Flange's ear pressure balance technique exercises in freediving

Part 1: Physiology

A. The channel that connects to the lungs is called the trachea, which is controlled by the epiglottis bone (also known as the larynx cap).

B. The channel that connects to the stomach is called the esophagus. It can be turned on or off. Most of the time, except for swallowing food, is closed.

C. The flow of air into and out of the lungs is caused by soft patella (Soft

Controlled by the palate, if the soft palatine bone is in the usual position (as shown above) then air can freely flow through the mouth or nasal cavity.

D. If the soft patella is in an ascending position and the nasal cavity is in a closed state, then air can only flow from the mouth.

E. If the soft patella is in a descending position and the mouth is in a closed state, then air can only flow from the nasal cavity.

F. The opening of the Eustachian tube is located in the nasal cavity. The key to balancing the ear pressure is to force air into the Eustachian tube.

Part II: The Essentials of Action of the Francis Method

The following figure shows the cross-sectional anatomy of the human head when using the Francis method:

The tongue moves back and forth through the base of the tongue. The tongue moves like a piston. The entire air volume at the throat is squeezed. The air must have

Released. At this point the air in the throat will try to flow to the lungs, but the epiglottis bone has been closed, the air will try to flow to the stomach again, but the esophagus has closed, the air will flow upward again through the nasal cavity, but the nose has been pinched by the fingers In the end, the only place where air can go is the Eustachian tube. The only limit to the force that forces air into the Eustachian tube is the strength of the tongue. The power of the tongue is incredibly powerful. The air pressure it provides is sufficient to rupture the middle eardrum.

To complete the Francois law, you must:

1. Hold your nose.

2. Fill your mouth with some air.

3. Turn off your epiglottis bone.

4. Make your soft cheekbones fall into the usual natural position.

5. Move your tongue like a piston and force the air to the throat.

Unfortunately, most people do not know how to control the pressure and soft cheekbones, nor how to move the tongue like a piston.

This article is to describe how to learn the above steps in a step-by-step process. If you are proficient in every step, you will be successful.

The steps to practice are as follows

1. Learn to fill the mouth with air.

2. Learn to control the epiglottis bone.

3. Learn to use the tongue.

4. Learn to move the tongue like a piston.

6. Learn to control the epiglottis bone and the soft patella independently.

7. Comprehensive exercises.

8. Test in water.

9. Learn advanced changes.

Step 1: Learn to fill the mouth with air

Inhale in the mouth, until the cheeks bulge for a few seconds, and then use the power of the cheek to press the air into the lungs. Repeat the above steps until you are skilled.

Do action - [complete cheeks inflated], inflate your cheeks until you feel like you're going to explode

Do action - [soft cheeks], inflate to your cheeks until you are about to begin to swell

When I say [fill your mouth with a little air], I mean [gentle cheeks are aerated]

Step 2: Learn to control the epiglottis (throat cover)

There are many ways to control epiglottis bone

Method 1 rinsing or drinking water

Drink a small sip of water

2. Head back, do not let water pass your throat, do not swallow water.

3. Water cannot enter your throat because you have closed your epiglottis bone.

Method 2: Exhale but stop exhaling

1. Open your mouth and make it bigger

2. Exhale, but do not let any air exhale. (Translation: that is, the lungs exhale, but with the throat shut)

3. In other words, "Close your throat and use your breath to fight your throat.

4. No air flows because you have closed your epiglottis bone.

Method 3: Inhale but stop the air

1. Open your mouth and make it bigger

2. Inhale but do not allow any air to enter your lungs.

3. In other words, "close your throat and inhale against your throat

4. No air enters your lungs because you have closed your epiglottis bone.

Method 4: Epilogue Bone Music

1. As in Method 2. Exhale against your throat and continue to pressurize.

2. Let the breath pass through the throat instantaneously, and then stop instantly, again and again, sounding like a noise that deliberately causes the throat to live.

