Abstract

Physical activity is an important impact factor in overall health and the lack of it is one of the causes of chronic diseases such as hypertension, type 2 diabetes and obesity. However, with the largest access of population to information and influences on a healthier lifestyle, the demand for habits such as healthy eating and sports has increased considerably, seeking not only health but also aesthetics. For this, many individuals practice the hypertrophic training, a type of exercise that seeks the increased volume of muscles through training with high load strength. In view of the large muscular effort made in this practice, it is necessary to evaluate possible relationships between hypertrophic training and the muscles of the stomatognathic system. The aim of this study is to evaluate the influence of hypertrophic physical activity in masticatory efficiency, maximum bite force and electrical activity of the masseter and temporalis muscles. It will be selected 20 individuals (10 men and 10 women) who practice regular hypertrophic physical activity according to the criteria of inclusion and exclusion pre-established. Then, it will be performed a data collection of demographics and initial analysis of masticatory efficiency, maximum bite force and electromyographic analysis of masseter and temporal muscles. It will be performed a standardized hypertrophic training predetermined by the physical educator, and right after training, all analyzes will be repeated. The data will be submitted to normality test, and for statistically significant differences, the appropriate probability test will be applied, and if possible, correlation tests. (AU)
