Problems of determination of rest allowances Part 2: determining rest allowances in different human tasks.

Within a task analysis related to strain on the individual, human tasks can be ordered into five steps differentiated by the various strains on human organs using different capabilities. For these five categories, examples of rest allowances based on laboratory as well as field study research using physiologically oriented methods are given. Different types of breaks are discussed and suitable measures for optimizing rest allowances are mentioned.
