At the same time, though, courts have refused to apply the defense of assumption of risk when educators failed to provide adequate supervision such as where a competitor in a track and field meet was struck by an errant discus while standing in a safe zone; a student was
injured during an indoor (American) football practice when he slipped on a wet gym floor where coaches failed to provide proper supervision or after another player was
injured due to the lack of supervision at a practice; coaches did not warn a student sufficiently about the dangers of diving into a pool; coaches conducted a track practice in a high
school hallway that unreasonably increased a student's risk of injury; and a coach lacked enough experience to provide adequate supervision to avoid injury to a
cheerleader.
