The purpose of the master's thesis was to determine the differences in energy expenditure in sports activities of pre-school children by means of the energy expenditure meter, depending on the different learning forms (polygon, training by stations). We were also interested in the reasons why there are deviations in energy expenditure and the difference in energy expenditure by gender. To get data we helped with using the BodyMedia SenseWear energy meters. The sample included 12 children aged 4–6 who attend the kindergarten in Ljubljana. We performed the measurments twice. The data were processed using the SPSS statistical program. To verify the hypothesis, a t-test for dependent samples was used. The research showed that there are no significant differences in any of the energy expenditure indicators between different learning forms. The tendency for the existence of characteristic differences was recorded only in the number of steps (t = 2,060, p = 0,064). Here we found out that there were made 184 steps more on the polygon than in the course of training by stations. In contrast, we found 24 kJ and 0,52 MET higher energy expenditure in the course of training by stations. Nevertheless, these differences were too small to achieve statistical significance. We also found that there are no significant differences between boys and girls in energy expenditure, number of steps and the metabolic equivalent, but in the case of metabolic equivalence (t = 2,027; p = 0,070), training by stations shows a moderate tendency for the existence of distinctive gender differences in favor of boys. We also found that both learning forms achieve or even exceed the recommendation on the intensity of exercise.
