Abstract

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.

摘要

本研究评估了便携式代谢测量系统Aerosport TEEM 100的效用。通过将Aerosport TEEM 100中流量呼吸流速计和咬嘴与经过验证的系统Rayfield系统串联，对12名受试者（年龄 = 25±4岁）收集了总共505个数据点[242个来自递增（INC）运动，263个来自恒定负荷（CL）运动]。当将VO2值分为不同类别（<1.5、1.5 - 2.0、2.0 - 2.5、2.5 - 3.0、>3.0 l·min-1）时，在INC和CL运动期间，两种代谢测量系统在VO2、VCO2、VE、RER、%ECO2和%EO2方面存在微小但具有统计学意义的差异，VO2的测量误差在2%至11%之间。两种系统在INC和CL运动期间VO2值的相关性分别为r = 0.95（估计标准误±0.18 l·min-1）和r = 0.96（估计标准误±0.29 l·min-1）。RER在INC和CL运动期间的相关性分别为r = 0.82（估计标准误±0.08）和r = 0.47（估计标准误±0.11）。本研究结果表明，Aerosport TEEM 100可用于评估VO2，但从RER估计碳水化合物和脂肪利用率时应谨慎使用。
