Figure 4From: Prevalence of cardio-respiratory factors in the occurrence of the decrease in oxygen uptake during supra-maximal, constant-power exercise Relationship between the magnitude of the decrease in stroke volume (SV) and the resting forced expiratory volume in 1 s (FEV 1 ). FEV1 (L): forced expiratory volume in 1 s, SV change (%): stroke volume expressed as a percent of peak value (r = 0.73, P < 0.01), n = 11. The broken lines indicate the 95% confidence intervals.Back to article page
