Controlled studies using classic altitude
training showed an increase in SL performance and VO at altitudes
between 1,800 and 2,700 m (32,72).
Although previous studies reported that high altitude
predict CV events, did not evaluate the prognostic significance (2).
At some point, many pilots answer to ATC for blowing through an altitude
sickness - also known as Acute Mountain Sickness (AMS) -- is a pathological condition caused by acute exposure to low partial pressure of oxygen at high altitude
Several teams decided to live at low altitudes
(>500 m); whereas, others stayed at sea level during the World Cup.
The ice events also are nearly at sea level, with other venues ranging from altitudes
of around 2,600 feet for the sled events to around 5,000 feet for women's and men's downhill skiing.
Diffusing capacity predicted values, as well as results, are slightly different between sea level and at altitudes
of a little over 5,000 such as the case in Denver and Salt Lake City.
Although the system dramatically improves our ability to accurately measure altitudes
, its guaranteed accuracy is +-200 feet.
It's a paradox that there are different effects [of global warming] at high and low altitudes
, but both are real," Solomon says.
Perhaps others found the 4000 top altitude
confusing, given the 11,000 restriction at TERPZ.
Up to 15 % of travelers to altitudes
over 2,500 m (8,202 ft) will develop HAPE, depending on the traveler's age and sex, and the rate of ascent18.
The theory is that a phenomena termed ice crystal icing is occurring on warmer than freezing surfaces inside the engines operating at high altitudes
due to the ingestion of ice crystals .
