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.

Getting confused?

With up to 80% of runners being struck down by a running related injury in every 12 month period, it’s about time you took action to reduce your own injury risk.

All over the Internet you can find many ways to do this from Yoga for runners, a million different ways to stretch, mobility for runners, and of course everyone’s favourite, strength for runners.

Do you really have to do all of these? If not, which is best? How can you decide where to invest your time and money? Do you even need to invest any money because there are literally thousands of free posts and videos in all of the categories I mention above. Where do you start?

Stripping it back

Let me help by peeling it right back to bare bones – well, hopefully not literally, but you get my point. Let’s strip this thing down!

There is only one reason you get injured – your body’s tissues cannot handle the forces being applied to them. It actually is as simple as that… and as complicated as that!

Let me elaborate with a little more detail. Your physical tissues don’t know about miles or kilometres. They don’t know about trail runs, road runs or track sessions. They don’t even know about running. You could be swimming, cycling, rock climbing, digging out your allotment, skiing or rock climbing. All your physical tissues know about is mechanical force.

Mechanical force is simply the load that’s applied to your tissues (bone, muscle, connective tissue, skin, etc) at any given time. They can either withstand the force, or they can’t. If they can’t, they fail and injury occurs – simple.

When looking at mechanical force, we need to look at the three primary elements:

1. Intensity
2. Frequency
3. Duration

Intensity

Intensity is the amount of force; it’s the level of loading or impact. For example, if you whack yourself on the thumb with a hammer (don’t do this by the way), there is a higher intensity than if you poke your thumb with your finger (unless you are mega strong of course).

When running, the level of intensity tends to be influenced by how efficient a runner you are, your bodyweight (although you’d be surprised on this one), the speed you are running at, and the surface you are running on including the incline/decline, your ability to control how you land and your reflexive stability (joint stability).

Frequency

Frequency is the number of times the force is applied in any given period.

When running, you can look at frequency at both a micro and macro level. At a micro level, frequency is the number of steps you take in a minute. This is commonly known as your cadence, and most running watches will give you this number. Contrary to popular belief, there is no ideal cadence.

It was commonly thought that 180 beats per minute (or steps per minute to be more accurate) was the ideal, but this was misinterpreted from some track sessions of a very few elite athletes quite a few years ago. These days, most professionals and coaches accept that we find our own cadence to a certain extent, but under certain circumstances there is a range that appears to be more efficient in terms of performance and injury prevention. 

Personally, I like to help people achieve between 176 spm and 186 spm as I’ve found that to be a good range to encourage efficient form while also encouraging good performance. Current research isn’t conclusive in terms of injury prevention and cadence, but this is often because the research itself is flawed. There is some evidence that if runners with a slower cadence, who are also experiencing pain in certain areas, increase their cadence they can reduce their pain. But higher quality research is required to provide us with the data we need in order to make better decisions around cadence and injury risk.

Anyway, back to the point. If you have a cadence of 176 spm, your tissues are exposed to the forces of running 176 times per minute. You may think then, that a lower cadence is good, but it’s a bit more complex than that as with a lower cadence your feet are on the ground for longer – see Duration for more on this. As a side note, this is why some evidence points to a higher cadence – feet are on the ground for less time.

When viewed at a macro level, frequency becomes about the number of runs per week, month, year etc. Not paying attention to this is a leading cause of overtraining that in turn can result in your tissues not being able to handle the forces involved.

Duration

Duration is over how long the forces are being applied – it’s a period of time. Like Frequency, duration can be viewed at both a micro and macro level.

At a micro level we need to consider how long your feet are on the ground with every step, known as ground contact time and is measured in milliseconds. Most efficient runners have a ground contact time of 220 ms or less, whereas most recreational runners tend to trend from 250 ms to 350 ms or higher. Now, this is still a fraction of a second, but that small difference in time exposes your tissues to the forces of running for that little bit longer, and it makes a difference to both injury risk and performance.

At a macro level, you can view duration as the time you are out on each run, and your overall time running in a week, month, year etc. 

Why tissue fails

As you’ve just learned, mechanical force is applied to your tissues every time you go for a run. In fact, it’s applied all of the time in every moment of your life. It is present in an almost infinite combination of the three elements mentioned above, and how well your tissues are adapted to each combination determines whether they handle it or fail – or breach the threshold for your nervous system to be happy, and this then results in niggles and pain.

To reduce your injury risk you need to train your tissues to adapt to these forces – again, it’s as simple as that. There are ways to reduce the forces through improved efficiency (elements of technique for example), but there will always be forces your tissues need to handle.

To adapt, your tissues need two critical components. If these aren’t present, your injury risk  increases. These are:

1. Load: you need to overload your tissues for them to adapt
   
   
2. Recovery: I always say that “the magic happens in the recovery”. During recovery, your tissues are rebuilding and reorganising so they can better handle the same overload of forces the next time they are exposed to them

It is crucial to understand though, that:

1. If the overload is too much (any excessive combination of the elements of mechanical force), your injury risk increases
   
   
2. If the overload is too little, no or minimal adaptation is forced

The skill is finding the balance between these two, combined with appropriate recovery, and in line with your goals.

How to use this info

Now you have a simple overview of why injuries occur, let’s have a brief look at how you can use this knowledge to reduce your own injury risk. Again, at a foundation level there are some easy things you can do:

1. Frequency: This is probably one of the easiest areas to address, although not all runners actually want to take action here. When looking at frequency you need to look beyond just running. You need to look at what else you are doing in your life that’s exposing your tissues to overload. Remember, your tissues don’t have any concept of running, going to the gym or any other activity – all they know is mechanical force.
   
   Increasing the number of runs per week increases your frequency of loading while also reducing potential recovery time.
   
   Reviewing your overall loading activity, both running and non-running, and the amount and quality of your recovery can highlight areas where you are doing too much and not giving yourself appropriate time to adapt.
   
   
2. Duration: Another area that’s relatively easy to review if you are allowing your tissues to adapt or not. Look at the length of your runs and the length of your recovery periods. Similar to above, the longer your runs, the less time you have for recovery and the more you expose your tissues to the mechanical forces of running.

It’s very common when building up to longer distance events that we increase our mileage. While your body has no physical sense of distance, increasing your mileage will generally result in an increase in the duration of your runs. This exposes your tissues to potential overloading for more time before they get some recovery.

Paying attention to any sudden increases, as well as looking at your overall duration of both running and non-running loading activities can help you identify if you are allowing your tissues to adapt or gradually wearing them down.

I have deliberately missed out Intensity here as it’s more complex to address. This is where we need to look at efficiency which brings with it a whole bunch of skills training and skill endurance – my main passion and the focus of most of what I teach.

For now, making sure you are reviewing both Frequency and Duration will help you to reduce your injury risk and improve your overall running performance.
