| Chest examination revealed fine late inspiratory crackles with otherwise normal breath sounds. |
| This could make the inspiratory muscles vulnerable to the development of muscle fatigue. |
| The increase in the utilization of inspiratory and expiratory reserve volumes with exercise facilitates airway clearance. |
| There are no recent published reference ranges available for inspiratory or expiratory airway resistance. |
| Pulmonary function, maximal inspiratory and expiratory pressures, quadriceps force, handgrip force, and maximal exercise capacity were assessed. |
| Auscultation of the lungs revealed inspiratory crackles in the lower lung zones. |
