利器还是噱头:可穿戴设备在身体活动测量中的信效度

Sharp Weapon or Trick: Reliability and Validity of Wearable Devices in Physical Activity Measurement

摘要:
目的丰富可穿戴设备的信效度研究证据，减少利用可穿戴设备进行身体活动测评和制订干预措施的阻碍。
方法运用文献资料法、数理统计法对国内外关于可穿戴设备信度与效度的研究进行系统分析。
结果多数可穿戴设备信效度都曾达到要求，但难以找到满足多种情况的可穿戴设备。
结论可穿戴设备缺少针对性；对活动类型进行辨识将是可穿戴设备的发展方向之一；个体应根据需要选择合适的可穿戴设备。

Abstract:
Objective To enrich the research on the reliability and validity of wearable devices and reduce the obstacles of intervention measures on the physical activity assessment and formulations with wearable devices.
Methods Literature review and statistics are used to analyze the reliability and validity of wearable devices at home and abroad.
Results The study found that the reliability and the validity of most wearable devices can meet the requirements under certain conditions, but it is difficult to find an equipment that meets all conditions.
Conclusions As there is shortage of targeted devices so far, the identification of the types of physical activities will be a tendency for wearable devices.The devices should be selected according to human needs and conditions.
