This study aimed to investigate the relationship between standardized linear sprint test performance and in-match running metrics in elite soccer players. Forty-seven national-level male youth soccer players (aged 17–23 years) completed a standardized 30-m sprint test with 5- and 10-m split times. Their in-match running performance was then monitored across six games, recording total distance covered, sprinting activity, and peak running speed using wearable tracking devices. The findings indicated moderate to large correlations (r = −0.63 to −0.40) between sprint test performance and match-related peak speeds. Conversely, no substantial correlations were identified between sprint performance and metrics such as sprint count or total distance, likely indicative of the impact of tactics and match context. No significant variations in positional characteristics were identified. The findings provide support for the use of linear sprint testing, particularly over distances of 30 m, as a valid tool for the assessment of sprint capacity in the context of soccer. It is recommended that coaches undertake regular testing of sprint performance in order to monitor speed development and to adapt training programs accordingly.
