The purpose of this study was to investigate the effects of aging on gait parameters at two different speed conditions in Japanese females. This study involved 42 healthy Japanese females who were divided into three groups: (1) 14 younger females, mean age 22.3 ± 1.6 years, (2) 14 older females (65 to 75 years old), mean age 70.7 ± 1.8 years, and (3) 14 very old females (≥ 76 years old), mean age 78.2 ± 3.5 years. Various parameters were measured: basic gait parameters (speed of walking, right step length, left step length, step length, difference between right and left step lengths, ratio of step length to height, ratio of step length to lower-limb length, and cadence) and gait cycle parameters (time of swing phase, time of stance phase, time of one gait cycle, percentage of swing phase, and percentage of stance phase). The walking speeds in groups 1, 2, and 3 were 72 ± 5.4, 71.4 ± 7.3, and 69.7 ± 6.7 at the self-selected speed, and 91.3 ± 7.4, 86.2 ± 8.3, and 85.1 ± 9.1 m/min at the fast speed, respectively. In two-way repeated-measure ANOVA, all the parameters showed statistically significant effects of speed conditions (p<0.05), except the difference between right and left step lengths. Statistically significant effects of groups were found in right step length, left step length, step length, and difference between right and left step lengths (p<0.05). In addition, significant interactions between speed conditions and groups were found in the time of swing phase, time of stance phase, and time of one gait cycle (p<0.05). Under the self-selected speed condition among the three groups, posthoc pairwise Bonferroni-corrected comparison showed significant differences in right step length, left step length, step length, and difference between right and left step lengths (p<0.05). Under the fast speed condition, however, significant differences were only found in right step length, left step length, and step length (p<0.05).
