BACKGROUND: Hypoxic tolerance varies from person to person. The aim of the present study was to verify clinical hypoxic test on athletes’ population across different sport specialization, training level and healthy individuals and show validity of this test on athletes’ population. METHODS: The study enrolled 310 healthy individuals from 20 to 69 years of age. Subjects underwent test for acute hypoxia breathing normobaric hypoxic air (6400 m, FIO2 10.1±0.1[%]) till oxygen saturation (SpO2), drops down to 80[%]. After arterial oxygen saturation rich 80[%] or doesn’t rich 80[%] during 300 sec subject switch to the breathing with atmospheric air till SpO2 rich 96[%]. For the calculation of hypoxic index (I-Hyp) time of reaching 80[%] is divided by time of restitution to the 96[%] of SpO2. Test was carried out in sitting position. Oxygen saturation in blood, heart rate and minute ventilation were recorded before, during and after the test. RESULTS: Highest hypoxic tolerance has been shown in breath-hold
