Oral microbiome analysis of elite race walkers in response to different dietary patterns.

We examined the oral microbiome of highly-trained endurance race walkers to determine how dietary interventions might affect these communities and any possible links to metabolism and performance of exercise.Saliva samples were collected before and after a three-week period of intensified training with dietary interventions of either a ketogenic Low Carbohydrate High Fat (LCHF), High Carbohydrate (HCHO) or Periodised Carbohydrate (PCHO) diet. Genomic DNA extracted from these samples was used to construct amplicon libraries of the 16S rRNA gene from Bacteria/Archaea.
