Breathing performance research

Breathing interventions can help if they reduce wasted effort and improve tolerance at high work rates.

  • • Most gains come from fitness, but breathing training can be a useful accessory.
  • • If it causes dizziness or panic, stop; do not push through.
  • • Use simple protocols and measure whether it changes your pacing/RPE.
