Variation in physical activity lies with the child, not his environment: evidence for an |[lsquo]|activitystat|[rsquo]| in young children (EarlyBird 16)

摘要

Objective:There is currently wide interest in the physical activity of children, but little understanding of its control. Here, we use accelerometers to test the hypothesis that habitual activity in young children is centrally, rather than environmentally, regulated. By central regulation we mean a classic biological feedback loop, with a set-point individual to the child, which controls his/her activity independently of external factors.
