“…In addition, it has been suggested that laboratory-based tests are not appropriate protocols for soccer, especially when assessing match stimulation protocols, and therefore their specific relation to soccer match performance may not be accurate. 9,10 Common tests used within youth soccer include the Yo-Yo intermittent test, 11 the 30–15 intermittent fitness test, 12 countermovement jump (CMJ), sprint testing (10m and 30m), repeated sprint ability test (RSA) 13 and agility testing. 14,15 The tests used in practice should be reliable, valid and sensitive to changes in fitness across longitudinal periods.…”

Objectives 1) To evaluate current physical performance tests used within professional male youth soccer; 2) to understand the relationship of these tests performance in relation to specific measures of external and internal training load (TL) to conclude if there is a subsequent change in test performance. Methods Relevant literature was searched using five electronic databases (PubMed Medline, SPORTDiscus, Web of Science, CINAHL and Scopus), with additional articles identified by the authors. Articles relating to TL and physical development assessment within professional male youth soccer players were evaluated. Results Database searches yielded 5683 articles following removal of duplicates. After screening the titles, abstracts and full texts, 28 articles were identified. Both external TL (total distance, high speed distance, duration) and internal TL (rating of perceived exertion, training impulse) measures were found to be associated with improvements in physical test performance across both pre-season and in-season phases. Field-based testing was found to be sensitive to changes in physical performance for aerobic capacity, lower body power/strength and sprint performance. However, limited sensitivity to change was found when assessing player agility performance. Conclusion Future research in this area should look to enhance our understanding of the dose-response of TL with changes in fitness across different age groups in professional male youth soccer.
