本研究的目的是测试Aerosport KB 1-C便携式代谢测量系统对标准道格拉斯袋法的有效性。在踏车测力期间，在静止和功率输出为50、100、150、200和250 W时，同时测量每分钟通气量（（V）/点（E））、耗氧量（（V）/点（2））和二氧化碳产生量（（V）/点CO2）。在100、150和250 W时，KB 1-C和道格拉斯袋之间的（V）超过点（E）、（V）超过点O（2）和（V）超过点CO2均无显著性差异（P > 0.05），而KB 1-C组之间有显著性差异（P
The purpose of this study was to test the validity of the Aerosport KB1-C portable metabolic measurement system against the criterion Douglas bag method. During cycle ergometry, simultaneous measurements of minute ventilation ((V) over dot (E)), oxygen consumption ((V) over dot (2)), and carbon dioxide production ((V) over dot CO2) were made at rest and at power outputs of 50, 100, 150, 200, and 250 W. No significant differences (P > 0.05) were observed for (V)over dot (E), (V) over dot O (2), and (V) over dot CO2 between the KB1-C and Douglas bag at 100, 150, and 250 W, while the KB1-C was significantly different (P
