Swimming includes diving. How to practice breathing correctly?

Before diving, you need to be fully prepared to breathe on the water, so that you can stay further downstream. Specifically, take a few deep breaths before diving, increase the oxygen content of the body, and take enough air before entering the water. There are four parts of the human body that can store air: abdomen, lungs, throat and mouth. When inhaling before entering the water, you can inhale first, then stretch your chest and inhale, and then look up and inhale, so that you can take three deep breaths. Finally, you can have another powder puff on your cheek, but it's not good-looking, and it's not very helpful to prolong snorkeling time. Generally, you won't see who has this kind of face for snorkeling.

Many people say diving is not difficult. In the swimming pool, you can push the wall and dive. In the deep water area, you can learn diving (duck diving). I have answered questions about diving before, so I won't say much here. It's hard to keep diving after diving, and it's hard to make your body float. This requires mastering diving skills, which will be explained in detail below. Exhale slowly while underwater. When you feel breathless, exhale slowly for several times, which can greatly extend the time of underwater diving.

There are usually two kinds of diving, one is breaststroke and the other is dolphin swimming. If the water depth is not very deep, use the long stroke of breaststroke, but at the end of the stroke, turn your wrist and palm up, so that you can press your upper body into the water through the stroke and keep your body afloat. When the water is deep, the arm can't row long. After your arms are over your chest, take your arms back and push the water backwards. Because the underwater pressure is relatively high, long-distance travel is easy to cause lung compression injury. Dolphin diving is just diving underwater with butterfly legs. The trick is to streamline your body. Hold your head with your arm and hit the dolphin's leg with your leg. When you swim, your hands will guide you, that is, press your hands down first, and then drive your head, shoulders and trunk. With the help of butterfly legs, you can swim forward in an undulating state. When you swim in, the person who controls the downward pressure on your torso will not float up. Try to relax. Try to relax underwater. Too much tension can easily lead to unnecessary oxygen consumption, and it is also easy to accelerate oxygen consumption caused by fast action frequency. So when diving, you must relax slowly.
