Sarcopenia, according to EWGSOP2(European Working Group on Sarcopenia in Older People-2019), is a progressive and generalised skeletal muscle disorder that is associated with increased likelihood of adverse outcomes including falls, fractures, physical disability, and mortality. Changes in muscle strength and muscle mass that occur with aging are not only limited to the skeletal muscles surrounding the axial and appendicular skeleton, but also occur in the respiratory muscles. With aging, respiratory muscle strength decreases, muscle mass decreases, and respiratory functions decline. In sarcopenic individuals; maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP) and diaphragm muscle thickness values were found to be significantly lower.
It is known that exercise is the most effective and valid way to treat sarcopenia. Considering the positive effects of IMT (Inspiratory Muscle Training) on both respiratory and physical parameters in the elderly population, we think that these changes can also be observed in sarcopenic individuals. Therefore, the aim of this study is to investigate the effects of inspiratory muscle training on diaphragm thickness, inspiratory muscle strength, and exercise capacity in sarcopenic individuals.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Training Group | Experimental | Individuals with sarcopenia in this group will perform three sets of 10 repetitions, with 1-minute of rest allocated between sets, twice daily, 5 days per week for eight weeks. The first session will be performed supervised in a clinic, other sessions will be performed at home. Telephone contact will be held twice a week to ensure the completion of training and clarify any doubts. Training intensity will be set at 60% of the maximum inspiratory pressure for the first week then will be set at %70 of the maximum inspiratory pressure for the second week. After the second week, training intensity will be increased as much as participants tolerated at the start of each week. |
|
| Sham Group | Sham Comparator | Individuals with sarcopenia in this group will perform two sets of 10 repetitions, with 1-minute of rest allocated between sets, one time a day, 2 days per week for eight weeks. The first session will be performed supervised in a clinic, other sessions will be performed at home. Training intensity will be set at 10 cm Hâ‚‚O for all training sessions. |

| Inspiratory Muscle Training | Device | A mechanical pressure threshold loading device (POWERbreathe, POWERbreathe International Ltd, UK) will be used for the training. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Maximal Inspiratory Pressure | Maximal inspiratory pressure (MIP) will be measured using an electronic mouth pressure device (Micro RPM). At least 3 repetitions will be performed and the measurement will be repeated until there is less than a 5% difference between the best and the second-best measurement. | Eight weeks |
| Diaphragm Thickness Measurement at Quiet Breathing | Diaphragm thickness measurement will be performed with the Toshiba Aplio 500 ultrasound device at Istanbul University, Istanbul Faculty of Medicine, Department of Sports Medicine. Diaphragm thickness will be measured as the vertical distance between the pleural and peritoneal layer at quiet breathing. Measurement will be performed on the right hemidiaphragm with the volunteer in the supine position. The measurement will be performed 3 times and the average value will be calculated. The value will be expressed in millimeters (mm). | Eight weeks |
| Diaphragm Thickness Measurement at Total Lung Capacity (TLC) | Diaphragm thickness measurement will be performed with the Toshiba Aplio 500 ultrasound device at Istanbul University, Istanbul Faculty of Medicine, Department of Sports Medicine. Diaphragm thickness will be measured as the vertical distance between the pleural and peritoneal layer at Total Lung Capacity (TLC). Measurement will be performed on the right hemidiaphragm with the volunteer in the supine position. The measurement will be performed 3 times and the average value will be calculated. The value will be expressed in millimeters (mm). | Eight weeks |
| Diaphragm Thickness Measurement at Functional Residual Capacity (FRC) | Diaphragm thickness measurement will be performed with the Toshiba Aplio 500 ultrasound device at Istanbul University, Istanbul Faculty of Medicine, Department of Sports Medicine. Diaphragm thickness will be measured as the vertical distance between the pleural and peritoneal layer at Functional Residual Capacity [FRC]. Measurement will be performed on the right hemidiaphragm with the volunteer in the supine position. The measurement will be performed 3 times and the average value will be calculated. The value will be expressed in millimeters (mm). |
| Measure | Description | Time Frame |
|---|---|---|
| Pulmonary Function Test [Forced Vital Capacity (FVC)] | The pulmonary function test [Forced Vital Capacity (FVC)] will be performed with Spirobank Mir (SN A23-048) / Winspro v.3.1.1 open circuit spirometer. | Eight weeks |
| Pulmonary Function Test [Forced Expiratory Volume in the first second (FEV1)] |
