The feet are the main sources for human body sustentation, and the distribution of body mass occurs according to the needs of mechanical adaptation. Moreover, childhood obesity can cause ostheoarticular changes through over mass and decreasing of corporal stability. This study aimed to analyze the distribution of plantar pressure of female children (aged 6-10 years). The children were divided into three groups: control, overweight and obese, according to their Body Mass Index (BMI). The footprints were analyzed by FootWork platform and divided into three parts: the forefoot, midfoot and hindfoot. The average values of plantar pressure were compared in order to investigate the differences between the three classes of children.
