Gender Influence on the Performance of Chest Compressions in Simulated Hypogravity and Microgravity
Aviation, Space, and Environmental Medicine, 2012In the event of a cardiac arrest during microgravity exposure, external chest compressions (ECCs) which form the main part of basic life support should be carried out while the advanced life support equipment is being deployed. This study was aimed to determine if there was any gender difference in the effectiveness of performing ECCs using a body ...

Research on the adaptation of skeletal muscle to hypogravity: Past and future directions
Advances in Space Research, 1983Our current understanding of hypogravity-induced atrophy of skeletal muscles is based primarily on studies comparing pre- and post-flight properties of muscles. Interpretations are necessarily qualified by the assumption that the stress of reentry and readjustment to terrestrial gravity do not alter the parameters being analyzed.

Light microscopic analysis of the gravireceptor in Xenopus larvae developed in hypogravity
Advances in Space Research, 1989The paper describes an investigation of the influence of gravity on the early differentiation of gravity receptors in Xenopus embryos and larvae. There is evidence that the expression of crystals in the saccus endolymphaticus was statistically greater when the embryos developed in near weightlessness (hypogravity) than on earth. The function of these

Hypogravity increases cyclopiazonic acid sensitivity of rat soleus muscle
Journal of Applied Physiology, 1996The functional capacity of skeletal muscle sarcoplasmic reticulum was explored in slow rat soleus muscle after 21 days of hindlimb suspension. The sarcoplasmic reticulum function was assessed in intact and saponin-skinned fibers by using cyclopiazonic acid, a specific Ca(2+)-adenosinetriphosphatase inhibitor.

A methodology for hypogravity gait analysis with design application. [PDF]
, 2016 In order to support safety and performance through the design of future Moon and Mars habitats, the walking patterns and interactions of astronauts in the interior architecture need to be investigated. Data on anthropometrical and interaction movements need to be collected in order to address the design of the habitat.

Hypogravity‐induced atrophy of rat soleus and extensor digitorum longus muscles
Muscle & Nerve, 1987AbstractProlonged exposure of humans to hypogravity causes weakening of their skeletal muscles. This problem was studied in rats exposed to hypogravity for 7 days aboard Spacelab 3. Hindlimb muscles were harvested 12–16 hours postflight for histochemical, biochemical, and ultrastructural analyses.

Tropistic responses of Avena seedlings in simulated hypogravity.
Microgravity science and technology, 1997Results from investigation of the gravitropic responses of the Avena coleoptile under simulated weightlessness are presented. The tests were conducted using the flight hardware, identified by NASA as the Gravitational Plant Physiology Facility (GPPF), designed to support the Spacelab experiment, GTHRES.

[Myelination disorders in mechanism of hypogravity motor syndrome development].
Biofizika, 2012When modeling effects of hypogravitation by the method of hindlimb unloading in rats the area of cross-section in lumbar part of a spinal cord was found to reduce. The analysis of spinal cord slides showed that these changes are associated with a decrease in the area of white substance of a spinal cord.
