Human Factors in High-Altitude Mountaineering
We describe the human performance and cognitive challenges of high altitude mountaineering. The physical (environmental) and internal (health) stresses are first described, followed by the motivational factors that lead people to climb. The statistics of mountaineering accidents in the Himalayas and Alaska are then described. We then present a detailed discussion of the role of decision-making ...
متن کاملEffect of menstrual cycle phase on exercise performance of high-altitude native women at 3600 m.
At sea level normally menstruating women show increased ventilation (VE) and hemodynamic changes due to increased progesterone (P) and estrogen (E2) levels during the mid-luteal (L) compared to the mid-follicular (F) phase of the ovarian cycle. Such changes may affect maximal exercise performance. This repeated-measures, randomized study, conducted at 3600 m, tests the hypothesis that a P-media...
متن کاملDiabetes and extreme altitude mountaineering.
Increasing numbers of people with diabetes are seeking advice about participation in high altitude climbing, which has the problems of serious metabolic demands, a high likelihood of acute mountain sickness (AMS), and leaving the climber remote from medical care. The American Diabetes Association states that “all levels of exercise, including leisure activities, recreational sports, and competi...
متن کاملHydration Status as a Predictor of High-altitude Mountaineering Performance
BACKGROUND Hydration status is a controversial determinant of athletic performance. This relationship has not been examined with mountaineering performance. METHODS This was a prospective observational study of mountaineers who attempted to climb Denali in Alaska. Participants' urine specific gravity (SG), and ultrasound measurements of the inferior vena cava size and collapsibility index (IV...
متن کاملThe Effect of Ten Days of Heat Acclimation on Exercise Capacity during Acute Altitude Exposure (4350 m)
Acclimation to one environmental stressor may enhance adaptations to various other stressors in humans; this phenomenon has been described as cross-tolerance. Approaches to induce altitude acclimation in a relatively short time frame are needed, thus the purpose of our study was to examine the effect of heat acclimation on exercise capacity during acute altitude exposure (4350 m). Eight trained...
