Funkcionise ako se precizno odredi interval u kom ce biti smanjen dotok kiseonika i na koju kolicinu...
princip sa tom maskom je slican vezbanju/pripremama na vecoj nadmorskoj visini... na planinama je vazduh "redji" tj. vazdusni pritisak je manji pa manje molekula kiseonika moze da stane u kolicinu/zapreminu sta vec koju udises... slicna restrikcija se pravi i sa maskom....
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

to 4364 ml.min

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

.
As far as blood is concerned, we found an increase in the number of reticulocytes from
5.1000

to 7.1000

, which amounts to 40%.
