Metabolic Function

iWorx Metabolic Measurement Solutions are compact, cost effective and easy-to-use systems capable of accurately and reliably measuring and analyzing oxygen consumption and carbon dioxide production in resting and exercising subjects in support of:

• – Human exercise physiology research
• – Small animal metabolic research
• – Fitness assessment

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
