What this Trial Is About
Purpose: This clinical trial aims to evaluate the efficacy and safety of Lactiplantibacillus plantarum LM1001 in improving muscle strength in older adults. The study is designed to investigate its potential effects on muscle strength based on the gut-muscle axis. Methodology: This study is a randomized, double-blind, placebo-controlled, single-center clinical trial. A total of 100 participants will be enrolled and randomly assigned to either the test group (n=50) or the placebo group (n=50). Participants in the test group will receive 500 mg of Lactiplantibacillus plantarum LM1001 (1.0 × 10¹⁰ CFU/day) once daily for 12 weeks, while those in the placebo group will receive a matching placebo. Key Outcome Measures: To evaluate the effects on muscle strength, the following parameters will be assessed at baseline and after the 12-week intervention period: \- Primary Outcome Measures: Changes in isokinetic knee extension and flexion strength. \- Secondary Outcome Measures: Changes in muscle strength-related parameters, including muscle power, skeletal muscle mass (SMM), and skeletal muscle mass index (SMI), as well as physical performance measures such as handgrip strength, Short Physical Performance Battery (SPPB) score, Timed Up and Go (TUG) test, and health-related quality of life assessed by EQ-5D-5L. \- Safety Assessments: Safety will be evaluated based on the incidence of adverse events, serum biochemical parameters, and clinical laboratory test results.
