‘I code as much as I can because you never know what they might ask for’. The role of the coach in Performance Analysis: The view of the analyst

Performance Analysis (PA) is viewed as an integral feature of soccer; however, the processes underpinning such practice are often described as simple, linear procedures. This fails to acknowledge the dynamism of PA and given increased investment and employment of analysts in professional soccer, scrutiny of the current processes and duties associated with the role would seem timely. To this purpose, eight full-time analysts in the English Football League (EFL) and English National League (National League) participated in in-depth semi-structured interviews and transcripts were subjected to inductive reflective thematic analysis. The data analysis revealed two higher-order categories (Flying solo / Coach control) and four themes classified as lower-order ( PA pragmatism / Identifying indicators / The reticent coach / Autocratic presentations). The findings of this study highlight that the responsibilities of the performance analyst range from acting on their own initiative to responding to requests and instructions from the coach. Subsequently, the responsibility for individual actions/activities related to PA is dependent on what aspects of analysis are to be used, who is the recipient of the data/video/presentation, when in the relationship between analyst and coach the activities are developed and when in the match-play process they are carried out.

English Premier League and English Football League academy managers’ experiences of how psychosocial skills and characteristics are identified and developed in youth academy soccer players

ABSTRACT Psychological skills and characteristics (PSCs) are vital for player development, yet there is a lack of agreement on which are important and how they should be identified and developed in academy players, creating barriers to implementation into curricula. The key stakeholder with considerable insight into PSC development is the academy manager (AM). The aims of this study were (a) explore AMs’ experiences of PSC identification and development, (b) identify challenges AMs feel affect development of PSCs. Nine AMs (i.e. Category 1; n = 3, Category 2; n = 3 and Category 3; n = 3) comprising an average coaching experience of 20.4 ± 7.4 years and time in the role of 5.2 years ±3.2 years participated in semi-structured interviews. Reflexive thematic analysis generated themes identified ideal PSC outcomes that AMs felt were important. AMs identified current practices within academies alongside challenges: transitions, need to upskill coaches, access to additional support from external partners and National Governing Bodies. There was consensus that PSCs are key drivers of progression and that embedding them into the pathway was critical to facilitating development. Academies should think carefully about design, implementation and evaluation of programmes to support player PSC development for success during and after soccer careers.

How is men’s mental health affected within male professional football?

ABSTRACT Research question How is men’s mental health affected within male professional football? Research methods Within this qualitative study, eighteen current first-team professional footballers were interviewed from across the English Football League (EFL) to explore how male professional footballers are affected by mental health. Braun and Clarke’s thematic analysis (2006) was applied along with “The Silences Framework” [Serrant-Green, L. (2010). The sound of “silence”: A framework for researching sensitive issues or marginalised perspectives in health. Journal of Research in Nursing, 16(4), 347–360] to allow the voices of this marginalised group to be heard. Results and findings The five key themes of social networks, environment, masking vulnerabilities, help-seeking and support, and mental health emerged from the data. The mental health theme is split into two sub-themes: impact on self and reaction of others. Implications This study makes an original contribution to the knowledge base as it is the first study to innovatively apply The Silences Framework to a sporting context. This study has applied The Silences Framework to show that professional footballers are affected by their mental health, and without appropriate access to support they continue to suffer in silence. This is likely to have negative consequences in their personal life, their football career, and their eventual transition away from being a professional footballer.

