But that’s all just a starting point and if you are interested in really improving your breathing then you are going to need a proven framework to help you get there.

Luckily for you, I’ve put such a framework together – and it offers you so much more than any other breathing course I’ve found. In fact, it’s a Respiratory Revolution!

Throughout this series of articles, you’ve learned about the importance of the biomechanic of breathing. Now, you’ll often hear a lot being said about strengthening your diaphragm and using it better in your breathing, but you’ve learned there are a lot more muscles involved in breathing other than your diaphragm.

Almost no one else will teach you that though, or how to actually activate those breathing muscles and your diaphragm so you can even start to strengthen them. A very high percentage of the runners I see really struggle to get even the smallest amount of activation, so how are they supposed to strengthen them and move the rib cage well to allow your diaphragm to work in the way it’s intended?

Being able to create and maintain a strong and stable breathing cylinder with a well mobilised rib cage is a fundamental and critical element of functional breathing for running, whether you are able to transition to nose breathing or not.

I cannot emphasise enough just how important this is, and most breathing courses and systems I’ve found only give this a cursory mention at best: they are missing out a crucial aspect to helping you breathe better when you run.

Calm and relaxed, but left behind…

In addition, as good as they are (and there are some amazing courses and systems available) most breathing courses you’ll come across are designed for the opposite of what you need as a runner. They teach you breathing techniques for relaxation, calm, and keeping your carbon dioxide levels low or within a level. This is fantastic for helping to reduce anxiety and bring in a calm mindfulness, but it just doesn’t help you functionally as a runner. Yes, there are elements of calm and relaxation that you need to bring to your running, and you certainly do need relaxed and well-paced breathing. 

But the reality is that as the duration and intensity of your running increases, you build up carbon dioxide in your cells and blood. If you do not learn to tolerate these higher levels, you’ll always need to slow down and you always risk inducing a feeling of panic and paradoxical breathing. This is what makes my framework different:

Functional breathing designed specifically for running

So with that, here is what you’ll learn on the RunTeach Respiratory Revolution breathing course for runners:

The Respiratory Revolution is an 8-week course, with each module becoming available

each week so you have plenty of time to practise without feeling rushed. In fact, as the course is self-paced, if it takes you 16 weeks or 20 weeks to complete, that’s absolutely fine. Once you have access to the course you have it – there is no time limit. This means you can refer back to the lessons and supporting material whenever you like.

The topics covered in the course are built on the elements that you learned about in the quick guide and articles:

• The Biomechanics Of Breathing
• The Biochemistry Of Breathing
• The Neurology Of Breathing

The topic include:

• Course introduction
• Assessments and benchmark
• Why breathing skills are needed for running well
• What is dysfunctional breathing?
• Diaphragm mobility
• Diaphragm strengthening
• The muscles of inhalation
• The muscles of exhalation
• Why nose-breathe? Discovering the benefits
• Nasal decongestion
• Learn to nose breathe and avoid the panic of air hunger
• Running specific breathing background and techniques
• Breathing Challenges throughout the course to help you learn to breathe better, more quickly

Every module has practical exercises designed to help you improve your breathing right from week 1.

There are also supporting lessons taking you through topics to help you get the most out of the course. For example, do you panic if you hold your breath? Well, I include techniques to help you get over this so that you can take full advantage of the breathing challenges and exercises.

So if you are ready to take the next step on your breathing journey, you can find the course here.

The post Pulling it all together – A framework for better breathing appeared first on RunTeach.

In this article we are going to build on what you’ve learned in the free quick guide to breathing ebook and the first four supporting articles that expand on each topic in the book. We are now going to look at nose breathing: what it is and how it can benefit you both in your running but also in everyday life.

We’re going to begin by looking at some of the common benefits of nose breathing in general and then you’ll discover why these are important. We’ll also uncover why you may not currently want to nose breath and how to go about changing that. Finally, you’ll learn a nose breathing exercise and protocol that you can begin using right away. So, let’s get started.

Nose Breathing Benefits

Some of the common benefits often cited about nose breathing are:

• Filters the air and helps remove allergens and dust
• Warms the air
• Humidifies the air
• Pressurises the air

All of these sound great, and they are, but there is so much more that isn’t often highlighted unless you begin to dig deeper.

• Helps to induce relaxation: When you breathe through your nose the air is slightly restricted which helps to slow down your rate of breathing and encourages better regulation. This slowing down and breath regulation is what promotes relaxation.
  
