""Taken together, our findings provide solid evidence confirming the existence of a gut-muscle axis in which this identified bacterium positively modulates muscle metabolism and muscle strength.""
""Participants with higher grip strength also had greater quantities of a genus of gut bacteria called Roseburia, particularly a species called Roseburia inulinivorans.""
""Older adults that possessed the bacterium demonstrated 29 percent greater grip strength in the tests compared to those that didn't.""
""Younger adults with the bacterium showed higher cardiorespiratory capacity, while older adults had low levels of Roseburia inulinivorans, possibly contributing to muscle loss with age.""
Research indicates that the gut microbe Roseburia inulinivorans is linked to increased muscle strength and fitness. A study analyzed microbiomes of young and older adults, revealing that those with higher grip strength had greater quantities of this bacterium. Older adults with Roseburia inulinivorans exhibited 29% greater grip strength. The findings suggest a gut-muscle axis that could inform probiotic development for combating muscle-wasting disorders and maintaining strength as we age.
