What is the difference between wave breaststroke and basic breaststroke?

1. The difference in body posture.

Flat breaststroke body posture characteristics: In each movement cycle, the body posture of the flat breaststroke is relatively close to the horizontal position.

Body posture characteristics of the wave breaststroke: The essence of the wave breaststroke is "chasing the waves". The shoulders are exposed to the water, the hip joint is relatively low, and the body forms an angle to the horizontal plane.

2. The difference in leg tightening amplitude.

The thighs are closed at a 120 140° angle to the torso at the end of the flat breaststroke, and the knees are about the same width as the hips. The thigh is at an angle of 40 45 ° between the calf.

Unlike the wave breaststroke, the thighs are retracted in a small way because the shoulders and back are raised above the water, the hips and legs are sinking, and the calves and feet are not exposed to the water.

3. The difference between pedaling and pinching water.

In the flat breaststroke, in order to obtain a larger water pushing area, the calf and foot are rotated inward, located on the outside of the thigh, and the oak thigh is driven to push the calf backward by the internal rotation of the thigh and the hip extension.

Push outwards and backwards until the knees of both legs are close to extended. After that, the calves and soles of the feet continue to push down and back, and the legs are pinched in the middle while pushing backwards.

The amplitude of the thighs in the wave breaststroke is not large, and the water pedaling process is spiral-shaped, and the speed is very fast, mainly using the rotation of the soles of the feet to generate propulsion.

4. The difference between breathing.

The inhalation of the flat breaststroke is done with the help of a head up. For the wavy frog such as Spike Swimming, the head and shoulders are no longer just about inhaling, but an important part of forming the wave action.

5. The difference between complete coordination actions.

The breaststroke arm and leg are more complicated with the skill friend's tanshu. The common flat breaststroke technique is to naturally relax and straighten the legs when paddling outward, sink the legs and bend the knees when paddling inward, and stretch the arms forward to 2 3 o'clock to quickly push the clip.

Unlike the "stroke and kick" rhythm of the flat breaststroke, the rhythm of the wave breaststroke is "stroke forward and kick".

The forward thrust is a unique feature of the wave breaststroke. It occurs between the end of the inward stroke and the beginning of the pedal, when the hands and forearms are just at level and parallel to the surface of the water. Strokes and arms extension begin with a back-arch of the chest and back, and arch the back upwards when lunging forward.

Hungarian Nagy is the inventor of the wave-style breaststroke. He believes that in the wave breaststroke technique, the trajectory of the shoulder movement is a symmetrical wavy shape. That is, the ups and downs of the waves are symmetrical and do not fall abruptly after breathing.

The movement of the legs is also crucial, and the body must be forward at the right time to complete an action called "mop".

1. Pay attention to shoulder lift skills

In the breaststroke technique, the breaststroke is performed at a deeper depth of the water and has a lot of resistance. But the wave breaststroke is different, it moves subtly below the surface. The back collapsed with the right amount of force, and the upper body was lifted out of the water, leaving only the waist and legs in the water.

This greatly reduces the resistance. As the arms begin to stretch forward, the back changes from a concave to an arch. If done right, it can generate more thrust.

This change in back posture is very important. When the back is concave, the quick and powerful movements of the hands will raise the head and torso above the water; The upper arch of the back works with the kicking leg to push the hands and body forward. Abenshik added:

Because there is a lower dent in the back, raise your body high enough to jump forward and start kicking.

Second, pay attention to the center of gravity skills

Swimmers who are able to jump forward with wave-style breaststroke keep their center of gravity about four to five inches underwater without going up and down. Balamane and Nigi had the same opinion. In his correspondence with the author, he said that it was crucial that the buttocks hardly rise or fall during the entire cycle of movements.

Of course, there are ups and downs, but that's the difference between being fifth and being number one. If the hips move up and down, the center of gravity will shift, thus wasting physical strength. This is the biggest difference between Barman and Rosa's skills.

Finally, the significant difference between the wave breaststroke and the traditional breaststroke is that the head and upper body are out of the water as the body continues to slide forward. The widest part of the body, the shoulders, can raise the water. In addition, the shoulders are almost arched to the ears, which helps to keep the body more streamlined.

In breaststroke, it is known to move the arm in the water, which is done at a deeper depth, thus creating a lot of resistance from the surrounding water. But the wave-style breaststroke is different, and its ingenuity lies in the action below the surface of the water. The beginning of the stroke and arm transfer is concave dorsally; The back arches upwards when rushing forward.

Also, the timing of the leg press is key. The second is to breathe, the difference between the two swimming styles is that one morning and one night, the flat frog is the outer stroke begins to raise its head synchronously for ventilation, and the breathing mode used by the wave frog is late breathing, you can try to stroke the head outside and do not move, and then start to look up for ventilation.

The first technique is to lift your shoulders so that your body is concave, the second technique is to swim with a stable center of gravity, and the third technique is to push your legs straight back.

The breaststroke in this posture is first of all to fully use your arms when you are in the water, and then you must not force the stroke, but slide along the current to be able to swim.

Now the definition of a wave frog and a flat frog is distinguished by the trajectory of the body: the flat frog body advances in a horizontal shape, and the wave frog body moves in a wave shape. The wave frog should at least have to come out of the water on the shoulder, while the flat frog only has its head out of the water, and relatively speaking, the tall frog can also be called the wave frog.

There are many schools of breaststroke technology, even if the high frog is subdivided, there are different names, it is not necessary to divide it so finely if it is not a professional teaching, and it is not easy to be "confused" for the majority of amateurs. As for distinguishing from the movements, it is wide, and each part is different, which is not something that can be clearly explained in one or two sentences. In the breaststroke, a stroke, a breath, a leg kick under the large frame of the flat frog movement rhythm is:

Paddling and kicking the legs, the rhythm of the movement of the wave frog is: paddling and punching the legs. The forward pounce is unique to the wave frog, which starts to kick the water when the forward pounce is three-quarters complete, and the last quarter completes the entire forward pounce by kicking the legs.

If the flat frog is not proficient, it is not recommended to know too much, and you should not blindly start learning the wave frog, otherwise it is easy to make the first floor friend dizzy. If the foundation of the frog is good, the frog will learn quickly, and it is easy to compare and solve all kinds of problems encountered in learning.

Wave frog learns quickly@ encounters all kinds of questions in learning, and it is easy to compare and solve them.