  However, due to the restriction of the airflow through your nose, you may find this creates some air hunger – a feeling that you don’t have enough air coming in. This can then cause mild panic and lead you to believe that you simply can’t nose-breathe. This is particularly the case if you often suffer from a blocked nose. But you can relax as we’ll look at ways that you can get over this feeling and start to nose-breathe without the panic.
  
• Improves cognitive function: There is some research that supports improved brain function through improved breathing. Actually, the study looked at people with dysfunctional nasal breathing and measured impaired cognitive function leading to the conclusion that efficient nasal breathing helps overall cognitive health and avoids impaired cognitive function. How you breathe also influences the neuroplasticity and predictive models of your brain, so it makes logical sense to deliberately and positively influence these with efficient breathing rather than to leave it to chance.
  
• Smell is important to us in mapping out our environment in the same way as vision and hearing are. The more efficient you become as a nose breather, the more improved (in general) your sense of smell becomes. If you remember back to the article where you learned about the predictive brain, you’ll begin to understand why a good sense of smell is important in helping to provide your brain with the most helpful information it can get. There is some research that links nasal breathing to improved visuospatial awareness, particularly in a sports environment. It does this through synchronising electrical activity in the brain on a wavelength that appears to improve your visuospatial awareness.
  
• Improves the recruitment of your diaphragm which leads to more efficient breathing and is strongly linked to the biochemical aspects of breathing. A strong and well activated diaphragm has also been linked to improved midline stability, something that is very important when you are running.
  
• Increased oxygen uptake in the blood: Nose breathing is more effective at increasing oxygen uptake than mouth breathing. This is something we’ll look at in a bit more detail later on in this article, but for now it’s helpful to know that arterial pressure of oxygen in people who consistently nose breathe increased by 10% over those that don’t.
  
• Production of nitric oxide: As you breathe in through your nose, you produce a molecule called nitric oxide which helps to maintain healthy lung function and may protect against certain respiratory diseases. Nitric oxide also helps to open up your airways, maximising the available oxygen for transfer to your blood and working muscles.
  
• Dilation of blood vessels: Nose breathing helps to open up the blood vessels in your lungs that then improves the amount of oxygen being carried around the body and to your working muscles and other tissues.
  
• Improved blood distribution in your lungs: The nitric oxide produced when you nose breathe helps to improve how your blood is distributed throughout your lungs which has been shown to improve blood by up to 24%. This is particularly the case with the upper areas of your lungs where gravity may otherwise present a challenge to the gas exchange process. Essentially, nose breathing is helping to improve the diffusion of blood from your lungs across into your blood.

I could continue with many more functions of the nose, but this is enough for us to start looking at a little more detail into some of these things so you can begin reaping the benefits of breathing through your nose in a more consistent manner.

Increased Oxygen

Let’s start with increased oxygen because this can seem a bit at odds with the restricted airflow of nose breathing compared to mouth breathing. However, with the help of a small formula it’s easy to see why nose breathing facilitates more oxygen availability. 

When we are exercising hard it’s easier for us to take air in through the mouth because we basically get more air in than we do through the nose. However, if you also speed up the rate of your breathing, you actually end up with less available oxygen. Here’s how it works:

Let’s say you are breathing through your mouth and you are breathing at the typical resting rate of between 12 and 20 breaths per minute. Let’s actually say that you are at the healthier end of this scale and you are breathing at 12 breaths per minute.

The amount of air you take in each breath that is usable is known as the tidal volume (TV), and the total amount of air taken in one minute is called your minute ventilation (MV). The typical minute ventilation is around 6 litres: that is, you take in around 6 litres of air per minute. This is represented in the formula below:

Respiratory Rate * Tidal Volume = Minute Ventilation

RR * TV = MV

12 (breaths per minutes) x TV = 6 litres

So TV must be 500ml of air per in breath:

12 x 500 = 6000ml = 6 litres

But, not all of the air you breathe in a single breath can be used for oxygen transfer. Around 150ml per breath remains in various areas of your throat, trachea, bronchi and bronchioles. This is known as dead space air and it cannot be used for gas exchange. So our tidal volume now becomes:

12 x (500 – 150) = 4200ml = 4.2 litres.

That’s 1.8 litres of air that cannot be used for oxygen exchange in the lungs.

