Loss of parafollicular cells during gravitational changes (microgravity, hypergravity) and the secret effect of pleiotrophin. [PDF]

PLoS ONE, 2012
It is generally known that bone loss is one of the most important complications for astronauts who are exposed to long-term microgravity in space. Changes in blood flow, systemic hormones, and locally produced factors were indicated as important elements

Acute effects of posture on intraocular pressure.

PLoS ONE, 2020
Many experiments have documented the response of intraocular pressure (IOP) to postural change. External forces caused by gravitational orientation change produce a dynamic response that is encountered every day during normal activities. Tilting the body

Performances in extreme environments: effects of hyper/hypobarism and hypogravity on skeletal muscle

European Journal of Translational Myology, 2010
Many environmental factors may affect muscle plasticity but some have exclusive characteristics that allow them to play a key role to maintain the muscle capacity to generate force; these factors are: i) the oxygen availability and ii) the load applied ...

Physiological Aspects of Walking in Simulated Hypogravity [PDF]

, 2015
The purpose of this study was to compare the differences in gait between land (1G), Lunar (Lunar G), and Martian (Mars G) based ambulation. Nine subjects (mean age = 24.2 ± 3.4; weight = 69.88 ± 14.65kg; height = 163.22 ± 7.8cm; 5 male and 4 female) were placed in a Body Suspension Device (BSD) and had baseline oxygen consumption (VO2) measured along ...
