The most common purpose for swimming is recreation. Recreational swimming is a good way to relax, while enjoying a full-body workout.
Several swimming styles are suitable for recreational swimming; most recreational swimmers prefer a style that keeps their head out of the water and has an underwater arm recovery. Breaststroke, side stroke, head up front crawl and dog paddle are the most common strokes utilized in recreational swimming, but the out-of-water arm recovery of freestyle or butterfly gives rise to better exploitation of the difference in resistance between air and water.
The goal of competitive swimming is to be the fastest over a given distance. Competitive swimming became popular in the nineteenth century, and comprises 36 individual events ? 18 male events and 18 female events, however the IOC only recognizes 34 events ? 17 male and 17 female events. Swimming is an event at the Summer Olympic Games, where male and female athletes compete in 13 of the recognized events each. Olympic events are held in a 50 meter pool. Competitive swimming's international governing body is FINA (F?d?ration Internationale de Natation), the International Swimming Federation.
Diving refers to the sport of performing acrobatics while jumping or falling into water from a platform or springboard of a certain height. Diving is an internationally-recognized sport that is part of the Olympic Games. In addition, unstructured and non-competitive diving is a common recreational pastime in places where swimming is popular.
Most diving competitions consist of three disciplines: 1m and 3m springboards, and the platform. Competitive athletes are divided by gender, and often by age groups as well. In platform events, competitors are allowed to perform their dives on either the five, seven and a half (generally just called seven) or ten meter towers. In major diving meets, including the Olympic Games and the World Championships, platform diving is from the 10 meter height.
