准确地测量青少年的身体活动水平是青少年身体活动与健康促进研究的关键所在。文章对当前几种主要测量身体活动水平的方法:主观性测量方法(调查法)和直接观察法,热量测定法,双标水法,心率检测器,运动传感器等客观性的测量方法进行了综述。主观性测量方法测得的身体活动量往往高于客观性测量方法所测得的和实际的身体活动量。在选择测量方法时,要根据研究目的和研究对象,选择一种适宜的并能准确、客观地测量青少年身体活动和能量消耗的方法。
Accurately measuring adolescent physical activity levels is the key to adolescent physical activity and health promotion research. In this paper, we review the current methods of measuring the level of physical activity: subjective measurement (survey) and direct observation, calorimetry, double standard water method, heart rate detector, motion sensor objective measurement methods . The amount of physical activity measured by subjective measures tends to be higher than the measured and actual amount of physical activity measured by objective measures. When choosing the measurement method, according to the purpose of the study and the object of study, select a suitable and accurate and objective method of measuring physical activity and energy consumption of adolescents.
