Sažetak

Predmet ovog rada je ispitivanje pouzdanosti testa za procenu osnovnih kinematičkih i karakteristika sile vuče kod plivača primenom testa plivanja u mestu maksimalnim intenzitetom u trajanju od 60 sekundi. Uzorak je činila grupa od 10 kategorisanih plivača seniorskog uzrasta. Svi plivači su bili specijalisti za kraul tehniku plivanja na sprinterskim i srednjim distancama (50, 100, 200 i 400m). Testiranje je izvršeno pomoću tenziometrijske sonde sa pratećom hardverskosoftverskom podrškom metodom test - retest. Kinematičke karakteristike su bile predstavljene sa dve varijable (avgstroke60tstime prosek trajanja pojedinačnog zaveslaja i avghz60ts - realizovana frekvencija zaveslaja) dok su karakteristike sile vuče bile predstavljene sa pet varijabli (avgfmax60 ts - prosek maksimalne sile vuče (pikova) pojedinačnih zaveslaja, avgfmin 60 ts - prosek minimalne sile vuče pojedinačnih zaveslaja avgf60 ts - prosek sile vuče pojedinačnih zaveslaja, avgimpf60 ts - prosek impulsa sile vuče pojedinačnih zaveslaja i avgrfd60 ts - prosek vrednosti gradijenta prirasta sile vuče pojedinačnih zaveslaja. Na osnovu dobijenih rezultata može se zaključiti da je dati metod procene generalno validan na nivou Krombahove alfe = 0.8649 (86.49%), generalno reliabilan na nivou Spirman-Braunovog rtt = 0.9722 (97.22%) i generalno faktorski validan na nivou od 0.929 do 0.938 (92.8 do 93.8%), pa se može predložiti za dalju upotrebu u sportskoj praksi. U odnosu na posmatrane parcijalne pokazatelje tj. Pojedinačne varijable utvrđeno je da su varijable avgrfd60 ts avgstroke60 tstime, avghz60 ts, avgfmax 60 ts, avgfmin 60 ts i avgf60 ts statistički značajno validne u rasponu od 0.777 do 0.979, i pouzdane u rasponu od 0.782 do 0.979, respektivno. Za varijablu avgimpf60 ts u ovom istraživanju nije utvrđen dovoljan nivo ni validnosti - 0.518, ni pouzdanosti - 0.541. Kako je generalni nivo validnosti i pouzdanosti veoma visok i statistički značajan, pretpostavljamo da je nedovoljan nivo parcijalne validnosti i pouzdanosti varijable - avgimpf60 ts više posledica relativno malog uzorka (10 ispitanika) nego stvarnih mernih karakteristika date varijable.