3. Let the air exhale and stop, and again and again, exhale, stop, and try to get as fast as possible.

4. The part of the muscle you control is the epiglottis bone.

Method 5: Epilogue bone music (inhale)

1. As in Method 4, but change to inhale, stop, inhale, stop, and continue to practice Method 4 and 5 repeatedly until you are able to control

Systemic epiglottis bone.

Step 3: Learn to Control Soft Tibia

1. Close your mouth

2. Inhale from your nose

3. Exhale from your nose

4. Inhale from your nose again

5. Open your mouth

6. Exhale from your nose. At this time, there should not be any air spit out of your mouth.

7. Inhale from your nose. At this time, there should not be any air inhaled from your mouth.

8. Open your mouth and keep breathing only with your nose.

9. Then just use your mouth to breathe and don't let any air flow through your nose.

10. Once you are certain that you can use your mouth or nose to breathe very easily (in the open mouth state), perform the next procedure.

11. Take a deep breath

12. Keep your mouth open

13. Only slowly exhale with your mouth

14. Exhale continuously and keep your mouth wide open, breathing only from your nose.

15. Exhale continuously and replace it with your mouth.

16. Keep breathing slowly and switch as quickly as possible between the nose and mouth.

17. Try the same method, but change to inhale, keep your mouth open, and switch as quickly as possible between the nose and mouth.

18. When you switch your nose and mouth movements, you will feel a soft muscle movement at the back of the throat, which is the soft cheekbones, when the soft cheekbones

When you rise, you exhale from your mouth, and when the soft cheekbones lower, you breathe from your nose.

19. Continue the above exercise until you can skillfully "rise" or "drop" your soft cheekbones.

20. When you breathe out both mouth and nose, your soft cheekbones are in a natural position (not above and below).

Step 4: Learn to use the tongue

Now you have to learn how to block the airflow in the mouth with only your tongue

1. Exhale from mouth

2. Close your mouth and stop the airflow in your mouth (your cheek will immediately pop up at this time)

3. After inhaling again, start breathing again.

4. Use epiglottis to stop the outflow of air.

5. Now that you have learned two ways to prevent air from flowing out of your mouth: use the mouth or epiglottis bone.

6. Now you can learn a third way to stop the flow of air out of your mouth.

7. Inhale slowly and exhale from your mouth, try to send out the syllable of “th” in the word “theatre”.

8. Hold the tip of the tongue against the upper gum and keep the tongue in this position.

9. Try to block the air flow with your tongue. The position where the tip of the tongue is against, approximately at the back of the upper gingiva, above the caries (the edge of the tongue is inside the caries). Guessing means the tongue is rolled up and back.

10. Repeat the above steps until you can stop the air from your mouth with your tongue.

11. Make sure you do not use the way to close the epiglottis bones or close your mouth. Your lips should be open. The jaws are almost closed, or the upper and lower teeth can be touched together.

12. Once you can use your tongue to control the air flow, the position of the tongue and its technique, it is called "tongue movement".

Step 5: Learn to use the tongue like a piston

1. If you do not know how to compress your lungs, please refer to "Appendix A"

2. If you can easily compress your lungs, go to the next step.

3. Find a breathing tube first

4. Bite the breathing tube with your mouth

5. Hold your nose

6. Compress the lungs with a breathing tube

7. You won't be able to compress with your cheeks. That's no use. You have to use your tongue.

8. In other words, use a breathing tube to inhale, use tongue motions, raise your tongue backwards, and press air into the throat and lungs.

9. To perform this action, your tongue is pressed against the upper gums and above the molars. Once you can use the tongue to create a "sealing" effect, your teeth will form an external "air chamber" and behind the tongue will form a "back air chamber" when your tongue stays in this position, It will not leak, the tongue can form a compressive effect.

10. Once you can use the breathing tube to compress the lungs (as in the previous steps), you have been able to "move the tongue like a piston." Now you can use the tongue to press the air into your lungs.

