Metabolic cost and mechanical work of walking in a virtual reality emulator.

"after inspection of stereophotogrammetric data mechanical variables were excluded for five acquisitions in which the harness for the multidirectional treadmill affected the quality of the marker data (supplementary data 1).; the relation between c and speed was best fit by a second-order polynomial in the form y = 20 2-27 5 x + 15 8 x 2 ( r 2 = 0 52; p b1 = 0 0004 p b2 = 0 0070; supplementary data 2) with a minimum at ~ 0 9 m s -1 .; supplementary data 2 shows all the regression results and the 95% confidence intervals for the fit parameters.; data availability individual-level metabolic mechanical and kinematic data can be found in supplementary data 1."
