Figure 2From: Exercise on Prescription: trial protocol and evaluation of outcomesThe Wmax-VO2max relationship. The maximal work capacity (Wmax) was plotted against the maximal oxygen uptake (VO2max), and linear regression was performed. The relationship was highly linear (VO2max = 13.895 * Wmax + 151 ml O2/min, R2 = 0.9108, p < 0.0001), but prediction intervals were wide (mean ± 1.96 SD, 452 ml O2/min).Back to article page
