Assessment

Primary outcomes

Physical function (walking speed [6-meter walk test] and handgrip strength); between-group comparison at 16 weeks

Key secondary outcomes

1) Aging-related markers in immune cells; oxidative stress-related markers in T cells; high-sensitivity C-reactive protein (hs-CRP); Olink Target 48
2) Body composition (muscle mass measured by InBody770; bone mineral density measured by VENUS evo), muscle quality (phase angle and extracellular water ratio [ECW/TBW] measured by InBody770), muscle strength (knee extension strength), physical function (chair stand test [CS-30] and Timed Up & Go test)
3) Subjective assessment questionnaires (POMS2, Anti-Aging QOL Common Questionnaire, SCD-Q, and skin-related assessments using visual analog scales (VAS))
4) cold-like symptoms questionnaire
5) Physical function (walking speed and handgrip strength): between-group comparison at 8 weeks; within-group comparison before and after intervention; and change from baseline (delta 8-week value: 8-week value - screening value; delta 16-week value: 16-week value - screening value)
6) Comprehensive gene expression analysis in peripheral blood mononuclear cells (PBMCs) using single-cell RNA sequencing
