在历届水上救生员培训工作中,往往会遇到这样的学员:在游蛙泳、反蛙泳、侧泳、潜泳和踩水时用的都是“狗爬”腿。这样的学员在考核中往往不能过关。错误的根源就是不会用蛙泳腿完成以上五种救生员基本游泳技术。 Trainees in the previous life-long training work, often encounter such trainees: swim breaststroke, anti-breaststroke, side-swimming, diving and treading water are used when the “dog crawling” legs. Such students often can not pass the examination. The root cause of the mistake is that the above five lifeguard basic swimming techniques will not be accomplished with the breaststroke leg.
