ALVES, José Urbano et al. Biomechanical evaluation of activities of Eucalyptus ssp. seedling production. Rev. Árvore [online]. 2006, vol.30, n.3, pp.331-335. ISSN 1806-9088. http://dx.doi.org/10.1590/S0100-67622006000300002.
This study was based on data collected in a nursery located in the municipality of Rio Doce, MG, to evaluate the biomechanics of activities of Eucalyptus spp seedling production. The evaluation was carried out by the bidimensional analysis with the use of the videotape recording technique, with the images of movements frozen to measure the angles of the several body segments. The involved forces were measured in order to apply the biomechanical bidimensional model for the prediction of postures and static forces, using a software developed by the University of Michigan, US. The seedling transport with a pushcart was the only activity presenting compression force on the spinal disc above the superior load limit; and all the studied activities surpassed the load limit recommended in at least one phase of the cycle and in at least one articulation.
