Finswimming is an underwater swimming sport where athletes race against each other with the use of floating and breathing equipment like masks, fins, snorkels and a scuba diving set.
Finswimming competitions are conducted in both swimming pools and open waters. Competitions in swimming pools feature short-distance races, while long-distance races are conducted in open waters.
Four techniques are used for finswimming, and races are conducted separately for all techniques. The techniques are:
- Surface swimming: Swimmers use a mask, snorkel and monofins, and must always remain at the surface of the water. Individual races for 50, 100, 200, 400, 800, 1500 meters and relay races for 4 × 100 and 4 × 200 meter are held for his technique.
- Bi-fins swimming: Swimmers use a mask, snorkel and a pair of fins, and swim at the surface of the water. Races for 50, 100, and 200 meters are conducted in a swimming pool, and long-distance races of 4km or 6km are conducted in open waters.
- Apnoea finswimming: Swimmers use a mask and monofin and swim underwater holding their breath. Only 50m races are conducted for this technique. All races are conducted only in a swimming pool.
- Immersion swimming: Swimmers use a mask and monofin and swim underwater using breathing apparatus. Races are conducted for 100m and 400m using this technique, only in a swimming pool.
