Development of new predictive model for physical activity of children adjusting for body composition and typical motion

本研究的目的是基于成人和儿童在合成加速与代谢当量(METS)关系上的差异，提出新的儿童体力活动预测模型。用成人预测方程估算儿童体力活动时，与双标记水法实测值相比，存在高估现象。这意味着我们必须使用针对儿童的特定预测模型来更准确地估计儿童的Met。

The aim of study is to propose the new predictive model for physical activity of children based on the difference between adults and children on relationship of synthetic acceleration to metabolic equivalents(METs). When we used the adult predictive equation to estimate the physical activity of children, it led to overestimation comparing to measured values using by doubly labeled water method. It means that we must use the specific predictive model for children to estimate children's METs more correctly.
