摘 要:目的:对Cortex MetaLyzer 3B与Cortex MetaMax 3B测试气体代谢和能量消耗数据进行对比,以期对便携式与固定式气体代谢仪测试效果之间的差别进行评价。方法:15名成年男性在跑台完成2次4.8 km/h、6.4 km/h、8.0 km/h 3个速度的走跑,使用CortexMetaLyzer 3B与Cortex MetaMax 3B分别测定其运动过程中的气体代谢指标并进行统计分析。结果:1)便携式仪器测试组的摄氧量、通气量均高于固定式仪器测试组数据,且走跑时摄氧量增加有非常显著的差异;2)安静状态下心率和能量消耗无差别,走跑时便携式测试组心率和能量消耗均高于固定式测试组;3)两组测试数据存在线性相关;4)使用ICC系数和Bland-Altman法统计分析表明,两组测试数据有非常显著的相关性和一致性。结论:1)便携式气体代谢仪(MetaMax 3B)与固定式气体代谢仪(MetaLyzer 3B)对于运动时摄氧量、CO2呼出量的检测结果有显著差异;2)应用直线回归分析为两仪器测量数据的转换提供简便的公式。但由于样本量较少,该转换关系还需要进一步增加样本量进行验证。Objective:The purpose of this study was to compare Cortex MetaLyzer 3B and Cortex MetaMax 3B test for gas metabolism and energy consumption during running and walking on treadmill in males,and evaluated the difference between portable systems and laboratory-based systems.Methods:15 males complete walking and running on the treadmill twice at 4.8km/h,6.4km/h,8.0km/h speed.The gas metabolism was measured by using the Cortex MetaMax 3B and Cortex MetaLyzer 3B.Results:1) O2,E of portable group measured data was higher than the data of laboratory-based group;2) At the rest,heart rate and energy cost values didn't change in the different sets,but the value in running and walking had difference.The data of portable group was higher than laboratory-based group.3) There is a linear correlation between data using two systems.4) ICC and Bland-Altman analysis between the two groups proved that there was a significant consistency in the data of two sets.Conclusion:1)The test results are significant difference between portable exercise systems(Cortex MetaMax 3B) and laboratory-based exercise systems(MetaLyzer 3B).2) Established a conversion formula for data of two sets by linear regression method,but the formula need to further for validation because of the small sample size.
