various levels of simulated hypogravity were obtained by regulation of the angles of the rotating clinostats.

Development of Walking Pattern Evaluation System for Hypogravity Simulation

2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006
There are three primary techniques for simulating partial gravity: water immersion (neutral buoyancy), parabolic flight, and body suspension device (BSD) models. Underwater Immersion. During tests, a neutrally buoyant subject is ballasted to simulate the desired partial gravity loading.
