Locomotion Variations of Arch Index and Interlimb Symmetry in Shod and Barefoot Populations

Table 1

Comparisons of arch index in left and right feet from standing to walking and running in shod and barefoot males.

Population			Standing	Walking	Running
Barefoot	LFAI (cm^2)	Mean	0.22^#	0.24^^	0.27^#^
		SD	0.04	0.04	0.04
	RFAI (cm^2)	Mean	0.23^#	0.25^^	0.28^#^
		SD	0.04	0.03	0.04
Shod	LFAI (cm^2)	Mean	0.22^&+	0.25^$&	0.29^$+

	RFAI (cm^2)	Mean	0.21^&+	0.25^$&	0.28^$+

Notes: LFAI: left foot arch index; RFAI: right foot arch index; SD: standard deviation; barefoot population: significant difference between standing and walking; ^#significant difference between standing and running; ^{^}significant difference between walking and running. Shod population: ^&significant difference between standing and walking; ⁺significant difference between standing and walking; ^$significant difference between walking and running ().
