First, the purpose of kicking
Everything is regular, including the learning and training direction of freestyle: the research direction of modern swimming technology is 1, increasing strength, 2, reducing resistance. Relationship between water resistance and speed: Water resistance is directly proportional to the square of speed. In other words, if the speed increases by 2 times, the resistance will increase by 4 times. If the speed is tripled, the resistance will increase by nine times, and so on.
After understanding the relationship between motivation and resistance, you should understand-if you want to swim quickly and easily, strengthen your core strength! But the wise man found that the improvement of human strength is limited! Reducing resistance is more important!
The main purpose of kicking is the same-keep your body in the water, keep it streamlined-reduce resistance-which is the most important. The second is to provide power.
Kicking and kicking must be in a straight line, and the rotation of the body must be in a straight line. Always stay within the vortex range generated by the upper body. The depth and width of kicking water are limited.
This is the requirement of kicking water technology-starting from the hips, driving the knees and ankles to kick water continuously in a streamlined way, and keeping the body in an excellent streamlined state. The waist and hips as a whole kick to drive the body to rotate rhythmically.
The strength of the waist and buttocks controls the kicking of the legs, so that the body rotates to reduce the resistance and the body gets exercise. This is the purpose of kicking water technology!
2. Kicking technique is the foundation of freestyle.
Why do you have to practice kicking in freestyle swimming? Because the training premise of practicing some basic skills of freestyle is to have good kicking skills-for example, the most important basic skills of freestyle training-posture, balance and streamline all need good kicking skills to cooperate! The quality of kicking technique determines the streamline of the body, the streamline determines the balance, and the control of streamline and balance determines the quality of rotating technique!
The following related videos and explanations illustrate this point well!
Third, when swimming freestyle, you must practice kicking.
Swimming is a physical exercise, which needs to be based on the technical characteristics of freestyle and the technical purpose of swimming-reducing resistance and exerting the overall strength of the body on the premise of reducing resistance!
If you can't control your legs, you can't control your body Legs are an important part of your body. Therefore, if you want to swim freestyle well, you must practice kicking well!
To sum up: kicking is for efficiency, not for speed.
The key is to make your legs move in the most natural and efficient way and avoid unnecessary movements. An effective and accurate water rhythm can make the whole movement of the power chain more powerful and only need a little energy.
For a truly balanced swimmer, this will definitely not happen, because a balanced swimmer can get water and move freely. When they draw water, they will find the best exercise mode to coordinate their body movements best.
Add a toe that is precisely synchronized to your body rotation. When you add the right and moderate strength at the right time, you can feel your hips get a greater push. If you imagine that you can connect upper limb stroke with body rotation, this increased hip thrust will eventually translate into more powerful stroke.
Key words: the quality of kicking technology determines the control of body streamlining and balance technology-that is, drag reduction quality!
The control quality of body streamline and balance technology determines the fluency of rotation, that is, strength quality!
Fourth, how to practice kicking?
The first step: the undergraduate support board is immersed in kicking and experiencing waist and hip whipping!
It is required to practice the project every time! The purpose of this decomposition exercise is to master the basic body streamline, water balance and continuous kicking ability.
Step 2: Advanced hands reach forward and kick the water to control the streamline of the body and balance in the water!
This decomposition exercise is mainly to practice continuous kick rotation and streamline the body.
The third part: one of the advanced hands stretches forward and kicks to realize the body rotation!
This decomposition exercise is very important, mainly the initial experience of practicing kicking and turning, streamlining the body and strength chain.
Step 4: Advanced single-arm paddling and breathing on different sides to achieve smooth power chain!
This decomposition exercise focuses on the rotational balance of the body! Let your body go swimming! There is also the practice of power chain!
After reading the comments on the above video, I believe you have a comprehensive and in-depth understanding of the kicking technique, but I still summarize it to deepen your memory.
1, the strength of the waist and buttocks controls the kicking of the legs, so that the body rotates to reduce resistance and the body gets exercise. This is the purpose of kicking water technology!
2. The quality of kicking technique determines the quality of keeping the body streamlined. The quality of balance control depends on the quality of streamline and balance control, while the quality of rotation technology depends on streamline and balance control!
3. The control quality of body streamline and balance technology (i.e. drag reduction quality) determines the smoothness of rotation, i.e. stress quality!