Analysis of external load in professional English Football League Two players

Previous research has utilised Global Positioning Systems (GPS) based technology to provide detailed insights on activity profiles and external demands of professional football. However, there remains minimal research exploring this in the English Football League (EFL), in particular, League Two. Considering differences such as a unique fixture frequency and congestion, and its impact of training occurrence, a study on the external physical loading of EFL League Two players is necessary. Furthermore, analysis of positional differences due to the varied activity profiles is warranted. Therefore, the aims of the current study were to explore the difference in the external demands across training mesocycles, and differences between four-, three-, or two-day training weeks. Additionally, positional differences in external demands in competitive fixtures were explored. Twenty, male, professional soccer players from the EFL League Two (27 ± 6 years, mass 81 ± 8 kg, stature 181 ± 8 cm) were monitored across 41 competitive matches during the 2023-24 season. Players were grouped into the following positional categories central defender (n=3); wide defender (n=4); central midfielder (n=5); wide midfielder (n=5) and striker (n=3). The ethics committee of the sport department at University Academy 92 approved this study. A GPS system (Apex, STATSports, Northern Ireland) was used to quantify external load data from training and match day (MD) across 5 mesocycles of the season. Total distance ranged from 92.1 ± 6.5 m·min-1 to 106.2 ± 8.7 m·min-1 and 44.0 ± 2.0 m·min-1 to 56.8 ± 4.9 m·min-1 across mesocycles in matches and training, respectively. Likewise, High-Speed Running also varied across mesocycles, ranging from 5.6 ± 1.9 m·min-1 to 6.7 ± 1.0 m·min-1 and 0.9 ± 0.3 m·min-1 to 1.3 ± 0.4 m·min-1 in matches and training, respectively. Significant differences (p < 0.05) in several external load variables were evident between four-, three-, or two-day training weeks. When analysing positional differences in matches, the CM achieved the greatest total distance (106.3 ± 17.6 m·min-1), with WM exhibiting the greatest amount of distance at high speed (7.9 ± 2.1 m·min-1) and total accelerations and decelerations (1.9 ± 0.3 ·min2; 1.0 ± 0.3 ·min2). Consequently, results from this research should allow practitioners to physically prepare players optimally in preparation for MD. In conclusion, this study highlighted that external match load performance was influenced by players' positions. Moreover, the consideration of training days in preparation for a fixture, might allow players to be in optimum physical capacity for MD.

On-field rehabilitation in football: current practice and perceptions. A survey of the English Premier League and Football League

ABSTRACT Introduction Return to play related research is increasing rapidly, with two recent competency-based frameworks offering conceptualised support for on-field rehabilitation (OFR) decision-making. It is still unknown, however, who is responsible for OFR and how they typically select, monitor, and progress OFR processes. Aims The purpose of this study was to investigate current OFR practice within English professional football to support practitioners with decision-making and highlight opportunities for future research related to the design, monitoring, and progression of OFR. Methods Sixty-nine practitioners responsible for the design and implementation of OFR at 69 clubs (75% of the English Premier League and Football League) responded to a survey containing 30 questions (14 open and 16 closed). Results The main findings were that therapists (physiotherapists/sports therapists) have the largest influence on OFR, followed by physical performance coaches (sports scientists/strength and conditioning coaches), technical coaches and medical doctors. There was more agreement for the ordering of specific OFR drills earlier in the process when activities are easier to control. The most frequently reported objective monitoring tool was global positioning systems (GPS), with functional/clinical experience/expertise remaining subjectively vital. GPS outputs (e.g., sprint metrics and accelerations/decelerations) were most used for between session decision-making, with verbal communication being key for within session decision-making. Conclusion Future research should use evidence of current practice, such as drill design and monitoring techniques, to explore drill-level analysis and give practitioners greater insights into which stage of current OFR frameworks specific drills fall, and how they might be more objectively progressed/regressed.

Dear Prime Minister, Mr Musk and Mr Zuckerberg!: The challenge of social media and platformed racism in the English premier league and football league

This paper draws on original research from a larger study of racism and Islamophobia online around football, particularly a set of interviews with staff at English football clubs whose responsibility is to manage social media. We use that information alongside our reflections on “platformed racism” to appraise how expressions of racism on social media differ from those in and around the grounds, and how clubs and others in football contest them. This involves a consideration of three themes commonly identified by those speaking on behalf of the clubs: The triggers that ignite racist posts; the partnerships necessary to counter them; and their proposed solutions. Hence this is not just a cue for a collective wringing of hands, but an effort to point the way forward.

