[目的]日常运动中的运动轨迹与环境属性相关的信息密切相关。在背坐任务的情况下，它可以根据椅子属性而变化。本研究的目的是调查健康成年人在背坐任务中的轨迹形成是否取决于座位宽度信息。[对象和方法] 10名健康男性青年在5种座椅宽度条件（80%、90%、100%、110%和120%）下进行仰卧起坐任务。运动分析系统和测力板的采样频率设定为250 Hz。 计算空间和时间变量以检查座位宽度的影响。还进行了问卷调查，以检查参与者是否意识到每个座位的宽度相比，他们自己的宽度窄或大。[结果]调查结果显示，多数被调查者知道自己的体型与座椅宽度的相对比较，但也有部分被调查者不知道。然而，空间和时间变量是不变的，在不同的座位宽度条件下。[结论]健康成年人在日常情境变化的情况下，背-坐任务的轨迹形成不依赖于对座位宽度信息的感知。
[Purpose] The movement trajectory in daily motion is strongly associated with information regarding the properties of the environment. In the case of the back-to-sit task, it may vary according to chair property. The purpose of this study was to investigate whether trajectory formation in back-to-sit tasks by healthy adults depends on seat width information. [Participants and Methods] Ten healthy young males performed a back-to-sit task in 5 seat width conditions (80%, 90%, 100%, 110%, and 120% of each participant’s buttock breadth). The motion analysis system and force plates were set at a sampling frequency of 250 Hz. The spatial and temporal variables were calculated to examine the effect of seat width. A questionnaire was also administered to examine whether the participants were aware of each seat width in comparison with their own buttock breadth as narrow or large. [Results] The questionnaire results showed that many participants were aware but some were unaware of the relative comparison of their size to the seat width. Nevertheless, the spatial and temporal variables were invariant under the different seat width conditions. [Conclusion] In healthy adults, the trajectory formation in back-to-sit tasks is not dependent on the perception of seat width information under their variability as per daily situations.
