Walking speed-related changes in stride time variability: effects of decreased speed

Table 1 P-value of repeated measures analysis of variance (ANOVA) (n = 1280 steps) estimating the effects of a decrease in self-selected walking speed on mean value, standard deviation and coefficient of variation of stride time, adjusted for subject's effect (n = 29), number of trials per walking condition and left-right step asymmetry

	Effect
Stride time	Decrease in preferred walking speed	Subject	Trials*	Left-right step asymmetry†	R-squared
Mean value	<0.001	<0.001	0.534	0.971	0.612
SD	<0.001	<0.001	0.177	0.150	0.481
CoV	<0.001	<0.001	0.691	0.288	0.293

SD: standard deviation,
CoV: Coefficient of variation expressed in percentage and calculated from the formula: [(Standard deviation/Mean value) × 100],
*: Number of trials per walking condition coded in three level (0 = first trial, 1 = second trial, 2 = third trial)
†: Right and left step coded as a binary variable (0 = Right, 1 = Left)
