1. Which of several common swimming positions is the fastest?
The speed is: freestyle, butterfly, backstroke, breaststroke, men 100 m, respectively: freestyle 47 "84, butterfly 50" 76, backstroke 53 "60, breaststroke 59" 94. So freestyle is the fastest. The reason is that freestyle can take any position in freestyle events (because freestyle is the fastest, athletes often freestyle in freestyle events). Freestyle means that the body is prone in the water, almost parallel to the water surface, paddling backwards by two arms in turn, pumping water from the legs up and down to the rear, and swimming in sideways. Because the arms move like crawling, it is also commonly known as crawling.
This position is the fastest swimming position because of its minimum head-on lift, good paddling effect, free movement coordination, labor saving and fastest speed.
Second, how to learn freestyle quickly
There are many forms of perfect cooperation in freestyle. Generally speaking, it is common to draw water twice, draw water six times and breathe 1 time.
1, the entry point of the hand is between the extension line of the shoulder and the midline of the body, and the thumb is used as the faucet to enter the water obliquely.
2. After entering the water, the hands, elbows and shoulders continue to stretch forward to stretch the arms. Bend your wrists, elbows and arms as your body rotates.
Grab water outside and behind; After the hand stroke reaches the lowest point, rotate the arm to stroke inward, upward and backward, and keep the stroke posture of high elbow and bent arm.
3. When the arm is perpendicular to the horizontal plane, take the lead in accelerating the pedal, turn the arm outward, upward and backward until the thigh side, and lift the elbow out of the water.
4. After the water comes out, the arm moves forward naturally and relaxed through the air, keeping the elbow posture high. Then put your hand on your shoulder, lead into the water and start the next action.
Third, how do freestyle legs kick water?
1. Kicking starts from the hip, and the thigh drives the calf to do whipping.
2. Kick up from the corner. Start with straight legs, bend your knees when your feet are close to the water, lift your calves up so that your feet can get out of the water, and then draw water down. At first, you can draw water with straight legs, but your legs are slightly relaxed and don't be stiff. Under the pressure of water, your legs will
Natural bending. The knee flexion angle is about 65,438+0.30-65, 438+0.60 degrees and the stroke width is about 30-40 cm. Stretch your feet when you draw water (similar to ballet feet in ballet), and don't hook your feet.
