From: Measuring the Energy of Ventilation and Circulation during Human Walking using Induced Hypoxia
Observed ΔEE plotted against that predicted ΔEE from the least squares regression with VE and HR: ΔEE = 0.44ΔVE + 0.24ΔHR; see text. Line indicates y = x. This predictive fit model for data was calculated using the hypoxia-speed conditions with only positive ΔEE values (filled circles), but excluding the hypoxia-speed conditions with negative ΔEE values (open circles).
