Investigação eletromiográfica de músculos da mastigação entre indivíduos da terceira idade sedentários e praticantes de atividades físicas aeróbica e anaeróbica.

Abstract

Introduction: the elderly population has increased worldwide due to the evolution of science, which allows a healthy aging and the practice of aerobic and anaerobic exercise. By practicing physical exercises, the elderly tend to increase muscle mass and decrease bone loss, among other positive factors for the practitioner. The muscles, larger agents of movements, work together and collaboratively, both for static posture and in dynamic situations. When you have a frequent practice of physical activities, the postural muscles acquire tone and effect. In the case of the atlanto occipital joint, the cervical region is better stabilized by adjusting to the position of the head and, consequently, optimizing the action of the masticatory muscles, harmonizing the whole locomotor systemic stomatognathic apparatus. Objective: investigate the possible influences of aerobic and anaerobic exercise on masticatory efficiency. Methodology: To this end, 15 female volunteers participated, aged 60 or more years, practitioners of physical activity, aerobic, anaerobic and sedentary. In each volunteer, through the electromyograph, was collected and analyzed the RMS (Root Mean Square) in the moments of rest, maximum intercuspation and chewing. Result: the RMS (Root Mean Square) results of each volunteer group were compared, obtaining no significant difference at rest, however, at the moment of maximum intercuspation and mastication there was greater muscular electrical activity in the group of aerobic volunteers, then anaerobic and, finally, the sedentary ones. Conclusion: there is a relation of the electrical activity of the masseter muscle with the practice of physical exercises.
