The athlete at high altitude.
Track times at moderate altitudes (7000 to 8000 feet) are modified by decreased wind resistance and by systemic disturbances such as mountain sickness, disruption of training, and a decrease of maximum oxygen intake. The optimum period of acclimatization is probably two to three days. This permits adjustment of cerebrospinal fluid acid-base balance, but minimizes disturbances of plasma volume and stroke volume. Further study is needed to establish whether altitude training can improve performance in sea-level competitions.
