​

  • Audible and visual cadence target​ to aid in subject compliance

​

  • Measured variables include:

    • Force

    • *Cadence

    • *Rate of Work

    • *Technique Assessment Factor (TAF)

    • Total Work Accumulated

    • Elapsed Time

            *Instantaneous or Cycle Averaged

The Knee Extension Ergometer is used extensively to investigate muscle physiology research questions, specifically the peripheral limitations to maximal oxygen consumption such as impaired endothelial-dependent vasodilation, fiber atrophy, capillary rarefaction, compromised metabolism, and more. The Technavance Solution incorporates a NIST-traceable calibrated load cell, optical encoder, magnetic switch and photomicrosensors to provide highly accurate measurements of a wide range of parameters in such investigations. The system’s user-friendly customizable control software reports both instantaneous and average measurements of rate of work, force, cadence and efficiency, as well as elapsed time and completed revolutions. The user interface also provides both visual and audio feedback to ensure optimal subject compliance. Results can be exported from the software or fed directly into third-party data acquisition systems.
