Abstract: The aim of this study was to quantify the habitual physical activity level (HPA) following school and free days, and to the analyze the relations with the physical fitness level (PF) in French prepubertal children. Thirty-nine children (15 boys and 24 girls), aged 8 to 12 years old, were involved in the study. They performed six field tests, some of which comprised to the European physical fitness test battery (EUROFIT). Children HPA was recorded during a 7-day period, between 7 am and 9 pm, and the time spent above a HPA threshold corresponding to moderate to vigorous intensity (> 3 Mets) was calculated. In prepubertal children, HPA was significantly higher during school days, but not related to the different components of PF
