2. Keep the palm of your hand with the largest water area, and move it downward and backward so that people can float and move forward.
3, when swimming, you should be able to plan water, that is to say, how to plan everything backwards, the thin shape should be slightly bent, and then push back, use the rotation of the shoulders to drive the big arm, then the forearm, and then paddle backwards, to the inside.
4. Breathing is very important for swimmers. Some of them are changed twice, that is to say, they only breathe on one side. When each stroke reaches the bottom, the speed is the fastest. This is a good time for breathing. Finally, after changing the air, the arm should repeat the previous action forward.
Exercise tip: Freestyle technique doesn't have intermittent stages like breaststroke, and you have to turn your head sideways when breathing, so beginners often appear busy and nervous. We should focus on the coordination of movements and pay attention to the relaxation of movements.
Extended data
The basic technical characteristics of freestyle are that the human body is prone in water, with its head and shoulders slightly higher than the water surface. When swimming in, the trunk rolls around the longitudinal axis of the body appropriately, and the two arms take turns paddling to push the body forward. After the hand enters the water, the paddling route is S-shaped, and the breathing and paddling movements are coordinated. When the arm paddles hard, use the water flow to inhale in the valleys formed on both sides of the head.
Freestyle is the fastest swimming posture at present because of its reasonable action structure, labor saving and small resistance. Specifically speaking, in the whole set of freestyle movements, leg movements play a balancing role in addition to propulsion, maintaining the stability of the body and coordinating the arms to do strong paddling. The arm paddling can be divided into front cross, middle cross and back cross.
