Water sports
Swimming
Competitive swimming measures speed across freestyle, backstroke, breaststroke, butterfly, and medley events. Efficient body position, propulsion, breathing, starts, and turns determine performance as much as raw strength.
At a glance
- Long-course competition uses a 50 m pool and short-course competition a 25 m pool.
- Stroke rules differ, while pool and timing procedures are shared.
- Modern suits are regulated to limit buoyancy advantages.
Player profile. Swimmers need shoulder mobility, strong core and legs, cardiovascular endurance, breath control, feel for water, and precise repeatable technique. Reducing drag requires a level body line while the arms and legs generate propulsion without disturbing rhythm. Starts and wall turns reward explosive power, but longer events expose inefficient breathing and pacing.
Where it happens
International long-course pool: 50 m by 25 m with ten lanes, of which eight are commonly raced; starting blocks, lane ropes, backstroke flags, and touch timing panels are used. Long-course racing uses 50 m lengths, while short-course turns arrive twice as often in a 25 m pool.

- electronic timing pads
How to play
- Take the legal start for the stroke.
- Swim the full distance within the lane.
- Execute stroke-specific turns and finish contact.
- Fastest legal time wins.
The essential rules
- Freestyle permits any stroke, with front crawl normally fastest.
- Backstroke begins in the water and is swum on the back except during a legal turn.
- Breaststroke arms and legs move symmetrically under its cycle rules.
- Butterfly arms recover together and the legs use a simultaneous dolphin action.
- Medley follows the prescribed stroke order.
- A false start can disqualify the swimmer.
- Swimmers must touch the wall at every turn and at the finish.
- Lane interference is prohibited.
- Relay swimmers may not leave before the incoming teammate touches.
- The whole distance must be completed using legal stroke technique.
How the result is decided
Races are decided by elapsed time; championship placements award medals or team points, and relay time is the sum of each leg. The clock is the direct measure, so a technically legal finish can be decided by hundredths of a second. In a relay, each leg contributes to one continuous team time and takeover timing becomes part of the result.

How the sport developed
Formal racing and standardized strokes developed through nineteenth-century clubs before global federation and Olympic programs expanded the sport. Nineteenth-century clubs helped distinguish and standardize recognizable strokes before international competition joined them in one program. Timed records then made improvements in pools, suits, starts, and turns directly comparable.
- Elite swimmers sometimes remove body hair to reduce perceived drag and improve water feel.
