Bidirectional relationship between gut microbiome and exercise performance and recovery: a narrative review
Mach N, Fuster-Botella D
Evidence is still limited and needs further study
Summary
A narrative review on the bidirectional interaction between the gut microbiome and exercise performance and recovery. Regular exercise increases gut microbiome diversity, while optimal gut flora may support exercise performance and recovery. The review highlights the role of short-chain fatty acid-producing bacteria and potential benefits of probiotic supplementation.
Key findings
- 1
Regular aerobic and resistance training increases gut microbiome diversity
- 2
Short-chain fatty acid (SCFA: butyrate, propionate) producing bacteria are involved in energy supply and inflammation control
- 3
Probiotic supplementation (Lactobacillus spp.) reportedly reduces upper respiratory tract infections and GI symptoms
- 4
Gut microbiome research in athletes is advancing but causal relationships require further investigation
