RESUMO

The literature suggests that there are large changes in gait patterns with progression speed. This study aimed to examine the differences in variables spatiotemporal during the walking at three different speeds (slow, self-selected and fast) among three age groups of children. Healthy children (n=33) were distributed in the following groups: 3-4 years, 5-6 years and 7-8 years. Spatio-temporal data were analyzing using absolute and normalized values (Hof ,1996). To verify differences between groups at different speeds was used ANOVA one-way and Tukey HSD post hoc test with level of significance set at 0.05. There was no significant difference between age groups at slow, fast or normal speeds when considered normalized speed. There were significant differences between groups of 3-4 and 7-8 years of age for absolute values at normal speed for cadence. For normalized cadence was found significant differences between the groups 3-4 and 7-8 years at slow speed and between 3-4 group and 5-6 and between 3-4 and 7-8 years groups at normal speed. In the fast speed there were also significant differences between these same groups for the values of normalized cadence. Significant differences were found among the most age groups both at slow, normal and fast speed when considered absolute step length but it was not observed for normalized step length. Absolute temporal values of slow, normal and fast walking showed that there is a decline in absolute values when speed increases. When relative temporal parameters are observed we can identify the same strategy to increase a velocity for all age groups: higher single stance time and balance time.
