The purpose of this study was to examine the previous researches on position change. The results of the study were follows ; (1) hemodynamic parameters show difference immediately after the position change and tend to the original data in 15 minutes. (2) the difference of hemodynamic parameters is caused by the temporary decrease of venous return. The purpose of the study in second year was to investigate physiological effect of position change. This quasi-experimental study measured calf muscle blood flow of 15 healthy adults by near-infrared spectroscopy (NIRS). Besides, the level of position change was measured by accelerometer with the same subjects. Transient change of the calf muscle blood flow in ΔO2Hb and ΔHHb occurred after position change in all subjects. The further analysis is needed to elucidate the relationship between calf muscle blood flow and the level of position change.

这项研究的目的是检查先前关于位置变化的研究。遵循了研究的结果； （1）血液动力学参数在位置变化后立即显示出差异，并在15分钟内倾向于原始数据。 （2）血液动力学参数的差异是由静脉回流的暂时减少引起的。该研究在第二年的目的是研究位置变化的身体影响。这项准实验研究通过近红外光谱（NIR）测量了15位健康成年人的小腿肌肉血流。此外，位置变化的水平是通过具有相同受试者的加速度计测量的。所有受试者位置变化后，ΔO2HB和ΔHHB中小腿肌肉血流的短暂变化发生。需要进一步的分析来阐明小腿肌肉血流与位置变化水平之间的关系。
