Ah, breathing, a normal autonomic function we subconsciously and consciously do every day. While breathing is something we may not think about on a day to day, things such as allergies or pollen can easily plug up our nose and making breathing more difficult. With evolution and changes in the types of foods we ate as we grew, our bone structures have changed making our nasal cavity much smaller and therefore, much harder to breathe through. Although this is true, we get 20% more oxygen through our nose than mouth, yet still, 50% of people breathe through their mouth .
Nasal breathing increases circulation, delivers oxygen to cells, aids in immune function, weight control, mood, and sexual function. The benefits you can receive from nasal breathing go even further beyond just this. Lowering your blood pressure, heart rate, and improving your tolerance to exercise are just a few more of the benefits of nasal breathing .
Have you ever thought about how you breathe when you work out? Or, not until you pushed your intensity and then found yourself out of breath? Do you ever find yourself out of breath while trying to run? This can mean your pace is a little too fast or you are not maximizing your breathing effort while running, due to improper technique. So what is the ‘proper’ technique? Let’s explore 3 tips to optimize your diaphragm function and improve your running efficiency.
1) Practice Deep 360 Breathing:
First, we must figure out how to control our breath and how to breathe. To explore this, start by getting in a comfortable place on your back and placing one hand on your chest and one on your belly. Breathe normally, and see what happens. Does your top hand rise and fall or your bottom hand? What about a combination?
Our diaphragm is a muscle that lives inside our trunk and assists in postural stability during sudden voluntary movements of the limbs. It creates and regulates pressure influencing both the pelvic floor and abdominal muscles and allows our lungs to inflate as we breathe in to help force air out as we exhale .
During an inhalation (breath in), our diaphragm descends into our abdominal cavity, and as we exhale (breath out) our diaphragm comes up. The pelvic floor systemically works together with the diaphragm and surrounding muscles responding to the change in intra-abdominal pressure. Therefore, the pelvic floor can affect diaphragm motion and pulmonary function . This is important to understand, especially postpartum since the baby has squished the diaphragm up and the diaphragm has lost its ability to fully expand temporarily.
Practice 360 breathing, by using your hands as targets for you to push air into. You should be able to expand through your belly, both sides, and back to practice using the full functionality of the diaphragm.
All together now,
Breathe in through your nose (fill belly, sides, and back). Breathe out allow the air to slowly leave your nose.
2) Nose vs. Mouth Breathing
Breathing through your nose could cut the total exertion of an exercise in half and offer tremendous gains in endurance! But what if you are having difficulty doing this?
Start by practicing nasal breathing during your 360 breathing exercise. Once you have mastered that, then take your breathing on the road. Start with focusing on breathing through your nose during the first 3 minutes and the last 3 minutes of your run. At first, you may notice this is very challenging, and you may feel like you can not get in enough air, but fear not, it will become easier and this is completely normal!
It is also important to be mindful of your posture while running, as this could affect your breathing. The zone of apposition or ZOA is the alignment of your rib cage, diaphragm, and abdominals for optimal function. This helps to maintain the dome-like shape of the diaphragm so it can contract and relax appropriately. If our posture is poor during a run, this can influence its function and cause shallow breathing patterns . Stand up tall and avoid the 'computer slouch' posture, now lean into it and hit the trails.
If you feel like you are breathing through your neck and shoulders, this is something that you can improve by doing your 360 breathing exercises! It is not odd that you may breathe like this since we have accessory muscles to breathing along the sides of our neck, but if you continually breathe this way it could lead to neck, rib, or shoulder dysfunction to name a few.
Once you have found your flow with breathing at rest and you have mastered nasal breathing during your first 3 minutes of your run and last 3 minutes, you are ready for the next step. Slowly increase the nasal breathing so you can breathe in and out through your nose throughout your entire run. If you choose to breathe out through your mouth, that is okay, as long as your mouth and jaw are relaxed. Using the muscles in your jaw or mouth by clenching or pushing air out can cause overall energy depletion that we want to save for our legs!
3) Matching your Breath and Cadence
The final challenge is to try to match your new breathing pattern to your running cadence (steps)!
To practice this, start running at a slow to moderate pace. Count how many steps it takes for you to inhale and exhale. A step is when your foot contacts the ground on one side only. This is an individualized number to YOU, therefore; there is no magic number here. On runs, I will often have 2 inhales to one exhale and therefore 4 steps to 1 step ratio of breathing. It works for me, and I can appropriately belly breathe without using my shoulders and neck to help.
Depending on your speed and intensity of your run, you will eventually get so good at this that it will be like shifting gears on a bicycle. The quicker you run, the number of steps per inhale and exhale may decrease. Make that connection and find a rhythm that works for you and suits your purpose.
Take time to practice and adjust your breathing. I usually educate all of my clients about breathing on their first visit, as I see the effects it has on pain levels and stress. Physiologically, our parasympathetic system is influenced by breathing inducing a “rest and digest” response in our bodies. Taking control of your breathing and how you do so you can make lasting effects on your quality of life and enhance your athletic performance once done correctly!
