Methods: Twenty COPD patients were assigned randomly to two groups and received either 8 weeks of variable resistive loading IMT, or threshold loading IMT (Threshold IMT, Respironics, Inc. USA).View this table:Table 1Both groups performed bi-weekly sessions under supervision and were encouraged to train at the highest tolerable intensity. Results: Two patients did not yet complete the program. Patients in the variable resistive IMT group showed significantly larger increases in maximal inspiratory pressure, endurance time, external work of breathing and inspiratory power during a constant load breathing task.View this table:Table 2Conclusion: 8 weeks of IMT with a variable resistive loading device leads to larger improvements in inspiratory muscle function.
