First : Ideal backstroke stroke technique

 

Comparing backstroke and freestyle, there are similarities and differences in technique. While comparing backstroke and freestyle techniques, we discuss the ideal backstroke stroke technique.

 

1. Does the arm enter the water parallel to the body's midline?

 

Yes. Backstroke and freestyle are similar in that both are centered on the body's center axis, and the arms are rolled while rolling. The difference is that the athlete cannot see the position of the arm before the end of the backstroke. Therefore, athletes use motion perception to perceive if the arm is outside the centerline, or it is crooked or crossed. The rate of the arm's water entry, holding water, paddling, etc. is related to the position where the arm is moved into the water. The correct arm water entry can reduce the time required for the entire process. During the usual practice, you should always be aware of the existence of the midline, and the arm should enter the water at a position parallel to the midline of the body.

2. Should I push the water fully after the arm is moved?

 

In freestyle, the arm is easily moved by rolling, and the arm can easily rely on the weight of the body. As a result, it can fully push down and stroke the arm. Since the body is lying on the water surface during backstroke, it is difficult for the arm to use the body's own weight. Furthermore, the water must be drawn immediately after entering the water to avoid elbow drag. If the elbow is dragged, the water cannot be effectively pushed. The correct backstroke stroke technique is that after the arm is moved, the arm must fully push down the water, and the opposite arm must also consciously fully push the water down.

 

3. Is the stroke position on the front side of the body?

 

The correct arm stroke position is on the front side of the body, and the hand and arm must be deeper than the water surface. In order to make the hands and arms as deep as possible, it is very important to tilt the body properly. By tilting the body, the hands and arms can be stroked at a deeper position. This is the ideal backstroke stroke technique.

 

4. Is the elbow fully flexed?

 

When the arm is on the front side of the body, when the arm is fully stretched, it cannot form a strong push against the water. The correct technique is to fully flex the elbow while moving the arm while holding the water. The elbow flexion and extension accelerate the water pushing process and make the frequency of strokes faster.

5. Do you push the water below your hips?

 

The movement direction of pushing water is not pushing towards the feet, but pushing towards the bottom of the hips. Due to the rolling of the body, when the arms are straight, they are located just below the hips.

 

Second :End technology

 

One thing that is often overlooked in daily routine training is the "end point technique". The finish technique is the last link of the game. Unlike other swimming techniques, the performance can be shortened by improving this technique. 2--3 seconds this is unrealistic. However, there are many people who regret to lose to their opponents because of poor finishing skills or only 0.1 seconds to fail to meet the standard. On the contrary, there are athletes who use the finishing skills to win. In this sense, it can be said that the "end point technique" is a swimming technique that cannot be ignored.

 

1. Do you realize that the finish timing board is not a "touchpad" but a "pushing board"?

 

The average athlete will call the timing board at the end of the pool a "touchpad" and think that it is enough to touch it. In fact, the end timing board is composed of two layers of inner and outer plates. There is a gap between the outer and inner layers. When the outer layer is under pressure and contacts the inner layer, the electric timer stops counting. There are occasions when the outer panel is lightly touched and the timer is still working. In addition, quick and strong pressing and slow pressing have a certain effect on time, so we must remember.

The end timing board is not a "touchpad" but a "pushing board". Only when this principle is really clear will athletes reduce mistakes in the game

 

2. Does the hand enter the water 10cm before the end timing board?

 

Although it is said to push quickly and forcefully, the finish timing board is harder than the hand. It takes some courage to push it quickly and forcefully. In addition, there is also the possibility of injury. Therefore, it is often fearful The speed of the outrigger becomes slow under the action. In order to solve this problem, it is recommended that the athlete's hand must enter the water at a distance of 10 cm from the end timing board. It feels like a waste of time, but it can eliminate the psychological fear and quickly push the end timing board.

 

3. Do you want to hold your breath at 5 meters from the end timing board?

 

As a practice method, start breathing when 5 meters away from the end timing board, do not breathe until the end of the end timing board is pushed. Athletes are in a very difficult state before reaching the finish line, either in breathing or in a very difficult state. The same conditions should be used during the exercise process. After training, the athlete will adapt to it, even if the body and breathing are in a difficult state, the timing can be just right Push the end timing board.

 

4. Does the body stretch and push the end timing board to the maximum?

 

It's natural to stretch the body and push the end timing board. I have a better understanding of stretching. The end technique of freestyle and backstroke is accomplished by rolling out the arms of the body. Breaststroke and butterfly strokes are achieved by extending the arms into the water at a distance of several centimeters from the end timing board. In addition, you can also slide in a posture with less resistance To the end. This must be fully understood and practiced.

5. Do you want to master your own rate of arm movement?

 

When the end point is about to be reached, whether to use the method of stretching to push the end time plate, or move the arm again to push the end time plate, is to quickly make judgments and decisions. If athletes can understand and master their own arm movement rate and make judgments, the problem becomes very easy. The so-called "arm movement rate" is the time required to move the arm once. There are individual differences in arm movement rate and different swimming strokes. There are also differences. Generally speaking, the self-stroke and butterfly stroke are 1--2s; the backstroke is 1-1.5 s; the breaststroke is 1.5--2. 5s. If the athlete masters his own arm movement rate, he can quickly make a decision by judging the distance and understanding his own arm movement rate before reaching the end point-whether to use the method of stretching or moving the arm again or Allow the paddling arm to return halfway. Therefore, it is very important to grasp the rate of arm movement.