Step 6: Learn to independently control epiglottis bone and soft patella

Unfortunately, the epiglottis bone and the soft cheekbones work in pairs. Just like your ears, it is difficult for you to move one ear alone or just one side of the eyebrows. When you turn off the epiglottis bone, yours The soft cheekbones are almost certainly in the ascending position (this is to prevent the air from flowing through the nostrils). The problem is that to implement the "Franz law", you must learn to "close your epiglottis bone and make the soft cheekbones." Staying in the normal position, this part is the most difficult and time-consuming part, and it is also the key to the entire skill.

1. Gently plug the nostrils with your index finger and thumb and breathe out your nose.

2. The air should flow to the nose and cause the nostrils to bulge slightly.

3. Blow in the mouth until the cheeks bulge.

4. Close the epiglottis bone.

5. Try to squeeze the cheeks and force the air to flow to the nostrils.

6. You should feel the air flowing through your index finger and thumb, and the nostrils will pop up slightly.

7. If the air disappears or the nostrils do not bulge, it may be back to the lungs, and you may not be able to close the epiglottis bone.

8. If the air is stuck in place, it means that your soft cheekbones are in an ascending position, which will block your nasal passages and repeat the soft cheekbones.

Learn until you can clearly feel the muscle movement.

9. Repeat the above steps to focus on the soft cheekbones - that is, to keep the soft cheekbones in their natural position. Use the cheeks to force the air into the nose. The only way is to keep the soft cheekbones in their natural position.

10. If you can't implement the above steps, try the following:

11. Gently pinch your nose again.

12. Call out 90% of the air in your mouth.

13. Close your mouth and press the remaining 10% of air into your cheeks until your cheeks bulge (the cheeks are completely inflated).

14. Turn off the epiglottis bone.

15. Your lungs should be completely empty, your cheeks should bulge, and air should get stuck in your mouth because your epiglottis bones are closed at this time.

16. Press the air slightly toward your throat. There will be no air back into the lungs because your epiglottis bone is already closed. Instead, the lungs develop an extremely uncomfortable vacuum.

17. Keep the lungs in a vacuum, try compressing the cheeks and forcing the air to flow to the nose. Focus on the soft cheekbones, keep them relaxed, and keep them in a natural position. Do not allow air to return to the lungs.

18. Exercise with the above steps until you are very skillful when the epiglottis bone is closed, the soft cheekbones remain in the natural position, that is, the muscle state you must be familiar with. Another way to practice independent control of the epiglottis bone and the soft cheekbones is to compress your lungs. In other words, you don't need to use your mouth to compress your lungs. You have to use the nose to “suck” the gas.

Step 7: Comprehensive Exercise

Hold your nose

2. Pinch your cheek for a moment.

3. Close the epiglottis bone and keep the soft cheekbones in a natural position, just as you have just learned.

4. Just as you practice compressing the lungs with a breathing tube, using the technique of tongues, the air will be forced to the throat, the air will not enter the lungs, but will enter the nasal passages - but because you have pinched your nose, the air will Enter the Eustachian tube, which will lift your eardrum.

5. Once your eardrum is open, you can use the tip of the tongue to apply pressure and stretch the eardrum outward. In fact, if you apply continuous pressure with the technique of the tongue, it will break your eardrum! (Of course, don't try to break your eardrum). Continue the above exercises on land until you can open the eardrum quickly.

Step 8: Exercise in water

1. Find a swimming pool that is at least 10 feet deep.

2. Dive 10 to 12 inches on your head and feet. Your ears will feel slight pain.

3. Now hold your nose with your hand to balance the ear pressure, you should be able to immediately open the eardrum.

4. Apply pressure with your tongue until you feel the eardrum stretch out.

5. Do the same exercises in the lake or the sea

Step 9: Learn advanced changes

To complete the frenzel method, there must be a gap between the throats, and the tongue must be pushed against the gap like a piston. Without this gap, it cannot be successful. When the potential person dive, his lungs are compressed, and when it rises, the remaining compressed air will rise to the lungs. When it reaches a certain depth,

