Abstract		The aim of the study was to establish the differences in air consumption per minute and air consumption per minute per kg of body mass between male and female beginning divers. Forty beginning divers (20 male and 20 female participated in the study, all students at the University of Ljubljana enrolled in obligatory physical activity program. Two sets of measurements were performed: the measurement of air consumption during low intensity swimming at a depth of 2,8 m, and the measurement of air consumption during the rest at a depth of 3.4 m. The variables used for statistical analysis were air consumption per minute and air consumption per minute per kg of body mass, both during swimming and at rest. SPSS program was used for basic statistical analysis, T test and analysis of covariance were used to assess the difference between selected variables. The results of the study have shown that with male beginners the air consumption is substentially higher and less economical than with female beginning divers.
Summary		V raziskovalni nalogi smo ugotavljali razlike med spoloma v minutni porabi zraka pri potapljačih začetnikih in razlike v porabi zraka na kilogram telesne teže. Naš vzorec merjencev (40 potapljačev začetnikov, od tega 20 merjencev ženskega in 20 moškega spola) je predstavljal populacijo študentov ljubljanske univerze z obvezno športno vzgojo. Z vzorcem populacije smo opravili dve merjenji. Pri prvem smo ugotavljali porabo zraka pri plavanju nizke intenzivnosti na globini 2,8 metra, pri drugem pa porabo zraka v mirovanju na globini 3,4 metra. Spremenljivke, ki smo jih upoštevali pri statistični obdelavi podatkov, so minutna poraba zraka ter minutna poraba zraka na kilogram telesne teže pri plavanju in v mirovanju. Osnovno statistiko smo izračunali v okviru programa SPSS. Za ugotavljanje razlik med izbranimi spremenljivkami smo uporabili T test in analizo kovariance. Na podlagi rezultatov naše raziskave lahko z zanesljivostjo trdimo, da potapljači začetniki porabijo bistveno več zraka kot začetnice in ga tudi manj gospodarno izkoriščajo.
