- Gender: ALL
- Minimum Age: 35 Years
- Maximum Age: 80 Years
- Healthy Volunteers: f

Study Arms:
- Arm 1: EMST (Type: ACTIVE_COMPARATOR): The experimental group receives five weeks of expiratory muscle strength training (EMST) using a positive pressure threshold device
- Arm 2: Sham group (Type: SHAM_COMPARATOR): The Sham group undergoes the same 5-week EMST exercise as the experimental group using the same device but without a spring for minimal pressure load

Based on this trial design, predict the completion outcome and termination type (if applicable).
