Olympic-size swimming pool


An Olympic-size swimming pool conforms to regulated dimensions that are large enough for international competition. This type of swimming pool is used in the Olympic Games, where the race course is in length, typically referred to as "long course", distinguishing it from "short course" which applies to competitions in pools that are 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 mega liter.

There must be two spaces wide outside lanes 1 and 8. The length of must be between the touch pads at the end of each lane, if they are used. If starting blocks are used, then there must be a minimum depth of from between from the end of the pool to at least from the end of the pool. At all other points, the minimum depth is. If the pool is used for Olympic Games or World Championships, then the minimum depth is increased to.
long course swimming pool standard.
At FINA's 2009 Congress, rules were approved for 10-lane course for competition, as an alternative to the more traditional 8-lane course.

History

This 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, now the minimum depth requirement. This new Olympic-sized swimming pool was the host of 25 broken world records.

Advantages

The new Olympic-sized swimming pool was designed to provide advantages to assist the swimmers, the first being the increase in the number of lanes. Increasing the lane count from eight to ten gives the swimmers a "buffer lane", helping to absorb waves generated by the swimmers' movements, allowing for less resistance against the swimmers. Moreover, increasing the depth of the pool further gives swimmers another advantage, as the added depth assists the lane lines in dissipating water churn from the swimmers, creating less hydrodynamic drag for the swimmers.
