Summary

Voluntarily increasing breathing rate (hyperventilation) during exercise significantly reduced exercise duration in healthy subjects. This suggests respiratory muscle work strongly influences exercise performance and fatigue.

Area of Science:

  • Exercise Physiology
  • Respiratory Physiology

Background:

  • Respiratory muscle work increases with exercise intensity.
  • The impact of volitional hyperventilation on exercise performance is not fully understood.

Purpose of the Study:

  • To investigate the effect of volitional hyperventilation on exercise duration during ramp exercise to exhaustion.

Main Methods:

  • Nine healthy subjects performed ramp exercise tests to exhaustion.
  • Subjects volitionally hyperventilated at 20 L x min(-1) above their baseline during a subsequent test.
  • Pulmonary function tests (maximum voluntary ventilation, forced vital capacity) were conducted at various exercise intensities.

Main Results:

  • Exercise duration was significantly reduced (p < 0.002) with additional hyperventilation.

  • Pulmonary flow rates were enhanced at exercise intensities above the lactate threshold, during exhaustion, and recovery.
  • Despite enhanced flow rates, increased respiratory muscle work diminished exercise performance.

    • Conclusions:

    • Volitional hyperventilation, increasing respiratory muscle work, diminishes exercise performance.
    • Respiratory muscle work is a key factor in exercise fatigue during ramp exercise in healthy individuals.
