Healthy Gut = Immune Defense and Barrier function
1.5 kg bacteria(10 to the 13th)
> than 160 species per person
Prebiotics:
dietary fiber
Polyphenols
N-3 Fatty Acids
Challenges to gut during exercise:
HYPOXIA
Decrease in barrier function = leaky gut leads to inflammation
– degradation of tight junctions
-mild endotoxemia
-leaky gut
-inflammation
HEAT EXASPERATES THIS
Increase in T-Lymphocytes and Leukocytes
Single strain supplementation no response
Multi strain supplementation less than 6 weeks, no response
Multi Strain supplementation 12-14 weeks evidence maybe
Lactobacillus
Bifobacterium both decrease inflammation and Ph
Bifo: decreases zonulin = decrease in tight junction degradation
**12 weeks of multistrain in endurance athletes decreases incidence of respiratory tract infections
