Location
A swimming test must be played in a swimming pool, which can be located in a gym closed or open. The pool should be 50 m (measured Olympic) or 25 m (measured semi-Olympic) long and 25 m wide, with depths around 1.8 m. The water temperature must be between 25 º C and 28 º C.
The space that each player holds in the pool is called a streak. Any swimming competition must have eight lanes of 2.5 m wide each. Except in the style back, the swimmers range of a starting point, which lies along one edge. This base, in fact, is a square block of cement, coated with anti-slip material, which is between 50 cm and 75 cm above the water. This is a cube with 50 cm side, where there is also a medium (bar) used for starting the backstroke, which should be between 30 cm and 60 cm from the surface of the water. Currently the blocks of matches are made of a material inclined, which allows 90 ° angle of the leg and increases the urge to start.
The arrival of 5 m (1.8 m above the water) is a line of flags, which helps the swimmer’s style back to view the proximity of the end of the race. There is also a false start rope, which is 15 m from the edge of the pool (above the water surface) and falls into the pool when a swimmer dives before the starting line.
