The relationship between ventilation and oxygen uptake becomes non-linear above the anaerobic threshold. This threshold can be determined by establishing a ratio of inspired volume and VO2 consumption. Anaerobic threshold also known as lactate threshold (LT) or lactate inflection point (LIP) is the point when lactic acid starts to amass in the blood stream.
Use AcqKnowledge® to establish a ratio of inspired volume and VO2 consumption and to integrate the air flow signal to obtain total inspired volume in real time.
Divide the identically integrated O2 consumption flow signal by the inspired volume; the resultant value will be constant to the point of anaerobic threshold. After the threshold is reached, this value starts to drop.

There is overwhelming evidence that combining multiple physiological measures provides greater power to discriminate mental workload as well as other cognitive states. Researchers frequently acquire disparate data streams for studies in cognition, human factors, ergonomics, user experience, and more.
