摘要：Our interest in this research was directed towards finding the answer to the question if the results for the evaluation of maximal aerobic power would be significantly different if they were measured by two different ergometers, and two different procedures which are used in the testing. The sample consisted of 64 young basketball players, 15-17 years old. The evaluation of the maximal oxygen consumption rate was determined by the Astrand evaluation test on bicycle ergometer and by the Von Doblen step test with a gym bench height of 30, 40, 50.8cm. Spearman’s rank correlation coefficient and the Student’s T-test were used as statistical procedures. The results indicate that the values of the maximal oxygen consumption rate of the participants measured by the Astrand test on a bicycle ergometer and the step test evaluated by the Von Doblen formulae are significantly different. 77% of the participants had a higher oxygen consumption rate on the step test. The differences can be explained by the fact that the physiological reaction of the body is different in comparison to work on a bicycle ergometer. The work on a gym bench in relation to a bicycle ergometer is different based on the engaged muscles and their mass, and because of that the load of the cardio vascular system is different. It means that the organism does not have the same physiological reaction to different types of load even when it is the same in terms of the size of the work.
