本研究评估了便携式代谢测量系统Aerosport TEEM 100的实用性。通过将Aerosport TEEM 100中等流量呼吸速度计和吸嘴与经确认的系统Rayfield系统串联，在12名受试者（年龄= 25 +/- 4岁）中收集了共计505个数据点[242个来自增量（INC）运动，263个来自恒定负荷（CL）运动]。当VO 2值被分为不同类别时，（< 1.5，1.5-2.0，2.0-2.5，2.5-3.0，> 3.0 l.min-1），两种代谢测量系统之间的VO 2，VCO 2，VE，RER，%ECO2，和%EO2，测量误差在2%~ 11%之间。INC和CL运动期间两个系统之间的VO 2值的相关性分别为r = 0.95（SEest +/- 0.18 l.min-1）和r = 0.96（SEest +/- 0.29 l.min-1）。对于INC和CL，RER的相关性分别为r = 0.82（SEest +/- 0.08）和r = 0.47（SEest +/- 0.11）。从目前的调查结果表明，Aerosport TEEM 100具有实用价值的VO 2的评估，但估计碳水化合物和脂肪利用RER应谨慎使用。
The present study evaluated the utility of a portable metabolic measurement system, the Aerosport TEEM 100. A total of 505 data points [242 from incremental (INC) and 263 from constant load (CL) exercise] were collected on 12 subjects (age = 25 +/- 4 yr), by placing the Aerosport TEEM 100 medium flow pneumotach and mouthpiece in-line with a validated system, the Rayfield system. When VO2 values were separated into categories (< 1.5, 1.5-2.0, 2.0-2.5, 2.5-3.0, > 3.0 l.min-1), there was a small but statistically significant difference between the two metabolic measurement systems for VO2, VCO2, VE, RER, %ECO2, and %EO2 during both INC and CL exercise and measurement error for VO2 ranged between 2% and 11%. Correlations for VO2 values during INC and CL exercise between the two systems were r = 0.95 (SEest +/- 0.18 l.min-1) and r = 0.96 (SEest +/- 0.29 l.min-1), respectively. Correlations for RER were r = 0.82 (SEest +/- 0.08) and r = 0.47 (SEest +/- 0.11), for INC and CL, respectively. Results from the present investigation indicate that the Aerosport TEEM 100 has utility for the assessment of VO2, but the estimation of carbohydrate and fat utilization from RER should be used with caution.
