Figures & data
Figure 1 The power duration relationships derived from data collected by Neder et al. (Citation[9]) from study of a group of 8 male COPD patients and a group of 10 age-matched healthy male controls. The curves were constructed from the average values of the critical power (CP) and the curvature constants (W') of the individuals in the two groups. Horizontal and vertical lines indicate the exercise durations (Tlim) that would be predicted in response to a constant work rate (WR) equal to 90% of the peak work rate in the two groups. Note that, despite a much lower peak work rate and lower critical power, the tolerated duration at 90% of peak work rate is much greater in the COPD group.
