This study introduces a computer-controlled treadmill system for precise heart rate management during exercise. Fuzzy Proportional-Integral control demonstrated superior performance in maintaining target heart rates compared to traditional methods.

Area of Science:

  • Exercise Physiology
  • Biomedical Engineering
  • Control Systems

Background:

  • Accurate heart rate monitoring is crucial for effective exercise prescription and physiological assessment.
  • Traditional treadmill exercise control often struggles with maintaining precise heart rate targets due to physiological variations.

Purpose of the Study:

  • To develop a computer-controlled treadmill system for precise heart rate regulation during exercise.
  • To compare the effectiveness of fuzzy Proportional-Integral (PI) control with conventional Proportional-Integral-Derivative (PID) control for heart rate tracking.

Main Methods:

  • A novel computer-controlled treadmill system with integrated data acquisition and processing was designed.
  • A robust heart rate measurement algorithm was developed for real-time variation analysis.

Related Experiment Videos

  • Both PID and fuzzy PI control algorithms were implemented and evaluated for treadmill speed and gradient adjustment.

    • Main Results:

    • The developed system effectively minimized heart rate deviations from a preset profile by adjusting treadmill speed and/or gradient.
    • The fuzzy PI control algorithm exhibited superior heart rate tracking performance compared to the conventional PID controller.
    • A functional heart rate-based exercise protocol was successfully implemented on the system.

    Conclusions:

    • Computer-controlled treadmills offer enhanced precision for heart rate management in exercise settings.
    • Fuzzy PI control presents a more effective approach for dynamic heart rate regulation during treadmill exercise.
    • The developed system and algorithm provide a robust platform for advanced, personalized exercise protocols.
