I have been asked to reply.
The Government have not commissioned any work comparing fitness levels of children who walk or cycle to school, to those who are driven.
Neither is any assessment currently made of children's fitness levels on a national scale. We do, however, measure children's physical activity levels in line with the chief medical officer's (CMO) recommendations that children aged 5 to 16 need at least 60 minutes of moderate intensity physical activity every day to be healthy. The Health Survey for England 2008 showed that 32 per cent. of boys and 24 per cent. of girls aged two to 15 were meeting the CMO recommendation.
