impacts a person’s quality of life. Recent studies to improve muscle function through the intake
of various functional food materials are attracting attention. However, it is not yet known
whether probiotics can improve muscle mass and muscle strength and affect physical performance.
Lactobacillus plantarum HY7715 (HY7715) is a lactic acid bacteria isolated from kimchi. The present
research shows that L. plantarum HY7715 increases physical performance and skeletal muscle mass
biogenesis but also inhibits the sarcopenic process in skeletal muscle. In addition, HY7715
recovers the microbiome composition and beta-diversity shift. Therefore, HY7715 has promise as a
functional probiotic supplement to improve the degeneration of muscle function that is associated
