Sažetak

Naše interesovanje u ovom radu usmereno je ka odgovoru na pitanje, da li će rezultati za procenu maksimalne aerobne moći biti značajno različiti ukoliko su dobijeni pomoću dva različita ergometra, i dva različita postupka koja se koriste u testiranju? Istraživanjem su obuhvaćena 64 mlada košarkaša starosti od 15 do 17 godina. Procena maksimalnog utroška kiseonika ustanovljena je Astrandovim testom na biciklergometru, i step-testom po fon Debelnu na visinama klupice od 30, 40 i 50.8cm. Od statističkih procedura upotrebljen je Spirmanov koeficijent korelacije ranga i Studentov T-test. Rezultati istraživanja ukazuju da se procenjene vrednosti maksimalnog kiseoničkog utroška ispitanika dobijene Astrandovim testom na biciklergometru i vrednosti dobijene na step-testu procenjene po von Döbeln-ovoj formuli značajno razlikuju. Kod 77% ispitanika procenjena je veća maksimalna kiseonička potrošnja step-testom. Razlike se mogu objasniti činjenicom da je fiziološki odgovor organizma na rad u step-testu drugačiji u odnosu na rad pri vožnji biciklergometra. Rad na step klupici u odnosu na bicikl ergometar, razlikuje se u odnosu na angažovane mišiće i njihove mase, pa je i opterećenje kardiovaskularnog sistema drugačije. To znači da organizam ne daje isti fiziološki odgovor na različite vrste opterećenja čak i kada je ujednačen po veličini obavljenog rada.
