Anaerobic Threshold (AT)

VO2 Data AcqKnowledge

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.

Multimodal Workload Measurements | Combining fNIRS, ECG/HRV, Eye Tracking & Stimulus Presentation

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.

Watch the online presentation to learn how to:
• Operate a multimodal experiment using: fNIRs, ECG/HRV, eye tracking, and stimulus presentation
• Record high quality data
• Optimize the setup
• Synchronize devices
• Analyze data
