Muscle glycogen is the predominant energy source for soccer match play, though its importance training (where lower loads are observed) not well known. In an attempt to better inform carbohydrate (CHO) guidelines, we quantified load in English Premier League players (n = 12) during a one-, two- and three-game week schedule (weekly frequency was four, four two, respectively). one-game week, progressively reduced (P < 0.05) 3 days prior day (total distance 5223 ± 406, 3097 149 2912 192 m 1, 2...
To quantify the accumulative training and match load during an annual season in English Premier League soccer players classified as starters (n = 8, started ≥60% of games), fringe 7, 30-60% games) nonstarters 4, <30% games). Methods Players were monitored all sessions games completed 2013-14 with quantified using global positioning system Prozone technology, respectively.When including both matches, total duration activity (10,678 ± 916, 9955 947, 10,136 847 min; P .50) distance covered...
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 <...
The complexity of the physical demands soccer requires completion a multi-component training programme. development, planning, and implementation such programme are difficult due partly to practical constraints related competitive schedule at top level. effective planning organisation therefore crucial delivery stimulus for both individual players team. aim this article is provide an overview principles that can be used prepare soccer. Information relating periodisation supported by outline...
We examined the effects of an intensive fixture schedule on salivary IgA (SIgA) concentration in professional soccer players from English Premier League. Salivary samples were obtained 21 males who participated seven games over a 30-day period during December 2013 and January 2014 (games 1-5 occurred 15-day period). Salivary-IgA decreased (P < 0.05) at 2 days post-game 3 (45 ± 9 μg mL(-1)), 4 (52 mL(-1)) 5 (41 10 compared with game 1 (139 25 mL(-1)). When normal resumed (i.e. one per week),...
The present study aimed to assess the physical match performance among senior and youth soccer players from an elite Scottish Premiership club during 2021/2022 season. Twenty-two first team (25.9 ± 4.5 years, 78.3 8.2 kg, 1.82 0.07 cm) 16 (16.8 0.9 70.1 6.8 177 5.8 were examined. A selection of variables measured using a global positioning system. Linear mixed-effect regressions revealed for all examined no significant differences between U-18 playing level by position interaction. Across...
The technical and physical demands of elite soccer match-play may vary considerably across a season from season-to-season in relation to myriad factors. aim this study was investigate the performance trends over five consecutive seasons (2016–2021) for twenty-two players team participating an European league, Russian Premier League (RPL). Match data were recorded analysed via Optical Tracking System, selection variables examined. From matches analysed, we observed small within-season changes...
To investigate if maturity status was associated with injury risk in male academy soccer players.Prospective cohort surveillance study.Professional academies.501 players (aged 9-23 years) from eight academies England, Spain, Uruguay and Brazil.Players were grouped by offset as pre-peak height velocity (PHV), circa-PHV, post-PHV or adult. Injury prevalence proportion (IPP) days missed recorded for one season per player, training/match exposure a sub-sample (n = 166).IPP all injuries combined...
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...
This study aimed to examine the salivary immunoglobulin A (s-IgA) and cortisol (s-Cort) responses competitive matches in elite male soccer players. Data were collected for 19 players (mean ± SD, age: 26 4 years; weight: 80.5 8.1 kg; height: 1.83 0.07 m; body-fat 10.8 0.7%) from a Russian Premier League team throughout 6-week period during 2021-2022 season. Physical match loads measured through an optical tracking system. s-IgA s-Cort assessed one day before each (MD - 1), 60-min kick-off,...
Introduction: The aims of this study were to: a) investigate salivary immunoglobulin A (s-IgA) and cortisol (s-Cort) responses to nine competitive fixtures in starting non- soccer players; b) compare s-IgA s-Cort starters non-starters considering match outcome. Methods: Saliva from 19 male outfield players an elite team (mean ± SD, age 26 4 years; weight 80.5 8.1 kg; height 1.83 0.07 m; body-fat 10.8% 0.7%) was collected. samples taken on the day before each (MD-1), 60-min kick-off (MDpre),...
Whether playing position influences injury in male academy soccer players (ASPs) is unclear.To determine if was associated with ASPs.Descriptive epidemiology study.English, Spanish, Uruguayan, and Brazilian academies.A total of 369 ASPs from the under-14 to under-23 age groups, classified as post-peak height velocity using maturity offset, grouped goalkeepers, lateral defenders, central midfielders, or forwards.Injuries were recorded prospectively over 1 season. Injury prevalence proportion...
BACKGROUND: The technical and physical performance, a key part of overall soccer tend to evolve due changes in game rules, playing styles, training methodology. Nevertheless, little has been reported the literature on how match performance changed over time elite championships leagues. Thus, this study aimed assess impact selected team indicators outcome five seasons Russian Premier League.METHODS: Twenty-two variables, recorded with an optical tracking system, were examined 1186 matches...
The present study examined the effect of acute caffeine ingestion (150 mg) on physical performance elite European soccer players during official competitive match-play. current investigation was a parallel-group design that collated data from cohort 19 male outfield an team (mean ± SD, age 26 4 years; weight 80.5 8.1 kg; height 1.83 0.07 m; body-fat 10.8 0.7%). Players were classified and matched by position grouped accordingly: centre defender (CD) n = 5, wide (WD) 3, midfield (CM) 7,...