The S-Score of Financial Sustainability for Professional Football Clubs

This article extends the extensive literature on business failure and develops the approach of Altman to provide quantified recommendations for the financial sustainability of football clubs. The article uniquely identifies four scenarios that have caused insolvency for football clubs in the English Football League (EFL) and uses multiple discriminant analysis to identify financial models that delineate between professional football clubs that experience insolvency events and those that do not. These models produce an S-score which is introduced to suggest minimum financial tolerances for accounting ratios that provide a reasonable level of resilience for the financial sustainability of clubs in each scenario. The results are relevant for academics and non-academics with an interest in the business of football, professional football clubs aiming to avoid financial distress, and specifically, the Regulator that the U.K. government has proposed for football in England.

The marketing of season tickets in the English Football League during a cost-of-living crisis: the importance of financial sustainability and the role of economic, social and cultural capital

ABSTRACT English Football League (EFL) clubs rely on season ticket (ST) sales as an annual revenue source. ST sales during the cost-of-living crisis in 2022 theoretically took on more importance given clubs’ rising operating costs. Conversely, supporters may have faced a difficult choice in purchasing or renewing STs. This paper – through a Critical Realist approach – explores how the importance of financial sustainability was represented in the ST marketing deployed by EFL clubs ahead of the 2022/2023 season. The online ST-related promotional material of 71 EFL clubs was thematically analysed. Key themes consisted of economic mitigations, the importance of the supporter base, and the value promised to supporters. Retroduction uncovered a ST sales structure which unifies EFL clubs and supporters, between whom economic, social, and cultural capital are continuously exchanged. These forms of capital generate economic revenue for EFL clubs, and elevation within the supporter habitus for ST holders.

Football finance and Covid-19

This study looks at the financial performance of top English football clubs to understand the impact of the Covid-19 pandemic. Our analysis focuses on English Premier League (EPL) and English Football League (EFL) clubs that have participated at least once in England’s highest league, the EPL. Using panel data methodology from 36 clubs between 2005 – 2021, we quantify the impact and severity of Covid-19 on top English football clubs’ financial performance. We find statistically significant evidence that profitability deteriorated during the pandemic with EPL clubs more reliant on matchday revenue the most impacted. Both financial stability and indebtedness deteriorated during the pandemic but the deterioration was not statistically significant. EFL clubs were the most impacted by reduced financial stability and increased indebtedness. These findings are vital for football’s regulators as it provides empirical evidence on the stability of the industry and also provides insights football club owners on strategies they can adopt to survive during external shocks to the industry

A Comparison of Training and Match Play External Load During a Congested In-Season Period in English League 2 Football.

Fleming, A, Walker, M, Armitage, M, Connor, M, and Beato, M. A comparison of training and match play external load during a congested in-season period in English League 2 Football. J Strength Cond Res 37(9): e527-e534, 2023-This study aimed to investigate if external training load metrics differ between training days and match day (MD) during a period of fixture congestion and to verify if external load metrics vary based on playing positions. Training and MD data were collected in a part of the competition phase of the 2020-2021 season (6 weeks) in the English Football League 2 ( N = 20 players, mean ± SD s: age = 24.4 ± 4.7 years). Global Navigation Satellite System units (Catapult S7 Vector 10 Hz) were used to monitor external load metrics. The metrics were duration of training, total distance (TD), high-speed running distance (HSR), sprinting distance, relative intensity (m/min), total accelerations (TotAcc) (>3 m·s -2 ), and total decelerations (TotDec) (<-3 m·s -2 ). This study found that duration, TD, relative intensity, HSR distance, sprint distance, TotAcc, and TotDec were different ( p < 0.001, d = small to moderate ) between MD and match day minus two (MD-2) or match day minus one (MD-1); however, during match day minus four (MD-4), only relative intensity was significantly lower ( p < 0.001) compared with MD output. Therefore, MD-4 was the most demanding training session of the week (after the MD), and during MD-2 and MD-1, coaches decreased players' load to favor players' readiness. Moreover, this study found that MD and MD-1 resulted in statistically different values across several metrics between different playing positions (defenders < midfielders and strikers), whereas metrics in MD-4 and MD-2 were not statistically different, which highlights that in these sessions, players have similar external loads independently from their playing positions.

