Development and Assessment of an On-Line Aerobic Measurement System
Abstract
An on-line aerobic measurement system was developed to meet the needs of an exercise physiology laboratory. It utilized a HP 9820 desk top calculator to compute parameters from signals averaged over a 13 second sample period. An infrared CO2 and fuel cell O2 analyzer were employed for gas concentrations and a Fleisch pneumotachograph for air flow. A variable volume mixing chamber was utilized to avoid breath-by-breath variations in gas concentrations. Reliability and validity studies between this on-line system and the traditional Douglas bag collection method showed no significant differences in VO2, VE or FEO2 for submaximal work loads or for the determination of VO2 max with treadmill running.
