背景资料：本研究旨在分析低成本Xiaomi Mi Band 4（MB4）健身追踪器在自由生活条件下与步数和心率相关的有效性和准确性。方法：46名健康志愿者（38.65 ± 14.36岁）参加本次研究。MB4与实验室条件下的视频记录进行了比较，还与自由生活条件下的Sense Wear和Firstbeat监视器进行了比较。结果如下：在实验室方案中，在低速和高速行走时，器械之间的步数没有显著差异。对于自由生活的条件下，MB4表现出较高的收敛效度值在休息和行走的情况下记录期间与Firstbeat监视器。此外，在24小时记录期间，在中速和爬楼梯时，MB4显示了与Sense Wear监测器的适当收敛有效性值。结论：MB4的准确度和精密度是合理的，可以用于监测自由生活条件下的步数和心率的平均值。
Background: The aim of this study was to analyse the validity and accuracy of the low-cost Xiaomi Mi Band 4 (MB4) fitness tracker in relation to step count and heart rate in free-living conditions. Methods: 46 participants join in this study (38.65 ± 14.36 years old). The MB4 was compared with a video recording in laboratory conditions, also with the Sense Wear and Firstbeat monitors in free-living conditions. Results: No significant differences were found in the number of steps in the laboratory protocol between devices, in both, at low and high walking speed. For the free-living conditions, the MB4 showed high values of convergent validity in relation to the Firstbeat monitor during recording in both rest and walking situations. Moreover, the MB4 showed adequate values of convergent validity with the Sense Wear monitor during the 24 h recording, at medium speeds, and climbing stairs. Conclusion: The accuracy and precision of the MB4 is reasonable and can be used to monitor the average of step count and heart rate in free-living conditions.