Does Foreign Investment Affect Sporting and Managerial Efficiency? The Case of English Football Clubs

Abstract: The number of foreign owners in football clubs has recently increased in Europe and especially in England. This study aims to analyze whether clubs owned by foreign investors show different parameters of sporting and managerial efficiency. We use data on expected performance (from betting odds), wage costs, and the results of football clubs in the English Premier League (EPL) and English Football League Championship (EFL) over 13 seasons. We estimate different measures of efficiency using three alternative methods: expected vs. actual performance index, nonparametric conditional data envelopment analysis (DEA), and stochastic frontier, while considering foreign ownership as an exogenous factor. Our results suggest that there are not significant differences between domestic- and foreign-owned clubs.

The Relationship between Acute: Chronic Workload Ratio of High-Speed Running and Hamstring Injuries in Professional Footballers

Hamstring strain injuries are common within professional footballers with high-speed running (HSR) being known to increase the likelihood of sustaining a hamstring injury. This study aimed to assess the acute: chronic workload ratio (ACWR) of HSR that preceded hamstring injuries in professional footballers. Global positioning system (GPS)-derived HSR distances and weekly ACWR were obtained from 18 footballers from one English Football League (EFL) club during the 2018-2019 season. Hamstring injuries were documented by the club’s medical team and the ACWR data of the four weeks preceding each hamstring injury were analysed. The mean ACWR of injured players was calculated for each season along with the ACWR of the squad. Ten hamstring injuries were recorded in total, across eight of the 18 players (44%). The most common site of injury was the medial part of the hamstring (70%). At the time of injury the mean ACWR for injured players was 0.90, while the squad mean ACWR for the season was 1.04. In conclusion, this study evidenced a high prevalence of non-contact hamstring injuries over a competitive season within an EFL club. The majority of hamstring injuries occurred when the mean ACWR was below the squad mean ACWR for the season. The loading pattern of ‘moderate to high’ followed by ‘low to moderate’ ACWR was commonly observed in the four weeks prior to injury.

What Does It Mean to Be “Competitive”? Using Simulation to Reveal Competitive Balance in English Association Football

Abstract: This paper illustrates the value of using betting data to simulate an ex-ante distribution of league-point outcomes for English professional association football. Competition in the three tiers of the English Football League (EFL) is much more balanced than in the English Premier League (EPL). The competition at the top of the tables is more concentrated than at the bottom of the tables. Clubs relegated into a lower league tend to perform well the next season. Still, this effect does not seem to be impacted by parachute payments given to those relegated from the EPL into the second division.

The Performance Effects of Internal Resource Redeployment versus External Resource Sourcing

The reconfiguration of strategically important resources through internal redeployment or sourcing from the external market is a vital aspect of corporate development. However, empirical studies that directly ascertain the relative performance of internal resource redeployment over acquiring/borrowing resources on the external market are lacking. We overcome the empirical challenges associated with comparing the effectiveness of both reconfiguration modes by examining the redeployment of human resources—professional soccer players in the English Football League Championship—following a significant injury to a key player. This approach further allows us to develop theory regarding the roles of important resource-level characteristics, including fungibility and similarity, and to circumvent endogeneity issues related to the resource reconfiguration-performance relationship. This study thereby extends existing theory and produces novel findings that illuminate the importance of resource-level characteristics as drivers of the relative performance advantages of different reconfiguration modes. We discuss implications for the literature on resource reconfiguration and strategic human capital.

Gambling in professional sport: the enabling role of “regulatory legitimacy”

PurposeThis study aims to explain why organisations remain vulnerable to financial failure despite increasing financial regulation to improve governance. Using a case study of gambling and regulation in professional football in England, it introduces the concept of “regulatory legitimacy” to show how this enables football clubs to gamble.Design/methodology/approachThe study quantifies the extent to which football clubs in the Championship of the English Football League (EFL) adopt a conventionally economically irrational decision to run a loss-making budget in the hope of achieving sporting success. The study postulates criteria for evidence of this form of gambling by overspending on playing talent with data from the clubs’ published financial statements. A pay-off matrix is developed to compare the intended and actual outcomes.FindingsThe research finds that this strategy was both prevalent and the most successful to achieve promotion.Originality/valueThis study makes three contributions. The first is the quantification of the prevalence of this form of gambling. The second is the finding that, despite regulations to limit spending on wages, gambling is rational in the non-economic sense because it is almost a necessary strategy to achieve promotion if the club had not been relegated from the Premier League in the previous season. The third contribution is the development of the concept of “regulatory legitimacy” as a way to understand the process through which regulations are implemented yet are ineffective at curbing financial gambling.

