Abstract
Proučavani su radni položaji ruku kakve imaju operateri tokom rada uz videoterminale. Istraživanje je provedeno fotoanalizom i izradom biomehaničkih modela za koje su upotrijebljeni antropometrijski podaci o visini ispitanika i njihovoj ukupnoj tjelesnoj masi. Na temelju prikupljenih podataka određene su mase svih promatranih ispitanika te je formuliran biomehanički model koji odgovara radnim položajima: neutralnom položaju, srednjim radnim položajima i položaju s ispruženim rukama. Ergonomska analiza rada, provedena kvantifikacijom težine položaja ruku za vrijeme rada, upućuje na to da je potrebno uložiti mnogo veći napor kada su ruke ispružene nego kada su u neutralnom položaju.The positioning of the subject\u27s arms during work with video display terminals was observed employing biomechanical model construction based on anthropometric data concerning the subject\u27s height and total body mass. Segmental masses were determined for each subject under study and a biomechanical model corresponding to the working arm positioning, i.e. to the neutral position, medium working position and the position with arms stretched out, was formulated. Ergonomic work analysis, realized by quantifying the work weight based on arm position during work showed that more effort is required with the arms stretched out than in the neutral position
