How to play diving? How to dive and swim?

1. Precautions before diving.

Develop a good habit of checking your barometer frequently, the lack of air in the gas cylinder is the most critical situation, generally when there is 70 bar of gas left, ready to rise, and when there is 50 bar of gas left, it will rise directly.

2.It's best to learn to dive after you learn to swim and then learn to diveAlthough you don't need to know how to swim, it's best to learn to dive before you get involved in training.

3.Pay attention to protection to avoid injury, beginner diving is easy to ** foot fins wear out ankles, remember to wear diving socks or use adjustable fins, diving boots.

4.It's a good idea to have your own elephant and dive computer to help you get to the surface without worrying about being hit by a passing boat, and the dive computer can tell you how deep you are and how long you can stay in the water.

2. Precautions after diving.

1) When you dive into the water, the water will soak into the snorkel, so you must float to the surface of the water and blow hard to remove the water.

2) Inhale slowly. Blow hard as you exhale. The water in the pipe must be drained in one gas.

3) When diving into the water, do not exhale in the water, so as not to have no air to drain the snorkel after surfacing the water.

Squeezing and draining of the mask.

1) The external pressure increases during submersion, which will cause extrusion. It must be excluded to avoid facial injury.

2) Blow slowly through your nose at this point.

3) Return to normal state.

4) When the mask is flooded, raise your head slightly, press on the top of the mask, and slowly blow through your nose to remove the water.

Use of fins.

1) The fins are used in the same way as the freestyle feet, and the knees should not be too bent and swing widely.

2) Straighten your chest and back, facing forward.

3) Beginners should use softer fins.

How to dive and swim:

1. There are two meanings of diving: one is swimming under water above 5 meters; The other is to dive into deep water below 5 meters for swimming.

2. Diving below 5 meters is a professional diving that requires professional equipment, and well-trained professionals are also required for diving.

Dive above the meter, mainly breaststroke, take a half breath, bow your head, and swim downstream, you can touch and dive; If you inhale a lot and have a lot of buoyancy, it is difficult for people who have just learned to swim to dive; People who often run long-distance and practice breath-holding have a large lung capacity, and can swim more than 50 meters in diving breaststroke.

4. If you want to dive and swim farther, you can take a breath first, spit out half of it, and then take a deep breath, so that you can dive farther, and pay attention to the fact that you can't inhale underwater, you can only exhale slowly with your mouth and nose, otherwise you will choke on water.

1. Choose a shallow water area with a water depth that does not exceed your heart for preliminary exercises, do warm-up exercises before entering the water, and wear a swimming jacket and hat.

2. Go into the water, take a deep breath, exhale, and do 5 deep breaths in a row.

3. Turn on the stopwatch, take a deep breath, start the timer, look at the time and stop the timer when you need to roll this to change your breathing, write down the time, repeat the above steps again, and take the middle value according to the time after 5 times, which is the standard for the underwater breath-holding time.

4. Take a deep breath and press the stopwatch to time it. Squatting in the water, check whether the stopwatch is up to time when you need to breathe, just start to get out of the water according to your own ability, slowly lengthen the breath-holding time one by one according to the time, highlight the air after inhaling and increase the underwater time, the practice time should not be too long, generally practice for 20 minutes and rest for 10 minutes, and the total time is controlled within 2 hours; For a week in a row, you will find that the time has gradually increased.

5. Breath-holding is related to lung capacity, and to better increase lung capacity, you need to participate in more exercise and enhance physical fitness.

Diving is infiltrating, which may be liked by many friends with high disadvantages, but the underwater world is not only full of mystery, but also full of dangers. Let me tell you about it.

Principles of learning to dive:

1. Prepare all your items. Please bring swimwear, towels, toiletries, slippers, etc. when you get off the bus.

2. Listen to the explanation. Spend 3-5 minutes listening to a professional guide explain the dive. There is an introduction to diving on the spot, as well as a diving instructor.

