好玩好玩, 根据NSAA:
According to Dr. Jasper Shealy, professor emeritus at the Rochester Institute of Technology in Rochester, N.Y., who has studied ski related injuries for more than 30 years, the number of collisions accidents with other skiers or snowboarders accounts for only 6.4 percent of reported accidents. Dr. Shealy's research also confirmed that alpine skiers are three times more likely to be involved in a collision with other people than snowboarders.
为什么skier的collision比snowboarder多三倍呢? 从我们的体会来讲不是这样呀,美国和加拿大会有很大的不同吗? 而且skier眼睛向前,snowboarder有一面是看不到的。难道是因为skier速度快? 还是因为很大一部分snowboarder在park或者树林? 显然比起来park, groom的道上更容易collision. 如果说数据可靠的话,那要为snowboarder正名呢。
collision占inccident的6.4%, 说明大家主要还是防止撞大树,而不是防单板? 好像跟大家体会不同。
snowboarder's injuries are increasing, almost doubled in 10 years. from 3.xx to 6.xx per 1000 visits.
alpine ski 的 injury 是 2.6 per 1000 visits
是不是说兰山今晚1000人,按几率就会有10个受伤的? 同雪网50个人各滑20天,就有10个受伤的?好像也跟现实不太一样? |
