The Perception & Action Podcast 523 – Critical Fluctuations as an Early Warning Signal of Sports Injuries: Proof of Concept
6 snips
Jan 14, 2025 Can fluctuations in performance data reveal the risk of sports injuries? This discussion delves into a novel approach to predicting injuries in youth soccer players. By examining psychological and physiological indicators, the researchers suggest that certain transition points can serve as early warning signs. The conversation emphasizes the importance of further research to enhance this predictive model and ensure athlete safety.

Episode notes
Injury Prediction through Instability
- Injuries may occur as a result of phase transitions, abrupt shifts between attractor states in movement.
- Instability around the current attractor state precedes these transitions, suggesting potential for injury prediction.
Dynamic Complexity as an Early Warning Signal
- The study uses "dynamic complexity" to measure fluctuations and deviations in time series data of athletes.
- This helps detect critical fluctuations as potential early warning signals of injury.
Exemplar Cases Supporting the Hypothesis
- The study analyzed data from 23 youth soccer players who experienced at least one injury.
- Two exemplar cases showed critical fluctuations preceding injury, supporting the hypothesis.
