Abstract (eng)
The aim of the present study was to investigate changes in performance in Austrian swimming with regard to the finishing times over freestyle distances (50 m, 100 m, 200 m, 400 m, 800 m, 1500 m) in the A-finals of the Austrian long track championships in the general class from the year 2000 up to and including 2020. Performance data from 837 women and 834 men were statistically evaluated using one-way ANOVA or, in the event that the normality was harmed, using the Kruskal-Wallis test. Significant differences within the examined period were found for women over 50 m freestyle (p < 0,001), 100 m freestyle (p = 0,001), 200 m freestyle (p = 0,001) and 800 m freestyle (p = 0,006). For men, significant differences were recorded over 50 m freestyle (p < 0,001), 100 m freestyle (p < 0,001) and 200 m freestyle (p = 0,008) over the period investigated. Therefore, no significant results could be determined over 400 m freestyle (p = 0,051) for women and over 400 m freestyle (p = 0,591) and 1500 m freestyle (p = 0,308) for men. To summarize, over the last 20 years women have been able to improve their performance in the 50 m, 100 m, 200 m and 800 m freestyle event, while men have achieved this in the 50 m, 100 m and 200 m free-style event.
