Good coaching is key to creating early positive experiences for children in sport and physical activity. It can completely change the trajectoroy of kid's lives: it can get kids active for life, or wreck thier enthusiasm for sport altogether. Good coaching also requires training. In one study,only 5% of kids who played for trained coaches quit the sport the enxt year; under non-trained coaches the attrition rate was 26%.
