简要总结
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.

结局指标
主要结局
Maximal Inspiratory Pressure
时间窗: Eight weeks
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.
Diaphragm Thickness Measurement at Total Lung Capacity (TLC)
时间窗: Eight weeks
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).
Diaphragm Elastography Measurement at Total Lung Capacity (TLC)
时间窗: Eight weeks
Diaphragm elastography measurement will be performed with the Toshiba Aplio 500 ultrasound device at Istanbul University, Istanbul Faculty of Medicine, Department of Sports Medicine. The measurement will be performed on the right hemidiaphragm with the volunteer in the supine position. The measurement will be performed 2 times and the average value will be calculated. The value will be expressed in kPa (kilopascal).
Diaphragm Thickness Measurement at Quiet Breathing
时间窗: Eight weeks
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).

The value will be expressed in kPa (kilopascal).
Exercise Capacity Measurement
时间窗: Eight weeks
The exercise capacity of the participants will be evaluated with six-minute walk test (6MWT).
Diaphragm Thickness Measurement at Functional Residual Capacity (FRC)
时间窗: Eight weeks
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).
