The purpose of this study was to examine the differences in lower extremity kinematics and muscle activation patterns in normal weight and overweight children during stationary exercises at submaximal intensity. Twenty-five children (10-13 years) were recruited and classified as overweight (OW) and normal-weight (NW). Electromyography, the ratings of perceived exertion (RPE) and range of motion (ROM) of lower extremity joints were collected during stationary exercises. ANOVAs compared muscle activation, ROM and RPE between groups, and exercises. Compared to NW, OW experienced significantly greater RPE and muscle amplitude in all muscles apart from VL during stationary exercises. Children with greater mass adopt a more active neuromuscular strategy in order to provide greater stability and propulsion during stationary exercises.
