Respiratory Muscle Activations During Stable Threshold Load and Increasing Threshold Load Endurance Tests in COPD

In the literature, it has been observed that there is an increase in respiratory muscle activity in individuals with COPD due to the increase in respiratory workload and in response to the loads given by respiratory muscle training devices. However, no study has been found in the literature comparing the activation of respiratory muscles during constant threshold load endurance test and increasing threshold load endurance test performed with respiratory muscle training devices, which are important for respiratory muscle function evaluation. With this planned study, it is aimed to contribute to the literature by examining the changes in muscle activation during the constant threshold load and increasing threshold load endurance tests where different workloads are given and by comparing these changes.
