We take a dive into the nasal passage and look at whether there are performance gains to be obtained through nose breathing. This leads to a discussion around how we evaluate interventions and make decisions on whether they’re worth implementing for ourselves and our athletes.2:30 How do we normally breathe during exercise?8:25 What are the claimed benefits of nose breathing over mouth breathing?9:15 Are we getting too much oxygen?21:15 What do the studies show?29:25 What level of evidence do you require to apply an intervention?38:30 If it’s free and easy, should you try it anyway?46:55 How much does air intake affect endurance performance?55:10 But the nose is a filter and humidifier, does that help?This episode’s panel:Jason Boynton, Ph.D.boyntoncoaching.comDamian Rusesemiprocycling.comCyrus Monkcyclistscientist.comInstagram: @cyclingperformanceclubFacebook: @cyclingperformanceclubTwitter: @cyclingclubpodReferences:Oxygen - Haemoglobin Dissociation Curve Explainerhttps://www.youtube.com/watch?v=BYGPkRFvzOc&ab_channel=ArmandoHasudunganOronasal Distribution of Ventilation at Different Ageshttps://www.tandfonline.com/doi/abs/10.1080/00039899709602874The switching point from nasal to oronasal breathinghttps://www.sciencedirect.com/science/article/pii/0034568780901048Effects of Nasal or Oral Breathing on Anaerobic Power Output and Metabolic Responseshttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC5466403/ Effect of Nasal Versus Oral Breathing on Vo2max and Physiological Economy in Recreational Runners Following an Extended Period Spent Using Nasally Restricted Breathinghttps://www.journals.aiac.org.au/index.php/IJKSS/article/view/4400
