About this study

Official title: Acute Responses to Arm-Crank Exercise on Cardiovascular Function of Patients With Peripheral Artery Disease: Randomized Crossover Study

The aim of this study is to analyze acute responses of arm-cranking exercise on cardiovascular function of peripheral arterial disease patients and compare it to the main exercise recommendation, walking exercise.

Read the detailed description

Twenty patients with peripheral arterial disease and claudication symptoms will be recruited. The patients will perform three experimental conditions, in randomized order (walking, arm-cranking and control). The exercise conditions will be composed of 15 bouts of 2 minutes exercise with an intensity equivalent to 13-15 on Borg's Subjective Perceived Exertion Scale. During the experimental conditions (walking, arm-cranking and control) blood pressure, heart rate and cerebral blood velocity will be evaluated, along with perceived exertion and affective responses. Before and after experimental conditions, vascular function, blood pressure, heart rate variability, cerebral blood velocity, subjective perceived exertion and affective responses will be evaluated.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ExerciseBehavioural

    Three conditions will be tested: Walking, arm-cranking and control condition.

Study groups in NCT05611021
Study groupRoleWhat they receive
Walking ConditionExperimentalIn the walking condition, the patients will perform fifteen bouts of two minutes of treadmill walking with an interval of two minutes between bouts, at an intensity equivalent to 13-15 on Borg's subjective perceived exertion scale. The condition will have a total of sixty minutes of duration.
Receives: Behavioral: Exercise
Arm-Cranking ConditionActive comparatorIn the arm-cranking condition, the patients will perform fifteen bouts of two minutes of arm-cranking with an interval of two minutes between bouts, at an intensity equivalent to 13-15 on Borg's subjective perceived exertion scale. The condition will have a total of sixty minutes of duration.
Receives: Behavioral: Exercise
Control ConditionSham comparatorThe control condition will consist of resting in the standing position for thirty minutes. The patients will be instructed to rest in the sitting position for two minutes at periods equivalent to the intervals from the exercise conditions, totalling sixty minutes of duration.
Receives: Behavioral: Exercise

What is being measured

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

  1. Change from baseline in vascular function post-exercise in the brachial and femoral arteries.

    Vascular function will be measured in the supine position by the flow-mediated dilation (FMD) technique, through Doppler ultrasonography.

    Measured: Change from baseline at post-intervention, after 20 minutes.

Secondary outcomes (3)
  1. Change from baseline in blood pressure post-exercise.

    Blood pressure will be measured by an automatic monitor.

    Measured: Change from baseline at post-intervention, after 10 minutes.

  2. Change from baseline in heart rate variability post-exercise.

    Autonomic modulation of the cardiovascular system will be measured by the heart rate variability (HRV) technique, by a heart rate monitor valid for this function.

    Measured: Change from baseline at post-intervention, after 30 minutes.

  3. Change from baseline in cerebral blood velocity post-exercise.

    Cerebral blood velocity will be measured by a transcranial doppler ultrasound.

    Measured: Change from baseline at 35 minutes after the beginning of the exercise.

Questions about this trial

What is this clinical trial studying?

A study testing Exercise in people with Intermittent Claudication and Cardiovascular Diseases, run by University of Nove de Julho at 1 site in Brazil.

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 5 inclusion and 2 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 30 Mar 2025. 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 Brazil. 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. Some participants in this study may receive a placebo. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Change from baseline in vascular function post-exercise in the brachial and femoral arteries. (time frame: Change from baseline at post-intervention, after 20 minutes.). 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 30 Mar 2025.
