Cycling Performance Club: An exercise in intervention evaluation: Does nasal breathing improve performance? - a podcast by Damian Ruse
from 2021-09-24T20:00
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?
