摘要：In our research we monitored the influence of intermittent hypoxic training on the body of an athlete. We evaluated oxygen saturation of the blood during hypoxia, which ranged from 90% down to 75%, at the end of a three-week course. These results were also confirmed by the oxygen content in the inhaled air, which at the end of the period dropped down even below 9%, and that corresponded to a simulated altitude of about 7000 m. Spiroergometry revealed an increase in VO2max, from 4105 ml.min-1 to 4364 ml.min-1, VO2max.kg-1 from 65,4 ml.min-1.kg-1 to 69,9 ml.min-1.kg-1 and submaximum performance W170 from 3, 34 W to 3, 40 W. Maximum performance in the 3-km walk improved by 13.7 seconds, the submaximum performance in the 10-km walk improved by 1:42 minutes. The load in the 10-km walk performed at the level of the anaerobic threshold showed an improvement of 1:29 minutes. We did not find any significant changes in the haematological components; the values of haemoglobin and haematocrit remained almost unchanged. A mild increase was recorded in the medium erythrocyte volume, which increased from 96.8 fl to 98.2 fl, and in the iron-binding capacity, which increased from 52 µmol.l-1 to 58 µmol.l-1. As far as blood is concerned, we found an increase in the number of reticulocytes from 5.1000-1 to 7.1000-1, which amounts to 40%
