Assessment and reporting methods of post-match fatigue and readiness to train in elite adult soccer players: A survey study

This study examined post-match fatigue assessment practices used by practitioners working in elite male soccer and explored how these data were analysed and applied to inform training and readiness related decisions. Seventy-one practitioners from professional leagues across 13 countries completed a 44-question online survey covering background information, test selection, timing of testing, data analysis, and application of findings. Time constraints and staff availability were the primary factors influencing test selection and frequency. Jump testing was widely implemented, with 98% ( n  = 61) of respondents reporting use of the countermovement jump (CMJ). Common isometric assessments included short-lever hip adduction using force frame technology and prone hamstring testing at 30° knee flexion. Isometric contraction durations ranged from 3–7 s, with 47% ( n  = 20) using a 3-s maximum voluntary contraction (MVC) and 40% ( n  = 19) using a 5-s MVC. Peak force was the most analysed metric. Biochemical monitoring was uncommon, with 84% ( n  = 46) of respondents reporting no use of biochemical markers. Among those who did, creatine kinase (CK) was the most frequently measured variable. Subjective monitoring was widely adopted, with the Hooper Index the most common tool ( n  = 39 88%). Muscle soreness ( n  = 50 98%), fatigue ( n  = 49 96%), and sleep quality ( n  = 48 94%) were the most frequently assessed measures, while mood ( n  = 36 70%) and stress ( n  = 31 60%) were monitored less often. Match day plus two (MD + 2) was the most common comprehensive testing day, typically including players who completed 15–60 min of match play. Microsoft Excel was the primary analysis tool with n  = 35 (85%) using the software, with many practitioners relying on percentage change thresholds rather than reliability metrics, confidence limits, or smallest worthwhile change calculations.