Nose breathing generally encourages a slower breathing rate, typically between 6 and 8 breaths per minute, and at rest we are really aiming for a respiratory rate of 6. However, the amount of air coming into the nose remains the same as the mouth breather in the first example as they weren’t overbreathing, something we’ll look at next. So the total amount of air coming in in one minute is still 6 litres.

The amount of dead space air is the same as before, but our calculation now looks like this:

6 x TV = 6 litres

6 x 1000 = 6000ml = 6 litres

6 x (1000 – 150) = 5100ml = 5.1 litres

So you can clearly see that by slowing down your breath rate to around 6 breaths per minute from 12 breaths per minute, you are gaining an extra 20% of air that can be used for oxygen exchange. 

Of course the question is: “if I’m a mouth breather can I slow it down and get the same benefit?”. In theory, yes. In practice though, slowing down your breathing when just breathing through your mouth is hard to achieve on a consistent basis. You also won’t get the other benefits of nose breathing such as filtration and the very important nitric oxide.

So, nose breathing combined with slowing your respiratory rate is the preferred method of increasing oxygen in your blood. Doing exercises to help with the pacing of your breathing, such as those you learned in earlier topics in the guide and articles, will help you maintain good pacing in your breathing as your exercise intensity increases.

Over-breathing

You’ve just learned that slowing down your breathing rate can increase the available oxygen for gas exchange – something that is very important when you are running because you need to maximise the amount of oxygen that gets to your working muscles and other tissues.

So, why can’t you just take bigger breaths through your mouth to achieve the same thing? Well, apart from losing the benefits of nitric oxide you will also be breathing in too much oxygen. Not a bad thing you might think, except that it will displace the carbon dioxide in your blood (hypocapnia) and that certainly is not a good thing if it happens over longer periods (hours or days) – so you don’t want to be relying on large mouth breaths to get the oxygen you need.

To understand the issue of persistent hypocapnia (as opposed to deliberate, short term hyperventilation training for a few minutes at a time), we need to refer back to the previous article on biochemistry that included an explanation of your energy systems. If you remember, the higher the intensity of your running the harder it is for your body to get oxygenated blood to your cells. As a result, carbon dioxide builds up and eventually you will get to a point where the cells don’t work well and you’ll be forced to slow down. In practice, this is like starting your 5k race way too fast, rising quickly from aerobic to lactic and possibly to alactic, only to blow up a few minutes later and then having to settle down into a more sustainable pace in your aerobic or lower threshold zone. During this high intensity phase there is a build up of carbon dioxide, or a hypercapnic situation. This is the opposite of what happens when you over-breath, but being in a high intensity situation can force you to hyperventilate and over-breathe to compensate for the carbon dioxide build up and leave you in a carbon dioxide deficit.

As part of the normal cellular processes, the carbon dioxide that is shuttled from your cells is combined with water in the blood to form carbonic acid. The next reaction is to disassociate into H+ (hydrogen ions) and HCO3 (bicarbonate ions). This creates an alkaline buffer that neutralises changes in your blood’s acidity. When you hyperventilate or even just over-breath through large mouth breaths, you start to remove a lot of carbon dioxide. This leaves an excess of bicarbonate ions and a deficiency of hydrogen ions. At the same time, your breathing volume decreases to help restore your carbon dioxide levels. However, this will only work during short-term hyperventilation bouts as you return to normalised breathing quickly, allowing those carbon dioxide levels to settle. With continued hyperventilation or over-breathing, you end up in a constant state of hypocapnia and this impacts on your blood’s pH levels. As a consequence, your kidneys start to offload the excess bicarbonate ions to try and normalise your blood’s pH, making them work harder to maintain this fine balance.

In addition to your blood pH levels, the low level of carbon dioxide can cause other issues. Carbon dioxide is a strong catalyst for releasing oxygen from your blood into your cells, so by over-breathing you end up doing the opposite of what you may think you are doing. It is also a dilator of smooth muscles, the kind of muscle found in some of your airways. Therefore, over-breathing can actually restrict some of your airways, further reducing the effectiveness of your breathing.

Essentially, over-breathing other than when doing specific hyperventilation training exercises for a specific outcome, is going to reduce the available oxygen and hamper your running.

Carbon Dioxide Tolerance

Sticking with our carbon dioxide theme and becoming even more running specific, I just want to go back to the energy systems and the build up of carbon dioxide as your effort level increases.

