The purpose of this study was to investigate associations between peak magnitudes of raw ac-celeration (g) from wrist- and hip-worn accelerometers and ground reaction force (GRF) variables in a large sample of children and adolescents. 269 participants (127 boys, 142 girls; age: 12.3 ± 2.0yr) performed walking, running, jumping (5cm) and single-leg hopping on a force plate. A GENEActiv accelerometer was worn on the left wrist and an Actigraph GT3X+ was worn on the right wrist and hip throughout. Mixed-effects linear regression was used to assess the relationships between peak magnitudes of raw acceleration and loading. Raw acceleration from both wrist and hip-worn accelerometers was strongly and significantly associated with loading (all p’s
