- Mean = estimated mean outcome value at specific walking speed; SE = standard error of the estimated mean; BPV = Between-participant variability around the mean (expressed as standard deviations). These estimates were obtained from models similar to those presented in Table 3 with speed centered at the various calibration-trial walking speeds (3.5, 4.5, 5.5, and 6.5 km.h−1) and with a different calibration-method reference category
