However, there has been little consideration of the relationship between lower-limb screening and the loading response to soccer activities. Objective<\/jats:bold>:<\/jats:italic> To quantify the efficacy of using screening tests to predict the loading elicited in soccer-specific activities and to develop a hierarchical ordering of musculoskeletal screening tests to identify test redundancy and inform practice. Design<\/jats:bold>:<\/jats:italic> Correlational. Setting<\/jats:bold>:<\/jats:italic> Professional soccer club academy. Participants<\/jats:bold>:<\/jats:italic> A total of 21 elite male soccer players aged 15.7 (0.9) years. Intervention<\/jats:bold>:<\/jats:italic> Players completed a battery of 5 screening tests (knee to wall, hip internal rotation, adductor squeeze, single-leg hop, and anterior reach) and a 25-minute standardized soccer session with a Global Positioning System unit placed at C7 to collect multiplanar PlayerLoad data. Main Outcome Measures<\/jats:bold>:<\/jats:italic> Baseline data on each screening test, along with uniaxial PlayerLoad in the mediolateral, anteroposterior, and vertical planes. Results<\/jats:bold>:<\/jats:italic> Stepwise hierarchical modeling of the screening tests revealed that dominant leg knee-to-wall distance was the most prevalent and powerful predictor of multiplanar PlayerLoad, accounting for up to 42% of variation in uniaxial loading. The adductor squeeze test was the least powerful predictor of PlayerLoad. Of note, one player who incurred a knee injury within 3 weeks of testing had shown a 20% reduction in knee-to-wall distance compared with peers, and elicited 23% greater PlayerLoad, supporting the hierarchical model. Conclusions<\/jats:bold>:<\/jats:italic> There was some evidence of redundancy in the screening battery, with implications for clinical choice. Hierarchical ordering and a concurrent case study highlight dominant leg knee-to-wall distance as the primary predictor of multiaxial loading in soccer. This has implications for the design and interpretation of screening data in elite youth soccer.<\/jats:p>","DOI":"10.1123\/jsr.2018-0175","type":"journal-article","created":{"date-parts":[[2018,10,9]],"date-time":"2018-10-09T17:29:59Z","timestamp":1539106199000},"page":"860-865","source":"Crossref","is-referenced-by-count":3,"title":["The Efficacy of Lower-Limb Screening Tests in Predicting PlayerLoad Within a Professional Soccer Academy"],"prefix":"10.1123","volume":"28","author":[{"given":"Charlie","family":"Bowen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristian","family":"Weaver","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicola","family":"Relph","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matt","family":"Greig","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"key":"ref131","doi-asserted-by":"crossref","first-page":"587","DOI":"10.1123\/ijspp.2015-0331","article-title":"Training load and player monitoring in high-level football: current practice and perceptions","volume":"11","author":"Akenhead","year":"2016","journal-title":"Int J Sports Physiol Perform"},{"key":"ref231","doi-asserted-by":"crossref","first-page":"3550","DOI":"10.1007\/s00167-014-3222-z","article-title":"The association of dorsiflexion flexibility on knee kinematics and kinetics during a drop vertical jump in healthy female athletes","volume":"23","author":"Malloy","year":"2015","journal-title":"Knee Surg Sports Traumatol Arthrosc"},{"key":"ref241","doi-asserted-by":"crossref","first-page":"9","DOI":"10.1016\/j.humov.2016.01.013","article-title":"Comparison of ankle kinematics and ground reaction forces between prospectively injured and uninjured collegiate cross country runners","volume":"47","author":"Kuhman","year":"2016","journal-title":"Hum Mov Sci"},{"key":"ref501","doi-asserted-by":"crossref","first-page":"7","DOI":"10.1123\/jsr.21.1.7","article-title":"Reliability of 2-dimensional video assessment of frontal-plane dynamic knee valgus during common athletic screening tasks","volume":"21","author":"Munro","year":"2012","journal-title":"J Sport Rehabil"},{"key":"ref221","doi-asserted-by":"crossref","first-page":"776","DOI":"10.1136\/bjsports-2016-096256","article-title":"Why screening tests to predict injury do not work\u2014and probably never will . . . : a critical review","volume":"50","author":"Bahr","year":"2016","journal-title":"Br J Sports Med"},{"key":"ref331","doi-asserted-by":"crossref","first-page":"250","DOI":"10.1016\/j.ptsp.2012.01.003","article-title":"Effects of a lower limb functional exercise programme aimed at minimising knee valgus angle on running kinematics in youth athletes","volume":"13","author":"Sheerin","year":"2012","journal-title":"Phys Ther Sport"},{"key":"ref261","doi-asserted-by":"crossref","first-page":"309","DOI":"10.1016\/j.knee.2015.04.012","article-title":"Contralateral limb deficit seven months after ACL-reconstruction: an analysis of single-leg hop tests","volume":"22","author":"Pairot de Fontenay","year":"2015","journal-title":"Knee"},{"key":"ref551","doi-asserted-by":"crossref","first-page":"642","DOI":"10.1136\/bjsports-2014-094094","article-title":"Clinician-friendly lower extremity physical performance measures in athletes: a systematic review of measurement properties and correlation with injury, part 1.
