Therefore, in the breaststroke posture that imitates the swimming action of a frog is often used in competitions. The swimmer's body lies prone on the surface of the water, his arms are bent down on the chest, and his legs are bent down on the side.There are several swimming postures; There are four main swimming postures, which are the fastest swimming postures in freestyle. Common forms of cooperation are 2 strokes per stroke, 6 draws water, and 1 breath.

The butterfly is pushed into the butterfly prone position by alternating shoulder rolling from left and right, and the body swings in a wavy dolphin style.

2. There are a total of 4 swimming postures in swimming competition, including breaststroke freestyle backstroke and butterfly stroke. 1 breaststroke is a swimming posture that imitates the swimming movements of frogs. It is also the oldest swimming posture. The human body is prone on the water, with both arms symmetrically on the chest and straight arms bent down and strokes, and the legs symmetrically flex and stretch to pinch the water. 2 freestyle This posture has reasonable structure, low resistance, uniform and fast speed. It is the most labor-saving swimming posture in the entire freestyle movement; There are mainly the following swimming postures. The breaststroke is a swimming posture that imitates the swimming movements of a frog. When swimming, the body is almost horizontal, and the thighs are pushed backward greatly. At the same time, the arms are drawn outward, and then the arms are drawn inward to the chest and pressed together., and then extended forward freestyle is the fastest swimming posture. When swimming, the body turns sideways, and one arm enters the water and strokes straight along the body to the thigh side; Animal swimming postures are rich and diverse. According to their structure and habits, they can be roughly divided into the following fish. The swinging of the body and fins is the main swimming method. The swinging of the tail fin generates forward thrust. The dorsal fin, pectoral fin and pelvic fin assist in maintaining the balance of the fish. Arthropods rely on the paddling of 5 pairs of plate-shaped swimming feet to swim. In emergencies, they swim quickly by suddenly bouncing their bodies. That is,"bouncing" swimming frogs mainly use "breaststroke" swimming; The breaststroke, also known as the breaststroke, is a swimming posture that imitates frog swimming. It requires the coordination of hands and feet with breathing. The stroke is different from the crawl stroke and backstroke. This posture allows the swimmer to keep his head moving forward. The swimmer can easily observe whether there are obstacles ahead and avoid hitting unknown objects. The breaststroke allows the swimmer to have enough time to adjust his speed, observe the distance, and swim the three-backstroke backstroke at his own pace.

3. Freestyle freestyle has been listed as an official event since the 1st Olympic Games in 1896. It is currently the fastest and most labor-saving swimming posture in the world. Butterfly is named because the swimming movements are like butterflies. When butterfly, the body is prone in the water, relying on the strong stroke of both arms and the wave-shaped kick of the legs to push the body forward. Backstroke without a fixed body posture, including anti-breaststroke and climbing backstroke, is the earliest to appear; Although there are many swimming postures, the following four common postures, each with its own characteristics and different performances. First, freestyle is a posture with high degree of freedom and the fastest speed. The body is prone in the water, almost parallel to the water surface, and the arms take turns to stroke backwards. The legs keep pumping up and down backward and breathing and swimming sideways. The movements of the arms are like crawling.

The swinging of the body and fins is used to achieve advancement. The swinging of the tail fin provides the main thrust. The dorsal fin, pectoral fin and ventral fin help maintain balance. The leaping shrimp is used. Swimming relies on the rowing of 5 pairs of plate-shaped swimming feet. When startled, it can also curl the body to swim and bounce. It is used by adult frogs, and uses hind limbs with webbed between the toes and paddling feet in the water. It is used mainly by paddling birds, mainly relying on webbed between the toes; There are mainly the following swimming postures. Freestyle is the fastest swimming postures, and it is also the earliest posture adopted in competitive swimming. The focus is on grasping the balance and coordination of the body, reasonably controlling the stroke, breathing and leg movements. Backstroke is the only face-up swimming posture. It can effectively reduce water resistance and increase swimming speed. It is also conducive to breathing. The backstroke posture is simple and easy to master. It is suitable for beginners. It is a long-standing breaststroke.

4. There are four swimming postures. They are breaststroke, backstroke, butterfly, freestyle. 1 The breaststroke swimming posture that imitates the swimming action of a frog is also the oldest swimming posture. The human body is prone on the water, with both arms symmetrically on the straight arm side of the chest. Bend downward, and the legs are symmetrically bent and stretched to pinch the water. 2 When swimming in backstroke, the body is lying on the back, and the movements of the arms and legs are irregular. Therefore, the backstroke is often used as an athlete; 2 Butterfly stroke Butterfly stroke is an elegant and strenuous stroke developed from the rules of breaststroke. In butterfly stroke, both arms must swing forward together and feet must be kicked out together. When butterfly stroke, the body lies prone in the water, relying on the strong stroke of the arms and the wave-shaped kick action of the legs to push the body forward. There is no fixed body posture. 3 Freestyle freestyle is one of the most commonly used swimming strokes and the most labor-saving swimming posture in freedom.
