About this study

Official title: Effects of Exercise Training as a Non-pharmacological Treatment for Metabolic Syndrome and Its Interactions With Subjects Habitual Medications.

To analyze the effects of different exercise training modalities (continuous, intervallic, and resistance training) on cardiorespiratory and metabolic fitness of metabolic syndrome patients when this training interacts with their habitual medication.

Read the detailed description

Objective: The purpose is to study in a group of adults with metabolic syndrome and obesity, the effects of different modalities of exercise training on cardiorespiratory and metabolic fitness. The main objective is to weight the effects of exercise training separately and in conjunction with the subject's habitual pharmacological treatment to identify the best combination of drug and exercise.

Methods and design: Randomized, pretest-posttest control group experimental design. Project developed in a single center with the collaboration of the regional public health system.

Subjects: Will be referred by their primary care physicians to our study unit. Up to 40 subjects all of them with metabolic syndrome will be recruited (at least 20% women).

Measurements:

  1. Specifically, the investigators, will study cardiovascular adaptations that increase, i) maximal aerobic capacity measured by VO2max, ii) anaerobic and respiratory compensation point ventilatory thresholds, iii) arterial stiffness, measured by pulse wave velocity (SphygmoCor System), v) central and peripheral blood pressure, and iv) biological markers of endothelial dysfunction using reactive hyperemia with a laser Doppler fluxmeter in central and peripheral blood vessels.
  2. The metabolic adaptations under study will include, i) insulin sensitivity by HOMA-IR, ii) fat oxidation by indirect calorimetry

Study groupRoleWhat they receive
PLACEBO FIRST THEN MEDICATEDExperimentalSubjects first receive the PLACEBO tablet during 72 hours (full withdrawal). After a week of taking again their medication (MEDICATION TRIAL), they will be tested again. This procedure will be repeated before and after 4 months of aerobic training.
Receives: Drug: MEDICATION AND EXERCISE TRAINING
MEDICATED FIRST THEN PLACEBOExperimentalSubjects first receive their antihypertensive MEDICATION tablet (habitual dose prescribed by their primary care doctors). After a week they will take a PLACEBO tablet for 72 hours and will be tested again. This procedure will be repeated before and after 4 months of aerobic training.

  2. Diastolic Blood Pressure

    Determined using a ECG-gated automated sphygmomanometer. Value is the difference between the placebo and antihypertensive medication.

    Measured: Subject tested before and after 4 months of training. At baseline tested with and without medication separated 72 hours. Post training tested with and without medication separated 72 hours.

  3. Mean Arterial Pressure

    Determined using a ECG-gated automated sphygmomanometer. Value is the difference between the placebo and antihypertensive medication.

    Measured: Subject tested before and after 4 months of training. At baseline tested with and without medication separated 72 hours. Post training tested with and without medication separated 72 hours.

Secondary outcomes (3)
  1. Maximal Oxygen Consumption Rate During Exercise (VO2max).

    Index of cardiorespiratory fitness assessed during an incremental cycle-ergometer test using an indirect calorimetry system.

    Value is the difference between the placebo and antihypertensive medication.

    Measured: Subject tested before and after 4 months of training. At baseline tested with and without medication separated 72 hours. Post training tested with and without medication separated 72 hours.

  2. Maximal Rate of Fat Oxidation.

    Calculated in grams per min during the incremental cycloergometer test wih the use of indirect calorimetry system.

    Value is the difference between the placebo and antihypertensive medication.

    Measured: Subject tested before and after 4 months of training. At baseline tested with and without medication separated 72 hours. Post training tested with and without medication separated 72 hours.

  3. Body Weight

    Nude body weight. Value is the difference between the placebo and antihypertensive medication.

    Measured: Subject tested before and after 4 months of training. At baseline tested with and without medication separated 72 hours. Post training tested with and without medication separated 72 hours.

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing MEDICATION AND EXERCISE TRAINING in people with Exercise Therapy and Metabolic Syndrome X, run by University of Castilla-La Mancha at 1 site in Spain.

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 2 inclusion and 4 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: finished, as of the sponsor's last update on 14 Jun 2021. 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 Spain. 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.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 May 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Systolic Blood Pressure (time frame: Subject tested before and after 4 months of training. At baseline tested with and without medication separated 72 hours. Post training tested with and without medication separated 72 hours.). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03019796, which also lists 27 linked publications.

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 14 Jun 2021; AzTrials last refreshed its copy on 28 Oct 2026.
