Figure 6
Work and total oxygen consumption ( VO 2 ) at peak total efficiency ( ε Total ), ε Total and total VO 2 at peak work. Further quantification of the average relations shown in Figure 4B, D and F: ε Total at peak work ( A ), work at peak ε Total (B) and total VO2 at peak work ( C ) and at peak ε Total (D). Values represent the mean ± SE of n = 17 SHAM hearts and n = 16 STZ hearts. *P < 0.05, STZ versus SHAM. In B and C, the P values are 0.093 and 0.056, respectively.
