Competitive swimming became popular in the 19th century. The goal of high level competitive swimming is to break personal or world records while beating competitors in any given event. Swimming in competition should create the least resistance in order to obtain maximum speed. However, some professional swimmers who do not hold a national or world ranking are considered the best in regard to their technical skills. Typically, an athlete goes through a cycle of training in which the body is overloaded with work in the beginning and middle segments of the cycle, and then the workload is decreased in the final stage as the swimmer approaches competition.
The practice of reducing exercise in the days just before an important competition is called tapering. Tapering is used to give the swimmer's body some rest without stopping exercise completely. A final stage is often referred to as "shave and taper": the swimmer shaves off all exposed hair for the sake of reducing drag and having a sleeker and more hydrodynamic feel in the water.[11] Additionally, the "shave and taper" method refers to the removal of the top layer of "dead skin", which exposes the newer and richer skin underneath. This also helps to "shave" off mere milliseconds on your time.[12] World record holder and Olympic gold medalist Michael Phelps in the 400 IM.
Swimming is an event at the Summer Olympic Games, where male and female athletes compete in 16 of the recognized events each. Olympic events are held in a 50-meter pool, called a long course pool.
There are forty officially recognized individual swimming events in the pool; however the International Olympic Committee only recognizes 32 of them. The international governing body for competitive swimming is World Aquatics, previously named the Fédération Internationale de Natation ("International Swimming Federation"), or more commonly, FINA, prior to 2023.[10] Open water In open water swimming, where the events are swum in a body of open water (lake or sea), there are also 5 km, 10 km and 25 km events for men and women. However, only the 10 km event is included in the Olympic schedule, again for both men and women. Open-water competitions are typically separate to other swimming competitions with the exception of the World Championships and the Olympics.
