- Abstract
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%.
