Definição de parâmetros para o estudo da fadiga muscular em exercĂcios dinâmicos utilizando a metodologia acumulativa-normalizada por meio de eletromiografia
Dissertação (mestrado)—Universidade de BrasĂlia, Faculdade de Tecnologia, Departamento de Engenharia ElĂ©trica, 2018.Esta dissertação compreende o estudo da fadiga muscular, e aborda a determinação de parâmetros que possibilitem a avaliação objetiva da fadiga muscular em esforços fĂsicos dinâmicos utilizando EMG-S (eletromiografia de superfĂcie). O trabalho tem enfase na busca que parâmetros que permitam a repetibilidade da avaliação em diferentes voluntários e diferentes tipos de esforços fĂsicos. AlĂ©m de Ăndices indicadores de fadiga já consolidados na literatura, usar-se-á um indicador demostrado pelo grupo de pesquisa da Universidade de BrasĂlia, que mostrou bastante eficácia e sensibilidade quanto Ă evolução da fadiga muscular. Tanto para este parâmetro quanto para os outros abordou-se, alĂ©m da verificação direta dos indicadores uma análise com indicadores acumulativos. As avaliações realizadas mostraram que, ajustando os parâmetros de processamento de sinais flexivelmente de acordo com cada sinal, tanto os novos quanto os parâmetros clássicos se mostram tĂŁo promissores na análise de exercĂcios dinâmicos como já observado na análise de exercĂcios isostáticos. Os modelos determinantes de indicadores de fadiga atravĂ©s de EMG-S mostraram um grau de reprodutibilidade alvissareiro em relação a diferentes pessoas, diferente exercĂcio e diferentes mĂşsculos de estudo.This work comprises the study of muscle fatigue and addresses the determination of parameters that allow the objective evaluation of muscle fatigue in dynamic physical efforts using EMG-S(surface electromyography). The work focuses on the search for parameters that allow the repeatability of the evaluation in different volunteers and different types of physical efforts. In addition to indexes of fatigue already consolidated in the literature, an indicator will be used, demonstrated by the research group of the University of BrasĂlia, which showed a great deal of efficacy and sensitivity regarding the evolution of muscular fatigue. For both this parameter and the others, it was approached, besides the direct verification of the indicators, an analysis with cumulative indicators. The evaluations showed that by adjusting the signal processing parameters flexibly according to each signal, both the new and the classical parameters are shown as promising in the analysis of dynamic exercises as already observed in the analysis of isotactic exercises. The determinant models of fatigue indicators through EMG-S showed a degree of reproducibility in relation to different people, different exercise and different study muscles
Epidemiological data of patients diagnosed with COVID-19 in the municipality of Gurupi, Tocantins
According to the World Health Organization (WHO), COVID-19 is a viral disease transmitted from person to person, which has the fastest spread in the world. OBJECTIVE: This project aimed to analyze epidemiological aspects of COVID-19 in the municipality of Gurupi/TO. METHODOLOGY: The research was conducted by consulting the epidemiological bulletin of COVID-19 made available daily by VISAE, from March 16, 2020, to May 15, 2021, where we identified the evolution of positive cases, deaths, and gender identification of this population, and analysis of literature review on the subject. RESULTS: Of the 10,336 positive cases, 5,570 (53.89%) of the cases are female, 194 (7.13%) evolved to deaths, of these 70 (36.08%) were female and 124 (63.92%) were male. FINAL CONSIDERATIONS: From the results, it is visible the reduction in the numbers of positive cases for COVID-19 from April 2021, which can be taken into consideration the measures adopted through the Municipal Decrees, and in part to the beginning of the immunization process. Thus, the continuity of prophylaxis measures is essential for the control of the high chain of transmission in the municipality
