During breaststroke, the body is lying prone horizontally on the surface of the water, with both arms straight forward and close together. The head is slightly lowered, the water is on the forehead, and the lower part of the face is immersed in the water. Slightly tuck the abdomen, slightly collapse the waist, the longitudinal axis of the body is about 5゜~10゜ in the forward direction, keeping the body streamlined.
Leg movement during breaststroke;
Leg movement is the main driving force that pushes the body forward. It can be divided into four inseparable action stages: sliding, retracting the legs, turning the feet and kicking the water.
1. Retracting the legs: Retracting the legs is the beginning of sliding. The legs begin to sink due to their own weight. At this time, the legs are slightly internally rotated to separate the heels, and the calves and feet are as close to the hips as possible. The knee joints are retracted forward with the sinking of the legs. Side points. When the legs are closed, the distance between the thigh and the torso is 130゜~140゜. It is required that the retraction route be short, the resistance should be small, and it is necessary to create favorable conditions for kicking the water.
2. Turning the foot, turning the foot is the continuation of the leg retracting. The kicking starts. With the end of the leg retracting, the feet continue to tighten toward the hips. While the thighs rotate inward to press the knees, the calves turn outwards, and the toes are also facing at the same time. Turn both sides outward so that the inside of the sole of the foot is facing the direction of the kick.
3. Water kicking: Water kicking is the force exerted by the hips after turning the foot, which drives the knees and ankles to straighten one after another, and makes rapid and powerful kicking movements with the thighs, inner calves and inner soles of the feet. In the process of kicking and clamping, when the legs are gradually brought together, press down slightly to form the final whiplash action.
4. Glide: After kicking the water, the body slides forward with the help of inertial force. The two legs, including the toes, are brought together and straightened back. The gluteal muscles, thigh quadriceps and gastrocnemius muscles are slightly tense, and the body is in a horizontal position to prepare for the legs to be retracted.
Three breaststroke hip movements;
Breaststroke hip movements can be divided into four inseparable stages of action, namely, catching, paddling, closing hands and extending buttocks.
1. Catch the water: slide closely, keep your shoulders extended, rotate your arms inward, turn your arms and palms to the lower side and bend your wrists, and then separate your hands to press the water towards the lower side of the side. When the palms and forearms feel pressure, start paddling.
2. Paddling: Immediately after catching the water, start speeding up the paddling. The direction of the paddling is to the side, down, back, and inward. The elbows are kept high during the stroke, and the flexion angles of the forearms and upper arms are constantly changing throughout the stroke. The elbow flexion in the main stage of the stroke is close to 90 ゜.
3. Retracting: Retracting is the continuation of the stroke, which can generate ascent and forward force. With both arms retracted inward and upward to reach the lower and front of the lower jaw, the palms turned from back to inward. The elbow is lower than the hand, and the upper arm does not exceed the extension line of the shoulders. Try to put the arm in the projection of the body, so that it can play the propulsion inertia caused by the stroke, and reduce the resistance of the water to the arm extension.
4. Extend your arm: Hold your hand tightly and continue to push your elbow to extend your arm. Turn your palms down, relax your arms, stretch your shoulders and then your elbows, move your arms up and then forward, keep your body in a streamlined shape, and return to the sliding position at the end of your arms extension.
Cooperate technique when breaststroke with four arms, legs and breath;
The overall action of the breaststroke
Breaststroke breathing and arm strokes are closely coordinated, and generally take one breath in a cycle of movement. Breathing methods are divided into "early breathing" and "late breathing". "Early breathing" means raising the head to inhale when the arms start to stroke, and then lowering the head to exhale when the arms are stroked. "Late breath" is when you start to raise your head when the stroke is almost finished, draw your arms to your chest and inhale when your body reaches the highest point, then lower your head and hold your breath as you stretch your arms, and gradually exhale when your arms begin to stroke outward. It is more advantageous for beginners to use "early breathing", because there is a larger supporting surface when the arms are stroked so that the head is exposed to the water for inhalation.
The complete coordination of hips, legs, and breathing can be done by stretching the arms forward and the legs straight and sliding together after the kick, and then start the arm grabbing action, and then raise your head to inhale. When you close your hands, close your legs and make a kick while extending your arms.
