Trial summary

The investigators aimed to examine if β-hydroxy-β-methylbutyrate (HMB) supplementation enhances the effects of exercise on muscle mass, physical performance and insulin resistance and observe potential residual effects in older diabetes with low muscle mass, and to find the optimal treatment plan.

About this study

Official title: Effects of Exercise and/or β-hydroxy-β-methylbutyrate Supplementation on Muscle Mass, Physical Performance and Insulin Resistance in Older Diabetes With Low Muscle Mass: a Randomized, Double-blind, Placebo-controlled Trial

The investigators aimed to examine if β-hydroxy-β-methylbutyrate (HMB) supplementation enhances the effects of exercise on muscle mass, physical performance and insulin resistance and observe potential residual effects in older diabetes with low muscle mass, and to find the optimal treatment plan.

Read the detailed description

The interaction between exercise and nutritional supplementation is unclear among older diabetes at risk of sarcopenia. The investigators aimed to examine if β-hydroxy-β-methylbutyrate (HMB) supplementation enhances the effects of exercise on muscle mass, physical performance and insulin resistance and observe potential residual effects in older diabetes with low muscle mass, and to find the optimal treatment plan. This 12-wk, randomized, double-blind, placebo controlled, 2 × 2 factorial design (exercise-only, HMB-only, both, and none) trial included 120 older diabetes aged 60-80 y with skeletal muscle index <5.7 kg/m2 for women, and <7.0 kg/m2 for men, and was followed by a 12-wk observational period.

What participants receive

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

  • HMBDietary supplement

    Participants were instructed to take active products including 3000 mg calcium-HMB per day

  • ExerciseBehavioural

    Participants allocated to the exercise programs were provided 45 min of supervised sessions on 2 nonconsecutive days per week

  • PlaceboDietary supplement

    Participants were instructed to take active products including equal in quality resistant dextrin per day

  • EducationOther

    Participants were given health education and educational manuals

What is being measured

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

  1. muscle mass

    Body composition including muscle mass was measured using a segmental multifrequency bioelectrical impedance device (Inbody)

    Measured: 0 and 12 weeks

  2. Handgrip strength

    Handgrip strength was measured using a handheld Smedley-type dynamometer.

    Measured: 0 and 12 weeks

  3. 5-repetition sit-to-stand time

    Participants folded their arms across their chests and were instructed to stand-up completely and make firm contact when sitting. Timing began on the command "go" and ceased when the participants sat after the fifth stand-up. Participants were allowed a practice trial of 2 repetitions before the timing of 2 test trials of 5 repetitions.

    Measured: 0 and 12 weeks

Secondary outcomes (1)
  1. insulin resistance index

    Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) was calculated as follow:

    HOMA-IR=(Fasting Insulin (μU/mL)×Fasting Glucose (mg/dL))/405

    Measured: 0 and 12 weeks

Questions about this trial

What is this clinical trial studying?

A study testing HMB, Exercise and Education in people with Diabetes and Low Muscle Mass, run by Wu Shangling.

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 5 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: opening soon, as of the sponsor's last update on 31 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Shangling Wu ((020)87338179, wushling6@mail.sysu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

muscle mass (time frame: 0 and 12 weeks). The study lists 3 primary outcomes in all. 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 31 Mar 2026.
