The physical and athletic condition of today's school youth receives a high attention, especially in public. The aim of this work is therefore to find out in which direction the sport performances of pupils aged between eleven and eighteen years from 2009 to 2016 developed. In order to investigate the sporting performance, the results in the disciplines 60m-sprint, long jump, distance throw, shot put and the overall score of 1518 girls and boys who started at the athletics school championships in the region of Wolfsberg were examined for differences. In addition, the results were compared with the sport performances of 1204 pupils from four other regions (Graz, Bruck-Mürzzuschlag, Voitsberg, Spittal). This comparison also shows how the athletic performances of pupils who live in the country differ from pupils who live in the city. From 2009 to 2016, only the fifteen to sixteen-year-old girls have improved the total score points significantly by 13.29 percent (p < 0.001). In the remaining age groups, the overall score differences were not significant. In addition, both sexes could significantly improve the 60 m sprint times in almost all age groups. On the other hand, significant performance reductions were found in the disciplines of jumping, distance throwing and shotgun. In all disciplines as well as in all grades from eleven to eighteen years, significant gender differences were observed. The comparison between pupils from the city and pupils from the country shows, that the eleven to twelve and thirteen to fourteen-year-old girls and boys from rural districts have achieved significantly better performances than the girls and boys of the same age from the urban environment. On the other side, at the Age of fifteen to sixteen years, the boys from the city showed significantly stronger performances.
