Antibiotics, Gut Microbiome, and the Exercise Connection — Dr. Sara Campbell — #390

About this episode

In this episode of the Flex Diet Podcast, I sit down with Dr. Sara Campbell, Ph.D., Associate Professor at Rutgers University, for a conversation about the bidirectional relationship between exercise and the gut microbiome.

Dr. Sara Campbell returns to discuss her lab's cutting-edge research on the bidirectional relationship between exercise and the gut microbiome — including why consumer gut tests oversimplify a complex ecosystem, how antibiotics devastate exercise capacity in animal models, and why single-microbe probiotics miss the bigger picture of functional guilds. She also shares new findings on short-chain fatty acids, amino acid metabolomics after antibiotic treatment, and the emerging neuromuscular junction hypothesis.

In this episode you'll learn:

  • Why consumer gut microbiome tests are misleading and what functional guilds tell us instead
  • How antibiotics devastate exercise capacity and the surprising metabolomic changes they cause
  • The current evidence on probiotics for exercise performance and why single strains fall short
  • What short-chain fatty acids do for gut health and exercise, and the emerging neuromuscular junction hypothesis
