Hypoxia Clinical Trial
— HypoxiaOfficial title:
Aspects of Neuropsychological Assessment, Standard and Sleep Efficiency in People Exposed to Altitude
Aim: To evaluate the influence of oxygen deficit on the cognitive performance and also about
the architecture and sleep efficiency in volunteers subjected to mild and moderate exercise
in a hypobaric chamber. SUMMARY: Participants in this study 30 healthy male volunteers, aged
20 to 40 years, regular physical activity, constituting three groups: 1 - without
exercise-hypoxia group 10 volunteers who not be subjected to any kind of physical exercise
in hypoxia and remain all day of experiment, 2 - group exercise at sea level, is composed of
10 volunteers who will undergo a protocol exercise physical sea-level, 3 - group exercise
and hypoxia - 10 volunteers who will carry out a protocol exercise on a treadmill, being the
same in condition of hypoxia (hypobaric chamber). All groups on the first day of the
experiment will undergo baseline assessments, laboratory blood analysis salivary and
spirometric testing. Assessments will be personality and neuropsychological. After baseline
assessments, the last day of the experiment, the groups will be evaluated again 4350m above
sea level the sea, by personality tests, neuropsychological and laboratory. RATIONALE AND
BACKGROUND: During exposure to environments with a partial reduction of oxygen, human body
can undergo several physiological and psychological changes are not prepared for such
condition. Few studies have reported that the elevation changes and cognitive aspects
related to sleep.
MATERIAL AND METHOD: They describe the procedures to be performed, and the study conducted
in local with adequate infrastructure.
