- On the basis of a literature study a hypothesis was put forward, claiming that swelling of the lower legs during prolonged sedentary work increases the risk of peripheral venous disorders in the legs. Thus, swelling of the left lower leg during sitting has been studied. The aim, was to examine the effect of rest pauses involving leg movements. In a field study three healthy women performed light work for eight hours while sitting on standard office chairs adjusted according to lower leg length. In all, the study comprised nine normal and nine experimental days. On the normal days the subjects sat all the time except for lunch and for two coffee breaks. During the experimental days the subjects were required in addition to take a two-minute walk every fifteen minutes. A lower leg swelling of 3.4-5.5% was observed during the normal days, and 1.8-2.7% during the experimental days. Additionally, the subjects experienced less discomfort in the left lower leg during the experimental days. In a laboratory study two healthy women sat relaxed for one hour each. Changes in the volume of the lower leg were measured. At various intervals the lower leg was exercised for one minute. For all intervals and in all tests this caused an elimination of the swelling accumulated during the previous period of relaxed sitting.
