Investigation of the Effect of Functional Respiratory Muscle Training on Functional Level, Balance and Biochemical Parameters in Elderly Individuals.

The patients included in the study will be randomly divided into two groups as the study and control groups. Randomization will be provided by a computer-aided program. The patients in the study and control groups will be evaluated at the beginning and after six weeks. Functional Respiratory Muscle Training will be given to the study group with the Powerbreathe Respironics® (UK) device. The initial training intensity will be set at 50% (threshold loading) of the MIP value measured in the patient's first evaluation. The patient will be re-evaluated and the new MIP value will be measured, increasing by 10% every 2 weeks, and the training intensity will be adjusted by calculating the measured MIP value. Patients will be asked to work four days a week until the exercise sets are completed.

In the control group, the same balance exercises will be performed and will not be changed for six weeks.
