Insulin Use and Respiratory Muscle Strength in Type 2 Diabetes
Respiratory Muscle Strength, Pulmonary Function, and Post-Exercise Recovery Responses According to Insulin Use in Individuals With Type 2 Diabetes Mellitus
Source: ClinicalTrials.gov · Last updated 30 Jan 2026
Brief summary (registry, in English)
This study compares breathing function, breathing muscle strength, and recovery after a walking test in adults with type 2 diabetes, based on whether they use insulin. People with type 2 diabetes will be evaluated during a single study visit at Izmir Bakircay University. Participants will be grouped as either currently using insulin or not using insulin as part of their usual diabetes treatment. All participants will complete the same tests: a breathing test (spirometry), breathing muscle strength tests (maximal inspiratory and expiratory pressures), and a 6-minute walk test. Before the walk test, immediately after the test, and 5 minutes after the test, recovery measures such as heart rate, oxygen saturation, blood pressure, and perceived shortness of breath and fatigue will be recorded. The goal is to understand whether insulin use is associated with differences in breathing and recovery responses in people with type 2 diabetes.
