数体融合:可穿戴设备在体育活动测量中的应用与展望

Integration of Digitization and Sports:Application and Prospect of Wearable Devices in Sports Activity Measurement

通过文献资料法和逻辑分析法,对可穿戴设备在身体活动测量中的信效度进行分析,探讨身体活动类型、佩戴位置、测量指标、工具类型和测量环境等因素对测量结果的影响,并进一步从适用对象、设备类型、佩戴位置、身体活动指标、执行标准、研究环境和技术意用性等维度探讨可穿戴设备的发展方向。由可穿戴设备所反馈的各项身体活动数据得出:可穿戴设备对儿童青少年及老年人身体活动干预较为有效;可穿戴设备对复杂的活动测量精度较差;可穿戴设备须选择步进计数、能耗和心率等基础类指标作为测评衡量参数;可穿戴设备在身体活动、养成健康行为层面对儿童青少年和老年人的促进作用效果有限。

Through the methods of literature review and logical analysis,this paper analyzes the reliability and validity of wearable devices in sports activity measurement,discusses the influence of sports activity type,wearing position,measurement index,tool type and measurement environment on the measurement results,and further discusses the development direction of wearable devices from the dimensions of applicable object,device type,wearing position,physical activity index,implementation standard,research environment and technical applicability.According to the physical activity data fed back by wearable devices,wearable devices are more effective in physical activity intervention for children,adolescents and the elderly;wearable devices have poor measurement accuracy for complex activities;wearable devices must choose basic indicators such as step count,energy consumption and heart rate as evaluation parameters;wearable devices have limited effects on promoting physical activity and healthy behavior in children,adolescents and the elderly.
