SUCCESS RATE OF RESULTS IN SWIMMING 400m FREESTYLE DEPENDANT OF TIME TRIALS BY SECTIONS

For the purpose of this research, sample of 36 participants was divided into three sub-samples of 12swimmers, participants in Open Championship of Bosnia and Herzegovina in 2017 and 2018, as wellas rally at 25th International memorial race “Ante Lambaša“ in Belgrade in 2017. Data was obtainedfrom entries for time trials as well as final results of competition in 400m freestyle swimming. Researchwas conducted with the aim of establishing the influence of sections (50m, 100m, 150m,200m, 250m, 300m and 350m) as predictor set of variables and influence on criterion variable ofsuccess rate of results in 400m freestyle swimming. Results obtained using the regression analysislead to conclusion that there is statistically significant connection between the set of variables (50m,100m, 150m, 200m, 250m, 300m and 350m) and criterion variable of 400m freestyle swimming.Values of coefficient of multiple correlation which determine the influence of the set of of predictorvariables (50m, 100m, 150m, 200m, 250m, 300m and 350m) to criterion variable of 400m freestyleswimming are respectively: for 50 m 42%, 100 m 52%, 150 m 65%, 200 m 67%, 250 m 67%, 300 m68%, 350 m 43% of the common variance of swimmers who took part in rally “Olimp Banja Luka” in2018.Values of coefficient of multiple correlation which determine the influence of the set of of predictorvariables (50m, 100m, 150m, 200m, 250m, 300m and 350m) to criterion variable of 400m freestyleswimming are respectively:for 50 m 58%, 100 m 59%, 150 m 71%, 200 m 70%, 250 m 71%, 300 m70%, 350 m 41% of the common variance of swimmers who took part in rally “Olimp Banja Luka” in2017.Values of coefficient of multiple correlation which determine the influence of the set of of predictorvariables (50m, 100m, 150m, 200m, 250m, 300m and 350m) to criterion variable of 400m freestyleswimming are respectively:for 50 m 58%, 100 m 65%, 150 m 62%, 200 m 84%, 250 m 67%, 300 m89%, 350 m 76% of the common variance of swimmers who took part in rally 25th Internationalmemorial race “Ante Lambaša“in 2017 in Belgrade.Conclusion: set of predictor variables (50m, 100m, 150m, 200m, 250m, 300m and 350m) of freestyleswimming has significant percentage of influence to criterion variable 400m freestyle swimming forswimmers who took part in rally 25th International memorial race “Ante Lambaša“ in Belgrade in2017 in Seerbia when compared to the same one for swimmers who took part in Open Championshipof Bosnia and Herzegovina in 2017 and 2018.
