The part of breathing we generally think about is all to do with enough oxygen getting to the right places fast enough for us to do what we want to. Our bodies are pretty good at this in the absence of any serious health issues.
But you probably don’t realise our breathing also has a major impact on our overall posture and movement and our nervous system, particularly that crucial balance we need between our ‘ready for action’ stress response versus rest, recover and repair.
Breathing in sport is becoming hot news! We put emphasis on strength training especially when it comes to legs, but does anyone really target the breathing muscles?
The case for breathing training
In the last couple of decades it was discovered that like any other muscles our breathing muscles fatigue, swimming being the biggest culprit here. When they fatigue, there then follows a literal blood steal reflex shifting blood from the leg/arms to the breathing muscles. This happens because the brain reckons it’s more important to keep breathing than run faster!
So what can you do? Specific inspiratory muscle training (weight lifting for the diaphragm) will:
- delay the blood steal reflex;
- reduce our sense of effort (our heads are a huge barrier to performance);
- hasten the removal of lactic acid;
- speed up your recovery.
Breathing in triathlon
If that’s not a good enough reason then consider all the challenges put on your breathing muscles during triathlon.
Swimming – Our breathing muscles have to overcome hydrostatic pressure and need to achieve rapid inhales to maintain buoyancy and propulsion.
Running – we are permanently unstable when we run and breathing muscles have to both pull air in, push it out and keep the pelvis stable.
Cycling – horrible position for breathing! The breathing muscles need all the help they can get to overcome the restrictions imposed by crouching and again stabilising the pelvis to maximise efficient pedalling.
Breathing in recovery
Recovery is not talked about nearly enough in coaching yet the ability to bring ourselves back to baseline calm (think heart rate, breathing rate, blood pressure, relaxation, digestion, inflammation, immune response) is crucial to our ability to recover from our last race/training session and the success of our next one.
Outside of training/racing is another crucial area where sub-optimal breathing can play havoc. Recovery, otherwise known as all the hours we spend at work and home, awake and asleep is where breathing plays a crucial role.
You lot are by nature pretty busy and pretty driven! This is great for being out there on the run/swim etc but for adequate rest and recovery we need to bring our nervous system back to calm.
Breathing is a powerful regulator of our autonomic nervous system – that balance between emergency response (heart rate, breathing rate, blood pressure up, muscles tense) and our rest, digest, repair, immune boosting state. Nearly all the athletes I see have a few things in common…
- They over-breathe at rest. This lowers the level of carbon dioxide in the body resulting in poor oxygen delivery, muscle spasms/tension, and airway and blood flow restrictions.
- They breathe into the upper chest. This results in fatigue of the accessory muscles (neck/shoulders i.e. muscles we need for effort) and a whipping up of the stress response (see above – not great for recovery).
- They are ab suckers. Your diaphragm is your prime muscle for breathing and core strength to name just two of it’s functions. It cannot work effectively against an abdominal corset.
- They frequently feel the need for sighs and often mouth breathe – this is hyperventilating, (see point 1).
Have a look at your own breathing
- Do you nose breathe 100% outside of hard effort?
- Do you have exercise induced asthma/ chest tightness/wheeze/tightening in the throat?
- Do you sigh/yawn a lot?
- Does your chest or belly move as you inhale/exhale at rest?
