U ovom istraživanju na uzorku od 36 ispitanika podjeljenih na tri subuzorka od 12, plivača učesnika otvorenog prvenstva Bosne i Hercegovine 2018 i 2017, godine, kao i mitinga na 25 Međunarodnom memorijalu „Ante Lambaša“ u Beogradu 2017. godine, uzetu su podaci sa zapisnika plivačkih takmičenja prolaznih vremena, kao i krajni rezultati plivanja slobodno na 400 metara.Istraživanje je sprovedeno s ciljem utvrđivanja uticaja dionica plivanja (50, 100, 150, 200, 250, 300 i 350) metara, kao prediktorskog seta varijabli i uticaj na kriterijsku varijablu rezultatske uspješnosti plivanja 400 m slobodno. Dobijeni rezultati regresione analize ukazuju na statistički značajnu povezanost seta varijabli (50, 100, 150, 200, 250, 300 i 350) na kriterijsku varijablu plivanja 400 slobodno.Vrijednost koeficijenata multiple korelacije koji determinišu uticaj setat prediktorskih varijabli (50, 100, 150, 200, 250, 300 i 350) na kriterisku varijablu 400 m plivanja slobodno iznosi: za 50 m 42%, 100 m 52%, 150 m 65%, 200 m 67%, 250 m 67%, 300 m 68%, 350 m 43% zajedničke varijanse plivača Mitinga Olimp Banja Luka u 2018. godini.Vrijednost koeficijenata multiple korelacije koji determinišu uticaj setata prediktorskih varijabli (50, 100, 150, 200, 250, 300 i 350) na kriterisku varijablu 400 m plivanja slobodno iznosi: za 50 m 58%, 100 m 59%, 150 m 71%, 200 m 70%, 250 m 71%, 300 m 70%, 350 m 41% zajedničke varijanse plivača Mitinga Olimp Banja Luka u 2017. godini. Vrijednost koeficijenata multiple korelacije koji determinišu uticaj setata prediktorskih varijabli na kriterisku varijablu 400 m plivanja slobodno iznosi: za 50 m 58%, 100 m 65%, 150 m 62%, 200 m 84%, 250 m 67%, 300 m 89%, 350 m 76% zajedničke varijanse plivača Mitinga „Memorijal Ante Lambaša“ 2017. godini u Beogradu.Zaključak. Setat prediktorskih varijabli (50, 100, 150, 200, 250, 300 i 350) plivanja slobodno ima značajan procenat uticaja na kriterisku varijablu 400 m slobodno kod plivača mitinga na 25 Međunarodnom memorijalu „Ante Lambaša“ u Beogradu 2017. godine Srbija u odnosu na isti kod plivača učesnika otvorenog prvenstva Bosne i Hercegovine 2018 i 2017, godine.

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.
