谢谢小C代发贴. 我知道CROSSNA已有女生在学SNOWBOARDING(单板). 我的单板已可以顺畅滑行WHISTLER的蓝道和浅黑道啦. 单板比双板好玩，省力，更过瘾，难怪它倍受青少年喜爱。下面 顺便摘录点滴单板常识.
"单板起源於20世紀1960年代初的美國，當時，有一位美國父親把兩塊的滑雪板綁在一起，偶然中就發明了由雙腳踩在同一塊滑雪板的「新式滑雪板」。 這種滑雪方式雖然最初被視爲「另類運動」，但僅短短一年就流行於全國，並且傳播至歐洲各國。在世界各地中，這種「另類運動」被改裝成不同的運動。1980年代，單板滑雪風靡起來，出現各地區性、國際性的比賽，如美國就於1982年舉辦了第一次的全國賽，1年之後，世界錦標賽賽更出現".
"Safety and precautions
Like some other winter sports, snowboarding comes with a certain level of risk.
The injury rate for snowboarding is about four to six per thousand persons per day, this is around double the injury rate for alpine skiing. Injuries are more likely amongst beginners, especially those who do not take lessons with professional instructors. A quarter of all injuries occur to first-time riders and half of all injuries occur to those with less than a year of experience. Experienced riders are less likely to suffer injury, but the injuries that do occur tend to be more severe.
Two thirds of injuries occur to the upper body and one third to the lower body. This contrasts with alpine skiing where two thirds of injuries are to the lower body. The most common point of injury is the wrists – 40% of all snowboard injuries are to the wrists and 24% of all snowboard injuries are wrist fractures. There are around 100,000 wrist fractures worldwide among snowboarders each year.[18] For this reason the use of wrist guards, either separate or built into gloves, is very strongly recommended. They are often compulsory in beginner's classes and their use reduces the likelihood of wrist injury by half. In addition it is important for snow boarders to learn how to fall without stopping the fall with their hand by trying to "push" the slope away, as landing a wrist which is bent at a 90 degree angle increase the chance of it breaking. Rather, landing with the arms scratched out (like a wing) and slapping the slope with the entire arm is an effective way to break a fall. This is the method used by practitioners of Judo and other martial arts to break a fall when they are thrown against the floor, by a training partner.
The risk of head injury is two to six times greater for snowboarders than for skiers and injuries follow the pattern of being rarer, but more severe, with experienced riders. Head injuries can occur both as a consequence of a collision and when failing to carry out a heel-side turn. The latter can result in the rider landing on his or her back and slamming the back of his or her head onto the ground, resulting in an occipital head injury. For this reason, helmets are widely recommended. Protective eye-wear is also recommended as eye injury can be caused by impact and Snow blindness can be a result of exposure to strong ultra-violet light in snow-covered areas. The wearing of ultra-violet-absorbing goggles is recommended even on hazy or cloudy days as ultra-violet light can penetrate clouds.
Unlike ski bindings, all snowboard bindings are not designed to release automatically in a fall. The mechanical support provided by the feet being locked to the board has the effect of reducing the likelihood of knee injury – 15% of snowboard injuries are to the knee, compared with 45% of all skiing injuries. Such injuries are typically to the knee ligaments, bone fractures are rare. Fractures to the lower leg are also rare but 20% of injuries are to the foot and ankle. Fractures of the Talus bone are rare in other sports but account for 2% of snowboard injuries – a lateral process talus fracture is sometimes called "snowboarder's ankle" by medical staff. This particular injury results in persistent lateral pain in the affected ankle yet is difficult to spot in a plain X-ray image. It may be misdiagnosed as just a sprain, with possibly serious consequences as not treating the fracture can result in serious long-term damage to the ankle. The use of portable ultrasound for mountainside diagnostics has been reviewed and appears to be a plausible tool for diagnosing some of the common injuries associated with the sport.
Four to eight percent of snowboarding injuries take place while the person is waiting in ski-lift lines or entering and exiting ski lifts. Snowboarders push themselves forward with a free foot while in the ski-lift line, leaving the other foot (usually that of the lead leg) locked on the board at a 9–27 degree angle, placing a large torque force on this leg and predisposing the person to knee injury if a fall occurs. Snowboard binding rotating devices are designed to minimize the torque force, Quick Stance being the first developed in 1995.They allow snowboarders to turn the locked foot straight into the direction of the tip of the snowboard without removing the boot from the boot binding."
