The incidence of injuries among youth soccer players (under age 16) participating in indoor soccer was 4.5 times that of youth players in outdoor soccer when calculated per 100 hours of team play, and 6.1 times greater when calculated per 100 hours of player game participation. Injuries were few among players under age 10 in either game, and the number of injuries increased with age in the older players. Medical assistance was required for 6.5% of the injuries among outdoor players and for 24.3% among indoor players. Overall, 66.6% of the injuries were the result of physical contact between players. No relationship was observed between the risk of injury and playing position, conduct of warm-up exercises, or the team having a licensed coach.
在按每100小时团队比赛计算时，参加室内足球的青少年足球运动员（16岁以下）受伤发生率是参加室外足球的青少年运动员的4.5倍；按每100小时球员比赛参与时间计算时，前者受伤发生率则是后者的6.1倍。在这两种比赛中，10岁以下球员受伤较少，而年龄较大球员的受伤数量随年龄增长而增加。室外球员受伤中有6.5%需要医疗救助，室内球员则为24.3%。总体而言，66.6%的受伤是球员之间身体接触所致。未观察到受伤风险与比赛位置、热身运动开展情况或球队有持证教练之间存在关联。
