Here's an explanation from Ken Tamplin's forum: Inhaling: The diaphragm contracts to help draw air into the lungs. When the diaphragm contracts, it moves downward, increasing the space in the thoracic cavity (chest cavity). This creates a vacuum that causes air to flow into the lungs. As the diaphragm presses downward, it pushes the organs in the abdomen outward, causing the stomach area to extend or "bulge" slightly. This is particularly noticeable during deep breathing, as the diaphragm's movement becomes more pronounced. This type of breathing is often referred to as diaphragmatic breathing or "belly breathing," and it allows for a more efficient intake of air compared to shallow chest breathing. Exhaling: When the diaphragm relaxes, it moves upward, decreasing the space in the thoracic cavity, which helps push air out of the lungs during exhalation. To control the rate of exhalation, you primarily use several muscle groups that help regulate the flow of air out of the lungs: 1. Diaphragm: While the diaphragm is mainly involved in inhalation, controlling its relaxation can also slow down exhalation. 2. Intercostal muscles (internal intercostals): These muscles, located between the ribs, assist in controlling exhalation. The **internal intercostal muscles** help compress the rib cage during active exhalation, reducing the volume of the chest cavity and pushing air out of the lungs. 3. Abdominal muscles: The **rectus abdominis**, **transverse abdominis**, and **obliques** are engaged during controlled or forceful exhalation (like during singing or speaking). These muscles help push the diaphragm upward by contracting the abdomen, which helps expel air more DELIBERATELY. 4. Accessory muscles of expiration: In cases of forceful exhalation, such as during coughing or vigorous physical activity, additional muscles like the **latissimus dorsi** can assist in controlling airflow. In singing or speech, all these muscles work together to precisely control the pressure and airflow which is the rate of final exhalation. In volume 3, Compression is introduced. Through the mastery of all of the above and without introducing tension in the neck, face, or head, compression is the delivery to the vocal cords only the amount of air necessary to produce the desired tone.
Thank you so much for the beautiful video. I would like to add a few things - There is a tendency to think that 'correct' breathing is diaphragmatic breathing This is an assumption that is true for states of calm and sleep. When we are active the prevailing breathing is rib breathing. Another important thing - many times the back and neck are held and limit the expansion of the breath backwards. When you are aware of sharing the back with the breath, the breath will affect the expansion of the back and allow mobility in the nape of the neck and back between the shoulder blades. Iwill be happy to collaborate on this important subject.
Yes, the rigid spine needs to be bought into motion! the curve of the spine as it is pushed back, keeps the ribs balanced, well the whole body balanced, and the winging of the lower edge of the ribs as the spine curves and the fluid motion pushes the ribs open.
A great video and truly enlightening x thank you. I never ever visualised the intercostals before. Maybe you could show the serratus muscles in the next one ?
Great job! Very helpful. I am a movement specialist/PT . This video will be an excellent visual ad to help people understand where the diaphragm is and how it functions.
I am currently teaching postpartum yoga and would love to visually demonstrate the coordinated function of the diaphragm, pelvic floor, and transverse abdominis (TA) to my students. Thanks!
thank You for Your , I’m not expert on the subject, but if you have some research that you can point me, I will eventually look into it because a lot of people wanna see this animation thanks so much. Have a good one.
La meilleure représentation graphique de la respiration diaphragmatique que je connaisse et qui montre que le ventre ne "se gonfle pas" sur l'inspiration, ce qui est exact
This is a great anatomy video. I like how you incorporate the intercostals. The only thing that I see that can easily misinterpreted is when you add the abdominal muscles overtop the movement appears to be more apical and almost like when the diaphragm contracts it is elevating instead of depressing which is very similar to apical dominant breathing patterns.
I like this in relation with contraction. Would be beneficial to be described even the correlation with the spine as i consider there happens to appear pain which commonly is misunderstood.
Stunning video with a very clear explanation. I agree with requests below that it would be great to show what is happening with body motion below the lower rib level as a result of diaphragm motion.
Thank you very much for this amazing video. It would be great to have a video that shows the movement of the internal organs, as well as the coordinated movement of the lower diaphragm and the chest diaphragm, will visually demonstrate how breathing and movement occur. This will provide a clearer understanding of processes such as pelvic congestion, the development of varicose veins, and diseases of the female reproductive system. One of the root causes of these conditions is a disruption in the breathing cycle.
