| 中文摘要: |
| 现代社会生活方式的改变，给人类健康带来极大的威胁。通过增加日常体力活动量（约占总能量消耗量的20%），可以有效减少和控制慢性非传染性疾病的发生和发展，减轻社会医疗负担。便携式遥测气体代谢仪可测量自由状态下的体力活动量，因而被广泛应用于智能手机、可穿戴和虚拟现实设备的开发和应用，以及竞技体育科研等健康促进领域的研究，目前对便携式遥测气体代谢仪准确的使用范围知之不深。本文对常见的几种便携式遥测气体代谢仪（包括：Cosmed K4b2、Metamax 3B/VmaxST、Oxycon Mobile、VO2000）在不同环境、不同条件下测量的信度和效度及其核心指标VO2、VCO2和VE进行分析，以期为相关的研究和应用提供参考。 |
| 英文摘要: |
| The changes of lifestyle in modern society bring great threat to human health. Enhancing the level of physical activity(PA), which usually accounts for 20% of the total energy expenditure, can effectively decrease and control the occurrence of chronic non-infectious diseases and reduce the burden of social medical service. Portable telemetric gas metabolic systems can assess PA in free state. It has been applied to health promotion researches, the development and application of smart phones, wearable devices and visual reality equipment as well as competitive sports researches. However, people do not understand much about the correct use of the systems. The paper focuses on the reliability and validity of several portable telemetric gas metabolic systems, including Cosmed K4b2, Metamax 3B/VmaxST, Oxycon Mobile and VO2000, at different environments and conditions, especially the core indexes of VO2, VCO2 and VE, so as to provide reference for the relative research and application. |
