In this thesis the survey was conducted in order to evaluate the ability of maximal oxygen consumption among women aged 20 to 29 years and to identify possible differences in the level of this ability in smokers and non-smokers , as well as to determine the possible correlation between the smoking period and intensity and relative maximum oxygen consumption. The sample included 65 females aged 20 to 29 years (33 smokers and 32 non-smokers) , which in recent months haven’t practiced some form of regular aerobic activity. This sample was taken in an indirect test for the assessment of maximal oxygen consumption UKK 2km walking test. Based on the results of T-test statistically signifi cant difference (t = 0.01), for the level of signifi cance p <0.05 , was shown between the relative values of maximal oxygen uptake women smokers and non-smokers , in favor of non-smokers . A statistically signifi cant difference (t = 0.02) , for the level of signifi cance of p < 0.05, was found between the relative values of maximal oxygen consumption expressed in relation to lean body mass component in women smokers and non-smokers , in favor of non-smokers. Also , using the T -test , it was found that there was no signifi cant difference in basic anthropometric indicators of women smokers and nonsmokers. By using Pearson’s correlation coeffi cient it was found that between smoking duration and intensity of smoking and maximal oxygen consumption of women smokers exists a low negative correlation (-0.49). Results of this study confi rmed the results of previous researches on the signifi cance of the difference between the ability of maximal oxygen consumption among smokers and non-smokers. However , unlike previous studies , correlation between maximal oxygen consumption and smoking duration and intensity of smoking has not been proven.
