About this study

Official title: A Double Blind Study on the Efficacy of a Combination of Beta-hydroxy-beta-methylbutyrate and Vitamin D on Muscular Strength and Functionality in Older Adults.

The purpose of the study is to

  • Test the effect of a dietary supplement beta-hydroxy-beta-methylbutyrate (HMB) with and without Vitamin D to prevent and reverse the losses of muscular strength and functionality in older adults.
Read more

The second aim of the study is to determine if HMB and Vitamin D improves markers of bone turnover in adults aged 60 plus years. HMB is a dietary supplement that comes from the amino acid leucine. HMB is found in foods and is made in your body after you eat protein (meat). Subjects will be randomized to one of four dietary supplement groups and will participate in a 3-day per week exercise program for 12 weeks. Each exercise day will be about 60 minutes long consisting of strength training exercises utilizing Theraband® stretch cords and jumping.

Subjects will consume the dietary supplement 2 times per day for 12 weeks. Tests will consist of the following:

  • Measuring the strength of subjects' legs by using a Isokinetic Dynamometer
  • Measuring body composition
  • Measuring hand-grip strength using a hand-grip dynamometer
  • Measuring functional mobility, balance and agility by the time it takes for you to rise from a chair, walk around a cone 8 feet in front of the chair and return to the chair (Up-\&-Go Test
  • Filling out questionnaires and having blood drawn for biochemical measurements. Testing will be performed at the beginning and at 4, 8 and 12 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Vitamin D, Beta-hydroxy-Beta-methylbutyrate and Beta-hydroxy-Beta-methylbutyrate and Vitamin D in people with Muscle Strength and Sarcopenia, run by Metabolic Technologies Inc. at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

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 17 Sep 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Muscular Strength and functionality (time frame: 12 weeks). 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 17 Sep 2014.
