The purpose of this study is to discuss the legal issues on drug, assault, sexual violence, and risk management that athletic coaches should keep in mind and to provide them with a guideline on how to deal with the issues. The guideline that this study proposes for the issues is as follows. First, unless they are qualified officially, athletic coaches should not recommend any drug to players or not implicitly acknowledge players drug use because coaches might be responsible for the players injury or death by their drug use. Second, athletic coaches should keep in mind that corporal punishment for the players by them will be recognized as a legitimate action only when it is performed in the educationally inevitable situation, when its way and degree are not exceeded a permitted limit, and when it does not conflict with the generally accepted values of the society. Third, the government should amend the current law making it possible not only to register a tougher punishment on sexual predators but also to provide better protections and compensations for the victims. The Office of Education, schools, and Korea Sports Council should develop more effective tools to monitor athletic coaches in order to decrease the possibility of sexual violences. In addition, because dormitory lodging for players is providing a hotbed of sexual violences, it is recommended that it should be gradually removed. Last, the best way to protect athletic coaches from the lawsuit against risk management is to thoroughly perform the duty of care that they are supposed to do. Athletic coaches should prepare risk management in terms of the characteristics of sports, health condition of players, responsibility of duty, and facility.
