Background/Purpose: Physical activity is commonly prescribed to reduce childhood obesity. However, due to differences in mechanics during low-impact activities, such as walking, obese children may be more prone to negative physical complications during high-impact activities, such as running. Therefore, this study analyzed the mechanical differences in running mechanics between healthy weight (HW) and overweight/obese (OV/OB) children. We hypothesized that when compared to HW children, OV/OB children would display higher vertical loading, greater joint moments and greater joint angular impulses during running. We also expect decreased sagittal plane range of motion and increased frontal plane range of motion of the hip, knee, and ankle joints in the OV/OB group during running. Methods: Ground reaction force (GRF) and joint kinematic data were collected for 42 children (25 HW, 17 OV/OB) while they ran across an implanted GRF platform at a given speed of 3.5 ± 5% m/s. Spatial-temporal and joint kinetic data (ankle, knee, & hip) were also determined. A one-way ANOVA was used to compare group differences for all variables of interest (p
