... I recently had placement from university and did some work in my old school and some children will even just sit PE out and not do it!? When I was at school which was not long ago at all everyone in my class wanted to do PE and it was something to look forward to! Even if they had forgot their kit they would raid the school football team or rugby team for some kit. ...
I have rather different memories of sport at school. It was OK in the summer, but I hated having to go out and play hockey in the winter. Fortunately we didn't do cross-country (living in a large town), I'm sure it would have put me off running for ever.
PE was compulsory, no sitting it out allowed, so once I got to about 14 my friends and I would bunk off PE.
You can only encourage kids to try sport. If they like it, they'll want to carry on, but if you force them they will often hate it on principle!
I think there will be a short period of huge enthusiasm, followed by a tailing off. Schools which have sold their playing fields can't get them back, and there is little money to put into equipment.
