Strictly speaking, freestyle is not a swimming posture, but a competitive swimming event, and its competition rules have almost no restrictions on swimming posture, while freestyle is the most labor-saving and fastest swimming posture, with reasonable structure, small resistance, uniform speed and fast speed. Therefore, in this kind of competition with almost no restrictions on swimming style, people often use freestyle, which has low resistance and fast speed, so freestyle and freestyle are usually regarded as the same swimming style at present.
The basic technical feature of freestyle is that the human body is prone in the water, and the head and shoulders are slightly higher than the water. When swimming in, the trunk rolls around the longitudinal axis of the body properly, and the 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 is paddling hard, use the water flow to inhale in the valley formed on both sides of the head.
Freestyle events account for the largest proportion in the competition, so they become a symbol of strength. Freestyle technology is developing towards practical results, which requires high posture, high elbow acceleration and back stroke, reduced air exchange times, consistent movements and stable and reasonable rhythm. Freestyle technique has no intermittent stage like breaststroke, so beginners often seem busy and nervous because they have to turn their heads sideways when breathing. Pay attention to the coordination of movements and the relaxation of movements.
