Sažetak
The aim of this study was to validate four commonly used tests (Astrand-Ryhming, Bruce, Balke andPWC150) for indirect maximum oxygen uptake (VO2max) prediction and to assess their usage in the case of soccerplayers. Sixteen male subjects (age = 27.8 ± 3.8 y, height = 182.8 ± 4.7 cm and body mass = 81.5 ± 8.5 kg)participated in this study. Four observed tests were compared with direct VO2max assessment which wasperformed as breath-by-breath gas analysis during graded treadmill protocol until exhaustion. The Astrand- Ryhming and PWC150 tests were performed on a stationary bike while the Bruce and Balke tests were conductedon a motorized treadmill. The methods of statistical analysis and comparison used were Bland-Altman plotanalysis, regression analysis, the coefficient of variation and one way ANOVA. Our results revealed noagreement among measurement techniques and mean differences in all four protocols. The relationship wasmodest but statistically significant in the case of Bruce protocol (R2 = 32 %, p ≤ 0.05). We conclude moderatereliability to be sufficiently satisfactory for the observed population and can be used under given circumstances.