You’ll remember that as you transition from your aerobic system being dominant to your lactic system becoming dominant, the level of carbon dioxide in your blood starts to build up because your system cannot pump the blood fast enough back to your lungs for the carbon dioxide to be diffused back to the lungs for exhalation. This is a state known as hypercapnia where there is excessive amounts of carbon dioxide and eventually this will help create an environment where your cells cannot perform well so you are forced to slow down so everything can begin to normalise. This feeling of not getting enough air in is called air hunger and you can actually use this state to improve balance and brain function – but that’s for another article.

The good news is that you can increase your tolerance to this CO2 build up so that you can push on for longer in this transition zone between energy systems. Ultimately, this means your speed endurance improves and therefore your race times. Even if you are not motivated by running faster and instead want better endurance, being able to operate for longer with a higher CO2 level means you are more fatigue resistant as you are overall much more efficient.

And the starting point for increasing your tolerance to higher levels of CO2 is by nose breathing, even at rest. This is because nose breathing naturally restricts the airflow by up to 50% compared to mouth breathing. Right away you are dealing with less oxygen going in and less carbon dioxide going out. This is also why you may find nose breathing, even at rest, challenging at first: you are not used to this build of CO2 and a reduction in O2 so you respond to the CO2 trigger to inhale as your brain perceives holding out as a threat. Remember that your brain is a prediction engine and the predictions it uses are shaped by every moment in your life so far. As soon as you start to train your CO2 tolerance, you are also shaping your predictive models for future reference.

So where do you start with this and how can you progress it?

1. Start with nose breathing at rest as often as you can, aiming to make it a permanent change.
2. You may find it challenging at times, so take a break but always go back to it and push yourself that little more. Nose breathing will actually help you to open up your airways (remember nitric oxide?) so persisting with it is the key.
3. Begin to build in nose breathing when you are walking, which will present more of a challenge as the CO2 will build up quicker and you may experience stronger air hunger. Again, take a break and go back to it. Each time you do this you are letting your brain know that it’s perfectly safe and you positively shape those predictive models.
4. When you are ready, try some nose breathing when you are on your easy runs. This may only be for 30 seconds to a minute at a time, but it’s all positive graining and positive reinforcement for your brain to build predictive models from and feel safe.

Nose breathing is such an important part of functional breathing, whether you are running or sitting on your sofa, that ignoring it is like ignoring speed work, strength work and other aspects of your run training.

In the next article I’m going to pull everything together and show you how you can improve your breathing in a step by step framework that also takes into account how you are feeling during some of the more challenging aspects of nose breathing, breath holds and rib cage mobilisation.

The post The Benefits Of Nose Breathing appeared first on RunTeach.

In this article you are going to find out a bit more about some of the chemistry involved in breathing, why it’s important for your breathing in general, but specifically how it can help you improve your running.

You may already know that when you breathe in you inhale oxygen (O2) and when you breathe out you exhale carbon dioxide (CO2). But how does this relate to efficient and functional breathing?

Well, the basic process is that when you inhale oxygen it eventually ends up in the small air sacs deep in the lungs called alveoli. The alveoli actually share a membrane with your capillaries, allowing the oxygen to diffuse across into the blood. From there it is pumped around the body to all of the tissues where it is used to help each cell survive and thrive. In terms of your running, the more oxygen that can be supplied to your working muscles and other tissues, the easier your running will be; also faster and longer. But that’s not the whole story as you’ll discover very soon, but first let’s briefly look at the exhalation process.

As the blood comes back around to the alveoli from being pumped around your body by your heart, it contains carbon dioxide that has been generated by your cells as part of their normal function of metabolism and put out into your blood. As the blood passes through those capillaries next to the alveoli, the carbon dioxide is diffused back across from the blood to the lungs. You then breathe it out as you exhale.

Energy Systems

When you run, irrespective of the intensity that you are running at, you are utilising three primary energy systems:

1. Your aerobic system.
2. Your lactate system, also known as your anaerobic system.
3. Your alactic system, sometimes known as your phosphocreatine system.

Your aerobic system uses oxygen and both glucose and fat to help your body’s muscles and other tissues keep you running. It becomes the dominant energy system when you are on your easy runs and the intensity is below your lactate threshold 1 level. The other two systems are still active, but much less so.

