Teach you how to swim rhythmically

Coaches often say this, please pay attention to the rhythm, please maintain the rhythm, please swim the rhythm ... Swimming rhythm is really important, master the swimming rhythm, you can swim far and fast! A good rhythm can not only ensure effective and efficient action, but also assess whether the technical action is reasonable, and it is a prerequisite for mastering the correct technology and achieving excellent results.


In swimming sports, although the four postures of butterfly, back, frog, and self are complicated and have different structures, they collectively show the time and space relationship between the amount of force and a certain action. That is, during the full practice, the relationship between the strength of the technique, the duration of the exertion and the interval and the magnitude of the action are shown between the various links of the technology and the various links of the action. We usually call it the rhythm of technical action. Rhythm is very important for swimming. The technical movements of various swimming postures have their own movement rhythms. In any case (such as slow swimming or fast swimming), the proportion of their internal speed should be maintained relative Stability must not be inverted.


First, the expression of rhythm

Rhythm is a comprehensive expression of technical movements and physical exercises, and its expressions are various.

1. Sequence of actions


In swimming, regardless of the posture, the cooperation of the arms, legs, and heads is performed in succession and simultaneously, and each of them forms a certain speed proportional relationship at a certain time interval and strength relationship. . Reflects when, where, and how forces work. Such as the butterfly stroke (1: 2), its rhythm characteristics are kicking, pushing water, raising head for ventilation, lowering the head, pressing water into the shoulders, kicking and raising the hips.


2.Amplitude change of action


In the swimming movement, the four postures jointly implement a criterion, that is, the action section (amplitude) acting on water should be large and fast, and the action section (amplitude) not acting on water should be small and slow. Such as breaststroke leg movements, the rhythm characteristic is that the amplitude of the legs should be small, and the two legs should be hidden behind the thighs (to reduce the cross section of the water) and slow to retract (the effect of reducing the reaction force). Two feet and two calves should be divided inside and outside (increasing the cross-section of the water) and quick pedal clips (increasing the force).

3. Strength and strength of muscle force


In the four swimming positions, although the movements are quite different, the strength and strength of the muscles show strong rhythmic characteristics and consistency. For example, the muscles of the arm are strong and strong during the stroke and water-pushing phases, and the muscles are weak and weak during the water-entry and water-holding phases of the arm. The same is true for leg movements. Muscles are strong and strong when kicking or kicking, and muscles are small and weak when lifting or pressing down.


4.Tenseness and relaxation of movement


The tension and relaxation of movements is another distinctive rhythmic feature in swimming. It is mainly reflected in the ability to gain momentum. In the power phase, the arms are held, paddled, pushed, and the legs are kicked or kicked tightly. In the non-powered phase, the transfer of the arms and the lifting or pressing of the legs are relaxed. For example, in the freestyle arm movements, from the beginning of the hand holding the water to the end of the push, the entire arm movements are tense, and the entire arm movements during the lifting and entering phases should be relatively relaxed.

Second, rhythm and technical action

From the superficial nature of the rhythm, it can be seen that the speed, amplitude, strength of the action, the length of time, the tension of the muscles and the relaxation of the time interval are the basic conditions for the formation of the rhythm. Not only does it exist in any movement and practice, but it is also the most important and essential relationship and feature of sports technology. Therefore, in swimming teaching and training, mastering a reasonable rhythm is conducive to mastering technical movements and helping to form the correct dynamics. If you do not master a reasonable rhythm, the coordination of movements will become uncoordinated and appear stiff. Can't save, work efficiently and lastingly, thus reducing the effect of action.

Three points should be paid attention to rhythm training


1. Pay attention to establishing an accelerated rhythm


Accelerated rhythm is a very important basic feature in swimming sports technical movements. The key to complete technology is to be able to master the accelerating rhythm of technology and make the rhythm stand out fast. Therefore, in teaching and training, according to the characteristics of the rhythm of swimming technique movements, a dynamic pattern of the acceleration and hard rhythm of the arm stroke, water pushing phase, and foot, leg hitting, and pedaling phase should be established.

2. Pay attention to building a comprehensive feeling


In swimming teaching and training, the complete technique must pay attention to the movement trajectory, the timing of the force, the strength of each part of the body, the speed and amplitude of the force; pay attention to the consistency of the action and the correct connection method, and the cooperation and The relationship is to experience the rhythm in the mastery. At the same time, with the help of vision, skin pressure and various visceral sensations and muscle sensations, a "rhythmic sensation" is established to form a "comprehensive sensation" integrated with strength and time, so as to form the correct action rhythm.


3. Pay attention to the usual repeated requirements


Good movement rhythm can only be formed after long-term training. Therefore, in the practice process, it is necessary to consciously strengthen the repeated requirements for technical rhythm or carry out targeted exercises. It is necessary to clearly emphasize which parts of the action range should be large, which parts of the range of action should be small; which parts of the action force should be large, and which part of the action force should be small; which muscles should be tense, which muscles should be relaxed and which parts of the movement require special attention, Which parts are secondary.

All in all, any technical action requires a good rhythm. Only when special attention is paid to the cultivation of a sense of rhythm in teaching and training can it be possible to make the technical action more complete.
