Regular swimming can make your body slimmer and more well-proportioned, so many people like to swim in their spare time. People who have just learned to swim, and can only do the doggy paddling in the water, will often be very envious of others who can do the butterfly stroke, breaststroke, backstroke, freestyle, etc., with graceful postures, just like a mermaid swimming freely in the water. In response to this situation, the editor shares with you the key points of various swimming movements. Today, I will share the key points of backstroke: Backstroke action essentials quick learning To learn backstroke well, you must fully master the movements and techniques of backstroke. Once you have mastered these, how to learn backstroke is no longer a problem. In the process of learning backstroke, you should pay attention to the backstroke head technique, backstroke leg movements, backstroke arm movements and backstroke waist posture. Head skills: In backstroke technique, the head plays the role of a "rudder" and can control the left and right rotation of the body. The head should remain relatively stable and not shake up and down or left and right, but the neck muscles should not be overly tense. The back of the head should be in the water, the water level should be near the ears, and the eyes should look above the legs. Waist posture: When swimming backstroke, the waist muscles should maintain moderate tension to prevent the body from being too straight and the hips from being bent into a sitting or lying position. Lift your ribs and don't hunch your chest. When swimming quickly, the body's angle of attack can raise the body position. Athletes with higher levels not only have their shoulders and chests above water, but their abdomens are often also above water. Backstroke leg techniques: When the leg movement ends, due to the resistance of the water on the calf and the restraint of the thigh muscles, the thigh and calf form an angle of about 135-140 degrees, and the calf forms an angle of about 40-45 degrees with the horizontal plane. No matter which type of swimming you choose, you must do warm-up exercises before entering the water to avoid accidents in the water. If a person has an accident in the water, his life may be in danger. Also, don't swim for too long. You should stay in the water for a maximum of two hours. If you stay in the water for too long, it will be harmful to your body. |
