Respirar por la nariz o por la boca al correr: qué cambia según la intensidad del ejercicio y qué muestran los estudios

Recent studies examine how runners breathe through the nose versus the mouth depending on the intensity of their exercise. When running begins at a slower pace, air typically enters through the nose without requiring a conscious decision from the runner.

As the running pace accelerates, the physiological demand for air increases, leading the mouth to incorporate into the breathing process gradually.
