About this study

Official title: Effect of Strength Training and Protein Supplementation on the Muscle Function in Very Old Nursinghome Residents

Three months intervention study, investigating the effect of nutrient supplementation (including 20g of milk protein) twice daily with or without additional heavy resistance exercise three times weekly on muscle size, structure and function in 30 subjects at least 83 years of age.

Primary hypothesis is that the group conducting exercise improves muscle size, structure and function.

Read the detailed description

A total of 30 subjects at least 83 years of age are recruited using advertisements in newspapers, magazines, public places and further personal contact. After information and written ethical consent (in accordance with the Declaration of Helsinki II) health status is evaluated by a medical doctor including blood screening, screening for dementia and routine objective evaluation. If there is no reason to exclude subjects (see exclusion criteria), they are whole-body DXA-scanned (Dual X-ray Absorptiometry) and MR-scanned (Magnetic resonance imaging)(dominant knee and femur) and functional measures (30s chair-stand, 10m and 8m gait speed, DEMMI-test) and strength measures (isometric and isokinetic leg power, power rig, grip strength) and tendon stiffness are measured. At least 4 days after this the first muscle biopsy in the dominant m. vastus lateralis is taken. Hereafter subjects are randomized to one of two groups:

Group one (n=15) is the exercise and nutrition group (HRT). Subjects in this group are to conduct supervised center-based heavy resistance exercise of the lower extremities three times weekly for 12 weeks. As for group two, this group receives nutritional supplementation twice daily throughout the 12 weeks period. Supplementation contains 20g of milk protein and some carbohydrate and lipids.

Group two (n=15) is the nutrition group (PRO). Subjects in this group only receives nutritional supplementation as described above.

After 12 weeks of intervention the same strength- and functional measures are made, DXA- and MR-scans and a second biopsy is made along with tendon stiffness measurement.

Data is collected and analyzed by staff blinded to randomization. Personal data is locked up, and only anonymized data is analyzed. Differences in both primary (m. quadriceps femoris cross sectional area) and secondary outcomes (functional measures, strength measures, muscle cell- and fiber type count, mRNA expression, muscle collagen content and distribution) are evaluated using two-way anova with repeated measures and, if allowed, post-hoc tests. Analysis will be made as intention-to-treat.

Power:

With an expected 10% increase in quadriceps CSA (cross-sectional area) (from 4500 square mm at baseline) with a SD of 600 square mm, power is 82% with alfa 0.05 with inclusion of 15 subjects in each group.

In case of systematic health-issues in response to the intervention, the trial will end immediately.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in quadriceps muscle cross sectional area from baseline to 3 months

    Assessed by MRI scanning of dominant thigh. 8 slices, each of 1cm thickness, separated by 5cm.

    Measured: 0 and 3 months

Secondary outcomes (3)
  1. Change in isometric muscle strength from baseline to 3 months

    Unilateral measurement of isometric strength in m. quadriceps femoris using KinCom.

    Measured: 0 and 3 months

  2. Change in isokinetic muscle strength from baseline to 3 months

    Unilateral isokinetic muscle strength at 60 degrees/s of m. quadriceps femoris.

    Measured: 0 and 3 months

  3. Change in leg power from baseline to 3 months

    Using a Powerrig, unilateral leg extension power is determined.

    Measured: 0 and 3 months

Questions about this trial

What is this clinical trial studying?

A study testing Heavy resistance exercise and nutrition and Nutrition supplement in people with Ageing, run by Bispebjerg Hospital at 1 site in Denmark.

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 1 inclusion and 7 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 12 Oct 2015. 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 Denmark. 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 in quadriceps muscle cross sectional area from baseline to 3 months (time frame: 0 and 3 months). 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 12 Oct 2015.
