What is the rhythm of breaststroke?

1, the swimmer is in gliding posture and his body is close to horizontal. About 80% of the head is submerged in the water, the face is slightly forward, the arms are extended, and the palms are inclined outward.

2. The water receiving action starts from about 7~9 inches underwater, and both hands paddle horizontally. At this time, the exhalation action begins.

3. There is no obvious flexion of the arm, continue to paddle outward, and the exhalation continues to increase.

4. When the swimmer's head starts to lift slightly, the elbow joint starts to flex and the upper arm starts to rotate.

5. When the arms reach the maximum width, the elbow flexion is about 1 10 degrees, and then the elbow posture is obvious.

6. Raise your head. When your mouth comes out of the water, finally exhale. Your hand begins to move inward to complete the final push.

Extended data:

1. When the legs are retracted, the legs naturally droop with the inhalation action, and at the same time, the knees naturally gradually separate and the calves are retracted forward. Relax your feet when you recover, keep your heels close to your hips, and separate them when you recover.

When retracting the leg, the strength should be small, and when retracting the leg and calf, it should be retracted within the projected cross section of the thigh to reduce the resistance when retracting the leg. After the calf is adducted, the thigh and trunk form an angle of about 120- 140 degrees, and the inside of the knee is as wide as the hip joint. The included angle between the thigh and the calf is about 40-45, and the calf should be kept in a vertical posture as far as possible, so as to prepare for kicking.

2. At the end of the leg turn, the foot is still close to the hip. At this time, the knee joint is buckled inside and the feet are everted at the same time, so that the inner sides of the feet and calves are aligned with the kicking direction, which can increase the water surface and make positive preparations for the thighs to exert greater strength. Shrinking legs, turning feet and kicking water are a continuous and complete action process.

The correct turn of the foot begins before the leg is retracted and is completed when kicking the water. If you turn your feet and stop your hind legs a little, it will destroy the consistency of your movements and increase your resistance.
