Comparison of gait variables at two gait speed conditions in the Non-FoF and FoF groups

Gait variables	Non-FoF group, n = 202		FoF group, n = 58
	Normal gait	Fast gait	Normal gait	Fast gait
Walking speed, m/s	1.4 ± 0.2	1.8 ± 0.2**	1.3 ± 0.2‡	1.6 ± 0.2**‡
STV, %	1.9 ± 0.9	2.1 ± 1.1	2.3 ± 1.1†	1.9 ± 0.9*
HR-VT	3.4 ± 0.9	3.5 ± 0.9	3.2 ± 0.9	3.4 ± 1.1
HR-ML	2.3 ± 0.7	2.6 ± 0.8**	2.1 ± 0.7	2.4 ± 0.7*
HR-AP	3.7 ± 1.1	4.0 ± 1.1**	3.6 ± 1.0	3.7 ± 1.2

Values are means ± standard deviation. Normal gait is a gait condition in which subjects were asked to walk at a self-selected preferred gait speed. Fast gait is a gait condition in which subjects were asked to walk at a self-selected fast-gait speed
