About this study

Official title: Effects of AM vs. PM Exercise Training on Blood Pressure and Vascular Health in Postmenopausal Females With Hypertension

The treatment of high blood pressure, or hypertension, is multifaceted and can include pharmacological therapies (i.e., medications) and lifestyle modifications such as physical activity. Chronotherapy, which describes timing of a treatment with the body's daily rhythms, has recently been used with hypertension medications and has been shown to be effective at lowering blood pressure and reducing the risk of cardiovascular disease events. Specifically, taking medications in the evening was shown to be more effective than morning medication routines. Little information is available about the effectiveness of chronotherapy combined with exercise (i.e., planned physical activity) interventions in older adults with hypertension. The purpose of this study is to examine how exercise training performed in the morning and early evening affects blood pressure and other measures of blood vessel health in postmenopausal females with hypertension.

Read the detailed description

Blood pressure has an internal rhythm associated with the 24-hr clock. Nocturnal blood pressure (BP) is a key contributor to cardiovascular health and may be improved by exercise. Moreover, the time of day of the exercise may be a key factor. This study aims to evaluate the effects of morning and evening exercise training on BP and other measures of vascular function in older females with hypertension.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Nocturnal systolic blood pressure (BP)

    Change in systolic nocturnal BP (Pre-training - Post-training)

    Measured: 6 weeks

Secondary outcomes (4)
  1. Endothelial function

    Change in flow mediated dilation of the brachial artery (Post-training - Pre-training)

    Measured: 6 weeks

  2. Microvascular function

    Change in rapid onset vasodilation of the popliteal artery

    Measured: 6 weeks

  3. Ambulatory blood pressure

    Change in systolic and diastolic BPs over a 24-hr period (Pre-training - Post-training)

    Measured: 6 weeks

  4. Arterial stiffness

    Change in carotid femoral pulse wave velocity (Pre-training - Post-training)

    Measured: 6 weeks

Questions about this trial

What is this clinical trial studying?

A study testing 6 weeks of exercise training (Pre-training) and 6 weeks of exercise training (Post-training) in people with Hypertension, run by Michigan State University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 1 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Jill Slade, PhD (5178843351, jslade@msu.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Nocturnal systolic blood pressure (BP) (time frame: 6 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Oct 2026.
