Growth and aging

Document Type



The aim of this study was to compare the footfall pattern (FP) in different age groups of preschool children while they ran in standard running shoes (SRS) and barefoot. Forty-eight children aged 3-6 years participated in the study and were split into 4 age groups (n=12). All children performed a simple running game (based on the shuffle run) in SRS and barefoot. The length of the runway was adjusted for each age group. Kinematic and kinetic data were collected using 3-D motion capture system. We analyzed strike index (SI) and sagittal plane ankle angle (AA) at initial contact (IC) from 6 successful running trials for each child in each condition. We found differences between conditions in both SI (p=0.000, η2=0.448) and AA (p=0.000, η2=0.259) respectively, but we did not find any differences among age groups. Moreover, we found an interaction between age and conditions in AA (p=0.019, η2= 0.201). In preschool children, FP changed differently in certain age groups according to the footwear condition.
