Winter swimming PPT 冬泳.pptxVIP

Winter swimming;Winter swimming is the activity of swimming during the winter season, typically in outdoor locations (open water swimming) or in unheated pools or lidos. In colder countries it may be synonymous with ice swimming, when the water is frozen over（结满了冰）. This requires either breaking the ice or entering where a spring prevents the formation of ice. It may also be simulated by a pool of water at 0?°C, the temperature at which water freezes. The International Ice Swimming Association requires that the water is colder than 5?°C for ice swimming competitions;In Eastern Europe and Russia winter swimming is part of the celebration of the Epiphany. Competitions for winter swimming also exist. Many winter swimmers swim with standard swimming costumes rather than with wetsuits or other thermal protection. Famous winter swimmers include Henri Kaarma, Ram Barkai, Lynne Cox and Lewis Gordon Pugh. ;Also, many locations in North America and Western Europe hold polar bear plunges（北极熊）, commonly to celebrate New Years Day, although participants are not expected to swim and generally most do not swim. ;Maintaining the hole in the ice（维持冰洞）;Most ice swimming places also use a specific heated carpet going from the locker rooms to the ice-hole， both to make walking to the hole more pleasant and for safety as otherwise the water dripping from returning swimmers would freeze and create a dangerously slippery surface to walk on.;National traditions;Ice swimming (avantouinti) on its own is especially popular in Estonia and Finland. There is an Avantouinti Society, and swimming holes are also maintained by other groups such as the Finnish skiing association (Suomen Latu). The Finnish Sauna Society maintains an avanto for sauna goers. 在爱沙尼亚和芬兰的冰泳 (avantouinti) 在其自身上是特别受欢迎。有一个 冰泳的社会，和游泳洞也由其他群体维持，例如芬兰滑雪协会 (Suomen Latu)。芬兰桑拿协会为桑拿常客维持一个冰洞。 Maintained：?[me?n?te?n] 是maintain的过去分词维持；保持to make sth continue at the same level, standard, etc. Goers: ?[?ɡo?r] 常去…的人a person who regularly go
