Evaluation of a training intervention: Does nasal breathing improve performance?

Damian Ruse Cyrus Monk Dr. Jason Boynton

Show Notes

We take a dive into the nasal passage (pun intended?) and look at whether there are performance gains that can be obtained by employing nose breathing techniques. This ended up leading to a discussion around how we can evaluate training interventions and make decisions on whether they’re worth implementing for ourselves and our athletes.

Episode Timestamps:
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?
