| 释义 |
An Olympic-size swimming pool conforms to regulated dimensions, large enough for international competition. This type of swimming pool is used in the Olympic Games, where the race course is {{convert|50|m|ft|1}} in length, typically referred to as "long course", distinguishing it from "short course" which applies to competitions in pools that are {{convert|25|m|ft|1}} in length. If touch panels are used in competition, then the distance between touch panels should be either 25 or 50 metres to qualify for FINA recognition. This means that Olympic pools are generally oversized, to accommodate touch panels used in competition. An Olympic-size swimming pool is used as a colloquial unit of volume, to make approximate comparisons to similarly sized objects or volumes. It is not a specific definition, as there is no official limit on the depth of an Olympic pool. The value has an order of magnitude of 1 megaliter (ML).[1] SpecificationsFINA specifications for an Olympic-size pool are as follows:
There must be two spaces {{convert|2.5|m|abbr=on}} wide outside lanes 1 and 8 (in effect, two empty lanes).[2] The length of {{convert|50|m|ft|0}} must be between the touch pads at the end of each lane, if they are used.[2] If starting blocks are used, then there must be a minimum depth of {{convert|1.35|m|ft}} from between {{convert|1.0|m|ft|0}} from the end of the pool to at least {{convert|6.0|m|ft|0}} from the end of the pool. At all other points, the minimum depth is {{convert|1.0|m|ft|0}}.[2] If the pool is used for Olympic Games or World Championships, then the minimum depth is increased to {{convert|2.0|m|ft|0}}.[2] {{clear}}At FINA's 2009 Congress, rules were approved for 10-lane courses for competition, as an alternative to the more traditional 8-lane course. HistoryThis version of the Olympic-sized swimming pool debuted in the 2008 Beijing Summer Olympics. Beforehand, the Summer Olympics featured the more traditional 8-lane course with a depth of roughly seven feet[3], now the minimum depth requirement. This new Olympic-sized swimming pool was the host of 25 broken world records. AdvantagesThe new Olympic-sized swimming pool was designed to provide advantages to assist the swimmers. The first being the increase in the amount of lanes. Increasing the lane count from eight to ten gave the swimmers a "buffer lane," designed to siphon the waves generated by the swimmers allowing less resistance against the swimmers.[3] The extension of the depth of the pool gives swimmers another advantage, assisting the lane lines dissipate the water churning from the swimmers, creating less hydrodynamic drag for the swimmers.[3] See also
