Abstract

Considering that body features interfere in motor performance, the aim of this study was to analyze the changes in spatial and temporal parameters of gait in obese, and non-obese children according to the gender.23 children intentionally selected participated in this study and they were distributed between two experimental groups according to their body mass index:
obese (OB, n=9) and normal (N, n=14). Ali the participants had written consent forms signed by their parents. Reflexive markers were attached on the following body landmarks of the right
foot: fifth metatarsal, malleolus lateral and calcaneus. The participants were asked to walk on an 8m rubber pathway at a preferred pace while their locomotor behavior were recorded using a video camera Panasonic (model NV - M9OOOPN S-VHS) in a sagittal plane. Using a MatLab routine, the following variables were collected: stride length (SL), stride length normalized by
height (SLN), stride duration (SD), stride velocity (SV), swing phase duration (SPD), and support phase duration (SUD). Data was statically analyzed using ANOVA with groups and gender as
factors. Results revealed that: group alone interfere on SLN and SD; gender alone affects SL, SLN and SV; group and gender affects SLN, SPD and SD. These results allowed us to conclude
that the increase in body weight can make changes in spatial and temporal parameters of children gait when gender is considered.
