About this study

Official title: Randomized Double-blind, Placebo-controlled, Parallel Design, Pilot Study to Assess the Effect of a Nutritional Supplement With Leucine, Along With a Progressive Resistance Exercise Program, on Muscle Strength and Quality of Life in Elderly People.

The purpose of this study is to determine whether a nutritional supplement with an amino acid called leucine along with resistance exercise are effective in the improvement of muscle strength and quality of life in elderly people.

Read the detailed description

Physiological aging is accompanied by functional loss and changes in different organs, including the skeletal muscle, with a progressive reduction in muscle mass. This is called physiological sarcopenia of the elderly.

In any population of autonomous individuals over 65 years, a proportion between 3% and 32% depending on age, meets the criteria of the so-called Frailty Syndrome. Frailty is characterized by a decrease in reserves and resistance to aggression, conferring increased vulnerability, disability and poor vital prognosis.

A feature of the Frailty Syndrome is the potential reversibility of many of the elements at the initial stages of frailty. Currently, available treatment for frailty is limited. One of the tools should be the prevention of sarcopenia, where nutritional treatment and exercise have a vital role.

Protein synthesis in aged muscle can be improved by increasing leucine concentration above physiological levels by a higher intake. Regarding exercise, progressive resistance training is one of the interventions that have shown better results in the increase of mass and muscle strength in elderly people.

The hypothesis raises the possibility that an intervention consisting of a leucine supplement along with progressive resistance training, is superior to the same training program and a placebo in improving muscle strength and quality of life in elderly people.

Questions about this trial

What is this clinical trial studying?

A study testing L-leucine., Maltodextrin. and Exercise program. in people with Ageing, run by Hospital Clinic of Barcelona 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 12 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 9 Oct 2014. 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. 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?

Muscle strength. (time frame: Baseline, 4 weeks, 12 weeks). 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 NCT00929929, which also lists 1 linked publication.

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 9 Oct 2014.
