Due to the influence of paddling and breathing, at the beginning, the hip joint, thigh and knee joint need to sink slightly, and at the same time, the knees should be bent and flexed. At the same time, the knees should be gradually separated and the ankles should be extended. At this time, the calf and heel are behind the thigh, and they are easily retracted in the projection section of the ankle joint, which better reduces the resistance.
In order to save time and speed up the action frequency, high-level athletes will cooperate with the paddling action and try their best to reduce the time of leg retraction.
eversion has a great influence on the breaststroke leg effect. Eversion is not an independent action stage, but needs to be coordinated with the pedal clamp.
At the end of leg retraction, the distance between the feet is wider than the distance between the knees. At this time, you can turn your feet outwards so that your toes are facing outwards, and the knee joint is rotated inwards so that the inside of your feet and calves are aligned with the direction of kicking water.
at the beginning of kicking, the calf should be perpendicular to the water surface, and the foot should be at the best angle (9 degrees) for eversion under the water surface.
The flat breaststroke pedal clamp is characterized by the long pedal path, which can fully mobilize the strength of the medullary joints and thigh muscles.
The leg retraction range of the wave breaststroke thigh is small, but the kick speed is fast, which mainly uses the rotation of the sole of the foot and the cooperation of trunk movements to generate propulsion, and the leg kick will be accompanied by the elevation of medullary joints, which will form the trunk wave movement.
Although the pedaling strength of wave breaststroke is smaller than that of flat breaststroke, it has high frequency, high speed, low resistance and even forward speed, which can make up for its shortcomings.
It is an important stage to generate the driving force and the end of a leg movement cycle.
After the pedal clamp is finished, the legs will slide for a short time due to the inertia of kicking. Before sliding, you should quickly raise your feet to a position parallel to the water surface to reduce the resistance during sliding, and when sliding, your legs should be as straight and close as possible, so that the leg muscles and manic joints will naturally relax and prepare for the next action cycle.

just sleeping on the water and kicking.
It's easy to say. It's very important to test your core. Use your core strength to keep your back floating and make sure that your knees don't come out of the water when you kick.
three kicks.
But this kick should also be played carefully, that is, when you swim deep in the normal breaststroke, kick your legs three times in a row and then paddle for air.
If your triple kick is slow, you will float up, see if you float up, and you will know if you are kicking fast enough. At the same time, you need to use your core strength to maintain your straight position.
It's holding a splayed board in your crotch to breaststroke.
In fact, it is to reduce your kicking range. Think about it. If your legs are open, you can't hold the splashboard.
Of course, when you swim in normally, your legs don't open at all. This exercise is mainly to make your wide kick as narrow as possible.
Straight leg breaststroke refers to kicking with the smallest knee bending angle at the beginning, and then gradually increasing to the state of normal bending breaststroke.
The focus of this training is the bending in the instep direction and heel direction, that is, the degree of bending of your foot surface, so as to make the bottom of your foot feel what the propulsion of breaststroke leg should be.
Every time you kick, the knee bends more than the last time.
until the normal breaststroke kick.
