Whale swimming goggles, cross practice before swimming

December 16, 2021

Practicing swimming is the entry and catching stage of the arm stroke. Put your arms straight, place your hands above your head, palms down towards the bottom of the pool, separate your hands with the same width as your head, and use one arm to hold the water. The water posture fixes the palm to the effective position of pushing the water forward, pulls the water forcefully, while keeping the fingertips towards the bottom of the pool, slide the palm along the shoulder and hip line, the palm of the hand comes out of the water when passing the buttocks, raise the elbow and move the arm, Relax hands and forearms;

Before re-entering the water, turn the palm into a stroke position, still keeping a head-width distance from the other hand. Repeat the stroke method, with one hand in front and the other hand immediately forward, with your hands crossed.

Side kick exercises. In freestyle, due to the rotation of the body in the water, we actually spend more time on both sides of the body than in front of the body. So side kick exercises are very important for swimmers to enhance coordination and balance. Lie on your side in the water, with one arm stretched forward and the other arm on your side, kicking across the pool. After reaching one end of the pool, change the direction of lying on your side. Continue to practice near the lane line to help you grasp the direction. The straighter the route in the water, the more efficient your swimming.

When entering the water, when the arm enters the water, the fingers are naturally close together and straight, the palm is facing outward and downward, and the elbow joint is slightly bent and higher than the hand. Leading by the thumb, insert the water obliquely. The order in which the entire arm enters the water should be hand, forearm, upper arm. The entry point is on the extension line of the shoulder or between the midline of the body and the extension line of the shoulder. It is not good for the entry point to be too wide or too narrow. Too wide is not conducive to holding water, and too narrow will destroy the streamline of the body. The action of entering the water does not produce propulsive force. The action should be smooth and minimize the resistance.

Hold the water, extend your arm forward and downward along the water surface for 20 to 30 cm after entering the water, so that the arm is nearly completely straight, and then the upper arm is kept still, the forearm is slightly externally rotated, and the palm is turned from outward and downward to directly downward, and then bend Gradually bend the wrist and the elbow so that the elbow is higher than the hand and move inward and upward until the upper arm is at an angle of about 30° with the horizontal plane, the forearm is at an angle of about 60° with the horizontal plane, and the elbow joint is bent at an angle of about 150°.

Paddling. Paddling is the main stage to gain propulsion. The water is divided into two parts with the shoulder as the boundary. The paddling in front of the shoulder is called "pull", and the paddling behind the shoulder is called "pushing". When pulling water, the degree of bending of the elbow joint gradually increases, and the arm maintains a high elbow posture, accelerating the stroke in the backward, inward and upward directions. When the arm is drawn below the shoulder, the hand is close to the midline of the body under the body, the arm is perpendicular to the horizontal plane, the palm is backward, the elbow is outward, and the elbow is bent to 90° to 120°. Push the water stage. When pushing the water, try to make the forearm and hand align with the water with the largest area. While pushing the water in the direction of backward, upward and outward movement, gradually extend the elbow and wrist while pushing the arm back to the thigh. , When it is at an angle of about 20° with the horizontal plane, the water push ends.
