国际体力活动问卷与加速度传感器的比较研究——以测量大学生体力活动为例

A Comparative Study of Measuring Physical Activity by International Physical Activity Questionnaire and Acceleration Sensor——A Case Study of College Physical Education

采用国际体力活动问卷(短卷)、加速度传感器GT3X+,在某高校随机选取60名学生进行比较研究。研究发现:采用加速度计和体力活动问卷测量大学生的体力活动有显著的差异性,且有统计学意义。加速度计测量的高强度、中高强度体力活动水平均低于体力活动问卷测量,但静坐时间高于体力活动问卷,且两者的相关性不高。目前国际体力活动问卷被广大科研工作者所采用,但在测量大学生体力活动的同时,要考虑问卷存在的误差性。

By adopting International Physical Activity Questionnaire（ short） andacceleration sensor GT3 X ＋,a comparative study was made among sixty students randomly chosen in a university.The result shows that there are distinct differences between measuring students＇ physical activity by Physical Activity Questionnaire（ short） and acceleration sensor,which is of statistics significance.The levels of high-strength and medium-high strength physical activity measured by acceleration sensor are lower than those measured by the Questionnaire,while time of stillness measured by sensor is higher than that measured by Questionnaire.The correlation of the two results,however,is not high.Currently,International Physical Activity Questionnaire has been widely a dopted in relevant research.But error of questionnaire should be considered when it is used in measuring college students＇ physical activity.
