Abstract

Progresivnim kontinuiranim testom opterećenja na veslačkom ergometru analizirano je 125 veslača hrvatskog nacionalnog i internacionalnog ranga (dob- 23,43 ± 4,38 god; visina- 189,25 ± 5,73 cm; težina- 89,96 ± 9,28 kg; forsirani vitalni kapacitet (FVK)- 7,18 ± 0,91 l; %FSVT- 89,33 ± 2,78 %; HRmax- 192,11 ± 8,99 otk; HRVT- 171,57 ± 8,87 otk i wVT- 316,81 ± 37,93 W) kako bi se izračunao algoritam za procjenu parametara aerobnog energetskog kapaciteta (VO2max i RVO2max) na veslačkom ergometru uvrštavanjem varijabli koje su lako mjerljive i ne zahtijevaju sofisticiranu opremu.
Algoritmi koji su izračunati pokazali su da se parametrima koji su lako dostupni može s minimalnom greškom procjene objasniti 52% varijance varijable VO2max (r= 0,72; p< 0,01), te 37% varijance varijable RVO2max (r= 0,60; p< 0,01). Rezultat u relativnom maksimalnom primitku kisika očekivano objašnjava manji postotak varijance varijable zbog toga što postoje varijabilnosti u masi veslača, a ona posredično utječe na taj rezultat.
Koeficijenti korelacija koji su na visokoj razini između rezultata izmjerenih u laboratorijskim testovima i rezultata dobivenih izračunima algoritama omogućavaju korištenje algoritama u svakodnevnom treningu, te kontroli treniranosti veslača za procjenu rezultata u varijablama maksimalnog primitka kiskika-VO2max i relativnog maksimalnog primitka kisika- RVO2max.

Abstract (english)

By rowing ergometer test, 125 rowers of Croatian national and international rank (age - 23,43 ± 4,38 years; height - 189,25 ± 5,73 cm; weight - 89,96 ± 9,28 kg; forced vital capacity (FVK) - 7,18 ± 0,91 l;% FSVT- 89,33 ± 2,78 %; HRmax- 192,11 ± 8,99 otk; HRVT- 171,57 ± 8,87 otk and wVT- 316,81 ± 37,93 W) has been tested to calculate an algorithm for estimating aerobic energy capacity parameters (VO2max and RVO2max) on a rowing ergometer by including variables that are easily measurable and do not require sophisticated equipment. The calculated algorithms showed that the parameters that are easily available can explain with minimal estimation error, 52% of the variance of the variable VO2max (r = 0.72; p <0.01), and 37% of the variance of the variable RVO2max (r = 0.60; p <0.01). The result in the relative maximum oxygen uptake is expected to explain the lower percentage of variance of the variable because there is variability in the mass of the rower, and it indirectly affects that result. Correlation coefficients that are at a high level between the results measured in laboratory tests and the results obtained by algorithm calculations allow the use of algorithms in daily training, and control of rower training to assess results in the variables maximal oxygen uptake- VO2max and relative maximal oxygen uptake- RVO2max.
