    Area of Science:

    • Biomedical Engineering
    • Sports Science
    • Wearable Technology

    Background:

    • Traditional electrocardiogram (ECG) monitoring is challenging for athletes during physical activity.
    • Aquatic environments pose unique challenges for electronic monitoring systems due to water ingress and signal interference.

    Purpose of the Study:

    • To develop and describe a low-frequency telemetry system for high-quality ECG measurements in active swimmers.
    • To ensure the system allows for normal swimming and diving movements.

    Main Methods:

    • A waterproof low-frequency telemetry transmitter with a small loop antenna worn by the swimmer.
    • A receiver system utilizing a single wire loop antenna around the swimming pool.
    • Waterproof ECG electrodes and transmitter casing.

    Main Results:

    • The system enables high-quality ECG measurements on active swimmers.
    • The waterproof design and antenna configuration allow complete freedom of action for diving and swimming.
    • The transmitter utilizes miniature components and thick film techniques for reliability and reduced volume.

    Conclusions:

    • The developed telemetry system effectively overcomes the challenges of ECG monitoring in active swimmers.
    • This technology facilitates unobtrusive, high-fidelity physiological data collection during aquatic sports.
    • Miniaturization and waterproof construction are key to the system's success.
