加速度计在儿童体力活动测量中的应用

加速度计是一种客观测量体力活动的工具,因其小巧轻便且不受受试者回忆准确性和认知水平的限制,近年来在儿童体力活动测量中得到广泛应用。然而到目前为止,较少有研究关注加速度计使用方法的标准化,如加速度计的选择、采样间隔、佩戴部位、佩戴时间的确定、数据处理等。针对儿童体力活动的特点,就上述问题做一综述,以期提供一些在加速度计使用中的实用性参考。

Physical Activity Assessment Using Accelerometers among Children

As an objective measure of physical activity,accelerometer is unobtrusive and doesn't rely on participants' recall and cognitive ability.Therefore,it has been widely used for assessing physical activity among children in recent years.However,few studies,if any,have focused on standardized application of this instrument,for instance,choice of accelerometers,epoch length,wearing position,wearing days and data processing.The purpose of this narrative review is to summarize previous findings on these aspects wi...