The unconscious will suddenly find that the air between the throats is not enough to complete the frenzel method. This situation will happen if the head and foot postures occur, but the posture on the lower head will occur more quickly. The actual depth of this "failure" varies from person to person. The shallowest depth I have ever heard is 25 meters. In order to break through this so-called "depth of failure", the air must be moved to the throat. This action can be easily achieved by contracting the abdomen, which closes the mouth and presses the air into the mouth. This will cause the cheeks to bulge once in the mouth and cheeks. With air, the epiglottis bone must be closed before the air returns to the lungs. If the epiglottis bone is closed and the air is trapped between the throats, frenzel can be done. The above technique, commonly called "frenzel", is used by almost all large-scale free-diving divers. However, even with the "frenzel" method, There must be a depth where the air in the lungs is so small that it cannot be inflated between the mouth and throat. After this depth, it is useless to use the “frenzel” method.

The only way to balance pressure is to keep enough air in the mouth and cheeks. Before reaching that depth, perform the following steps:

I call the "frenzel fattah" technique.

1. Find out the depth of failure of your own "frenzel" method, which is generally between 50 and 90 meters. Let us set this depth to x meters.

2. Set the depth warning of your dive watch to (x-15) meters. That is, if your failure depth is 60 meters, then your depth warning is set at 45 meters.

3. Start dive.

4. When you hear a deep warning sound, lean forward, contract the abdomen, press the air into your mouth, and your cheeks should have fully bulged.

5. Immediately close the cheekbones and keep the epiglottis bones closed during the entire dive. You will find that it is very hard to put pressure on the epiglottis bone with air.

Useful, can help the epiglottis bone tightly closed.

6. Keep the soft patella in its natural position. You can use the frenzel method to maintain the balance pressure. You must continue to maintain the epiglottis.

Bone closes.

7. You must be able to balance your mouth and cheeks three or five times.

8. Surprisingly, using this method, your lungs will completely shrink (or crash) and be filled with fluids, yet there are still in your mouth

A lot of air to balance, you can use the air in the mouth to do mirror balance. To practice this technique, don't hold your nose

child. You can practice "frenzel fattah" in the pool, but it is very dangerous. You must have a buddy or someone to watch.

1. Find a pool that is at least 10 feet deep.

2. Get ready to relax.

3. After appropriate breathing adjustments, exhale 95% of your air.

4. Close your mouth.

5. Press the remaining 5% of air into your mouth and your cheeks should bulge.

6. Immediately close the epiglottis bone.

7. Dive to the bottom of the pool.

8. Balance the pressure with the air in your mouth.

9. You can practice in the lake or the ocean. Use only the air in your mouth and you should be able to dive 10-20 meters.

Appendix A: How to Compress Your Lungs

1. Close your mouth.

2. Press the air into your mouth and fill your cheeks.

3. Compress your cheeks and force the air back into the lungs.

4. Repeat the above three steps until you have enough cheeks and can easily push air back into your lungs.

5. Find a drinking straw.

6. With a straw.

7. Suck with a pipette. (Transfer: sucking into the mouth like a sucking bottle)

8. Inhale with a pipette. (Translation: As usual, the nose sucks into the lungs, but here it sucks)

9. Note the difference between the two.

10. Inhale to your maximum amount. (in 8. way to inhale to no longer able to suck)

11. Use a pipette to suck air into your mouth.

12. Remove the pipette.

13. Use the cheeks to push the air back into the lungs.

14. Use a mouth to suck the air without a straw.

15. Compress the air back into the lungs with your cheeks (don't swallow the air in your stomach).

16. A suck/push stroke is called a pack.

17. Restart the previous trip (without straw)

18. Inhale to your maximum amount.

19. Compress your lungs, again and again, until your lungs can no longer fit in any air, or you feel uncomfortable, and calculate how many compressions you can do. If you have a spirometer, you can measure how much extra air you can get.

0.8 to 4.0 liters of extra air
