Abstract
BACKGROUND: Obesity is associated with higher foot loading during walking. The impact of this condition on running, however, has yet to be elucidated. RESEARCH QUESTION: The purpose of this study was to examine the association between childhood obesity and plantar pressure distribution during running. METHODS: Forty-two volunteers aged 5-10 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 SIGNIFICANCE: BMI 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.
