Repetitive work in occupational settings often requires a combination of mental and physical demands, but few studies were conducted concerning the relationship between attention and repetitive work. In attentive and cognitive tasks, it is common to observe effort and fatigue without the presence of those neuromuscular modifications that would justify the use of these terms. Therefore, we can talk about mental fatigue in those cases in which it is observed the exhaustion of the necessary resources for the execution of a job that doesn't demand the employment of neuromuscular apparatus. ⋯ The European Community has often emphasized the pathogenic value of stress and fatigue with their high social and individual costs. For this purpose, it is opportune to consider the norm UNI EN ISO 10075, which points out the necessity to consider the human component, in term of mental load which implies not only the cognitive component but also the whole psychical sphere of the subject. Training intended like a sort of learning of specific modalities, supplies workers with the necessary instruments for a correct and more aware management of the peculiarities of working activity, contributing to the reduction of fatigue and stress deriving from the job.
