Este trabalho teve por objetivo realizar uma avaliacao biomecânica de trabalhadores nas atividades de poda em plantios de Pinus taeda L., visando a melhoria das condicoes de conforto, seguranca e saude. Os dados foram coletados em uma empresa prestadora de servicos localizada na regiao do Norte Pioneiro, estado do Parana, Brasil, sendo estudadas as atividades de primeira, segunda e terceira podas pelos metodos manual e semimecanizado. Para a avaliacao biomecânica, foram realizadas filmagens dos trabalhadores na execucao do trabalho, sendo os dados analisados nos programas WinWoas (Sistema de Analises de Posturas no Trabalho) e 3DSSPP (Programa de Predicao de Postura e de Forca Estatica 3D). Os resultados mostraram que as posturas adotadas pelos trabalhadores foram consideradas normais, sem a necessidade de adocao de medidas ergonomicas corretivas. A postura dos trabalhadores em alguns momentos, com os bracos estendidos acima do nivel dos ombros, na execucao da poda manual, mostrou a necessidade de ajuste no cabo da ferramenta, evitando problemas futuros a saude. Nao houve compressao no disco L5-S1 da coluna vertebral, porem verificou-se um maior esforco causado pelo metodo manual com o aumento da altura das podas. O quadril foi a articulacao mais afetada, porem sem causar danos a saude dos trabalhadores. Palavras-chave: Biomecânica; poda; saude; ergonomia. Abstract Biomechanic evaluation of workers at the manual and semimechanized pruning activities in Pinus taeda. This research aimed to execute biomechanical evaluation of workers at pruning activities in  Pinus taeda L. plantations, in order to improve  comfort, safety and health conditions. The data were collected at a forest service company, located in the Pioneer Northern, Parana State, Brazil; it was focused first, second and third pruning activities by manual and semimechanized methods. In order to improve biomechanical evaluation, workers were filmed during their activities and the data submitted to the OWAS (Working Postures Analysing System) and 3DSSPP (Prediction of Static Force Posture 3D) programs. Results revealed that postures adopted by workers were considered normal, with no necessary corrective ergonomic actions. In some moments posture adopted by workers, arms extended above their shoulder level in the manual pruning, pointed to a necessary adjust of cable pruning saw, in order to avoid future health problems. There wasn´t compression on L5-S1 column disc, however, it was identified that higher stress is caused by manual method as increase the pruning height. The hip was the articulation most affected, but not causing damage to workers' health. Keywords: Biomechanics; pruning; health; ergonomic.
