Counteracting Age-related Loss of Skeletal Muscle Mass (CALM) (CALM)

April 17, 2023 updated by: Lars Holm, Bispebjerg Hospital

Counteracting Age-related Loss of Skeletal Muscle Mass

Up to 66 healthy elderly individuals (at least 65 years old) are recruited as subjects. They will be recruited as a subgroup to protocol ID: H-4-2013-070.

Upon inclusion, each individual will be randomized into one of the five groups stratified according to gender (M/F) and 30s chair stand (<16 OR ≥16). The five groups are: Heavy Resistance Training (N=12), Light Intensity Training (N=12), Protein Whey (N=15), Protein Collagen (N=15) and Carbohydrate (N=12). The individuals randomized into one of the supplementation groups (Protein Whey, Protein Collagen or Carbohydrate) will be blinded to the supplement content.

Assessments will be performed at Baseline (before intervention start) and after 12 months of intervention.

The primary outcomes are measures of muscle protein synthesis rate measured as the fractional synthesis rate from Baseline to 12 months of intervention.

The hypotheses are i) that basal and protein-stimulated muscle protein synthesis rates are elevated in the exercise training groups after 12 months of intervention. ii) prolonged intake of protein of different quality will improve the muscle protein synthetic response to protein intake after 12 months of intervention.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Basal overnight fasted muscle protein synthesis rate.
Time Frame: Baseline and 12 months
Overnight fasting muscle protein synthesis will be measured at Baseline and after 12 months intervention by applying stable isotope amino acid tracer techniques and calculating the fractional synthesis rates.
Baseline and 12 months
Muscle protein synthesis rate response to protein intake from basal overnight fasted state.
Time Frame: Baseline and 12 months

Change in the response of muscle protein synthesis rate to a single intake of 20 g whey protein and 10 g carbohydrate from the basal overnight fasted state from Baseline to 12 months intervention.

Statistical analysis:

Outcome 1 will be subtracted outcome 2 to calculate the difference FSR at baseline and 12 month respectively. The difference at baseline will be subtracted the difference at 12 month to calculate the delta difference. This delta difference will be analyzed as a modified intention-to-treat as well as per protocol, and we will test the following groups against each other using one-way analysis of variance of the relative group changes from baseline to 12 months: (1) WHEY vs. COLL vs. CARB and (2) HRTW vs. LITW vs. WHEY
Baseline and 12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Muscle protein turnover molecular signaling and gene expression
Time Frame: Baseline and 12 months
Muscle protein turnover regulation signaling and gene expression will be measured in the muscle tissue obtained for muscle protein synthesis measurements. Protein and protein activation status will be analysed by Western blot techniques. Gene expressions will be analysed by real time RT-PCR techniques.
