'Jirák Z, Šimíček J, Bužga M, Tomášková H, Křenková M, 2003: Trend of Fitness and Selected Anthropological Characteristics of the Young Population in the North Moravian Region (Czech republic) in the Past 25 Years. Anthropologie (Brno) 41, 3: 263-276'.
The group of 719 boys and girls aged 15.1 to 18.9 years were tested. Anthropometric examination and continual stress exercise testing up to maximum was used. The results were compared to the results of the similar sample of the young population of the same age which were published by Seliger and Bartùnìk in the year 1977 and with the results of the 5th All-state Anthropological Research of Children and Adolescents (1991) was done in the selected markers. The Student's t-test for testing the statistical significance was used. The sample included 424 boys and 295 girls. Tested group was taller in all age categories in the contrast to year 1977 and with the exception of 18 year-old girls, also is heavier than the control group. Both sexes in all age categories had a significantly less of body fat. The boys reached with the exception of the oldest age group a higher value of maximal oxygen uptake (VO2 max) the girls reached a higher value of VO2 max only in the category of the sixteen and seventeen year-olds. There were no important differences between both groups in the values per 1 kg of body weight (VO2 with the exception of the youngest group of girls. The boys had in average 30 % higher value of VO2 max than the girls. Higher physical fitness of our sample in comparison with the individuals of the same age of the control sample is mainly given by a higher lean body mass and total dimensions of the present population. In comparison with the results of the 5th National-wide Anthropological Survey of Children and Adolescents 1991 were not statistical differences found, except higher body weight and body mass index in 15 years old girls and boys. The differences between both samples disappear with age. The results of this research are according with the finding of other authors about slowing down a secular trend of increasing body height in the past few years. Results show a speeding up of growth in younger age categories, whereas the eighteen-year- old boys and girls have probably reached their maximum in their ontogeny in 1991.
