Trial summary

Frailty is most often defined as a syndrome of physiological decline in late life, characterized by marked vulnerability to adverse health outcomes. Intervention such as exercise, especially resistance exercise, has proven to be effective to improve frail condition in the elderly in the previous literature. Read more about this study

About this study

Official title: Effect of Blood Flow Restriction Resistance Training on Muscle Strength and Functional Performance in Frail Older Adults

Frailty is most often defined as a syndrome of physiological decline in late life, characterized by marked vulnerability to adverse health outcomes. Intervention such as exercise, especially resistance exercise, has proven to be effective to improve frail condition in the elderly in the previous literature. However, blood flow restriction (BFR) training, a new resistance exercise training method, need merely lower resistance power and shorter training duration compared with traditional resistance exercise. Previous researches also demonstrated BFR can increase muscle mass and muscle strength in the healthy elderly but the effect of BFR training on the pre-frail or frail elderly is unknown. The aim of this study will test the effect of BFR training on muscle strength and functional performance in pre-frail or frail elderly. Participants aged over 60 years old with clinical frailty score between 3 to 5 will be recruited. Participants will be assigned to two groups using randomized block design with BFR training and control group. Structured questionnaire and physical function measurement will be used to assess the pre-intervention condition and outcome of different interventions. The participants will be assessed before training (pre-test), 3 weeks after training, and 6 weeks after training (post-test), and followed up at one and three months after training. Physical function measurement will include hand grip, muscle mass over trunk and extremity, muscle strength of lower extremity, gait speed and timed up and go test. Two-way repeated measures analysis of variance will be used to test the pre-test, 3-week, post-test and follow-ups difference between the two groups.

What participants receive

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

  • Blood flow restriction resistance trainingOther

    The participants will carry weights and perform certain resistance exercises, such as step-up, sit-to-stand, and tip-toe-standing. The experimental group will execute the training with blood flow restriction.

  • Resistance trainingOther

    The participants will carry weights and perform certain resistance exercises, such as step-up, sit-to-stand, and tip-toe-standing. The control group will execute the training without blood flow restriction.

Questions about this trial

What is this clinical trial studying?

A study testing Blood flow restriction resistance training and Resistance training in people with Frailty, run by National Cheng Kung University at 1 site in Taiwan.

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 6 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 11 Jan 2022. 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 Taiwan. 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?

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 of muscle strength of the lower extremities (time frame: Before training, 3 and 6 weeks after training, and one and two months follow-ups). 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?
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 11 Jan 2022.
