在不限制腿部运动的情况下，连续站立和坐着工作时腿部肿胀：Akihiko Seo等。为了明确站立和坐着工作时腿部肿胀的动态，在不限制腿部运动的情况下，测量了三种工作条件下的小腿肿胀和主观抱怨：直站、坐臀部椅和坐普通椅子。12名受试者（8名男性和4名女性）被分配了一个小时的拼图任务。每2分钟记录一次小腿肿胀和主观主诉。采用生物电阻抗法测量下肢肿胀。结果表明：(1)在所有工况下，小腿肿胀均呈增加趋势。直站时肿胀最小，坐普通椅子时肿胀最大。直立站立1小时后腿部肿胀的均值和标准差为5.8±3.9%，坐臀椅组为8.2±4.7%，坐普通椅组为9.7 + 7.5%。(2)工作过程中的主观抱怨也有所增加。坐在普通椅子上抱怨小腿麻木的人最少，站直的人抱怨最多。与腿部肿胀的关系是相反的。与其他工作姿势相比，坐臀部椅的人更常抱怨腰痛。长时间站立比坐着更容易引起腿部肿胀，这是合理的，因为高静水压力。这一理论得到了对静止站立和坐姿的研究的支持。然而，我们在不限制腿部运动的情况下获得的结果显示出相反的关系。研究认为，尽管静水压力较站立姿势低，但坐姿的腿部肿胀因素，如肌肉活动和淋巴泵低、肌肉活动导致的间质压力低、久坐时的座位压力等，可能是主导因素。
Leg Swelling during Continuous Standing and Sitting Work without Restricting Leg Movement: Akihiko Seo, et al. Department of Public Health, Hiroshima University School of Medicine—To clarify the dynamics of leg swelling during standing and sitting work without restricting leg movement, lower leg swelling and subjective complaints were measured during work under three working conditions: Straight standing, buttock chair sitting and ordinary chair sitting. Twelve subjects (eight males and four females) were assigned jigsaw puzzles as a task for an hour. The lower leg swelling and subjective complaints were recorded every two minutes. The lower leg swelling was measured by the bioelectrical impedance method. The results were as follows: (1) The lower leg swelling increased during the work under all working conditions. The swelling was least for straight standing and greatest for ordinary chair sitting. The mean and standard deviations for leg swelling after one hour's work were 5.8±3.9% for straight standing, 8.2±4.7% for buttock chair sitting and 9.7 + 7.5% for ordinary chair sitting. (2) The subjective complaints also increased during work. Complaining of lower leg dullness was least for ordinary chair sitting and greatest for straight standing. The relation to the leg swelling was reversed. Complaining of low back pain was more common for buttock chair sitting than for other working postures. It is reasonable that prolonged standing is more likely to cause leg swelling than sitting because of high hydrostatic pressure. This theory has been supported by studies on motionless standing and sitting. Our results obtained without restricting leg movement, however, showed a reversed relation. It was considered that leg swelling factors such as low muscle activity and lymph pumps, low interstitial pressure brought on by low muscle activity, and the seat pressure during prolonged sitting may be dominant in the sitting posture although the hydrostatic pressure was low compared with the standing posture.
