The Influence of Endurance Sports Activity on the Oral Microbiota of Young Adults.

Analysis of the oral microbiota in healthy individuals engaged in endurance physical activity at different levels.

The oral cavity is an easily accessible anatomical site that accurately reflects the health
 of the individual. The mouth is considered an early indicator of biological aging, leading to
 the identification of oral biomarkers predictive of future alterations. Current data show
 that the oral health of high level athletes is globally altered with an increase in
 cariogenic indexes, an increased incidence of periodontitis, dental trauma and dry mouth
 syndromes. Few studies have focused on the oral microbiota compared to mouthguards used in
 rugby or boxing which seem to induce dysbiosis, a recent study shows an effect of ketogenic
 diet on bacterial changes in the mouth of endurance athletes. This project focuses on the
 impact of intensive sport practice on oral health and the identification of oral biomarkers
 associated with physical activity. The objective of this study is to investigate the impact
 of the amount of endurance sport practice on oral microbiota and oral health in young adults.
 the hypothesis is that a sedentary lifestyle and high-level sport induce depletion and/or
 changes in the oral microbiota compared to regular physical activity.