Thanks for this and your other excellent videos. It would be good to include the right and left crus of the diaphragm and their connection to L1 - 3. Most people are quite contracted in the lumbar area and one of my tasks as an Alexander technique teacher is to help people to organise the body so that the lumbar area uncointracts and expands allowing further excursion of the diaphragm (as wll as reducing low back pain.)
Very good. Thank you. The deeper structures (eg intercostal intime) are more interesting to me than the much studied superficial musculature. My thinking is that we can learn most about human function by starting at the innermost parts and working outwards; the reverse of the traditional way anatomy is learned. The surface responds to the interior. Knwoing and understanding the deep layers informs what we see on the surface. I am more interested in function than form.
Thank you for this video. I saw a video saying that the diaphragm is attached to the heart so that it really only moves up and down less than half an inch and that most of the movement is going out to the sides. This seems a little different than your presentation, which talks about the diaphragm moving up and down about 2 inches . What do you think about this?
thanks for your feedback- I was going with an article that had an ultrasound picture of inhale and exhale phase, but what you say also make sense. probably I should let the center of the diaphragm stay more at the same height and balloon the side more! I ll do an update on this in future and will incorporate this,.. thanks so much for pointing this out! have a good one alex
I would like to collaborate with you; I am a voice teacher and use the conscious/ physiological method of using the diaphragm ; as opposed to blocking it or pushing down like in some outdated vocal techniques: As u implied the effect on mental health and mood disposition are an interesting point to elaborate on
that sounds interesting even though I don’t see that you really have a RU-vid channel. If you want to please go to my homepage and elaborate a little bit more. On my custom Order Page I do have an inquiry from just send it to me so I will have your emails and we don’t have to do this over chat here,.. Greetings, Alex
I love your content. My only concern is that showing the more extreme form of breathing (ribcage in more of a full expansion and contraction) leaves the viewer with a false impression of how breathing looks in relaxed states. The reverse is true. The upper rib cage is not involved in relaxed breathing; only the lower ribs provide the primary movement. In other words, healthy breathing doesn't look like your video, and it, in fact, looks far more subtle. I know this video is merely for demonstrating the anatomy, but I fear we are sending the wrong message when we keep incorrectly showing people how much the ribs need to move in healthy breathing.
Thank you for your feedback. I disagree with your assessment. The animation does not depict extreme breathing; rather, it illustrates an averaged-out range of motion at a steady pace. This depiction is neither incorrect nor unhealthy. In fact, a healthy human should be capable of breathing in this manner. My intention is to show the anatomy and mechanics of breathing, and I believe this representation accurately reflects a functional range of motion.
In my movement practice I am seeing issues when people don't exhale completely and don't know how to relax the diaphragm. It puts them in an extended position which compresses the thoracic spine and creates a lot of issues traveling up and down the chain. I feel if they have to come out of those pains and issues it is important to address their inability to relax the diaphragm and correct it. Can you please explain if there is an anatomical difference in the size or capacity of the right and left diaphragm and the lungs ??? Which results in the human body being right dominant or asymmetrical???
@@mailsandymurali The diaphragm and lungs are anatomically asymmetrical, contributing to the body's natural asymmetry. The right side of the diaphragm is higher and thicker due to the liver beneath it, while the left side is lower, accommodating the stomach and spleen. Similarly, the right lung is larger with three lobes, whereas the left lung is smaller with two lobes to make room for the heart. These anatomical differences contribute to overall body asymmetry but don't directly cause right-handedness or right-side dominance, which is more related to brain lateralization.
@@AnatomyLab Thank you so much for clarifying. I wonder if you have heard about PRI- Postural Restoration Institute and their concept explaining the right left imbalance in the body while moving caused by the asymmetry of the diaphragm and lungs. If you have any take on it please think about creating a video around that concept. And about the mechanics of the pelvic diaphragm while breathing and the interplay of diaphragm and pelvic floor. Thank you for your great work.
Hi, my diaphragm on my left side is moving vigorously and it seems like some organs inside me are moving and it causing me a lot of pain on my side. Please I need an advise and a prescription please. 🙏🙏
