The relationship between recovery and fatigue its impact on performance has attracted the interest of sport science for many years. An adequate balance stress (training competition load, other life demands) is essential athletes to achieve continuous high-level performance. Research focused examination physiological psychological strategies compensate external internal training loads. A systematic monitoring subsequent implementation routines aims at maximizing preventing negative...
Despite the perceived importance of sleep for elite footballers, descriptions duration and quality sleep, especially following match play, are limited. Moreover, recovery responses loss remain unclear. Accordingly, present study examined subjective footballers across training days (TD) both day night matches (DM NM). Sixteen top division European players from three clubs completed a online questionnaire twice 21 during season. Subjective recall variables (duration, onset latency, time...
The current study examined the sleep, travel, and recovery responses of elite footballers during after long-haul international air with a further description these over ensuing competitive tour (including 2 matches).In an observational design, 15 male football players undertook 18 h predominantly westward travel from United Kingdom to South America (-4-h time-zone shift) for 10-d tour. Objective sleep parameters, external internal training loads, subjective player match performance,...
Elite soccer players are at risk of reduced recovery following periods sleep disruption, particularly late-night matches. It remains unknown whether improving quality or quantity in such scenarios can improve post-match recovery. Therefore, the aim this study was to investigate effect an acute hygiene strategy (SHS) on physical and perceptual a match. In randomised cross-over design, two highly-trained amateur teams (20 players) played (20:45) friendly matches against each other seven days...
Research has demonstrated that induced mental fatigue impairs soccer-specific technical, tactical and physical performance in soccer players. The findings are limited by the lack of elite players low ecological validity tasks used to induce fatigue, which do not resemble cognitive demands soccer. current study collected survey data from English academy (n = 256; age groups - U14 U23), with questions comprising five themes (descriptors travel, education, match-play fixture congestion)....
The aim of this study was to investigate the occurrence repeated sprinting bouts in elite football. Furthermore, construct validity current tests assessing repeated-sprint ability (RSA) analysed using information sequences as they actually occurred during match-play. Sprinting behaviour official competition for 19 games German national team between August 2012 and June 2014. A threshold individually calculated based on peak velocity reached in-game sprinting. Players performed 17.2 ± 3.9...
Assessing current fatigue of athletes to fine-tune training prescriptions is a critical task in competitive sports. Blood-borne surrogate markers are widely used despite the scarcity validation trials with representative subjects and interventions. Moreover, differences between modes disciplines (e.g. due eccentric force production or calorie turnover) have rarely been studied within consistent design. Therefore, we investigated blood-borne during after discipline-specific simulated camps. A...
A cross-sectional analysis was performed to investigate associations between environmental temperatures and injury occurrence in two professional male football (soccer) leagues. Data from seven seasons of the German Bundesliga (2142 matches) four Australian A-League (470 were included. Injuries collated via media reports for team staff comprised incidence, mechanisms (contact, noncontact), locations (e.g., ankle, knee, thigh), types muscle tendon, joint ligament). Weather data included...
To analyze the reproducibility of pacing in elite swimmers during competitions and to compare heats finals within 1 event.Finals 158 male (age 22.8 ± 2.9 y) from 29 nations were analyzed 2 (downloaded swimrankings.net). Of these, 134 listed world's top 50 2010; remaining 24 finalists Pan Pacific Games or European Championships. The level both for analysis had be at least national championships (7.7 5.4 wk apart). Standard error measurement expressed as percentage subject's mean score (CV)...
Previous literature has presented pacing data of groups competition finalists. The aim this study was to analyze the patterns displayed by medalists and nonmedalists in international competitive 400-m swimming 1500-m running finals.Split times were collected from 48 finalists (four 100-m laps) 60 (4 competitions 2004 2012. Using a cross-sectional design, lap speeds normalized whole-race speed compared identify variations pace between nonmedalists. Lap-speed relative gold medalist for whole...
To investigate whether anthropometric profiles and fitness measures vary according to birth-date distribution in the German national youth soccer teams analyze there is a difference chance of becoming professional player depending on birth quarter (BQ).First, 554 players were divided into 6 age groups (U16-U21), each subdivided 4 BQs. Every performed at least one 30-m sprint, countermovement jump, an incremental test determine individual anaerobic threshold. For performing more than 1 within...
Assessments of executive functions (EFs) with varying levels perceptual information or action fidelity are common talent-diagnostic tools in soccer, yet their validity still has to be established. Therefore, a longitudinal development EFs high-level players understand relationship increased exposure training is required.A total 304 high-performing male youth soccer (10-21 years old) Germany were assessed across three seasons on various sport-specific and non-sport-specific cognitive...
To identify tactical factors associated with progression from preliminary rounds in middle-distance running events at an international championship.Results the 2012 Olympic Games were used to access final and intermediate positions, finishing times, season-best (SB) times for competitors men's women's 800-m 1500-m (fifteen races ten races). Finishing calculated as %SB, Pearson product-moment correlations assess relationships between positions. Probability (P) of qualification next round was...
The aim of the study was to investigate whether menstrual cycle phases influence physical performance during soccer match-play.Fifteen elite female players, with physiologically normal cycles, competed in matches over a four-month period. Physical assessed via GPS and expressed as meters per minute, separated into four individualised thresholds (low, high, very high sprinting). Seventy-six complete individual match observations, 36 from follicular 40 luteal phase were recorded. differences...
This study aimed at determining the reproducibility of pacing profiles (PP) during simulated swimming trials as well comparison between and real competitions (RC). Sixteen competitive front crawl swimmers (7 females, 9 males) performed 2 × 200 m, 400 m 800 tests, each test 7 days apart. All 100 split (ST) total times (TT) were recorded (additionally 50 ST for bouts). The PP one RC within a maximum 8 weeks before or after data acquisition was used comparison. No difference observed retest TT...
