The association between the gut microbiome and sarcopenia remains poorly understood. This systematic review aims to evaluate the relationship between muscle parameters and the intestinal microbiome. A systematic search was conducted in PubMed, EMBASE, Cochrane Library, and Google Scholar for studies published between 2002 and 2022 involving participants aged 50+. Studies were included if they assessed sarcopenia using at least one measure of muscle mass (skeletal muscle mass, bioelectrical impedance analysis, MRI), muscle strength, or muscle performance (SARC-F questionnaire, Timed-Up-and-Go Test, Chair Stand Test, grip strength, gait speed, Short Physical Performance Battery, 400 m Walk Test). The microbiome was measured using at least RNA\/DNA sequencing or shotgun metagenomic sequencing. Twelve studies were analyzed. Findings revealed that a higher abundance of bacterial species such as Desulfovibrio piger, and Clostridium symbiosum and reduced diversity of butyrate-producing bacteria was associated with sarcopenia severity, as indicated by decreased grip strength, muscle mass, or physical performance. The gut microbiome plays a significant role in age-related muscle loss. Probiotics, prebiotics, and bacterial products could be potential interventions to improve muscle health in older adults.<\/jats:p>","DOI":"10.3390\/ijerph21091246","type":"journal-article","created":{"date-parts":[[2024,9,20]],"date-time":"2024-09-20T10:49:48Z","timestamp":1726829388000},"page":"1246","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Association of Gut Microbiome with Muscle Mass, Muscle Strength, and Muscle Performance in Older Adults: A Systematic Review"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-7685-1944","authenticated-orcid":false,"given":"Martin Hubert","family":"Mayer","sequence":"first","affiliation":[{"name":"Karl Landsteiner University of Health Sciences, 3500 Krems an der Donau, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-7632-7389","authenticated-orcid":false,"given":"Selam","family":"Woldemariam","sequence":"additional","affiliation":[{"name":"Karl Landsteiner Institute for Health Promotion Research, 3062 Kirchstetten, Austria"},{"name":"Center for Public Health, Department for Social and Preventive Medicine, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph","family":"Gisinger","sequence":"additional","affiliation":[{"name":"Academy for Ageing Research, Haus der Barmherzigkeit, 1160 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5218-1160","authenticated-orcid":false,"given":"Thomas Ernst","family":"Dorner","sequence":"additional","affiliation":[{"name":"Karl Landsteiner Institute for Health Promotion Research, 3062 Kirchstetten, Austria"},{"name":"Center for Public Health, Department for Social and Preventive Medicine, Medical University of Vienna, 1090 Vienna, Austria"},{"name":"Academy for Ageing Research, Haus der Barmherzigkeit, 1160 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,20]]},"reference":[{"key":"ref_1","unstructured":"European Commission (2011).
