Analysis of the trend of results development in the disciplines of breaststroke technique for swimmers at World championships

Breaststroke, as one of the four basic swimming techniques, has undergone many changes in styles and rules: from lateral breaststroke, dolphin arm movement, swimming below the surface of the water, dolphin kicks to the last version of breaststroke technique with oscillating body position and very strict rules. The aim of this research is to analyze the development trends and to determine the curve of the development of results in the disciplines of breaststroke technique for female swimmers at the world championship from 1998 to 2017. The sample consists of female swimmers from different countries who have competed in the finals of the World championship in the selected period. The variables in this study are the disciplines 50 m breaststroke, 100 m breaststroke, and 200 m breaststroke. The data were collected in the form of official results from International Swimming Federation (FINA) website. The collected data were processed by the method, algorithm, and program for trend analysis with the software package Statistica 13. The polynomial regression analysis analyzed the trend of development of the average final results. For the analyzed races, single-dimensional changes in the status of swimmers were shown over the years, during which a change in one quantitative variable is registered over a period of time. An analysis of the trend of development showed a linear increase in results of breaststroke disciplines for female swimmers at world championships, which is an indicator of the application of new rules, technological advances, and adequate long-term sport preparation and provides coaches and national federations with information on the forecasted results for the next competitive year.
