Effect of high terrestrial altitude and supplemental oxygen on human performance and mood.

Aviation, space, and environmental medicine, 1992
Sustained exposure to high terrestrial altitudes is associated with cognitive decrement, mood changes, and acute mountain sickness (AMS). Such impairment in aviators could be a safety hazard. Thirteen male soldiers, ages 19-24, ascended in 10 min from sea level to 4,300 m (simulated), and remained there 2.5 d.

Effects of different humidity levels on the human body in a high-temperature environment at high altitude

AHFE International
Workers in high-temperature, high-humidity, and low-oxygen environments face multiple environmental stressors, leading to increased blood circulation, changes in metabolic heat production, elevated heart rates, and reduced nerve sensitivity. These factors may contribute to a significant heat stress on the body, which directly reduces physical work ...

The effects of physical exercise at high altitude on adrenocortical function in humans.

Functional neurology, 1997
The combined effects of sustained physical activity and hypoxia on adrenocortical function were investigated in 14 healthy volunteers, 8 males and 6 females (mean age 40.9 +/- 3.3 years), during a scientific expedition in the Himalayas. Plasma cortisol levels were measured in all subjects in basal conditions and after the administration of 1 mg ...

Effect of time exposure to high altitude on zinc and copper concentrations in human plasma.

Aviation, space, and environmental medicine, 1999
Research has focused mainly on the relationship of zinc and copper contents and physical stresses like running, cycling, etc. It has also been reported that other forms of stresses change the concentration of these trace elements in humans. However,there are no reports on the effects of high altitude induced hypoxic stress on the plasma levels of these

[Effect of different schedules of motor activity on the processes of human adaptation to high-altitude conditions].

Kosmicheskaia biologiia i aviakosmicheskaia meditsina, 1976
Responses of external respiration, hemodynamics and blood were studied in 12 test subjects during their step-by-step adaptation to altitudes of 2200 and 3200 m. The test subjects were subdivided into two groups who were exposed to different schemes of motor activity--free motor activity and diminished motor activity during bed rest.

Effect of breathing of a helium-oxygen mixture on adaptation to effort in humans during high-altitude hypoxia.

Acta physiologica Polonica, 1987
The study was carried out on 17 healthy males aged 20-27 years subjected for 15 minutes to submaximal effort on a cycle ergometer (Elema-Schonander) under conditions of breathing ambient atmospheric air or a helium-oxygen mixture (20% O2 + 80% He) and under hypobaric pressure simulating an altitude of 3500 m above sea level.
