BackgroundObesity is associated with higher foot loading during walking. The impact of this condition on running, however, has yet to be elucidated.Research questionThe purpose of this study was to examine the association between childhood obesity and plantar pressure distribution during running.MethodsForty-two volunteers aged 5 to 10 years took part in this cross-sectional study. Body mass index (BMI) was assessed for obesity classification. Peak plantar pressure was evaluated during running at self-selected speed using an Emed AT-4 pressure platform.Results and significanceBMI was correlated to peak pressure at whole foot (r = 0.340; p = .027), midfoot (r = 0.550; p < .001) and forefoot (r = 0.454; p = .003). Regarding other baropodometric parameters, obese children generated more forces during running compared to their leaner counterparts (all p < .050), except at the hallux. Also, obese children had a larger contact area under all the foot regions (all p < .050). These findings provide evidence that childhood obesity is associated with increased plantar pressure during running at self-selected speeds and support the concept that obese children are at higher risk of developing foot discomfort and pain.
