Resumo: The main objective of this research was the assessment of the physical workload of farm coffee workers from southern Minas Gerais, Brazil. Twelve workers were reconded and their heart rate monitored during one hour execution of five different tasks, both on flat and sloping ground. The assessment of body postures adopted and the actions performed were achieved through the “Captiv” software. We attempted to correlate the results of the assessments and interpret them in the light of the observation of the activities of the workers. The most significant cardiovascular demands occurred in subtasks of foliar and manual fertilization, classifying them as moderate work. Harvesting and thinning were the subtasks that appeared to have the greatest variability of postural combinations: the harvest due to the variety of operating actions; the thinning, although only one relevant operational action, due to the very nature of the task. Either the cardiovascular or the biomechanical indicators revealed no statistically significant differences between the subtasks carried by workers in conditions of flat and sloping ground.

Doze trabalhadores foram filmados e sua frequência cardíaca foi monitorada durante uma hora na execução de cinco diferentes tarefas, ambas em condições de terreno plano e em declive. Foram avaliadas as combinações posturais adotadas através do software “Captiv”. Buscou-se correlacionar os resultados das avaliações e interpretá-los à luz da observação das atividades dos trabalhadores. As cargas cardiovasculares mais elevadas ocorreram nas subtarefas de adubação foliar e adubação a lanço, classificando-as como trabalho moderado. A colheita e a desbrota foram as subtarefas que apresentaram maior variabilidade de combinações posturais: a colheita devido à variedade de ações operacionais; a desbrota, apesar de uma única ação operacional relevante, por conta da própria natureza da tarefa. Tanto os indicadores cardiovasculares, como os biomecânicos não revelaram diferenças estatisticamente significativas entre as subtarefas desenvolvidas pelos trabalhadores, em condições de terreno plano e em declive.2015-02-132017-08-01T20:06:54Z2017-08-01T20:06:54Z2005info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfBARBOSA, M.
