contribution. We know that high altitude leads to some negative effects without acclimatizing on pulmonary and cardiovascular systems. AMS is a syndrome due to the rapid ascending to high-altitude in aviators and mountaineers. It is a serious health problem especially in obese subjects. In present study, we want to learn that the subjects were taken to high altitude as volunteers or part of the...
INTRODUCTION Following the dominance of altitude acclimatised athletes during the 1968 Olympic Games held in Mexico City (2400 m), and early anecdotal training experiments in the USA in the 1970s, altitude (hypoxic) training has become very popular among individual endurance athletes including marathon runners, cyclists, swimmers and triathletes. Altitude training is used to further enhance exe...
Previous studies suggest that genetic factors and acclimation can account for differences in aerobic performance (V(O(2)max)) between high and low altitude populations of small mammals. However, it remains unclear to what extent development at different oxygen partial pressures (P(O(2))) can affect aerobic performance during adulthood. Here we compared the effects of development at contrasting ...
BACKGROUND Altitude training is used by elite athletes to improve sports performance, but it may also disrupt sleep. The aim of this study was to examine the effects of 2 weeks at high altitude on the sleep of young elite athletes. METHODS Participants (n=10) were members of the Australian under-17 soccer team on an 18-day (19-night) training camp in Bolivia, with six nights at near sea level...
CONTEXT Athletes at different skill levels perform strenuous physical activity at high altitude for a variety of reasons. Multiple team and endurance events are held at high altitude and may place athletes at increased risk for developing acute high altitude illness (AHAI). Training at high altitude has been a routine part of preparation for some of the high level athletes for a long time. Ther...
While the skin microbiome has been shown to play important roles in health and disease in several species, the effects of altitude on the skin microbiome and how high-altitude skin microbiomes may be associated with health and disease states remains largely unknown. Using 16S rRNA marker gene sequencing, we characterized the skin microbiomes of people from two racial groups (the Tibetans and th...
In studies concerned with the performance at high altitude it is often not possible to separate the effects which are due to hypoxia from those associated with the stress of ascent. Some of the basic observations concerning exercise at high altitude are reviewed and a study is described which was designed to simulate the physical exertion of high altitude mountaineering but performed at altitu...
OBJECTIVE To investigate the altitude, immigration and suicide rates association in Turkey. METHODS Suicide and immigration rates of 81 provinces and their elevation data were obtained. RESULTS There were not significant correlations between country elevation, immigration and mean suicide rate. CONCLUSION The findings of this study points out that altitude related hypoxia and suicide asso...
rashe grape cultivar grows in kurdistan province in rain fed conditions. microclimate conditions have a great effect on grape berry quality. information about changes in grape berry composition in the relation to climate changes is limited. in order to measure the effects of slope and altitude on some grape berry chemical composition, a study was conducted on grape cv. ‘rasheh’ in university of...
The focus of the present study was to investigate the chemical composition of essential oil of Salvia hydrangea DC. ex Benth. growing wild in Kiasar-Hezarjrib, Iran. In addition, effects of altitude and some soil properties on the essential oil quality and quantity of S. hydrangea was identified. The samples collected from two altitudes (1100 and 2000 m) in blossoming period, were analyzed by h...
