“Do players really slow down in the second half — or are we measuring the wrong thing?” ⚽️🔍 Coaches often blame late-game dips on fatigue. Analysts point to falling totals. But two peer-reviewed investigations, combined into one applied study by the 👉 Football Intelligence & Performance Department at LALIGA, tell a sharper story: 📊 The scoreboard redistributes work by position. ⏱️ The way we time the game (total vs. ball-in-play) can create illusions. What we tested 🔹 Belief 1: Second-half performance always drops. 🔹 Belief 2: Running output is stable regardless of the scoreline. Key insights 1️⃣ Match status redistributes work • Losing: defenders increase medium/high-intensity running and sprints. • Winning: attackers (especially wide roles) run more at high speed. • Central midfielders remain stable. 2️⃣ Second-half “drop” depends on the denominator • Using ball-in-play time, high-speed running and sprints per minute are largely stable. • The late-game decline appears when dividing by total time, inflated by stoppages. • Exception: centre forwards show a real second-half reduction — manage carefully. 3️⃣ Context sharpens interpretation • Effective time decreases late in games, inflating false “drops.” • Home matches often carry higher high-speed demands, while stronger opponents raise intensity. Practical applications 🔧 Reporting: Pair totals with ball-in-play metrics. Always tag by scoreline and venue. 🏋️ Training: • Forwards → repeated sprints after min 60. • Defenders when losing → high-line chase mode, recovery runs. • Wide players → cruise-then-burst patterns. • Central roles → compact-to-press transitions. 🧠 Substitutions: Build status-aware thresholds, especially for strikers. Why it matters The denominator you choose changes decisions on substitutions, training, and feedback. Treat the pitch as a living lab: test beliefs, then act with clarity. 🔬⚽️ Research origin • Do elite soccer players cover longer distance when losing? Differences between attackers and defenders. DOI: https://lnkd.in/d3wjzWRh • Elite soccer players do not cover less distance in the second half of the matches when game interruptions are considered. DOI: https://lnkd.in/dAMYWy3t 👉 Final question: If we all start reporting second-half performance using ball-in-play minutes and tagging match status… which “truth” at your club would change first — conditioning plans, substitution timing, or tactical evaluation? 🤔 🎧 Podcast: https://lnkd.in/d3H7Hjdb 🔗 Web: https://lnkd.in/d-JAs7hB #FootballScience #PerformanceAnalysis #EffectivePlayingTime #MatchStatus #HighSpeedRunning #SprintPerformance #SportsAnalytics #FootballCoaching #EvidenceBasedCoaching #LALIGA #FootballIntelligence
