Among the four strokes, butterfly may be the most difficult one to learn. Some coaches will say that it is better to master breaststroke and freestyle before learning butterfly, so that butterfly can learn.
However, many people who have mastered breaststroke and freestyle are still confused about the introduction of butterfly. Even if they can swim, the rhythm of butterfly is obviously not right, or the movement is not stretched enough, which leads to the butterfly can not swim for a long distance.
Some people think that learning the butterfly stroke in addition to good-looking does not have much effect, compared with other strokes is not practical, but in fact, the butterfly stroke is the most practical stroke, because swimming itself is a kind of fitness exercise, butterfly stroke is the most energy consuming stroke, so it will have the best fitness effect.
The first word – before
Butterfly is wavy. Many people think that the greater the fluctuation of butterfly, the more obvious the wave making effect. The greater the propulsive force of butterfly, the faster the speed.
This is not right. Although butterfly stroke has ups and downs, it is the result of palm upward or downward extension and head upward or downward. It is not the whole direction of body strength. The whole direction of body strength of butterfly stroke is forward.
The kick of butterfly stroke is to push the body forward, not up and down. A good butterfly stroke is shallow wave making. When swimming in, the body is like floating on the water, rather than flying up and down in the water.
The second word — collar
With the thrust of the butterfly leg, the ups and downs of the butterfly mainly depend on the guidance of the palm and head. It’s very difficult to swim in the floating style at the beginning of learning butterfly, so you can start from the big waves.
It is also because of the big waves of butterfly stroke that it is called “the necessary skills of clearing the pool”. However, it also points out the mistakes of the introduction practice of butterfly stroke. It is not conducive to learn butterfly stroke to be too eager to achieve success and let the arms start to stroke too early.
The two arms are always relaxed and straight forward. When the body plunges deep into the water, the arms tilt down and lower the head, and then the body will naturally and quickly rush into the water with an acute angle. When the palm rises and raises its head, then the body will rush out of the water with an acute angle.
No matter the palm is down or up, it is an acute angle. At the same time, the angle of raising or lowering the head should match with the palm and should not be excessive.
Many people in the butterfly out of the water, the head is not forward to lead, but to lead high, this is wrong, damage the streamline of the body.
The third word — fall
It’s also a difficult point to learn the butterfly stroke, but you don’t need to practice it specially. The beautiful chest pressing movement is produced by the forward movement of the body’s center of gravity and the coordination of the butterfly leg and the waist and abdomen. People who just start to learn don’t have to struggle to do the chest pressing movement.
Although you can’t press your chest, you can lift your chest and wait for your upper body to fall into the water by its natural weight.
When practicing, plunge deeper into the water, and then lead the body up with the head and palm. When you are about to come out of the water, push the two arms back hard, and at the same time, hit the butterfly leg hard to let the upper body out of the water more. The two arms move forward quickly after pushing the water. Under the gravity of the upper body and the two arms, the body falls deeper into the water. At this time, tap the butterfly leg gently, Push your body deeper quickly.
