[Physical activities in "sick" children, sports on prescription].

The medical profession seems to be more and more convinced of the beneficial effects to the child elicited by a sports activity at any age not only as morphological adaptation, but as psychological improvement too.

The general practitioner therefore should not prohibit going for sports.
