Summary
This study examined the salivary pH, salivary lactate, and salivary IL-1β responses from a high-intensity intermittent running test, and the influence of hygiene oral status on these biomarkers in elite adolescent basketball players. Forty-six adolescent players participated. Saliva sampling was taken before and 3 min after a high-intensity exercise (Yo-Yo Intermittent Recovery Test Level 1; Yo-Yo IR1). In order to quantify and classify the oral hygiene level, the athletes were submitted to a dental examination, and an adapted Simplified Oral Hygiene Index was applied. After the dental examination, the whole group was divided into good oral hygiene group (GHG) and poor oral hygiene group (PHG). The results of a twoway analysis of variance showed a significant interaction effect (P = 0.0003), group effect (P < 0.0001), and time effect (pre to post Yo-yo IR1; P < 0.0001) for salivary pH and for salivary lactate (interaction effect, P = 0.008; group effect, P < 0.0001; time effect, P < 0.0001) with a lower salivary pH and a higher salivary lactate at pre and post-Yo-Yo IR1 for PHG, but no difference was observed for IL-1β. The data demonstrated that the high-intensity exercise led to a significant change in salivary pH and salivary lactate concentration of the basketball players, and that the oral hygiene status influenced these responses, with a greater change for those players showing a poor oral hygiene.
