| 摘 要： | 目的：研究在身体不同部位的计步器（手腕、腰部和鞋中底）在步行、慢跑和上下楼梯时记录步数的准确性和可靠性。方法：20名受试者按照实验要求以自我选择的速度依次在400m塑胶跑道上进行步行和慢跑以及上下总共17层的楼梯共10次。所有的步数通过计步器和摄像机记录。一周后所有受试者人员重复上述测试，只记录计步器数据。结果：在步行时，腰部和鞋中底的计步器的精确性显著性的高于腕部（p < .05）。在慢跑和上下楼梯时，鞋中底的计步器的精确性显著性的高于腕部（p < .05）。计步器放置于腰部和鞋中底都表现为较小的相对误差值（<3%）。在慢跑和步行时，放置于所有位置的计步器都表现为较高的可靠性（alpha>0.80）。结论：在慢跑和上下楼梯时，计步器的精确性并不受到放置位置的影响，但是上下楼梯时无论放置在任何身体位置都未达到高度可靠性。综合所有情况，在鞋中底嵌入计步器可能是用以记录人体日常活动情况最佳选择。

| Abstract: | Objective: This investigation aims to explore the accuracy and reliability of pedometers placed in different positions on the body (wrist, waist, and in-shoe) during walking, running and stair walking. Methods: Twenty healthy adults were required to walk and run the 400 m around the outdoor track, and continuous ascended and descended 17 short flights of stairs for ten times at a consistent self-selected speed. All the steps were recorded by the pedometers and video (gold standard). This procedure was repeated at the same time one week later without a video record. Results: Waist- (p < .05) and in-shoe-worn (p < .05) pedometer''s accuracy was significantly higher than wrist-worn during walking, and in-shoe-worn higher accuracy than wrist-worn both running (p < .05) and stair walking (p < .05). The MAPE of the pedometers placed on the waist and in-shoe were small MAPE (<3) during all locomotion. The intramodel reliability was exceptionally high (>0.80) when wearing all positions during walking and running. Conclusions: The pedometer''s position does impact the accuracy of step count for running and stair walking. The in-shoe-worn might an accurate and reliable way to assess physical activity in daily life. |
