Trial summary

Loss of skeletal muscle strength and skeletal muscle mass occurs with of aging. This are-related decline in skeletal muscle mass and skeletal muscle strength is a major underlying factor contributing to many of the metabolic disorders and frailty of the investigators rapidly expanding aging population.

About this study

Loss of skeletal muscle strength and skeletal muscle mass occurs with of aging. This are-related decline in skeletal muscle mass and skeletal muscle strength is a major underlying factor contributing to many of the metabolic disorders and frailty of the investigators rapidly expanding aging population. Endurance (aerobic) and resistance exercise training programs have been shown to effectively reverse the age-related decline in metabolic and contractile muscle functions. The investigators will measure synthesis rates of individual muscle proteins in 36 each of young (18-30 yrs) and 36 older (> 65 yrs) people to determine their response to 8 weeks each of endurance, resistance, combined endurance and resistance training, or placebo exercise training.

Hypotheses.

  1. to measure fractional synthesis rates of multiple muscle proteins and identify those that are enhanced by an endurance exercise program
  2. to determine whether changes in protein synthesis in response to endurance exercise programs are dependent on age
  3. to measure fractional muscle synthesis rates of multiple muscle proteins and to identify those that are enhanced by a resistance exercise program
  4. to determine whether changes in protein synthesis in response to resistance exercise programs are dependent on age
Conditions
Sarcopenia
Being tested
Endurance exercise, Resistance exercise, Control/Combined training

What participants receive

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

  • Endurance exerciseBehavioural

    Participants will perform 8-weeks of endurance exercise training. Participants will train 5 days per week for 60 min at 65% of VO2 peak.

  • Resistance exerciseBehavioural

    Participants will perform 8-weeks of resistance exercise training. Participants will train 4 days per week for ~60 min. Two days will focus on lower body resistance training and two days will focus on upper body.

  • Control/Combined trainingBehavioural

    Participants will perform 8-weeks of no exercise (control), followed by 8-weeks of combined endurance and resistance training. Participants will endurance train 5 days per week for 30 min at 65% of VO2 peak and resistance train 4 days per week for 30 min.

What is being measured

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

  1. Skeletal Muscle Protein Synthesis

    The investigators will determine the change from baseline in skeletal muscle protein synthesis. Measurments will be performed at baseline and following 8 weeks of exercise training.

    Measured: Measured at week 0 (baseline) and week 8

Secondary outcomes (1)
  1. Mitochondrial Function

    The investigators will determine the change from baseline in mitochondrial function. Measurments will be performed at baseline and following 8 weeks of exercise training.

    Measured: Measured at week 0 (baseline) and week 8

Questions about this trial

What is this clinical trial studying?

A study testing Endurance exercise and Resistance exercise in people with Sarcopenia, run by Mayo Clinic at 1 site 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?

The sponsor lists 3 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 12 Dec 2011. 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 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. 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?

Skeletal Muscle Protein Synthesis (time frame: Measured at week 0 (baseline) and week 8). 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 NCT01489930, 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 12 Dec 2011.
