About this study

Official title: Effects of Dynamic Strength Training and Isometric Strength Training on Cardiovascular Health Indicators, Mental Health, and Neuromuscular Fitness in Older Adults With Hypertension: A Feasibility Study

This feasibility study aims to evaluate the effects of dynamic strength training and isometric strength training on cardiovascular health indicators, mental health, and neuromuscular fitness in older adults with hypertension. Participants will be randomly assigned to one of the two training modalities and will complete supervised exercise sessions throughout the intervention period. The study will provide preliminary evidence regarding the safety, acceptability, and potential impact of each training modality on health outcomes in this population.

Being tested
Dynamic Strength Training, Isometric Strength Training, No supervised intervention Control

What participants receive

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

  • Dynamic Strength TrainingBehavioural

    The experimental group will perform dynamic strength exercises targeting major muscle groups, progressing in intensity and volume over the 6 weeks. Exercises include 8 major muscle group movements, initially 2 sets of 15 repetitions (Borg 4-6), progressing to 3 sets of 10 repetitions (Borg 5-7) from week 5. Participants will also be advised to perform non-supervised walking 3-5 times per week for ~30 minutes at moderate intensity.

  • Isometric Strength TrainingBehavioural

    The experimental group will perform isometric strength exercises targeting major muscle groups, progressing in intensity and volume over the 6 weeks. Exercises include 8 major muscle group contractions, initially 2 sets of 60 seconds (Borg 4-6), progressing to 3 sets of 40 seconds (Borg 5-7) from week 5. Participants will also be advised to perform non-supervised walking 3-5 times per week for ~30 minutes at moderate intensity.

  • No supervised intervention ControlBehavioural

    This group serves as a control and will not perform any structured exercise program.

Questions about this trial

What is this clinical trial studying?

A study testing Dynamic Strength Training and Isometric Strength Training in people with Hypertension and Elderly (People Aged 65 or More), run by Raphael Mendes Ritti Dias 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 6 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: looking for participants now, as of the sponsor's last update on 1 May 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 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. 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 Adão Luis Monte L Monte, Ms (+55 11 94666 5213, adaoluiz8@outlook.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Recruitment rate (time frame: Baseline and 6 weeks). The study lists 6 primary outcomes in all. 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 May 2026.
