Exercise response to simulated weightlessness

Acta Astronautica, 1979
Two bed rest analog studies of space flight were performed; one 14 d and the other 28 d in duration. Exercise response was studied in detail during the 28 d study and following both the 14 d and 28 d studies. This paper relates the results of these studies to physiologic changes noted during and following space flight.

Simulated Weightlessness Induces Hippocampal Insulin Resistance and Cognitive Impairment

Life Sciences, 2023
Growing evidence highlights the potential consequences of long-term spaceflight, including gray matter volume reduction and cognitive dysfunction with subclinical manifestations of diabetes mellitus among astronauts, but the underlying mechanisms remain unknown. In this study, we found that long-term simulated weightlessness induced hippocampal insulin

Correlation of macro and micro cardiovascular function during weightlessness and simulated weightlessness

Acta Astronautica, 1988
The investigation of cardiovascular function necessarily involves a consideration of the exchange of substances at the capillary. If cardiovascular function is compromised or in any way altered during exposure to zero gravity in space, then it stands to reason that microvascular function is also modified.

An upper arm model for simulated weightlessness

Acta Physiologica Scandinavica, 2000
This investigation examined the effects of 4 weeks of non‐dominant arm unloading on the functional and structural characteristics of the triceps brachii muscle of six normo‐active college‐age males (age: 23 ± 1 years, height: 176 ± 4 cm, weight: 76 ± 6 kg).
