Exercise Physiology Research Systems and Software

Wirelessly record a range of physical parameters

Invaluable tools for in-depth study of exercise physiology and biomechanics

RER data for exercise physiology

Wired, Wireless, and Logging Solutions

AcqKnowledge® is an invaluable tool for in-depth study of exercise physiology and biomechanics. Wirelessly record a range of physical parameters (body movement or exercise) with BioNomadix® or the 32-channel Mobita® system. Examine ECG, ventilation, oxygen uptake, carbon dioxide production, blood pressure and core/surface temperature data in real-time, or analyze results in greater detail in an easy-to-read graph format. Each physiological response is recorded in a separate graph channel, with an array of measurements and viewing tools designed to optimize data analysis. Transform data in real time with the online calculation channels, or for advanced post-processing analysis, use AcqKnowledge’s powerful Automated Analysis tools. These pre-loaded, advanced algorithms enable researchers to achieve efficient standardization of results without the need for complicated equations and time consuming manual transformation processes.

Anaerobic Threshold- Use the power of 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.

End Tidal CO2 – Measure end-tidal CO2 on a breath-by-breath basis. Use the AcqKnowledge Find Rate feature to find the peak of the cyclic CO2 concentration signal and export results.

Percent ETCO2

Respiratory Exchange Ratio – AcqKnowledge records RER data and a range of other metabolic signals. An automated script for computing RER is available via download from BIOPAC. (Scripting license is required)

Respiratory Gas Analysis – Use AcqKnowledge with BIOPAC’s specially-designed O2 and CO2 modules for quick, accurate respiratory gas analysis. Achieve optimized response times of 200 ms to record quickly-varying gas concentration levels and track breathing rates of up to 105 BPM.

Camera Systems – Multi Subject Video Monitoring Video, Tutorial, Demo – BIOPAC now offers multi-subject video monitoring systems. The new camera systems record multiple subjects and camera angles, and AcqKnowledge® Media functionality synchronizes the video to the data. High frame rate (100 fps), multi-subject, and standard USB cameras triggered by the AcqKnowledge® Stimulator are also supported.

Gait Analysis – Simultaneously acquire up to 16 channels of gait-specific data, including heel-toe, goniometry, accelerometry and more. One setup might incorporate two channels for heel/toe strike timing, ten channels for EMG signals and four channels of goniometry data. Event markers let users log important events in the data and include comments during or post acquisition.

Range Of Motion – Use AcqKnowledge® to determine the velocity of motion occurring during physical activity. All parts of the body can be evaluated for range of motion for purposes of injury assessment or flexibility quantification. Goniometers are available for evaluating one or two degrees of freedom from the same joint (e.g. wrist flexion/extension and radial/ulnar deviations). Use the X/Y plotting feature to inspect motion resulting from two degrees of freedom. Place torsiometers along the spine to measure twisting along the spinal axis. To determine maximum extension and flexion of the digits, place miniature goniometers on the back of fingers. Determine velocity of motion by using AcqKnowledge to perform a derivative on the recorded movement data, then run a second derivative on the data to calculate acceleration.

Isometric and Isotonic Contraction – Isolate a wide range of muscle groups and evaluate contraction characteristics. For additional insight, acquire EMG data during isotonic force measurement.

GPS Location – Use AcqKnowledge® to import and synchronize a subject’s physical location with experiment data to provide a log of travel which can then be correlated to the recorded physical responses.

Network Data Transfer – AcqKnowledge® with Network Data Transfer has the capability to send all of its data channels over a network to other computers. Other applications can use the AcqKnowledge® data – including physiological recordings, digital markers, and calculation channels – in real time. Network Data Transfer is a separately licensed functionality.

AcqKnowledge® includes a number of automated analysis routines applicable to Exercise Physiology and Biomechanics:

Automated ECG Analysis Package– Collect data from one-, three- or multi lead montages. Analyze heart rate variability with the online R-R calculator and automated HRV analysis. HRV data can be defined on time periods, events, or a user defined selection. Use the powerful ECG averaging function to evaluate changes in the ECG complex before, during and after exercise. Combine ECG data with other parameters to perform a complete physiological examination.

ECG, Analysis, Automation, Exercise

Automated Noninvasive Blood Pressure Analysis– Use the NIBP100D Noninvasive Blood Pressure System to automatically record noninvasive blood pressure. The NIBP100D system attaches to the finger of a human subject to output a continuous blood pressure signal, and is ideal for short and long-term exercise studies. Automatically calculate and display values for systolic, diastolic, mean blood pressure, and heart rate. Export the data directly to a spreadsheet, graph channels, text format or all three.
