Swimming is a sport played in swimming pools with normally eight athletes at a time, whose goal is to determine the fastest swimmer among them. Currently 32 evidence are recognized by the International Olympic Committee, being male 16 (13 singles and 3 per team) and 16 women (individual and 13 3 per team).
For the official disputes, the pools can be indoors (gyms) or in open air. The pool measures must be twenty-five meters (Center) or 50 metres long and (Olympic) 20 wide. In Olympic competitions, are allowed only 50 metres pools.
The depth of the pool must be between 1.35 to 1.70 meters, and water temperatures remain strictly between 25° C and 28° c. The pool must contain eight rays, space occupied by athletes in the pool, and 2.5 meters wide each.
From wacostylish, there are five modes in swimming: freestyle (or crawl), back, chest, butterfly and medley. This last is the junction of the four modes in a single test. All styles can be practiced by men and women, individually and by teams only the freestyle and medley are allowed.
In the freestyle, or crawl, the position of the swimmer should be horizontally, with the face facing the bottom of the pool, breathing to turn your head sideways. In breaststroke the position is the same, but the movements of the limbs are circular, and arms move at the same time. The butterfly is a variation of this style, but the movements of the arms are horizontal. In the backstroke, the swimmer must stay with your back towards the bottom of the pool in a horizontal position, being the only style where the race takes place in the water and not the starting block.
1 Among the equipment necessary to get into the pool, the diving goggles, rubber cap for hair (optional if the athlete has a shaved head) and swimwear (Speedo swimsuit for men and for women).
2 Each athlete should stay at your starting block, your corresponding streak, to be given the starting signal.After the starting signal and the jump in the pool, each athlete can be only 15 meters underwater. Case exceeds this limit, will be disqualified.
3 With the exception of the proof of 50 metres, in other evidence (100, 200, 400, 800 and 1500 metres) it is necessary to make the journey there and back in the pool, giving the turn on the edge of the pool at the end of each course. The count of each swimmer is only interrupted when hitting the edge of the pool at the end of the race, officiating the proof for that swimmer.
