The principle of movement is "support"! Without support, there is no advance. For the three sports of swimming, cycling and running, the main purpose is to move the body.
The principle of moving in the water is the same. If the supporting point of the palm is firm enough during the process of catching, holding, and pushing the water, the palm does not actually move. The only thing that advances is the body. The palm moves forward only after lifting the arm.
It's easy for us to fall into the myth of "stripping the water backwards and the body can move forward", but that's like running on a treadmill, your feet and tracks are constantly sliding backwards, but your body stays in the same position.
So if we just want to move forward by "swinging arms" in the water, we will forget that what we really want to move is the body, not the arm. Imagine: If you just move your arm repeatedly, but your body does not move, it is like lying on the shore and "stripping". The body becomes a solid immobile support point (immobile support part), but the arm becomes constant. Swipe back and forth (moving part).
It will become just a stroke of water, not a stroke of the body. What we really want to move is the body, not the palm. Only when the palm forms a solid support point (the immobile support part) can the body move smoothly (moving part).
Imagine how to climb a wall. First of all, you raise your hands with your palms to buckle it, assuming that your arms are strong enough to jump up and then up, your body can move up smoothly. It's just your body that moves, the palm doesn't move, it's still on the wall Your arm is indeed exerting force, and its purpose is to overcome gravity.
Arm posture conducive to water sense: high elbow
What is the arm posture that is conducive to the formation of water? Let's take the above picture of the palm propping on the wall in the water as an example. If the body is going to move smoothly, the position of the palm is absolutely lower than the body, so that the body weight can be effectively transferred to the palm to form a stable support point. High elbow paddling (elbow is higher than palm) is the best way to allow the arm to effectively support weight. But if you just draw the gourd with the high elbow like the picture above, it will become like a crawler on the treadmill and move the water like a crawler.
The way to create a solid sense of water in the water is to effectively transfer the body weight to the support point of the palm of the forearm. This is the fundamental way!
Starting point for the formation of water
After understanding how the sense of water is formed, you will of course want to ask: How can you practice to strengthen the sense of water?
Before the actual practice, you must also know that the starting point for the formation of water sense is just the moment when you start to lift your arm. Why? Because the weightlessness caused by the boom will suddenly pressurize the forearm, the pressure will make the water solid.
In other words, the timing of the formation of water sense is at the moment of catching the water. I remember the years when I was still learning freestyle. The senior sister of the swimming team often said to me: "It is very important to catch water! "White stroke." Although it seems that grabbing water is a "hand" movement, the water feeling formed in the palm is actually caused by the sudden weight transfer to the palm when lifting the arm.
How to maintain a consistent sense of water
After lifting the arm, the shoulder on the same side rolls out of the water. Because part of the body volume is out of the water at this time, the buoyancy is reduced, resulting in a weight that is instantly greater than the buoyancy. Therefore, the key to maintaining the sense of water is whether you can continue the shoulder. "Pressure", and this pressure is transmitted to the water grab arm. This pressure caused by weight loss due to shoulder rotation will make your stroke arm press on the physical object (like the example of the wall mentioned in the front), the more surely you can conduct the "pressure" during "weightlessness" The more you can grasp the "real sense of water" when you stroke your arm.
