Type 2 Diabetes Post Exercise Arterial Stiffness

September 16, 2025 updated by: University of Illinois at Chicago
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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: GLP-1 Treatment
Individuals diagnosed with type 2 diabetes mellitus (T2DM) who are currently receiving treatment with a glucagon-like peptide 1 (GLP1) agonist.
Other: Exercise 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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Arterial stiffness
Time Frame: Baseline and up to 20 minutes post exercise
Measured via pulse wave velocity
Baseline and up to 20 minutes post exercise

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
