VO2max estimado por equações preditivas apresenta baixa concordância com o obtido pelo padrão ouro - teste cardiopulmonar.

Abstract

The aim was to evaluate the concordance between measurements of VO2max obtained by exercise cardiopulmonary test (gold-standard) vs. that obtained by predictive equations. Men (21-55 years-old) were grouped into Resistance training (RT; n=31), long-distance runners (R; n=28) and non-exercise practitioners (C; n=35). Five equations were tested, one of them made from Brazilian sample. The concordance was evaluated by Bland-Altman, and correlation analysis by Pearson's coefficient (r). The r between gold-standard vs. equations ranged 0.27 to 0.75, with p<0.05 for the most analysis, however, with low concordance. Regarding the equation obtained in Brazilians, the values with lower concordance were, following the order: C, RT and R. In relation to others equations, again with lower concordance, the order was R, RT and C. The worst estimates were to higher VO2max values, mainly for >40 mL.kg-1.min-1. In conclusion, the predictive equations tested generate low concordance when compared to VO2max gold-standard test, mainly for VO2max>40 mL.kg-1.min-1.
