Risks of Resistance Training for the Bruxism: a Cross-Sectional Study

Objective: Evaluate the association between anxiety, sleep and awake bruxism in volunteers that practice resistance training. Methods: One hundred and two volunteers answered four questionnaires: checklist of oral behaviors to diagnostic the awake bruxism, international classification of sleep disorders to identify sleep bruxism, generalized anxiety disorder 7 (GAD-7) which checks levels of anxiety symptoms and characterization of resistance training (reason, frequency, periodicity and period of training, as well as the perception of orofacial pain or clenching during training). A descriptive analysis, Pearson's and Tukey test (α = 0.05) was made. Results: Dental clench during training and the perception of orofacial pain after this activity had a significant association (ρ = 0.36; p < 0.001). The extensive resistance training (ρ = 0.30; p = 0.005) and the frequency of training (ρ = 0.40; p > 0.001) also influenced the perception of pain. The diagnostic of sleep and awake bruxism proved to be associated (ρ = 0.36; p <0.001). Sleep bruxism was also associated with higher levels of anxiety symptoms. (ρ = 0.36; p = 0.002). The other variables showed no statistical association. Conclusion: It is concluded that the active adult population participating in this study has inadequate knowledge about functional foods, which are not included in their usual diet.
