Structural damage to the rat eye following long-term simulated weightlessness.
Experimental Eye Research, 2022To better perform space missions and develop human spaceflights, the eye health of astronauts is receiving increasing attention from researchers. In this study, we used prolonged tail suspension to simulate microgravity cephalad fluid shift in space to ...

Exercise response to simulated weightlessness
Acta Astronautica, 1979Two 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.

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, 2000This 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).

Effects of muscle electrostimulation during simulated weightlessness
Acta Astronautica, 1975In a 45-day experiment test subjects were exposed to bed rest with their heads down at -4 degrees C. Twice a day their muscles of the stomach, back, femur, and shin were stimulated with electric current for 25-30 min. The value of muscle tension was close to their maximum voluntary contraction.

Long-term spaceflight can lead to changes in eye structure and decreased visual function. At present, there are almost no effective methods to prevent and treat eye damage caused by microgravity environments.
