Brief Summary

A study is proposed to test whether adding additional referees to youth soccer matches may reduce the risk of injury to the children playing soccer. Publicly-open youth soccer games will be randomly assigned to have either one or three referees and videotaped. The videotaped games will then be watched to record risk-taking behavior by players, referee decisions, and other factors relevant to potential injury.
