    Area of Science:

    • Biomechanics
    • Sports Science
    • Computer Vision

    Background:

    • Running gait analysis is vital for performance and injury prevention.
    • Traditional methods face limitations like unnatural environments, subjective assessments, and high costs.
    • Wearable sensors offer flexibility but can be complex to use.

    Purpose of the Study:

    • To develop a non-wearable, camera-based approach for running gait assessment.
    • To identify initial contact events in a runner's stride using artificial intelligence.
    • To establish a valid, reproducible, and low-cost gait analysis method.

    Main Methods:

    • Utilized a non-wearable camera system to record 40 healthy runners at 240FPS from multiple angles.
    • Investigated various artificial intelligence and object tracking techniques.
    • Validated the system by comparing its initial contact event detection against manually labeled video data.

    Main Results:

    • The proposed computing vision approach accurately identified initial contact events.
    • Achieved a high level of agreement with manual labeling (Intraclass Correlation Coefficient (2,1) = 0.902).

    Conclusions:

    • A non-wearable camera-based system provides a valid and accurate method for running gait analysis.
    • This approach overcomes limitations of traditional and wearable-based methods.
    • Offers a promising low-cost, reproducible solution for assessing running biomechanics.
