05 Jul The Impact of Technical Fatigue on Football Performance: An Analysis of LALIGA EA Sports 2023/24 Season
Abstract
This study examines the phenomenon of technical fatigue in football, focusing on its impact on player performance during matches. By analyzing key performance metrics from the LALIGA EA Sports 2023/24 season, we identify significant declines in success rates for «first actions» and «passes» in the second half of matches. These findings suggest that technical fatigue is a critical factor influencing match outcomes.
Introduction
Football is a physically and mentally demanding sport, requiring players to maintain high levels of performance throughout the match. Fatigue, both physical and cognitive, can significantly impact a player’s ability to perform. This study aims to explore the concept of technical fatigue, defined as the decline in a player’s ability to execute specific skills with precision and effectiveness over time. We focus on two high-volume actions: «first actions» and «passes,» to determine how technical fatigue manifests and correlates with match results.
Methods
We collected and analyzed performance data from the LALIGA EA Sports 2023/24 season. The dataset included metrics for «first actions» and «passes,» recorded for both the first and second halves of each match. The primary variables of interest were the success rates of these actions. We calculated the differences in these success rates between the two halves to quantify technical fatigue. Additionally, match outcomes were categorized as win, draw, or loss for each team, and mapped to numerical values (1 for win, 0 for draw, -1 for loss) for correlation analysis.
Results
The analysis revealed a notable decline in the success rates of both «first actions» and «passes» in the second half of matches, suggesting the presence of technical fatigue. Specifically:
- First actions: On average, teams experienced a 1.3% reduction in effectiveness.
- Passes: The success rate for passes decreased by 1.7%.
Furthermore, we found a negative correlation between the decline in pass success rates and match outcomes, indicating that greater technical fatigue in passing is associated with less favorable results.
Discussion
These findings highlight the significance of technical fatigue in football performance. The reduction in success rates for «first actions» and «passes» underscores the challenges players face in maintaining precision and effectiveness as fatigue sets in. This study suggests that technical fatigue is not only a physical phenomenon but also closely linked to cognitive factors, such as decision-making and concentration.
The importance of the «second unit» or substitutes is emphasized, as they play a crucial role in mitigating the effects of fatigue. Additionally, strategic considerations, such as «resting with the ball» and proactive game management, can help teams better handle technical fatigue.
Conclusion
Technical fatigue is a critical factor affecting football performance, particularly in the second half of matches. This study demonstrates that the success rates of high-volume actions like «first actions» and «passes» decline as matches progress, correlating with less favorable outcomes. Addressing both physical and cognitive aspects of fatigue through comprehensive training and strategic in-game management is essential for maintaining optimal performance.
Future research should focus on identifying specific players most susceptible to fatigue and developing targeted interventions to enhance their resilience. Understanding and managing technical fatigue can provide a competitive edge in professional football.
