TL;DR
This study explores using monocular broadcast videos to assess athlete fatigue in football by extracting kinematic signals and analyzing acceleration-speed profiles, offering a low-cost alternative to traditional methods.
Contribution
It introduces a novel pipeline combining state-of-the-art game state reconstruction with a new kinematics algorithm to derive fatigue-related metrics from broadcast footage.
Findings
Monocular GSR can recover kinematic patterns suitable for fatigue analysis.
The approach is sensitive to trajectory noise and calibration errors.
It demonstrates potential as a low-cost fatigue assessment method.
Abstract
Fatigue monitoring is central in association football due to its links with injury risk and tactical performance. However, objective fatigue-related indicators are commonly derived from subjective self-reported metrics, biomarkers derived from laboratory tests, or, more recently, intrusive sensors such as heart monitors or GPS tracking data. This paper studies whether monocular broadcast videos can provide spatio-temporal signals of sufficient quality to support fatigue-oriented analysis. Building on state-of-the-art Game State Reconstruction methods, we extract player trajectories in pitch coordinates and propose a novel kinematics processing algorithm to obtain temporally consistent speed and acceleration estimates from reconstructed tracks. We then construct acceleration--speed (A-S) profiles from these signals and analyze their behavior as fatigue-related performance indicators. We…
