Some things about the swimming competition
What is streamlining?
Streamlining is a swimming technique that is used underwater every time you stroke. The streamline technique is used at the beginning of a race or turn and is usually used in conjunction with a dolphin kick or chatter kick, which creates minimal resistance and helps the swimmer to advance as fast as possible.
Most commonly swimmers dive head down into the water with their arms raised above their head and enter the water in a streamlined pattern so they look like a fish. The other common streamlined shape occurs after the swimmer finishes flipping and pushing off the wall. The streamlined position is a stroke with the spine as the axis, and the backstroke and freestyle are based on the streamlined position. Swimmers will work to keep their backs and legs straight to reduce "drag".
How do you perfect your swimming streamline?
The fastest an athlete can move through the water is when they dive into the water and off the wall. A smoother streamline allows them to use less time to slide farther and faster. So streamline the flow.
If limited flexibility gets in the way of your streamline, the best thing to do is to perform stretches on land to increase shoulder flexibility. This will also help keep your shoulders and back healthy. If core strength is limited and it is difficult to maintain a good body line, then try yoga training. These two water programs will not only improve your flow, but also your stroke. Of course, these should be done in the company or under the supervision of a professional.
Some rules for swimming competitions
Start
The referee first signals the participating swimmers with a few short whistles, which means that the race is about to begin and the swimmers are to take off all their clothes except their swimsuits. The head judge then blows the whistle and orders the swimmers to take their positions. They can be on the starting platform, on the deck or on the water, depending on the stroke of the race.
Once all swimmers are ready, the referee extends his hand to the starter. With all swimmers in their starting positions, the starter will signal and the race will begin. If a swimmer is not immediately scored, the starter will order the swimmer to "stand up". Swimmers can move from their starting position until they are told again to keep score. Once all swimmers are in the starting position, the starter will signal the start of the race. If a swimmer does not mark immediately, the starter will order the swimmer to "stand up". Swimmers may move out of their starting position until they are told to mark again.
In swimming, there is no "false start" warning signal. Any athlete who jumps into the pool before the signal is given will be automatically disqualified from the race. However, if the signal is given before the disqualification is announced, the race may continue and the swimmer will be disqualified at the end of the race.
Turns
In swimming competitions, you will see athletes approaching the wall with a turn and stomp, what does this do? This is very common in competitions because a normal turn in the water like on land will create a lot of "drag" and will be very slow, so there is a turn to stomp the wall, which is also called a fast turn. Fast turns are critical to a great race. In any case, the swimmer must make contact with the wall when turning.
In freestyle and backstroke, the swimmer may somersault and stomp the wall as he or she reaches it, touching it with only his or her feet. In butterfly and breaststroke, swimmers must touch the wall with both hands at the same time before turning.
There are also different rules and requirements like breaststroke, backstroke, butterfly, freestyle, and medley, so I won't go into details here.
