BACKGROUND AND PURPOSE At high altitudes barometric pressure is reduced and, thus, less oxygen is inhaled. Reduced oxygen concentration in brain tissue can lead to cerebral damage and neurological and cognitive deficits. The present study was designed to explore the effects of high-altitude exposure using a quantitative MRI technique, voxel-based morphometry. METHODS We studied nine world-cla...

introduction: sensory-motor control and in general gaining balance will be impaired after an ankle injury and in fatigue situations. the aim of this research was to study the effect of exercise-based fatigue on static and dynamic balance in mountaineering athletes who were successful in returning to a suitable level of physical activity after an ankle sprain injury. materials and methods: 25 ac...

The main purpose of this study is to analyze climbers involved in motivation and risk perception and analysis of the predictive ability of the risk perception "mountaineering" involved in motivation. This study used questionnaires, to have to climb the 3000m high mountain in Taiwan climbers object to carry out an investigation in order to non-random sampling, a total of 231 valid questionnaires...

Using people actively involved in mountain climbing, this thesis explores people‟s motivations to participate in mountain climbing, an activity frequently characterised in terms of risk. Moreover, using a variety of both quantitative and qualitative methods the assessment of the role of risk as a motivation for mountain climbing is central to the thesis. The first study (N = 232) employed a the...

Functional accounts of hierarchy propose that hierarchy increases group coordination and reduces conflict. In contrast, dysfunctional accounts claim that hierarchy impairs performance by preventing low-ranking team members from voicing their potentially valuable perspectives and insights. The current research presents evidence for both the functional and dysfunctional accounts of hierarchy with...

Increasing numbers of climbers are attempting Mount Everest, the highest mountain on Earth. We compiled interview data and computed the probabilities of summiting and of dying as a function of climber age and gender (2211 climbers, spring season) for the period of 1990-2005. Men and women had similar odds of summiting and of dying. However, climbers older than 40 years have reduced odds of summ...

Abstract Background & Aims: In regard to the limited studies about the effect of creatine on exercise-induced inflammatory responses, the present study was conducted to identify the effect of creatine monohydrate loading on response of serum C-reactive protein (CRP), interleukin-6 (IL-6) and peripheral blood leucocytes following one bout downhill running in male mountain climbers. Methods: Twen...

The increased prevalence of high altitude sickness such as Acute Mountain Sickness (AMS), High Altitude Cerebral Edema (HACE), and High Altitude Pulmonary Edema (HAPE) are related to the increasing popularity of mountain climbing as an adventure sport; and the increasing ease, and decreasing cost of travel to popular climbing tourist destinations. This precludes the usual preparations and adapt...