As your intensity increases, you begin to transition across your energy systems and your lactate system becomes more active. This system still uses glucose as fuel, but doesn’t use oxygen and doesn’t really use fat (it can but it’s so minor that common teaching is that it doesn’t). This transition zone that includes some upper aerobic system activity and some lactate system activity is where you are usually operating in when you are running a hard 5k and 10k, and in certain places during longer distances as the intensity increases at times. The skill with this transition zone, between lactate threshold 1 and lactate threshold 2 is balancing your effort so that you almost ‘surf the wave’ by keeping enough oxygen and fuel being supplied to your working muscles and the waste products of the cells from energy creation (lactate, CO2 etc) being removed and cleared (or reused in the case of lactate), with pushing hard enough to get the performance you want. This is a zone I like to refer to as the speed endurance zone.

The harder you push, the closer you get to lactate threshold 2 and the less oxygen is available for your working muscles. The waste products from the cells also can’t be cleared efficiently because your blood cannot move around your body fast enough. This basically puts you on a timer before your cells are unable to function as needed. For well trained runners, this timer is around 3 to 5 minutes. For the rest of us it can be a lot less.

For completeness, the energy system that is dominant when you are at your highest level of intensity (think of a 10 second all out, max intensity sprint) is your alactic system. This doesn’t need oxygen, glucose or fat, instead relying on an internal energy source. However, this internal energy source is like a flashbang in that it burns very brightly, but only for a few seconds. Typically, your alactic system can only function well for between 5 to 10 seconds depending on how well trained you are. If you are ever at a running track and watch sprinters training high intensity short sprints, you’ll notice that they take very long recoveries (sometimes 5+ minutes) between each rep. This is to allow that alactic system to fully recharge, otherwise the sprint will be done in the lactate system or even in the threshold or aerobic systems if the recovery is very short. While you will use your alactic system in your normal running (think of finish line sprints, overtaking etc), and you do need to train it, you won’t need to put as much emphasis on it as the other two systems.

So how does all of this relate to breathing? Let’s find out…

Running, O2 and CO2

As you’ve just learned, the higher the intensity of your running, the less efficient your system becomes at both getting oxygen to your body’s cells, and at removing the waste products such as carbon dioxide from your cells. In both cases, this will force you to slow down at the very least.

But for many runners this leads to panic and breathing difficulties. As you discovered in article 3, carbon dioxide is the chemical trigger for you to take a breath in. Because carbon dioxide builds up as your intensity increases, the trigger to breathe can get very strong very quickly. This can cause that feeling of panic and you start to gasp. Unfortunately, this more often than not will result in either hyperventilation or paradoxical breathing (where your breathing muscles are doing the opposite of what they should be). Neither situation is good and can result in your predictive brain learning that running hard is unsafe.

Now, you may think that taking in larger breaths, particularly through your mouth, will lead to more oxygen getting into your blood and out to your cells. Unfortunately it doesn’t really work like that. We’ll look at this more in the next article which is on nose breathing, but for now you just need to know that due to things like respiratory rate, dead space and a simple formula, more air and quicker breaths don’t equal more oxygen. For that, you need to learn to breathe more efficiently to get more oxygen exchanged, and to not react when you get those triggers to breathe in the way that you are currently doing.

One of the first steps of doing that is to increase your tolerance, or reduce your sensitivity, to the build up of carbon dioxide as the intensity of your running increases. In turn, this reduces the panic response, and while you may still have to slow down a bit, it is more controlled and you’ll be able to hold a higher intensity for longer. This is the hypercapnia training that I mentioned in article 3, and is all about training your system to tolerate lower levels of oxygen (hypoxia) and higher levels of carbon dioxide. To begin with this, let’s start with a simple exercise (this is the one from the ebook):

1. Take a slow breath in through your nose for a 4-count.
2. Exhale slowly for a 4-count and hold for a 4-count.
3. You may start to feel a small amount of air hunger near the end of the breath hold, but don’t worry if not.
4. Progress to holding that out-breath for a count of 5 then 6 then 7 to start to experience the feeling of air hunger. You may find it induces panic, in which case just dial it back.

There are many ways of progressing this exercise, and also several variations that I often use with my clients. The first one I start with is to do rounds of these breath holds like this:

1. Take a normal breath in through your nose and then a normal breath out through your nose and hold your nose.
2. Count to 5 and then take a normal breath in through your nose, trying not to gasp the air in, and then out through your nose.
3. Take another normal breath in through your nose and then a normal breath out through your nose and hold your nose.
4. Again, count to 5 and then take a normal breath in through your nose, trying not to gasp the air in, and then out through your nose.
5. Repeat this for a total of 5 breath holds.
6. Continue breathing through your nose for another 30 seconds to 1 minute depending on how much recovery you feel you need.
7. Complete three sets of the above.
8. Aim to do this several times a day for the next week until it becomes easy to do. Then reduce the two breaths between breath holds to just one breath.