Maturity Has a Greater Association than Relative Age with Physical Performance in English Male Academy Soccer Players.

This study aimed to: (1) examine differences in physical performance across birth-quartiles and maturity-status, and (2) determine the relationships among relative age, maturation and physical performance in young male soccer players. The sample included 199 males aged between 8.1 and 18.9 years, from two professional soccer academies in the English Football League. Data were collected for height, weight, self-reported biological parent heights, 30 m sprint time and countermovement jump (CMJ) height. Relative age was conveyed as a decimal, while maturity status was determined as the percentage of predicted adult height (PAH). There were no significant differences in any measure between birth quartiles, however early maturers outperformed on-time and later maturers in most performance measures. Pearson-product-moment correlations revealed that maturation was inversely associated with 30 m sprint time in U12 to U16 (r = −0.370–0.738; p < 0.05), but only positively associated with CMJ performance in U12 (r = 0.497; p < 0.05). In contrast, relative age was unrelated to sprint performance and only significantly associated with superior CMJ performance in U16. This study indicates that maturity has a greater association with sprint performance than relative age in English male academy soccer players. Practitioners should monitor and assess biological maturation in young soccer players to attempt to control for the influence on physical performance, and avoid biasing selection on absolute performance rather than identifying the most talented player.

Epstein–Barr Virus (EBV) DNA as a Potential Marker of in vivo Immunity in Professional Footballers

ABSTRACT Introduction: Team sport athletes have increased susceptibility to upper respiratory symptoms (URS) during periods of intensified training and competition. Reactivation of Epstein–Barr Virus (EBV) may be a novel marker for risk of upper respiratory illness (URI) in professional athletes. Aims: To investigate changes in salivary EBV DNA (in addition to the well-established marker, salivary secretory immunoglobulin A), and incidence of URS in professional footballers. Methods: Over a 16-week period (August to November 2016), 15 male players from a professional English football League 1 club provided weekly unstimulated saliva samples (after a rest day) and recorded URS. Saliva samples were analyzed for secretory IgA (ELISA) and EBV DNA (qPCR). Results: Whole squad median (interquartile range) saliva IgA concentration and secretion rate significantly decreased (p < .05) between weeks 8 and 12 (concentration, 107 (76–150) mg/L healthy baseline to 51 (31–80) mg/L at week 12; secretion rate 51 (30–78) µg/min healthy baseline to 22 (18–43) µg/min at week 12). Two players reported URS episodes during week 10, both after IgA secretion rate decreased below 40% of the individual’s healthy baseline. EBV DNA was detected in the weeks before URS but also at other times and in healthy players (overall frequency 40%, range 11–78%) and frequency was similar between the URS and healthy group. Conclusion: These findings confirm salivary IgA as a useful marker of URS risk but EBV DNA was not. Further research capturing a greater number of URS episodes is required, however, to fully determine the utility of this marker.

The simple, conventional markers of fatigue - variations in neuromuscular performance, creatine kinase and hydration status in elite soccer players over a season.

