Summary

Different breathing assemblies did not significantly alter maximal exercise responses in runners. However, breathing mechanics at the ventilatory threshold were affected by the breathing apparatus used.

Area of Science:

  • Exercise Physiology
  • Sports Science
  • Respiratory Physiology

Background:

  • Breathing assemblies are used in exercise testing to measure metabolic and ventilatory responses.
  • Different breathing apparatus designs may influence respiratory mechanics and physiological responses during exertion.

Purpose of the Study:

  • To compare ventilatory and metabolic responses during maximal exercise using three different breathing assemblies: mouthpiece/noseclip (BV), mouth/face mask (MM), and facemask (FM).
  • To investigate the impact of breathing assemblies on key exercise physiology metrics at maximal effort and ventilatory threshold.

Main Methods:

  • Ten male runners performed three randomized maximal treadmill tests, each with a different breathing assembly.
  • Metabolic (VO2, RER), ventilatory (VE, VT, f, PF), heart rate (HR), and rating of perceived exertion (RPE) were recorded.

Main Results:

  • No significant differences were observed in maximal exercise performance (run time, HRmax, RER, RPE) across the three breathing assemblies.
  • Maximal VO2, VE, VT, and f did not differ significantly between the breathing assemblies.
  • At the ventilatory threshold (TVENT), VO2, VE, and f were similar, but peak flow (PF) was higher with BV, and tidal volume (VT) was higher with BV compared to MM and FM.

Conclusions:

  • Breathing assembly type does not significantly affect maximal ventilatory and metabolic responses during running.
  • Alterations in ventilatory mechanics, specifically peak flow and tidal volume, may occur at the ventilatory threshold depending on the breathing assembly used.