With continued practice of all the exercises you’ve learned on the ebook and articles, you will be well on your way to reaping the rewards of more efficient and functional breathing.

In the next article you’ll learn about nose breathing and why it’s important in your life in general, but also why it’s vital to start building it into some of your running.

The post The Biochemistry Of Breathing appeared first on RunTeach.

You can expand on this exercise with a variation that encourages the mindfulness to be even more deliberate. It’s a version of box breathing but the inhale, hold, exhale, hold are not all the same length of time: more like rectangular breathing, but I don’t think that’s a thing… 

Anyway, you can progress the holds so they are longer, but I find most people like to start with shorter breath holds and go from there. So, let’s have a look at the exercise and then we can look at other aspects of how the brain is influenced by your breathing but also how the brain itself can impact upon your breathing.

Paced Breathing Practice

1. Find a comfortable position, seated or standing.
2. Breathe in for a 4-count through your nose and hold for 1 second.
3. Exhale slowly for a count of 4 and hold for 1 second.
4. Continue the pattern of in for 4, hold for 1, out for 4, hold for 1.
5. Aim to evenly pace your breathing across the 4-count of both the inhale and exhale.
6. Repeat for 1 to 2 minutes, allowing yourself to relax into the exercise and avoid becoming tense or trying too hard.
7. When you are ready, you can progress in three different ways:
   1. Extend the holds so you end up with in for 4, hold for 4, out for 4, hold for 4.
   2. Extend the inhale and exhale counts to 5, eventually progressing the holds to a 5-count.
   3. Change the inhale to a 4-count with a 1 second hold and the exhale to a 6-count with a 1 second hold.

Each of these progressions is designed to encourage even paced breathing and build your confidence with slightly longer breath holds.

Up to a point, this and similar exercises help to calm your sympathetic nervous system and are great for bringing you into the current moment. However, if you have some form of breathing challenge including dysfunctional breathing, holding your breath or even trying to pace your breathing for any length of time actually becomes a threat to your brain and this can cause panic and anxiety.

You may notice this panic feeling when you are out for a run and are pushing hard. All of a sudden you feel you can’t breathe properly and you start to panic. This is called paradoxical breathing and is where your breathing muscles are now operating almost in reverse to your inhalations and exhalations: essentially, your chest expands on the out breath instead of the in breath. Learning how to pace your breathing with the exercise above is a great start, but there is often more to it than that.

The brain with its nerves and blood supply

The Brain’s Influence On Your Breathing

Your brain is a prediction engine, using your past experiences, knowledge and learnings to predict what’s going to happen in any given moment. Actually, it makes its predictions and actually puts actions into motion a fraction of a second before you are even consciously aware of it. These predictions involve how you react to what’s going on around and inside you, all of the time. Your thoughts, actions, movements and feelings (including emotions) are all shaped by these predictions. And all of those things feed back in to help shape your predictions for future reference.

Ultimately, your brain’s number one job is your survival.

It uses your current predictive models to do what it can to ensure that you get through every day without dying or being fatally injured. Sometimes this means it needs to take drastic action like producing an experience of pain, panic, anxiety, fatigue and other outcomes we would interpret as being undesirable. These are simply your brain’s way of reducing or avoiding what it perceives to be a threatening situation, even if it has got it wrong – this does happen which often leads to chronic pain conditions and other health challenges, both mental and with physical manifestations.

So, one of the reasons I always begin teaching efficient and functional breathing by becoming aware of the muscles of breathing and mobilising the rib cage, is that it helps to build more helpful predictive models around how you breathe in different situations. If your brain knows how to move your rib cage in a way that can create more space for your lungs to do their job, and knows that you have good activation and relaxation of the muscles involved, it is more likely to trust that you’ll be safe. In terms of your breathing, this means your brain is less likely to go into a panic state because it knows how to breathe under load.

Brain-safety is super important and part of the reason that you may get panicky when you do longer breath holds, particularly if you’ve just exhaled, is because your brain feels unsafe and doesn’t know when more oxygen will be available: no oxygen = eventual death.

