High altitude acclimatization produces a suite of physiological changes that might support an improved athletic performance at low altitude and thus lead to the strategy of athletic training at high altitude. Although there is substantial literature on high altitude physiology in humans, there are few studies on horses. Our interest in the physiological responses to high altitude in equids has ...

BMJ | 22-29 DeceMBer 2007 | VoluMe 335 AbstrAct Objective To assess the effect of altitude on match results and physiological performance of a large and diverse population of professional athletes. Design Statistical analysis of international football (soccer) scores and results. Data resources FIFA extensive database of 1460 football matches in 10 countries spanning over 100 years. Results Alt...

Selenium (Se) levels in blood (whole blood, erythrocytes and serum) and blood glutathione peroxidase (GSH-Px) activity were investigated in people living at high altitude in Bolivia (4,000 m above sea level). These parameters were compared to those of people living at low altitude (300 m above sea level). The Se levels in whole blood of the high-altitude subjects did not differ significantly fr...

Abstract Purpose Main purposes of pre-acclimatization by hypoxia conditioning (HC) are the prevention high-altitude illnesses and maintenance aerobic exercise performance. However, robust evidence for those effects or evidence-based guidelines exposure strategies, including recommendations to ensure safety, largely lacking. Therefore, we summarize current knowledge on physiology acclimatization...

Extreme climatic conditions and hypobaric hypoxia at high altitude hinders the growth and productivity of chickens. The present study was carried out to examine the effect of aqueous extract of Prunus armeniaca seeds on health, survivability, antioxidants, plasma biochemical parameters, and immune status of broiler chickens at high altitude. Phytochemical analysis of extract revealed the presen...

BACKGROUND A paucity of knowledge currently exists surrounding the effects of altitude on femur fracture outcomes. The purpose of this study was to determine if altitude plays a significant role in determining the outcome of femoral shaft fractures in the elderly. The authors hypothesized that the additional cardiopulmonary stress of altitude would promote poorer outcomes of those individuals t...

Introduction: Moderate altitude training has become popular to improve competition performance in swimming both at altitude and sea level. The aim of the present study was to examine the influence of moderate altitude training on lactate curve during three weeks and after the exposure to altitude training at 1860 m and to examine the effects of altitude training on selected blood parameters bef...

Acute altitude illnesses are potentially serious conditions that can affect otherwise fit individuals who ascend too rapidly to altitude. They include high altitude headache, acute mountain sickness, high altitude cerebral oedema, and high altitude pulmonary oedema. The number of people travelling to altitude for work (soldiers, miners, construction workers, and astronomers) or for recreation (...

This paper provides the overview of an integrated, multi-disciplinary effort to study the effects of the 29 March 2006 total solar eclipse on the environment, with special focus on the atmosphere. The eclipse has been visible over the Eastern Mediterranean, and on this occasion several research and academic institutes organised co-ordinated experimental campaigns, at different distances from ec...

Sheep in Ethiopia are adapted to a wide range of environments, including extreme habitats. Elucidating their genetic diversity is critical for improving breeding strategies and mapping quantitative trait loci associated with productivity. To this end, the present study investigated the genetic diversity and population structure of five Ethiopian sheep populations exhibiting distinct phenotypes ...
