Inspiratory muscle fatigue following running to volitional fatigue: The influence of baseline strength McConnell, A. K., Caine, M. P, & Sharpe, G. R. (1997), International Journal of Sports Medicine, 18, 169-173.

Respiratory muscle fatigue has been demonstrated following short-term exercise to volitional fatigue as well as following prolonged sub-maximal exercise.

Moderately trained men (N = 24) were examined to determine if inspiratory muscle strength influences fatigability. Inspiratory muscle strength was measured using a Mouth Pressure Meter before and after an incremental, multi-stage shuttle run to volitional fatigue.
