Summary
This study introduces a novel self-biofeedback heart rate (HR) controller for improving exercise adaptation. The system effectively regulates heart rate during exercise by adjusting running speed, stride length, and pitch of gait.
Area of Science:
- Exercise Physiology
- Biomedical Engineering
- Human Movement Science
Background:
- Cardiac adjustment to exercise is crucial for performance and safety.
- Existing methods for controlling heart rate during exercise have limitations.
- Biofeedback offers a potential avenue for personalized exercise control.
Purpose of the Study:
- To develop and evaluate a novel self-biofeedback heart rate (HR) controller.
- To analyze the relationship between preset HR levels and physiological/kinematic responses during exercise.
- To determine the efficacy of the system in regulating HR during physical activity.
Main Methods:
- Development of a self-biofeedback HR controller.
- Experimental analysis of HR, running speed (RS), stride length (ST), and pitch of gait (PI) in 7 subjects.
- Testing various preset HR levels (80-160 bpm) during exercise.
Main Results:
- The controller achieved HR regulation within +/- 4% of preset levels.
- Running speed, stride length, and pitch of gait adjusted rapidly to exercise demands.
- A proportional relationship was observed between preset HR and increases in RS, ST, and PI.
- At higher HRs (160-170 bpm), HR and PI exhibited synchronized rhythms.
Conclusions:
- The developed self-biofeedback HR control system enables precise HR regulation during exercise.
- Exercise parameters like running speed, stride length, and pitch of gait are key modulators of HR.
- This technology has potential applications in optimizing exercise training and rehabilitation.
