#PTonICE Podcast Episode 1923 - The role of exercise in the gut microbiome & aging
4 snips
Feb 26, 2025 Discover the intriguing link between exercise and gut health, especially in older adults. A systematic review highlights how physical activity influences the gut microbiome, essential for nutrient absorption and metabolic processes. Key metabolites like short-chain fatty acids and B vitamins are crucial for maintaining health and regulating glucose levels. The conversation emphasizes the need for more research to pinpoint the best exercises for gut microbiome support as we age.

Episode notes
Gut Microbiome Functions
- The gut microbiome regulates metabolic processes, nutrient absorption, and inflammatory responses.
- Key metabolites include short-chain fatty acids (glucose balance), bile acids (fat digestion), and B vitamins (energy, brain function).
Aging and the Gut
- The gut microbiome shifts with age, increasing inflammatory agents and reducing micronutrient absorption.
- These shifts are linked to age-accelerating conditions like diabetes, obesity, and cardiovascular disease.
Exercise and Gut Health
- Exercise affects gut bacteria, increasing beneficial and reducing harmful bacteria.
- Studies show inconsistencies in specific bacteria changes, but the overall trend links exercise to improved gut, metabolic, and overall health.
