About

The aim of this study is to examine the effects of high-intensity and low-intensity inspiratory muscle training added to the standard pulmonary rehabilitation exercise program including aerobic and peripheral muscle strengthening training on respiratory muscle function, exercise capacity, dyspnea and health-related quality of life in asthmatic patients. The aim of the study was to examine whether there are intra-group changes and inter-group differences in the groups where low and high intensity inspiratory muscle training was applied. The cases meeting the inclusion criteria will be randomized and divided into two groups, the groups will be named as High Intensity Inspiratory Muscle Training Group (H-IMT) and Low Intensity Inspiratory Muscle Training Group (L-IMT).

Full description

Patients diagnosed with asthma by a chest diseases specialist and referred to pulmonary rehabilitation will be included in the study. The cases meeting the inclusion criteria will be randomized and divided into two groups, the groups will be named as High Intensity Inspiratory Muscle Training Group (H-IMT) and Low Intensity Inspiratory Muscle Training Group (L-IMT). Inspiratory muscle training will be carried out in the form of 2 minutes of work and 1 minute break for a total of 21 minutes, starting from 80% of the maximum inspiratory pressure determined by mouth pressure measurement for the H-IMT Group and 30% for the L-IMT Group. An 8-week training will be carried out by increasing the planned load by 5% every two weeks. In addition, breathing exercises, strengthening exercises and walking training on flat ground will be given to both groups in the form of a home program. The training program will be 8 weeks in total, 3 days a week. will be given online exercises, synchronized 2 days a week, and a home program for 1 day, accompanied by a physiotherapist, via videoconference on the smartphone. A total of 24 sessions will be held.
