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

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.