But this prediction isn’t just based on a mechanical trigger, although one of those does exist. Actually, it’s not a mechanical trigger, it’s a chemical one. The longer you hold your breath, the more you will get a build up of carbon dioxide, and this happens more quickly after an exhale breath hold and even more so if you are moving. High levels of carbon dioxide build up in the blood is a condition known as hypercapnia, and this usually triggers your diaphragm to take an in-breath. If you try holding your breath for a long time you will feel your diaphragm starting to activate and it’s very hard to to override, if not impossible.

While hypercapnia training is a very important part of how I teach more efficient and functional breathing, especially for runners and active people, it’s introduced gradually and I always take into account the other reasons that can bring on panic during breath holds.

Remember that the brain is a prediction engine? Well, your predictive models are being shaped continually: every experience in every moment is influencing your predictive models and therefore helping to create how you react in future moments. Perhaps at some point in your life you had an unpleasant or unhelpful experience related to being out of breath. Maybe it wasn’t even you and it was a family member, friend or even just someone you observed. It could even have been a movie you watched, an article you read, something someone told you or something you experienced, read or watched online. All of these things shape your predictive models, and if there was something in there somewhere that caused your brain to believe, rightly or wrongly, that being without oxygen even for a short time would be unsafe, then it’s not going to let you do that.

As soon as you get into a situation where the carbon dioxide build up is even remotely triggering a lack of oxygen, your brain predicts the worst and literally hits the panic button. If you are out running at the time, this may result in you needing to stop or slow right down and reset your breathing. 

And to add to the complexity, because your brain is predicting just ahead of your conscious awareness, other situations where your brain feels unsafe can trigger the same reaction before you have any conscious control. For example, have you ever felt fear and your breathing has gone into a panic state as a result? How about embarrassment triggering the same thing? All of these things can be perceived as threatening and your brain is using panic breathing to warn you to change something – most often it’s to warn you to get out of the threatening situation.

Phew! So, the difference between how I teach people to improve their breathing and the way most other courses and instructors teach it, is that I also take into account the neuromechanics (or neuro-biomechanics) and the neurology and the role that your brain plays in your breathing. I teach extra exercises that may appear to have nothing to do with breathing (such as tongue exercises) but help your brain to feel safe by stimulating specific nerves and neural and spinal pathways. By first teaching you how to move well and use your breathing muscles, you are creating improved brain-body mapping and building more helpful predictive models. These in turn help your brain to feel safe so it can get on with learning how to breathe well. This can often be a challenging concept, but it’s firmly rooted in science and has proven to be highly effective.

Conclusion

This article is certainly more in-depth than the first two, but the role of your brain and nervous system in your breathing is so important it requires you to appreciate the importance of working with them in order to quickly and efficiently improve your breathing. Just spending time on standard breathing exercises doesn’t cut it in my book. It will usually take a long time to get good at breathing and more often than not you’ll give up before you see the real results and benefits.

So, you can influence your brain by how you breathe: efficient and functional breathing helps your brain feel safe and can reduce panic and anxiety, and also helps to improve your performance and overall well being. All of this helps to build more helpful predictive models for future reference.

And, your brain can also directly impact how you breathe and the quality of your breathing – I’m sure you’ve spotted the circular feedforward loop in there where one feeds into the other. 

To achieve efficient and functional breathing when running, and in the rest of your life, you need to help your brain feel safe and this involves training it in complementary ways and providing it with the most helpful predictive models you can.

In the next article we’ll look in more detail at carbon dioxide and the biochemistry of breathing.

You can find the first supporting article on the Muscles of Inhalation here.

As a reminder, we look at the biomechanics of breathing, we really need to be looking at:

1. The muscles of inhalation
2. The muscles of exhalation
3. The skeletal components such as your rib cage
4. The integration and control of all of the above, and you ability to effectively use them under different conditions

This article takes a brief look at the muscles of exhalation.

Exhalation

Exhalation, or breathing out, involves a number of muscles including:

Some of the muscles of exhalation

As with inhalation, exhalation involves a lot of muscles that need to contract to help change the size and shape of the breathing cylinder. As important though, and often overlooked, is the ability of all of these muscles to relax.

For the rib cage to expand up and outwards during inhalation, the muscles of exhalation need to be in a relaxed state to allow this to happen. Equally, for your rib cage to come down and in, the muscles of inhalation need to relax.

It is this coordination of tense/release that allows fluid movement of the breathing cylinder, helping to form the foundation of efficient and functional breathing. It is always my starting point when working on improving someone’s breathing, as even if they don’t get some of the other techniques right away, I know they will have good quality movement in this area.

