altitude

He assigned a height of 11,400 feet to the maximum elevations, and reduced the mean of the different altitudes to little more than 2,400 feet.

Unconsciousness comes quickly at this altitude," she said quietly.

Leaping for the altitude control Gahan pulled it wide.

Some are known to you, such as the thermometer, which gives the internal temperature of the Nautilus; the barometer, which indicates the weight of the air and foretells the changes of the weather; the hygrometer, which marks the dryness of the atmosphere; the storm-glass, the contents of which, by decomposing, announce the approach of tempests; the compass, which guides my course; the sextant, which shows the latitude by the altitude of the sun; chronometers, by which I calculate the longitude; and glasses for day and night, which I use to examine the points of the horizon, when the Nautilus rises to the surface of the waves.

Two studies using IHT for 90-120 minutes in 10 consecutive days and altitudes between 2, 5 00 and 4,400 m, reported a significant improvement in the anaerobic parameters of the hypoxic training groups compared with control groups (67,68).

Many of the previous studies have shown that altitude generates a thrombogenic environment, and so cardiovascular event (CV) events are more common at high altitudes (1).

One benefit of flying with a PFD is the ability to bug altitudes using the altitude tape display and alert function.

Some of the contributing factors to the onset and severity of high-altitude illness are dehydration due to the higher rate of water vapour lost from the lungs at higher altitudes, the rate of ascent, altitude attained, amount of physical activity at high altitude, as well as individual susceptibility.

Whereas the optimal organization of altitude training to optimize performance at sea level is heavily discussed in the scientific community, the benefit of altitude acclimatization (about 1 to 2 weeks) for competitions at moderate altitudes above 2,000 m is well established (2).

At higher altitudes, the body initially delivers less oxygen to muscles, which can result in fatigue occurring sooner during exercise.

Pulmonary function studies are also performed at higher altitudes such as 15,000 feet as in the case of some cities in Peru and in the Himalayas.
