NCT07142941

Brief 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.

Outcome Measures

Primary Outcomes (3)

  • muscle mass

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

    0 and 12 weeks

  • Handgrip strength

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

    0 and 12 weeks

  • 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.

    0 and 12 weeks

Secondary Outcomes (1)

  • insulin resistance index

    0 and 12 weeks

Study Arms (4)
