title: [Variations in body height within the course of a working day].
abstract: Variation of body height during the day has been analyzed considering the influence of various occupations (standing, sitting, mixed) on the posture. In addition to this the following variables have been recorded on the 302 individuals under study: Sex, age, working time, time of getting up in the morning, kind of occupation, physique, sporting activities in the leisure-time, presence of defects of the spinal column, possibility of changes of the carriage at the working place and extensibility of the spinal column. The statistical analysis showed that with the exception of pathological alterations of the spinal column all these variables are influencing the variation of body height during the day. It could also be shown that the extensibility of the spinal column does not vary during the day. The author is discussing also ergonomical rules concerning the organization of working places for standing and sitting occupations. Finally some recommendations for the future organization of such places are given.
