Acute and Residual Soccer Match-Related Fatigue: A Systematic Review and Meta-analysis

Area of Science:

• Sports Science
• Exercise Physiology
• Biochemistry

Background:

• Understanding soccer players' fatigue and recovery is crucial for optimizing performance and reducing injuries.
• Assessing recovery responses between actual match-play and simulation protocols is vital for effective training program design.

Purpose of the Study:

• To detail fatigue development and recovery in soccer players during actual matches.
• To compare recovery responses between 11 vs. 11 match-play and simulated match protocols.

Main Methods:

• Systematic literature search of PubMed and SportDiscus databases.
• Inclusion of longitudinal studies with soccer players, matches or validated protocols (>45 min).
• Analysis of 77 eligible studies (n=1105) calculating 1196 effect sizes.

Main Results:

• Significant alterations in immunological, hormonal, and neuromuscular markers were observed at halftime and post-match.
• Impairments in muscle function, physical performance, and well-being persisted up to 72 hours post-match.
• Actual 11 vs. 11 matches induced greater muscle damage, inflammatory, and perceptual responses compared to simulation protocols.

Conclusions:

• A 72-hour recovery period is insufficient for complete restoration of physiological balance post-soccer match.
• Recovery needs vary, necessitating individualized approaches rather than a 'one size fits all' strategy.
• Coaches should tailor training sessions within 72 hours post-match to manage load effectively, considering the greater impact of real matches on player recovery.
