Abstract

U sportskoj i medicinskoj dijagnostici koriste se različiti protokoli za mjerenje aerobnog kapaciteta sportaša. U sportovima gdje sama izvedba ovisi o visokoj aerobnoj sposobnosti sportaša najčešće se koristi progresivni test opterećenja. Cilj ovog istraživanja bio je utvrditi pouzdanost novog mjernog instrumenta za određivanje aerobne sposobnosti primjenom progresivnog testa opterećenja. Svrha istraživanja je svakako bila približiti ovakav način testiranja široj populaciji sportaša odnosno validacijom utvrditi pouzdanost ergometra te ga cjenovno približiti svim klubovima kako se ne bi trebale izdvajati velike svote novaca za odlazak u dijagnostičke centre kojih je vrlo malo. Istraživanje se provodilo na deset ispitanika studenata Kineziološkog fakulteta sveučilišta u Zagrebu. Korišten je progresivni test opterećenja na bicikl ergometru sa početnim otporom od 75W te povećanjem od 25W svakih 60 sekundi te održavanjem frekvencije okretaja pedala od 60 okt/min. Nakon provedenog istraživanja svi podaci su uneseni u MS Excel i obrađeni u programu Statistica for Windows. Mjere asimetrije (Skewness) i izduženosti (kurtosis) distribucije korištene su za provjeru osjetljivosti novog mjernog instrumenta. Normalnost distribucije provjerena je s pomoću Kolmogorov-Smirnov (KS) testa. Valjanost i pouzdanost je utvrđena pomoću T-testa. Koeficjent interkoleracije uzet je kao pokazatelj homogenosti varijabli proizašlih iz protokola provedenog na novokonstruiranom električnom biciklu. Nakon provedenog istraživanja dobiveni rezultati ukazuju na to kako su rezultati na novokonstruiranom električnom biciklu ergometru u velikoj korelaciji sa rezultatima na već postojećem ergometru što potvrđuje zadane hipoteze i cilj samog mjerenja.

Abstract (english)

Many different protocols are used in sports and medical diagnostics to measure the aerobic capacity of athletes. In sports where the performance itself depends on the high aerobic capacity of the athlete, a progressive load test is most often used. The aim of this study was to determine the reliability of a new measuring instrument for determining aerobic capacity using a progressive load test. The purpose of the research was certainly to bring this way of testing closer to a wider population of athletes, ies to determine the reliability of the ergometer by validation and bring it closer to all clubs so that large sums of money should not be set aside to go to diagnostic centers. The research was conducted on ten examinees of students of the Faculty of Kinesiology, University of Zagreb, with an average age of 22 ± 1. A progressive load test on a bicycle ergometer with an initial resistance of 75W and an increase of 25W every 60 seconds and a cadence maintenance of 60 oct / min was used. After the research, all data were entered into MS Excel and processed in the program Statistica for Windows. Measures of asymmetry (Skewness) and elongation (kurtosis) of the distribution were used to check the sensitivity of the new measuring instrument. The normality of the distribution was checked using the Kolmogorov-Smirnov (KS) test. Validity and reliability were determined using Factor Analysis. The intercoleration coefficient was taken as an indicator of the homogeneity of the variables derived from the protocol implemented on the newly constructed electric bicycle. After the research, the obtained results indicate that the results on the newly constructed electric bicycle ergometer are highly correlated with the results on the already existing ergometer, which confirms the given hypotheses and the goal of the measurement.
