Swimming skills | why does the body sink as soon as you paddle?

01
Some people say that when they swim, as long as their arms stroke, the body will sink obviously, but the stroke is very good, and the water walking effect is also good, but when they stroke, the upper body will float up obviously, causing the lower body to sink, so they can only offset the sinking trend by kicking. Why?

After the stroke, the water walking effect is the best. The leg water action breaks the water walking effect, but the body will sink again without the kick. Swimming is like swimming with a limp, and the speed can’t be raised.

If we follow the practice of full immersion freestyle, we don’t need to practice kicking at the beginning, and only rely on the good cooperation of two arms, we can solve the problem of “limping swimming”, and the speed will also be improved.

02
The division of labor between the two arms is different

According to the practice method of full immersion freestyle, one arm pushes the water, and the other arm stretches forward stably, which can play a supporting role.
Many people’s problems in the early stage of learning freestyle are related to the forearm, mainly due to the lack of understanding of the supporting role of forearm.
When we talk about the arm, we think of the stroke, but forget the more important forward extension.

Key points of cooperation between two arms

Only when the forearm and the paddle arm cooperate well, can they swim efficiently and easily. When the paddle arm pushes the water to the front, the forearm should be further extended to the front.
The most important thing to reach forward is to relax and be patient, waiting for the stroke to end.
The most important thing of the stroke arm is to hold the water and push it straight.
Stretching and pushing should start at the same time and finish at the same time. When practicing, pay more attention to the effect of body side turning on the synchronization.

The main points of forward extension and stroke

For full immersion freestyle, the position of the forearm in the water directly affects the ups and downs of the legs.
Because everyone’s body shape and fat distribution are different, and the position of the body center of gravity is also different, so, at the beginning, do a solid job of full immersion basic practice, and find the most ideal forward position of your arm in the water.
There is a key point in the stroke: push the water straight to the rear as far as possible. When the current arm is extended into the stroke arm, you can rotate the shoulder and the arm to generate force, which is conducive to increasing the power of holding and pushing the water.
However, there are always various problems when practicing in the water. For example, before the other arm completes the stroke, the forearm becomes the holding arm and the stroke arm; The position of forearm in the water is not accurate; When the arm is extended forward, the fingertips will point toward the water surface, forming a “brake” action.
One of the most simple and effective ways to solve these problems is to keep your eyes fixed on the palm of your arm or the back of your hand.
At present, when the stretching arm and the stroke arm do a good match, the upper and lower body of the body is balanced, floating on the water like a flat board, even if you don’t kick, you can easily swim.
