    Summary

    This study presents a novel method for measuring rodent physiological parameters during spontaneous exercise, reducing animal stress. This technique allows for extended monitoring of parameters like pain threshold without environmental disturbances.

    Area of Science:

    • Physiology
    • Animal Behavior
    • Exercise Science

    Background:

    • Current rodent exercise studies often rely on forced exercise, introducing stress.
    • Measuring physiological parameters in rodents typically requires invasive or stressful methods.

    Purpose of the Study:

    • To describe a convenient method for measuring physiological parameters during spontaneous rodent exercise.
    • To reduce stress associated with physiological measurements in rodent research.

    Main Methods:

    • Utilized spontaneous running patterns in exercise wheels for hamsters and rats.
    • Employed a microprocessor system to quantify running activity.
    • Enabled measurement of physiological parameters like pain threshold, blood pressure, and heart rate.

    Main Results:

    • Demonstrated that hamsters reach maximal running activity almost immediately.
    • Showed that rats gradually increase running activity over approximately 4 weeks, averaging 7 km/day.
    • Successfully measured physiological parameters during spontaneous activity without altering the animals' environment.

    Conclusions:

    • The described method offers a less stressful alternative for physiological monitoring in rodents during exercise.
    • This technique facilitates extended, non-invasive measurement of key physiological parameters in freely moving rodents.
    • The findings support the use of spontaneous exercise models for more naturalistic physiological research in rodents.
