LabScribe Metabolic Calculations

LabScribe automates and streamlines both the analysis and reporting of metabolic parameters from a test subject. The calculations are derived from the input data acquired during a test which would typically include oxygen and carbon dioxide concentrations, lung volumes, and heart rates. Raw data can be viewed in real-time within the LabScribe Main window.

Setup and Calibrate:

Streamlined setup and calibration reduces error and saves time.

Measure:

  • Relative and absolute oxygen consumption (VO2)
  • Relative and absolute carbon dioxide production (VCO2)
  • Respiratory Exchange Ratio (RER)
  • Ventilatory Equivalent (VE/VO2)
  • Expired Minute Ventilation (VE)
  • Metabolic Equivalent (METS) and more

Plot:

The Metabolic Calculations Module also allows these parameters to be plotted against time or each other to yield valuable information about the aerobic fitness of the subject.These plots include:
  • VO2, VCO2, RER vs. Time
  • VCO2 vs. VO2
  • VE vs. VO2
  • VE vs. VCO2
  • HR, VCO2 vs. VO2
  • %Fat
  • VE vs. Watts
  • HR, VO2/HR vs. Watts
  • VO2, VCO2 vs. Watts
  • VE/VO2, VE/VCO2 Vs. Watts
  • Resting Energy Expenditure (REE)
The Metabolic Calculations Module was enhanced considerably with the release of LabScribe V3 to serve our customers performing fitness assessment tests. Here are some noteworthy changes:
  • It is now possible to setup and save a subject profile while performing a fitness assessment test. During subsequent tests, the same subject profile can be loaded and data can be easily compared. This feature provides a convenient and simple way to track progress over time.
  • An intuitive user interface has been created to setup and customize training zones for subjects based on % of maximum heart rate or within a specific heart rate range.

Control Exercise Equipment

  • Treadmills: Treadmill that support the Trackmaster Protocol, such as treadmills from Trackmaster, Woodway can be controlled by Labscribe
  • Ergometers : Ergometers supporting the ANT+ FEC Trainer protocol can be controlled by LabScribe
  • Lode Ergometer: Lode Ergometers can be controlled by LabScribe.

Record ANT+ Sensor Data

Record data from various ANT+ sensors such as.
  • Heart Rate Sensors
  • Bike Power Sensors
  • Muscle Oxygen Sensors
Detailed information about using the modules is in the LabScribe Manual
