The Effect of Inspiratory Muscle Warm-Up in Patients With COPD

The IMW protocol applied before each inspiratory muscle training (IMT) session by using a threshold inspiratory muscle trainer. The IMW protocol consists of 2 sets of 30 breaths in 40% of the maximal inspiratory pressure (MIP), with 1 min rest between sets. The intensity of MIP adjusted by two weekly MIP measurements.

The IMT applied twice a day as 30 breath repetitions at 60% of the maximal inspiratory pressure (MIP). The intensity of MIP adjusted by two weekly MIP measurements.

Then the respiratory exercises and aerobic exercise program performed in both groups in each session. Aerobic exercise program; After 5 min of general body warming, applied 20 min with a load of 4-6 according to the modified Borg scale on the treadmill, finished with 5 min whole body cool-down.
