Mental fatigue in football: methodology and experimental protocol

Area of Science:

• Sports Science
• Neuroscience
• Cognitive Psychology

Background:

• Prolonged cognitive tasks induce mental fatigue, impairing cognitive functions vital for sports.
• Football performance relies heavily on attention, decision-making, and motor coordination, all susceptible to mental fatigue.

Purpose of the Study:

• To investigate the effects of mental fatigue on neurophysiological, visual, technical, and motor performance in football players.
• To establish a protocol for monitoring mental fatigue in high-performance athletes.
• To inform individualized intervention strategies for managing mental fatigue in sports.

Main Methods:

• Randomised controlled trial with pre-test/post-test design.
• Inclusion of 34 football players (17 male, 17 female) aged ≥18 years with ≥1-year experience.
• Cognitive fatigue induced via Stroop Task; control group received low cognitive load.
• Data collection: EEG (theta/alpha bands), eye tracking, sport-specific tests (Loughborough Soccer Passing Test, Y-Shaped Agility Reaction Test), subjective fatigue scales (Fatigue Assessment Scale, Visual Analogue Scale).
• Statistical analysis: intra- and inter-group comparisons, correlation, and regression models.

Main Results:

• No data available as this is a protocol paper.
• Anticipated findings based on literature: mental fatigue associated with altered EEG activity (theta and alpha bands).
• Expected changes in gaze behavior (less efficient) and decrements in football-specific skills compared to the control group.

Conclusions:

• The study protocol integrates subjective, physiological, and performance measures for a comprehensive understanding of mental fatigue in football.
• Findings are expected to enhance knowledge of mental fatigue's impact on athletic performance.
• Results will guide the development of monitoring and intervention strategies for elite football players.