3. Registration. Fill out the registration form, pay the fee, and receive the diving ticket.

4. Change into swimsuits. Go to the locker room with your ticket to change into swimwear. From the moment you receive your dive ticket, there will be a staff member who will arrange it for you and tell you what to do next.

5. Store clothes. Guests participating in the dive can store their clothes free of charge. Slippers should also be stored at this time. Go barefoot to change into a wetsuit. Note: Please store your valuables by yourself.

6. Change into a diving suit. The wetsuit is specially designed. It prevents the body heat from being lost too quickly, so it has the effect of keeping warm on the seabed, and it does not feel cold in the water even in winter.

7. Shore training. This part is the most important, you must listen clearly and figure it out. If you don't understand, ask the trainer until you figure it out. Changing into a wetsuit for shore training will be hotter, and the upper body wetsuit can be pulled apart to breathe through the wind.

8. Launching. Remember: don't be nervous.

Remember what the trainers on shore told you. The instructor will take you down, if you feel uncomfortable in the water for the first time, you can float up, adjust your breathing, and enter the water again. Listen to your diving instructor when underwater.

Learn the posture of diving:

Snorkeling is a swimming style in which the body is underwater and does not swim in with breath. There are deep and long dives. There are many postures for diving, but most of them only use breaststroke *** amateur commonly used *** and butterfly leg Qi Lao diving *** professional commonly used *** Here only the breaststroke front stroke technique is introduced.

Step Method.

First: Body posture.

Frog diving requires the torso and head to be level at all times, but the arms should be slightly lowered to prevent the body from floating.

Second: leg movements.

There is only a small difference between the leg movement of the diving and the movement of the breaststroke leg, that is, the hip flexion is smaller when the leg is tucked and the angle at which the legs are separated to the sides is smaller.

Third: Arm movements.

1*** Stroke: The stroke of the diving stroke is similar to the butterfly stroke, except that the distance between the palms of the two hands is slightly larger, and the direction of the rotation of the palms does not change much, almost completely perpendicular to the water surface.

2*** Arm Move: When the stroke is over and glides for a while, the hands are externally rotated from both sides of the thighs, stretched forward along the abdomen and chest, and when the head is reached, the palms begin to rotate inward, the palms turn downward, and the front of the head is straightened, ready for the next stroke.

Fourth: arm and leg coordination.

During and after the arm stroke, naturally straighten your legs together and slide in the water. Tuck your legs when you move your arms, push your legs forward while moving your arms to your chest, and end your leg press when your arms are straight.

How do I learn to dive? Diving is actually no different from swimming, but we usually pay attention to the fact that diving must be carried out by professional personnel.

Those who have seen it will watch:

1. You can't engage in diving activities after being drunk; People with heart disease, asthma, high blood pressure, otitis media are not allowed to engage in diving activities.

2. Limit the depth of diving.

3. Do not use earplugs when diving.

4. For eye myopia, you can choose diving goggles with the same myopia as you.

5. Several gesture languages that must be mastered when diving: OK, ascending, diving, uncomfortable, poisonous creatures, do not touch.

6. Learn to do counterpressure. When diving, due to the pressure of the water, when diving to a certain depth, you will feel pain in your ears, and you will do counterpressure, that is, there is no pain. Or do the action of swallowing saliva, which can also balance the ear pressure.

Counterpressure method: pinch the nose with your hand from the mask to block the nostrils, then inhale hard, hear a "pop" sound, the air enters the ear tube, and the counterpressure is successful.

7. Keep it far within the safety limit of the computer table or schedule, and try to reserve space.

8. Only engage in one or two times a day'Dive, not more than three dives.

9. If possible, arrange a rest on the third day of the holiday and do not dive.

10. Rise slowly. The rate of ascent within 24 meters should not exceed 10 meters per minute, and the rate of ascent to within the last 6 meters should be as low as 6 meters per minute.

11. Perform a safety stop. A minimum of 3 minutes at 5-6 meters is a reasonable safety warning, while a dive at a depth of more than 30 meters should be at a depth of about 9 meters plus a 1-2 minute stop.

12. Replenish water and maintain physical fitness suitable for diving.
