Monitoring Fatigue Status in Elite Team-Sport Athletes: Implications for Practice

Area of Science:

• Sports Science
• Exercise Physiology
• Athlete Monitoring

Background:

• Increasing competition demands in elite team sports necessitate effective monitoring of athlete adaptation and fatigue.
• Understanding athlete status is vital for managing player availability and mitigating injury and illness risks.

Purpose of the Study:

• To evaluate the feasibility and importance of quantifying fatigue status in elite team-sport athletes.
• To identify reliable and sensitive measures for monitoring fatigue beyond traditional maximal performance assessments.

Main Methods:

• Review of traditional and emerging methods for quantifying athlete fatigue.
• Focus on athlete self-report measures, heart-rate-derived indices (autonomic nervous system response), and jump protocols.
• Discussion on the importance of robust rationalization and detection of minimal clinically important differences.

Main Results:

• Traditional maximal physical-performance assessments may be insufficient for detecting fatigue variations during competitive periods.
• Athlete self-report measures, heart-rate indices, and jump protocols are promising nonexhaustive tools for fatigue monitoring.
• The adoption of methods for determining minimal clinically important differences is currently limited among practitioners.

Conclusions:

• Implementing sensitive and reliable fatigue monitoring tools can provide critical information for coaches and athletes.
• Further research is needed to validate the sensitivity of these emerging tools against key indicators like performance, injury, and illness.
