Obviously there are massive benefits to physical activity and sport can be a massive part of that, but it can go horribly wrong as described. I was put off doing any activity by poor PE teaching at school, which just seemed like ritual humiliation to me. I struggle to motivate myself to exercise now and I wish we had done less competitive things. Even something like high jump, though not a team sport, seems pointless and potentially damaging. I can remember being totally unable to do it and would run up and just stop, which was obviously embarrassing. Why did I need to do that though? Surely there are better activities that are easier to succeed at that are more like to promote a love of physical activity - like dance/zumba etc.
Ds1 plays cricket in a team and has struggled with the parents to be honest. When he was captain he got loads of hassle from pushy parents, and now someone else is, their dad, who is also coach, just let his own dc and small number of others dominate every game. It got ridiculous and we were spending hours at places just for ds and others to neither bat nor bowl, at all. A few other parents spoke out and it's a bit better now, but it shows it does bring out the worst in some people. Not all, but some. Then we are told how grateful we need to be to these volunteers. Yes, I appreciate it wouldn't run without them but they should be able to do it in a fair way otherwise it becomes totally toxic and you begin to question the worth of it carrying on for the majority of the kids. Now he's old enough to play for the 4ths, which has a mix of adults, older kids and kids his own age and he says he is enjoying it more than ever as there are no pushy parents and he has found everyone really supportive. No doubt kids' teams can be a nightmare due to the attitudes of some parents.
And it's not just adults who can be awful. I think the kids at cricket have all been fine, though because his club is quite successful lots of private school boys with no links to the area have joined and aren't particularly friendly. That takes away the joy as well - when they are winning and these kids don't give a toss about the club itself. That's a problem with our club though, and not a universal one I know. Ds was also put off playing football at primary school because one of the older kids was allowed to coach and was utterly nasty and hyper-critical. As I said, it can bring out the worst in people and, while that can be managed and isn't a universal thing, it's annoying the way people harp on as if sport is an unfailing force for good that makes everyone resilient and caring and team-focussed and that simply isn't necessarily the case.
As a teacher, I also get irritated at the obsession with sport at school and rewards etc being dominated by those who have done well at sport and every other achievement more or less ignored. Our rewards system has a function where PE teachers can award 50 point, yet everyone else can award a maximum of 5 at any one time! Why can't I recognise an extraordinary essay/ expressive reading etc now and again? Why is it only sport that can be worthy of such a reward? And, yes, I have complained. I appreciate it's not like that everywhere, but it can be and it does more harm than good for those who aren't naturally sporty in terms of promoting a love of exercise.