High quality movement is amazing for reducing the overall threat that your brain experiences in every moment of every day. And given that you can only handle a certain amount of threat before you begin to experience undesirable outputs such as pain, panic, anxiety, fatigue and a whole host of other stuff, deliberately practising high quality movement throughout your body is an essential element of achieving and maintaining a high level of health and wellbeing.

To experience the muscles of exhalation, you can use the same exercise from the first article (see below) as it is a fantastic awareness exercise. Just shift your focus to the exhalation aspect, making relaxation a deliberate action. This can seem a bit strange at first as focussing internally can result in more tension in your muscles. One way to get around this is to close your eyes and imagine the contraction of some of the muscles of exhalation while also allowing a smooth relaxation to occur. This takes a bit of practice but is worth doing. 

This is also a fantastic mindfulness exercise that can help calm and settle you.

1. Stand or sit with your back straight, shoulders relaxed.
2. You may find that lying on your back can be a useful position for this version of the exercise.
3. Place your hands around the base of your ribs.
4. Inhale slowly through your nose.
5. Exhale slowly, feeling your ribs come down and in, reducing the size and shape of your breathing cylinder. 
6. Repeat the exercise a number of times to get a good idea of how well you are activating and relaxing the muscles that help your rib cage to change shape and position.
7. Do you notice a difference between your right side and your left?

Now change the position of your hands so that they are half way up your rib cage and repeat the deep, slow exhalations. Do you feel your rib cage moving at this level?

Now move your hands to your upper ribs, just below your collar bones. Repeat the inhalations and observe how well your rib cage is moving.

What’s Next?

Take some time to practise both versions of the awareness exercise: inhalation and exhalation. Doing this daily is a great way to add some mindfulness while at the same time bringing in body awareness. It’s absolutely fine if you can’t move smoothly at the moment as it takes some deliberate practice and good coordination between relaxation and contraction.

And this coordination skill is the subject of the next article as we look at the role of neuromechanics and your brain in helping you to breathe better and more efficiently.

You may have already learned that your diaphragm is your main breathing muscle, and that to breathe efficiently you need a strong diaphragm. 

Rib cage and diaphragm.

This is absolutely true, but it isn’t the whole truth. While it is important to strengthen your diaphragm, you also need to look at how you are using it as well as how you are using the other muscles of respiration. In addition, how mobile your rib cage is can have a dramatic impact on how well you breathe, particularly under load such as running hard or for a long time.

So when we look at the biomechanics of breathing, we really need to be looking at:

1. The muscles of inhalation
2. The muscles of exhalation
3. The skeletal components such as your rib cage
4. The integration and control of all of the above, and you ability to effectively use them under different conditions

Inhalation

Inhalation, or breathing in, involves several key muscles such as:

You can see from this table that there is a lot involved. You can also start to see why putting your focus on just the diaphragm isn’t going to cut it – you need to activate and use your entire ‘breathing cylinder’ as it allows more space for the lungs if the rib cage is lifted up and out in all directions.

When I work with both runners and non-runners on their breathing, they often struggle to activate some of the muscles above. If they can already activate some of them, they tend to be better on one side than the other. They almost always need to spend a bit of time learning how to create the brain-body connections so that they can begin to mobilise the rib cage and create some extra room.

One of the first exercises we do is an awareness exercise so you can determine how you are currently using your rib cage:

1. Stand or sit with your back straight, shoulders relaxed.
2. Place your hands around the base of your ribs.
3. Inhale slowly through your nose. Ideally, you feel your ribs expand out towards the front and sides. 
4. Repeat the exercise a number of times to get a good idea of how well you are activating the muscles that help your rib cage to expand.
5. Do you notice a difference between your right side and your left?

Now change the position of your hands so that they are half way up your rib cage and repeat the deep, slow inhalations. Do you feel your rib cage moving at this level?

Now move your hands to your upper ribs, just below your collar bones. Repeat the inhalations and observe how well your rib cage is moving.

If you can’t activate and move your ribs smoothly and pretty much symmetrically, then you have some practice to do. One way to do this is to spend 5 minutes or so a couple of times a day repeating the exercise above, putting your focus on activating the muscles involved.

The other way involves specifically activating the individual muscles using a technique called assisted contractile mapping, or tense/release. Unfortunately the explanation for this is beyond the scope of this article, but it is included in my breathing course for runners which will be launched very soon.

Have a go at rib cage expansion exercise above and in the next article we’ll look at the muscles of exhalation.
