Despite various attempts at prevention, injury in downhill skiing continues to be a worrisome recreational problem. The purpose of this study was to test the effect of an instructional ski video on the behaviour and injuries of 763 downhill skiers. They were enrolled in two study groups, based on whether or not an instructional video had been shown in their bus on the way to a skiing resort. The video focussed on information regarding how to get started in downhill skiing and injury prevention. The outcome parameters, behaviour (binding test and adjustment), injury risk, type and consequence, were registered on the return trip 8 days later by a questionnaire. In the intervention group all outcome parameters changed significantly. The binding test was performed by 86% in the intervention group and by only 59% in the control group (P < 0.05). Adjustment of the bindings was done by 22% in the intervention group vs 14% in the control group. Regarding injury risk, 205 injuries were seen in 158 persons (20.7%) which is 26 injured skiers per 1000 skier-days and 33.6 injuries per 1000 skier-days. In the intervention group 16% of all skiers were injured vs 23% in the control group, yielding a reduction in injury risk of 30% (P < 0.05). Injuries caused by falls were seen in 12.6% in the intervention group vs 16.2% in the control group (P < 0.05). Injuries caused by collision were seen in 6% of the intervention group vs 12% in the control group (P < 0.05). The overall mean injury risk was 16 injuries per 1000 falls. Knee injuries made up 32.6% of the total. For inexperienced skiers the knee injury risk was significantly lower if the bindings had been tested (P < 0.05). Therefore, an instructional ski video can change the behaviour of downhill skiers and reduce the injury risk and consequences significantly.
尽管人们采取了各种预防措施，但高山滑雪中的受伤问题仍然是一个令人担忧的娱乐性问题。本研究的目的是测试一部滑雪教学视频对763名高山滑雪者的行为和受伤情况的影响。根据在前往滑雪胜地的途中，他们乘坐的巴士上是否播放过教学视频，将他们分为两个研究组。该视频主要聚焦于如何开始高山滑雪以及预防受伤的相关信息。8天后返程时，通过问卷调查记录了行为（固定器测试和调整）、受伤风险、类型及后果等结果参数。干预组的所有结果参数均有显著变化。干预组中86%的人进行了固定器测试，而对照组中只有59%（P<0.05）。干预组中有22%的人调整了固定器，对照组为14%。关于受伤风险，158人中有205人次受伤（20.7%），即每1000个滑雪者日有26名受伤滑雪者，每1000个滑雪者日有33.6起受伤事件。干预组中16%的滑雪者受伤，而对照组为23%，受伤风险降低了30%（P<0.05）。干预组中因摔倒导致的受伤发生率为12.6%，对照组为16.2%（P<0.05）。干预组中因碰撞导致的受伤发生率为6%，对照组为12%（P<0.05）。总体平均受伤风险为每1000次摔倒中有16起受伤事件。膝盖受伤占总数的32.6%。对于没有经验的滑雪者，如果进行了固定器测试，膝盖受伤风险会显著降低（P<0.05）。因此，一部滑雪教学视频可以改变高山滑雪者的行为，并显著降低受伤风险和后果。