Background and Purpose: Fixture congestion, game-intensities and limited recovery negatively influence physical/physiological responses during a competitive soccer season. Therefore, the aim of the investigation was to examine weekly alterations in neuromuscular performance markers, creatine kinase and hydration in elite soccer players throughout a season. Study Design: Longitudinal Observational Study. Methods: Sixteen male professional soccer players competing in the English Football League Championship were assessed over the course of a season. All players provided a urine sample, a blood sample to assess creatine-kinase concentration and performed a countermovement jump test at the start of the season, in-season, pre-and post-match over 38 weeks. Results: Jump height was the most common marker of performance to be significantly reduced in-season compared to baseline (-5.4 to -11.3%, P&lt;0.05) with 45.2% of the time-points affected. Measures of FT:CT (-7.5 to -12.4%) and AP (-9.4 to -11.5%), also showed significant deteriorations throughout the season compared to baseline (P&lt;0.05) at several time-points. Max force (MF) significantly increased in-season (+5.1 to 7.0%) in 20% of the observed time-points compared to baseline. CK concentration significantly increased during 19% of the time-points (P&lt;0.05; 62 to 159%). Urine osmolality demonstrated significant differences in season compared to baseline, but none to levels of dehydration. Conclusion: Monitoring elite soccer players over the course of a competitive season shows alterations in neuromuscular performance and hydration status. These data suggest that assessing counter-movement jump performance may be a useful marker for monitoring responses to training/competition, while creatine-kinase and hydration status may be limited.

The Effect of High-Intensity Accelerations and Decelerations on Match Outcome of an Elite English League Two Football Team.

Objectives: Previous research has highlighted the frequency of high-intensity accelerations and decelerations in elite football. The influence of these actions on match performance outcomes has not been established. The aim of the present study was to identify the influence of high-intensity accelerations and decelerations on match performance outcomes (i.e., win, draw, lost). Comparisons were also made between team and positional high-intensity accelerations and decelerations recorded within the games. Methods: 26 elite outfield footballers from an elite English Football League (EFL) Two team completed the present study. Global Positioning System (GPS) technology was utilised to quantify high-intensity accelerations and decelerations during 45 games in a competitive season. Magnitude analysis and the effects of results, positions and fixture periods were observed. Results: Significant effects of results, periods and positions were observed (p ≤ 0.05), with the highest outputs observed in games won. Positionally, fullbacks and centre forwards in a 4–3–3 formation exhibited the greatest frequency of high-intensity accelerations and decelerations. Very large differences were observed between the frequency of high-intensity decelerations compared to accelerations in games won (g = 2.37), drawn (g = 2.99) and lost (g = 3.59). The highest team frequencies of high-intensity accelerations (n = 3330) and decelerations (n = 6482) were completed in games won. Conclusions: The frequency of high-intensity accelerations and decelerations has a significant impact on match performance outcomes in an elite English League Two football team. Consideration needs to be given to specific conditioning and recovery strategies to optimise high-intensity acceleration and deceleration performance in games. Caution should be taken as these findings are representative of one team within the EFL.

Monitoring Postmatch Fatigue During a Competitive Season in Elite Youth Soccer Players.

Countermovement jump (CMJ) and perceived wellness measures are useful for monitoring fatigue. Fatigue indicators should simultaneously show sensitivity to previous load and demonstrate influence on subsequent physical output; however, these factors have not been examined. To explore the efficacy of CMJ and wellness measures to both detect postmatch fatigue and predict subsequent physical match output in elite youth soccer players. Cross-sectional study. Sixteen soccer players (18 ± 1 years) from 36 English Football League Youth Alliance League fixtures. Physical match outputs (total distance, high-speed running, very high-speed running, and accelerations and decelerations [AD]) were recorded using a 10-Hz global positioning system and 200-Hz accelerometer device during competitive match play. The CMJ height and perceived wellness were assessed weekly and daily, respectively, as indirect indicators of fatigue. Four subunits of wellness (perceived soreness, energy, general stress, and sleep) were measured using customized psychometric questionnaires. Simple linear regression showed that match AD predicted energy (R2 = 0.08, P = .001), stress (R2 = 0.09, P < .001), and total wellness (R2 = 0.06, P = .002) at 2 days postmatch. The CMJ (R2 = 0.05, P = .002), stress (R2 = 0.08, P < .001), sleep (R2 = 0.03, P = .034), and total wellness (R2 = 0.05, P = .006) measures at 5 days prematch predicted AD during the subsequent match. The CMJ and wellness measures may be useful for detecting postmatch fatigue. Wellness scores, but not CMJ, at 5 days prematch influenced subsequent match output and therefore may be used to plan and periodize training for the upcoming microcycle.
