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.

Objective Investigating dual-task (DT) performance during simulated weightlessness by water submersion, using a manual tracking and a choice reaction task. In contrast to previous work, we focus on performance changes over time.

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.

Decision making after 50 days of simulated weightlessness
Brain Research, 2009By restricting physical activity levels, the bed rest simulation of weightlessness could be associated with changes in prefrontal cortex functioning that manifest as cognitive decrements, particularly for executive cognitive functions. We aimed to determine if performance on an executive function task was indeed affected by bed rest.

The Effects of Simulated Weightlessness on Bone Maturation*
Endocrinology, 1987In earlier studies we showed that elevating the hind limbs of growing rats for up to 2 weeks results in a temporary cessation of bone growth in the hind limbs and a transient fall in the serum levels of 1,25-dihydroxyvitamin D. To determine whether such skeletal unloading also retards the maturation of bone, as seen in vitamin D-deprived animals, we ...
