NCT07321535

Brief Summary

The goal of this clinical trial is to learn if a traditional Chinese medicine formula called "Huangjing Yangji Formula," combined with elastic band resistance training, works better than exercise alone to improve physical function and muscle strength in older adults with sarcopenia (age-related muscle loss). The main questions it aims to answer are: Does the combined treatment improve participants' overall physical performance scores more than exercise with a placebo? Does it lead to better outcomes in walking speed, balance, muscle strength, body composition, nutrition, mood, sleep, and overall quality of life? Researchers will compare two groups. One group will take the real Huangjing Yangji Formula granules and do the standardized elastic band resistance training. The other group will take placebo granules (a look-alike mixture with no active medicine) and do the same training. Participants will: Take the assigned granules twice daily for 3 months. Complete a standardized elastic band exercise program 3 times per week for 3 months (with both group and home sessions). Attend three assessment visits (at the start, after 3 months, and 1 month after treatment) for tests and questionnaires. Provide blood samples at the start and after 3 months for routine safety tests and special muscle health markers.

Outcome Measures

Primary Outcomes (1)

  • Short Physical Performance Battery (SPPB) Score

    The SPPB is a composite score ranging from 0 to 12 that assesses lower extremity physical function. It combines three tests: standing balance, 4-meter walking speed, and time to complete five chair stands. Scores are interpreted as: 0-3 (severe limitation), 4-6 (mild limitation), 7-9 (normal function), and 10-12 (excellent function). A higher score indicates better physical performance.

    Baseline, 3 months, and 4 months (1-month follow-up).

Secondary Outcomes (17)

  • 4-Meter Walking Speed

    Baseline, 3 months, and 4 months (1-month follow-up).

  • Timed Up and Go Test (TUG)

    Baseline, 3 months, and 4 months (1-month follow-up).

  • Handgrip Strength

    Baseline, 3 months, and 4 months (1-month follow-up).

  • Tinetti Performance-Oriented Mobility Assessment (POMA)

    Baseline, 3 months, and 4 months (1-month follow-up).

  • Appendicular Skeletal Muscle Index (ASMI)

    Baseline, 3 months, and 4 months (1-month follow-up).

  • +12 more secondary outcomes

Huangjing Yangji Formula + Training

EXPERIMENTAL

Participants in this group will take "Huangjing Yangji Formula" granules orally. The formula consists of Polygonati rhizoma (Huangjing) 15g, Codonopsis radix (Dangshen) 10g, Rehmanniae radix praeparata (Shudi) 9g, Angelica sinensis radix (Danggui) 6g, Cistanches herba (Roucongrong) 9g, Lycii fructus (Gouqi) 12g, Poria (Fuling) 9g, and Crataegi fructus (Shanzha) 6g per daily dose. The granules are taken twice daily, 30 minutes after meals, for a total treatment period of 3 months. Additionally, all participants in this group will simultaneously complete the standardized elastic band resistance training program 3 times per week for 3 months.

Placebo + Training

PLACEBO COMPARATOR

Participants in this group will take matched placebo granules orally. The placebo is designed to be identical to the investigational "Huangjing Yangji Formula" granules in appearance, color, odor, packaging, and solubility, but it contains no active herbal components. The placebo granules are taken twice daily, 30 minutes after meals, for a total treatment period of 3 months. Additionally, all participants in this group will simultaneously complete the identical standardized elastic band resistance training program 3 times per week for 3 months.

Drug: Placebo Granules for Huangjing Yangji FormulaBehavioral: Standardized Elastic Band Resistance Training Program

Interventions

Matched placebo granules. This preparation is specifically designed to be indistinguishable from the active "Huangjing Yangji Formula Granules" in terms of appearance, color, odor, packaging, and solubility. It contains no pharmacologically active herbal components. Administered orally in the same manner (twice daily, 30 minutes after meals) for 3 months.

Placebo + Training

A structured, progressive resistance training program using elastic bands. Participants train 3 times per week for 3 months. Each 60-minute session includes warm-up, 10 core strength exercises (e.g., standing row, leg extension, bridge), and cool-down. Intensity is progressively increased from low (approximately 40-60% of 1-RM) to medium-high (approximately 60-80% of 1-RM) resistance. Sessions are supervised once weekly, with twice-weekly home-based sessions.

Investigational herbal granule formulation. Each daily dose contains: Polygonati rhizoma (Huangjing) 15g, Codonopsis radix (Dangshen) 10g, Rehmanniae radix praeparata (Shudi) 9g, Angelica sinensis radix (Danggui) 6g, Cistanches herba (Roucongrong) 9g, Lycii fructus (Gouqi) 12g, Poria (Fuling) 9g, and Crataegi fructus (Shanzha) 6g. Administered orally as granules dissolved in water, twice daily (30 minutes after meals), for a period of 3 months.
