I'm a beginner and I tried it once and found it couldn't sink at all. What action should be done to make the body sink?Also, barely 2 meters into the water, the ear uncomfortable. How do you adjust the ear pressure balance? Is earplugs useful?
(1) in the water (breath) ventilation techniques: in water is mainly to exhale, nose mouth as the breath (spit) to slow and light; in the water are suction to the main port of nasal suction to supplement, fast and deep.
Diving in the swimming pool is divided into two cases:1, "fierce" plunge into the water, dive into the water, this is the use of "Chong" force based, supplemented by posture.2, from the water to dive, this is the position (breaststroke) based, you need to swim breaststroke techniques and techniques, but onlyTake a deep breath, head to the bottom of the pool, the body tilted downward off, until the target position. It's easier said than done, but it's a little difficult to do. Dive down (including dive and snorkel) needs to have some vital support, but also very proficient in the water transfer (hold) gas skills.
(2) first practice to hold your breath, and breath a long time, we must learn to "save" gas, the trick is: whenever the breath reached the limit, with the above "breath skill" slowly gently exhale, exhale and in the process, at the same time to swallow, put up the gas pressure. A part, then a bit slowly spit (under water must have a breath out of breath). In this exercise, not only can save gas to extend the diving (including diving and scuba diving) time, but also can increase the vital capacity, enhance physical strength.(3) as long as you have mastered the method of exhaling and storing air under the water, you will not be flustered or choked by water. It is easy to dive into the water.
