Exercise increases gut microbiota biodiversity and the abundance of health-promoting taxa (e.g., Akkermansia, Faecalibacterium), which correlates with better physical performance and muscle function.
Regular physical activity, especially resistance and aerobic training, naturally improves your gut bacteria diversity. This helps your muscles work better and recover faster, adding to the direct benefits of exercise.
ModerateSupportsMEDIUM confidence
Exercise can promote these changes synergistically with diet... Exercise-induced modifications of gut microbiota... including the expansion of taxa such as Faecalibacterium, Clostridium, and Allobaculum... athletes showed a significantly higher microbiome biodiversity.
Why this rating
Based on observational studies in athletes and animal models; limited direct evidence in sarcopenic elderly.

More from this paper
- Gut microbiota acts as a mediator between nutrition and skeletal muscle function (the 'gut-muscle axis'), where bacterial metabolites such as short-chain fatty acids (SCFAs) and urolithins influence muscle anabolism, mitochondrial biogenesis, and inflammation.Moderate
- Short-chain fatty acids (SCFAs), particularly butyrate, produced by gut bacteria (e.g., Faecalibacterium, Butyricimonas) promote skeletal muscle mitochondrial biogenesis, insulin sensitivity, and prevent muscle protein catabolism.Moderate

- Regular physical activity (at least 150 minutes/week of moderate-intensity) reduces all-cause and cardiovascular mortality by 20-30% and lowers the risk of type 2 diabetes by 25-35%.Strong

- Resistance exercise is the only intervention capable of consistently restoring muscle function and strength in sarcopenia, partially overcoming age-related anabolic resistance.Strong
