This study attempted to show that the use of a computer-based system is as accurate and reliable as the Douglas bag method for the analysis of respiratory exchange measurements during exercise. Fourteen submaximal exercise tests were performed on a bicycle ergometer where simultaneous metabolic determinations were made by the two different respiratory analysis methods. The metabolic data observed included VO2, VE, CO2%, and 02%. An error in calibration of the CO2 gas analyzer was found which produced a significant difference (0.05 level) in the CO2% measurement between the means of the two methods of gas analysis. This may have contributed to the significant difference found between the means in the measurement of VE analyzed by the two methods presented. It is indicated from this study that the computer-based system provides the researcher with data that is accurate, reliable, and reproducable.
