Murtagh, CF, Brownlee, TE, O'Boyle, A, Morgans, R, Drust, B, and Erskine, RM. Importance of speed power in elite youth soccer depends on maturation status. J Strength Cond Res 32(2): 297-303, 2018-Maturation status is a confounding factor when identifying talent players (ESP). By comparing performance ESP control participants (CON) matched for status, the aims our study were to establish importance acceleration, sprint, horizontal-forward jump, vertical jump capabilities determining playing...
We investigated the association of multiple single nucleotide polymorphisms (SNPs) with athlete status and power/speed performance in elite male youth soccer players (ESP) control participants (CON) at different stages maturity. ESP (n = 535; aged 8-23 years) CON 151; 9-26 were genotyped for 10 SNPs grouped according to years from predicted peak-height-velocity (PHV), i.e. pre- or post-PHV, determine maturity status. Participants performed bilateral vertical countermovement jumps,...
This study examined if subjective wellbeing in soccer players was affected by match location, result and opposition quality before a (PRE), 1 day after (POST-1), 3 days (POST-3). Eleven professional male from the under 23 squad playing Premier League 2 division completed questionnaire 17 matches. Match training load (session-rating perceived exertion) not different, regardless of result, or faced (P > 0.05). Subjective different at PRE 0.05); however, POST-1 POST-3, stress mood were ≥20%...
Purpose: The aim of the study was to examine perceptions training data feedback from key stakeholders within coaching process professional soccer clubs.

Abstract Purpose To examine the prevalence of disordered eating (DE) in elite male and female soccer players influence perfectionism. Methods Using a cross-sectional design, ( n = 137) 70) non-athlete controls 179) completed clinical perfectionism questionnaire (CPQ-12) attitudes test (EAT-26) to assess DE risk, respectively. Results Male had higher EAT-26 scores than (10.4 ± 9.9 vs. 6.8 6.7; P 0.001), but there were no differences levels (EAT-26 score ≥ 20) (15 5%, respectively; X 2 0.079)...
The present study assessed changes in academy soccer players' perception of mental fatigue (MF) across a competitive season, investigating the relationship between MF and other subjective measures wellness. Ten players completed modified Brief Assessment Mood (BAM+) questionnaire that included question: "How mentally fatigued do you feel"? on match-day (MD) one (MD+1), two (MD+2) three (MD+3) days post-match (35 matches). Players reported their MF, along with (sleep, muscle soreness,...
Much less is known about strength and conditioning (S&C) practice in women's versus men's soccer. The aim of this study was to compare S&C between coaches working or soccer, at first team academy level, worldwide.A total 170 participants, who were involved with support their soccer club (in Europe, USA South America, within settings) completed a comprehensive online survey, designed evaluate (i) academic qualifications coaching experience; preferred methods for (ii) physical testing; (iii)...
McQuilliam, SJ, Clark, DR, Erskine, RM, and Brownlee, TE. The effect of high vs. moderate-intensity resistance training on strength, power muscle soreness in male academy soccer players. J Strength Cond Res 37(6): 1250-1258, 2023-The aims this study were to investigate the impact high-intensity, low-volume (HRT) vs . moderate-intensity, high-volume (MRT) only (control group [CON]) changes power, speed compare delayed onset (DOMS) between groups players (ASP). Twenty-two ASP (age: 18 ± 1...
It is currently unknown if injury risk associated with genetic variation in academy soccer players (ASP). We investigated whether nine candidate single nucleotide polymorphisms were (individually and combination) ASP at different stages of maturation. Saliva samples one season's records collected from 402 Caucasian male England, Spain, Uruguay, Brazil, whose maturity status was defined as pre- or post-peak height velocity (PHV). Pre-PHV COL5A1 rs12722 CC homozygotes had relatively higher...
The activities soccer players engage in during their formative years are thought to significantly contribute the acquisition of expert performance. Whilst this area has seen great interest male players, there been little research females. study examined developmental engaged by professional female England. 56 that had either progressed status adulthood (professional), or did not (ex-academy), completed Participant History Questionnaire. Professional started engaging at an earlier age than...
Purpose: The purpose of the present study was to record normative isometric maximum voluntary force (MVF) data at baseline and after an 8-week training period using mid-thigh pull (IMTP) for English Premier League academy players a maturation-matched control group.Methods: In total, 155 across under 9 21 age groups 93, maturation-, weight- height-matched participants performed IMTP. 142 62 elite cohorts respectively were retested 8 weeks later following integrated soccer or physical...
Growing evidence supports use of eccentric methods for strength development and injury prevention within elite soccer, yet uncertainty remains regarding practitioners' application flywheel (isoinertial) methods. The aims this study were to investigate how the training literature is perceived applied by soccer practitioners, highlight gaps in knowledge develop industry-relevant research questions. Fifty-one practitioners completed an electronic questionnaire. Fourteen Likert scale statements...
Purpose To determine whether training duration is a predisposing factor in potential maladaptations talent development programmes that promote early specialisation elite youth soccer. Methods Training times and type of 184 soccer players, from the under-9 to under-21 age groups (age 9.4 18.4 yrs; stature 1.38 1.82 m; body mass 32.2 76.2 kg) were recorded.
