Dynamic and Isometric Strength Training in Older Adults With Hypertension

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

Sponsor

Raphael Mendes Ritti Dias

Enrollment

60 participants

Start Date

Mar 1, 2026

Study Type

INTERVENTIONAL

Conditions

Hypertension Elderly (People Aged 65 or More)

Summary

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.

Eligibility

Min Age: 60 Years

Inclusion Criteria6

Diagnosis of arterial hypertension and currently taking antihypertensive medication
Age 60 years or older
Resting blood pressure below 160/95 mmHg
No high cardiovascular risk according to the American College of Sports Medicine criteria (for participants with type 2 diabetes, glycemic control with fasting glucose <100 mg/dL and postprandial glucose <140 mg/dL)
Not participating in a structured exercise program for more than three months
No cognitive or functional limitations that prevent participation in the exercise program

Exclusion Criteria4

Presence of acute illnesses, such as influenza, sinusitis, gastroenteritis, urinary tract infection, fever, inflammatory processes, or any clinical condition requiring rest or that may compromise safety during assessments or training.
Decompensated clinical conditions, including: Blood pressure spikes, Chest pain, Uncontrolled arrhythmias, Shortness of breath at rest, Asthma exacerbations, Decompensated diabetes mellitus, characterized by Persistently elevated blood glucose levels (fasting glucose > 180 mg/dL or postprandial glucose > 250 mg/dL)
Irregular use of medication
Any unstable clinical condition or condition that represents additional risk for the practice of physical exercise.

Interventions

BEHAVIORALDynamic Strength Training

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.

BEHAVIORALIsometric Strength Training

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.

BEHAVIORALNo supervised intervention Control

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