Finding comparable modern data for other sports isn’t easy. But here’s one interesting example from 1998. In a study of sporting injuries amongst 6-15 year olds in New Zealand, it was found that young netball players sustained 13 injuries per 1,000 player hours. Of course, an hour of school sport doesn’t equate to the average skiing day – but it’s probably not far off, given how much sitting about on chairlifts we do.
