Effect of acclimatisation to altitude on learning.
Long-term exposure to high altitude has been reported to impair cognitive functions, possibly resulting in an increased risk of mountain accidents. To assess the modification of cognitive functions during acclimatisation to altitude, 17 climbers were studied at 5350 m a.s.l. by means of a neuropsychological learning test. The results clearly show that by extending the period spent at elevations...
متن کاملAdaptation and acclimatisation in humans and animals at high altitude.
Rapid ascent into high altitude or permanent residence there leads to a wide range of disturbances of function or alterations in histological appearances in most organs of the body. The influences which lead to these changes are those inherent in the environment of high altitude, especially hypobaric hypoxia resulting from the diminished barometric pressure. One of the major aspects of research...

R ECENT ADVANCES in aircraft design have made possible attainment of altitudes in which man is unable to live, even while breathing pure oxygen. This difficulty has been overcome by the development of pressurized cabins and, to some extent, by the use of pressure-breathing equipment. The latter effectively increases alveolar oxygen tension; however, there has been some uncertainty as to whether...
متن کاملSmoking, acute mountain sickness and altitude acclimatisation: a cohort study.
RATIONALE The relationship between cigarette smoking and acute mountain sickness (AMS) is not clear. OBJECTIVE To assess AMS risk and altitude acclimatisation in relation to smoking. METHODS 200 healthy non-smokers and 182 cigarette smokers were recruited from Han lowland workers.

متن کاملWellness, fatigue and physical performance acclimatisation to a 2-week soccer camp at 3600 m (ISA3600)
OBJECTIVES To examine the time course of wellness, fatigue and performance during an altitude training camp (La Paz, 3600 m) in two groups of either sea-level (Australian) or altitude (Bolivian) native young soccer players. METHODS Wellness and fatigue were assessed using questionnaires and resting heart rate (HR) and HR variability. Physical performance was assessed using HR responses to a s...
