Avaliação da carga de trabalho físico e análise biomecânica de trabalhadores da carbonização em fornos tipo "rabo-quente" Emília Pio da Silva Manoel Marques de Faria Luciano José Minette Alexandre Santos Pimenta Amaury Paulo de Souza Nilton César Fiedler Agrociencias Ergonomia freqüência cardíaca e lesão Este estudo teve como objetivo principal avaliar a carga de trabalho físico e a análise biomecânica de 20 trabalhadores da carbonização em fornos tipo rabo-quente, localizados no Norte do Estado de Minas Gerais. Para análise da freqüência cardíaca, foi utilizado o sistema Polar Eletro Oy da Finlândia. O tempo consumido pelos trabalhadores por atividade foi avaliado através do método de cronometagem individual e a análise biomecânica, realizada por programa computacional desenvolvido pela Universidade de Michigan. Os resultados evidenciaram que a carga cardiovascular exigida para a realização da atividade era de 44,5% e classificada como moderadamente pesada. A operação que mais consumia tempo de trabalho era a vedação. Havia risco de compressão no disco vertebral L5 S1 na operação de carga, durante as fases de levantamento da rede e remoção de tora. 2007 artículo científico 0100-6762 https://www.redalyc.org/articulo.oa?id=48831509 pt http://www.redalyc.org/revista.oa?id=488 Revista Árvore application/pdf Universidade Federal de Viçosa Revista Árvore (Brasil) Num.5 Vol.31
