Greater brain volumes are activated when performing simple calculating tasks in persons accustomed to lower altitudes than those to higher altitudes
Chronic exposure to a hypoxic environment results in a number of physiological changes such as cardiac arrhythmia and pulmonary edema. We hereby studied the variations in activation of brain areas during simple calculation tasks between individuals originating from different altitudes. Two groups of subjects, one from 1700 m above sea level (lowlanders) and the other one from at least 3000 m ab...
متن کاملRates of Concussion Are Lower in National Football League Games Played at Higher Altitudes
W hile concussions occur in nearly every sport and level of competition, the greatest frequency occurs in collision and contact sports such as football, lacrosse, hockey, rugby, soccer, and basketball.16,22,27 Specifically with regard to football, attempts at player-safety improvements for concussion prevention date back to the implementation of helmets by the National Football League (NFL) in ...
متن کاملRates of concussion are lower in National Football League games played at higher altitudes.
STUDY DESIGN Retrospective epidemiologic investigation. OBJECTIVE To investigate the relationship between altitude and concussion rate in the National Football League (NFL). Because of the physiologic responses that occur during acclimatization to altitude, it was hypothesized that games played on fields at a higher altitude would have reduced concussion rates compared to games played on fiel...
متن کاملHuman responses to extreme altitudes.
It is a strange coincidence that the highest point on Earth is very close to the limit of human tolerance to hypoxia. The physiological changes that allow humans to reach these extreme altitudes involve enormous alterations of their normal state. It is useful to contrast this response with two others to high altitude. One is acclimatization that allows lowlanders to ascend to altitudes of up to...
متن کاملCarotid body tumors in inhabitants of altitudes higher than 2000 meters above sea level.
BACKGROUND Carotid body tumors (CBTs) are rare. Diagnosis is usually delayed until the tumors reach a critical volume and a mass appears in the neck, which is often asymptomatic. METHODS We reviewed retrospectively the cases with CBT diagnosed from 1965 to 1995 in the Hospital de Oncologia in Mexico City with inhabitants at an altitude higher than 2200 m above sea level to see whether these t...
