Type 2 Diabetes
Conditions
Brief summary
The overall aim of this research proposal is to determine the impact of GLP1 agonists on post-exercise arterial stiffness. Therefore, the investigators will examine the cardiovascular responses to exercise in individuals with Type 2 Diabetes mellitus (T2DM) taking these medications during and following a graded maximal exercise test.
Detailed description
Type 2 diabetes mellitus (T2DM) is a significant public health concern associated with increased cardiovascular morbidity and mortality. Notably, individuals with T2DM often exhibit increased arterial stiffness, a key indicator of cardiovascular risk. Pharmacological interventions such as GLP1 agonists have emerged as crucial treatments for T2DM, offering glycemic control and potential cardiovascular benefits, including improvements in blood pressure and arterial stiffness. However, while the effects of GLP1 agonists on glycemic control and blood pressure regulation have been explored, their impact on arterial stiffness, specifically in response to exercise, remains largely unexplored in individuals with T2DM. Arterial stiffness is a critical marker of cardiovascular health, and its reduction is associated with decreased cardiovascular risk which include lowered blood pressure. Therefore, the overall aim of this research is to investigate whether GLP1 agonists attenuate arterial stiffness post exercise and reduce peak exercise blood pressure in individuals with T2DM.
Interventions
OTHERExercise Test
Exercise capacity will be measured as peak oxygen consumption (peakVO2) using an incremental exercise test on a cycle ergometer with an open-circuit spirometry system (TrueOne, Parvo Medics, Sandy, UT) to analyze expired gases. Exercise testing will follow the American College of Sports Medicine and American Heart Association guidelines. The investigators will use a graded protocol, starting with a warm-up at 0 watts for 5 minutes, followed by 15 watt increments every 2 minutes until volitional fatigue.

Intervention model description
The study will involve individuals diagnosed with type 2 diabetes mellitus (T2DM) who are currently receiving treatment with a glucagon-like peptide 1 (GLP1) agonist compared to a control group of individuals diagnosed with type 2 diabetes mellitus (T2DM) who are receiving treatment with drugs other than glucagon-like peptide 1 (GLP1) agonists. The study will not involve changes to medications for the participants.
