In an attempt to better identify and inform the energy requirements of elite soccer players, we quantified expenditure (EE) players from English Premier League (n = 6) via doubly labeled water method (DLW) over a 7-day in-season period. Energy intake (EI) was also assessed using food diaries, supported by remote photographic 24 hr recalls. The period consisted 5 training days (TD) 2 match (MD). Although mean daily EI (3186 ± 367 kcals) not different (p > .05) EE (3566 585 kcals), greater <...
Professional soccer players from the first team (1st team, n = 27), under twenty-one (U21, 21) and eighteen (U18, 35) squads of an English Premier League were assessed for whole body regional estimates composition using dual-energy X-ray absorptiometry (DXA). Per cent fat was lower in 1st (10.0 ± 1.6) compared with both U21 (11.6 2.5, P 0.02) U18 (11.4 2.6, 0.01) players. However, this difference not due to variations (P 0.23) mass between (7.8 1.6 v. 8.8 2.1 8.2 2.4 kg, respectively) but...
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%...
The daily distribution of macronutrient intake can modulate aspects training adaptations, performance and recovery. We therefore assessed the (as using food diaries supported by remote photographic method 24-hr recalls) professional soccer players ( n = 6) English Premier League during a 7-day period consisting two match days five days. On days, average carbohydrate (CHO) content prematch (<1.5 g·kg -1 body mass) postmatch (1 meals (in recovery from an evening kick-off) were similar p...
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)...
While traditional approaches to dietary analysis in athletes have focused on total daily energy and macronutrient intake, it is now thought that distribution of these parameters can also influence training adaptations. Using 7-day food diaries, we quantified the intake elite youth soccer players from English Premier League U18 (n = 13), U15/16 25) U13/14 squads 21). Total (43.1 ± 10.3, 32.6 7.9, 28.1 6.8 kcal·kg-1·day-1), CHO (6 1.2, 4.7 1.4, 3.2 1.3 g·kg-1·day-1) fat (1.3 0.5, 0.9 0.3, 0.3...
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,...
The aim of this investigation was to profile the physiological, physical, and biomechanical responses during walking football. A total 17 male participants (aged 66 ± 6 years) participated. Heart rate; blood lactate; accelerometer variables (biomechanical load [PlayerLoad™], changes direction); rating perceived exertion were measured. Participants mean percentage maximum heart rate 76 6% sessions, with across all sessions at 13 2. Blood lactate increased by ∼157% from presession (1.24 0.4...
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...
In this study, the nutritional and recovery habits of tennis players pre-, during, post-match-play were investigated. Seventy completed a bespoke nutrition questionnaire, with questions related to following areas: match preparation, intra-match habits, situation dependent variables, post-match recovery. On day-1, consumption balanced meals consisting carbohydrate (CHO), fat protein, some micronutrient considerations reported by 51% players. match-days, CHOs prioritised prior match-play CHO...
Abstract This study examined the influence of injury, match selection and training load on mental wellbeing (MW) in a squad professional soccer players. Using longitudinal design, twenty-five male players (age, 20 ± 1 years, height, 1.80 5.79 m, body mass 76.33 7.52 kg) from under 23 playing Premier League 2 division UK completed Warwick-Edinburgh Mental Well-being Scale (WEMWBS) each week 2017/2018 season (37 weeks total). Injury non-selection for were only significant predictors MW (P <...
1 The effects of infusions frusemide at low (0.05–0.1 mg.kg-l, min-1) and high (0.5–2.0 mg.kg-1.min-1) rates were studied on renin secretion urinary outputs sodium potassium in anaesthetized dogs which one kidney was removed the remaining either innervated or denervated. 2 When innervated, infusion did not significantly affect if volume losses replaced. Without replacement losses, increased deficits 0.7–0.9 mmol.kg-1 presence elevated excretion. 3 High caused an immediate increase from...
The influence of a match including extra-time (ET) on subsequent 90 min performance and recovery has not been investigated. Four professional soccer players played in three competitive matches 7-day period: one (MD1) (MD3) lasted 2 (MD2) 120 (i.e., included ET). Physical (total high-intensity (HI) distance covered, accelerations decelerations, mechanical load) technical performances (pass dribble accuracy) were analyzed throughout match-play. Subjective measures countermovement jump (CMJ)...
The powerful activity profile of elite soccer match play has not been documented appropriately to inform specific maximal power assessment and development criteria. aims the current study were develop a reliable soccer-specific action (SSPA) notational analysis coding system that could be used compare frequency durations actions during youth play.Sixteen male English Premier League (EPL) Academy players (19 ± 1 yrs) recorded by an individual camera 16 competitive EPL U18 U21 games.

Purpose: The purpose of the study is to investigate biomechanical and physiological responses soccer-specific exercise incorporating an extra-time period (ET) assess test–retest reliability these responses. Methods: Twelve soccer players performed 120 min exercise. Tri-axial (PLTotal) uni-axial PlayerLoad™ in vertical (PLV), anterior–posterior (PLA–P), medial–lateral (PLM–L) planes were monitored using a portable accelerometer. Likewise, respiratory exchange ratio (RER) was recorded...

Introduction There has been an abundance of dietary analysis research conducted on adult male soccer players, while studies youth players are lacking. Furthermore, the daily distribution energy and macronutrient intake throughout day reported to influence training adaptations, but this is often not considered in literature. This study aims quantify assess their over 5 days, compare intakes predicted expenditure under-16 players. Methods The sample included 25 participants aged 14.8–15.7...
