The Influence of Low Altitude Training on Collegiate Distance Runners

摘要

To investigate the influence of exposure to low altitude on flat sea level running performance, we measured the changes of red cell indices in middle and-long distance student runners before and during a summer training camp at 1,000 m above sea level. 2,3-diphosphoglycerate (2,3-DPG) concentrations in blood increased significantly from 2.31 ± 0.36 μmol/ml before, to 2.69±0.56 μmol/ml during the camp (P<0.05). Hematocrit (Hct) before the camp was 43.0 ± 4.2%, and was significantly (F<0.01) decreased during the camp (40.2 ± 3.7%). Hemoglobin (Hb) concentration was not changed before and during the camp. The present study demonstrated that a low altitude of 1,000 m was not sufficient to increase Hct or Hb, but did appear to increase 2,3-DPG concentrations.
