From: Using force data to self-pace an instrumented treadmill and measure self-selected walking speed
Convergence of walking speeds in self-paced treadmill tests. Walking speeds normalized by final estimated speed in a Self-Paced 2 min and b Self-Paced 150 m tests. Walking speed from individual trials are shown in colored lines. The mean and ±1 standard deviation across all trials are shown as a black line and gray shaded area. The solid and dotted vertical lines indicate the mean and mean plus one standard deviation of convergence time and distance
