The aim of this study is to investigate the effects of the home-based inspiratory muscle training program on lung functions, dyspnea, inspiratory muscle strength, functional capacity and quality of life in patients with idiopathic pulmonary fibrosis. Patients are evaluated before the inspiratory muscle training and after 8 weeks of training.
The IMT protocol consisted of home-based high-intensity daily training - two cycles of 30 breaths with a 1-min rest between sets, twice a day for 8 weeks using an IMT Threshold device (Threshold IMT Philips® Respironics, Inc). The intensity of the training was set to 50% of each patient's maximal inspiratory pressure measured every week and was adjusted weekly based on the modified Borg scale from 4 to 6 regarding respiratory effort performed during the session. Patients are evaluated before the inspiratory muscle training and after 8 weeks of training.

The IMT protocol will consist of home-based daily training - two cycles of 30 breaths with a 1-min rest between sets, twice a day for 8 weeks using an IMT Threshold device (Threshold IMT Philips® Respironics, Inc). The intensity of the training will be set to the lowest intensity of the IMT Threshold device.

Change in inspiratory muscle strength
MIP
Time frame: 8 weeks
Change in percentages of forced expiratory volume in one second
Lung function tests: Percentages of forced expiratory volume in one second (FEV1).
Time frame: 8 weeks
Change in percentages of forced vital capacity
Lung function tests: Percentages of forced vital capacity (FVC).

Change in diffusing capacity of the lung for carbon monoxide
Lung function tests: Diffusing capacity of the lung for carbon monoxide (DLCO).
Time frame: 8 weeks
Change in Dyspnea
The modified Medical Research Council (mMRC) Dyspnea Scale was used to evaluate the severity of dyspnea. Commonly used in the assessment of dyspnea in COPD, mMRC has a five-level scoring system ranging from 0 to 4. A high score indicates an increased sense of dyspnea.
Time frame: 8 weeks
Change in Functional capacity
Maximal distance in 6 minute walk test
Time frame: 8 weeks
