Brief Summary

Sarcopenia and physical frailty are highly prevalent among institutionalized older adults and are major contributors to functional decline, reduced mobility, and loss of independence. Combined exercise and targeted nutritional strategies have emerged as promising approaches to mitigate these age-related impairments. This randomized, double-blind, placebo-controlled, parallel-group clinical trial aims to evaluate the independent and combined effects of creatine monohydrate (CRE) and β-hydroxy-β-methylbutyrate (HMB), administered alongside a supervised multicomponent exercise program, on physical function, body composition, cognitive performance, and quality of life in institutionalized older adults with physical frailty and sarcopenia. A total of 50 adults aged ≥65 years were enrolled and randomized to one of four intervention groups for 12 weeks: placebo plus exercise, creatine plus exercise, HMB plus exercise, or creatine plus HMB plus exercise. A supplement-free follow-up period will be conducted to evaluate the sustainability of intervention effects. In addition to clinical and functional outcomes, the study incorporates molecular and biological assessments to explore mechanistic pathways underlying functional adaptation and interindividual variability in response to the interventions.

Outcome Measures

Primary Outcomes (3)

  • Short Physical Performance Battery (SPPB)

    The SPPB assesses lower-extremity physical function through balance, gait speed, and chair stand components, generating a total score ranging from 0 to 12 (higher scores indicate better physical performance). Only the total score will be analyzed as the primary outcome.

    Baseline, Week 12 (end of intervention), and 3-month follow-up

  • Timed Up and Go (TUG)

    Time in seconds to rise from a chair, walk 3 meters, turn around, return, and sit down. Lower times indicate better mobility and balance.

    Baseline, Week 12 (end of intervention), and 3-month follow-up

  • Appendicular Lean Mass (ALM, kg) by DEXA

    Appendicular lean mass (sum of arms and legs lean tissue) measured in kilograms using DEXA. Higher values indicate greater muscle mass in limbs.

    Baseline, Week 12 (end of intervention), and 3-month follow-up

Secondary Outcomes (29)

  • Grip Strength

    Baseline, Week 12 (end of intervention), and 3-month follow-up

  • Leg and Back Isometric Strength

    Baseline, Week 12 (end of intervention), and 3-month follow-up

  • Seated Arm Curl Test

    Baseline, Week 12 (end of intervention), and 3-month follow-up

  • Barthel Index

    Baseline, Week 12 (end of intervention), and 3-month follow-up

  • Mini Nutritional Assessment (MNA)

    Baseline, Week 12 (end of intervention), and 3-month follow-up
