Text: For the sham and active impedance threshold device groups, respectively, the mean + / - SD imposed power of breathing values were 0. 92 + / - 0. 63 J/min and 8. 18 + / - 4. 52 J/min (p < 0. 001), the mean + / - SD inspiratory times were 1. 98 + / - 0. 86 s and 2. 97 + / - 1. 1 s (p = 0. 001), and the mean + / - SD inspiratory airway/mouth pressures were -1. 1 + / - 0. 6 cm H (2) O and -11. 7 + / - 2. 4 cm H (2) O (p < 0. 001).
