Figure 1

Measured vs estimated maximal oxygen uptake (VO _2max ). Correlations between measured VO_2max and VO_2max estimated with the Fox-walk test (A-B), expressed in l/min (left) and ml · kg⁻¹ · min⁻¹ (right). Correlations between measured VO_2max and VO_2max estimated with the Åstrand test corrected for age (C-D) and corrected for maximal HR (E-F), expressed in l/min (left) and ml (right). The line of identity is plotted in the figures (n = 27).
