The study assessed the intra-week reliability of one-foot or two-foot approach jumps within youth basketball athletes. In a test-retest design, 108 athletes (33 females and 75 males) performed maximal jump reach height assessment using both strategies following self-selected run-up. Data were collected Vertec system across two sessions, separated by >24 hours <7 days. Results analysed for bias differences between tests, focussing on absolute (SEM) relative (ICC) reliability; with statistical...
To investigate the effect of early evening exercise training at different intensities on nocturnal sleep and cardiac autonomic activity in endurance-trained runners.Eight runners completed three experimental trials a randomised, counterbalanced order. In (end 3.5 h before bedtime), participants performed either: (i) 1 high-intensity interval running session (HIGH, 6 × 5 min 90% VO2peak interspersed with recovery); (ii) low-intensity (LOW, 60 45% VO2peak) or (iii) no (CON). Subsequent was...
Abstract During the competitive season, soccer players are likely exposed to numerous factors that may disrupt process of sleep. The current investigation looked evaluate a practical sleep hygiene strategy (10‐min showering at ∼40°C before lights out), within group 11 youth in comparison normal sleeping conditions (control). Each condition consisted three days randomised crossover trial design. Sleep information was collected using commercial wireless bedside monitor. Measures skin...
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...
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...
The current study compared sleep characteristics of youth soccer players (N = 12, 19 ± 1 years) with non-athletes =12, 23 3 over a period six nights using wireless electroencephalogram monitor. This device provided breakdown the participant’s schedule, latency, duration and awakenings. Participant mean SD were calculated across to form between group comparisons (i.e., independent t-tests, Mann–Whitney–Wilcoxontests effect sizes [ESs]). displayed longer durations than (+64 min; ES: 1.39; P <...
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...
Abstract The current study examined how sleep may be influenced by the scheduling of training and match load within 10 youth‐soccer players. Sleep was measured over a 14‐day in‐season period using commercially available wireless monitor. Each collected variable; lights out, latency, total time wake after onset final awakening, compared for specific day schedule (e.g. [MD], [MD + 1]) to training/match (high‐speed distance (>5.5 m/s) [HSD] rating perceived exertion. data were analysed mixed...
Purpose The aim of this case report was to describe the sleep responses in a male combat sport athlete, who engaging both chronic (CWL) and acute (AWL) weight loss practices order reduce body mass for national competition. Methods During first seven weeks training (Phases 1 2), athlete adhered daily energy intake (EI) equating their resting metabolic rate (1700 kcal·day −1 ) followed by reduction EI (915–300 5 days before weighing (Phase 3). Nocturnal monitored throughout 8-week period using...
Abstract Wannouch, YJ, Leahey, SR, Whitworth-Turner, CM, Oliver, JL, YH, KC, Laffer, JC, and Leicht, AS. A comprehensive analysis of 10-yard sprint reliability in male female youth athletes. J Strength Cond Res 38(9): e477–e488, 2024—This study investigates the inter-week test–retest 9.14 meter (10 yard) times Although essential for assessing athletic ability training efficacy, critical examination both relative absolute indices short-distance sprints has been insufficient contexts.

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...
Purpose : (1) To compare the sleep of female players from a professional soccer team to nonathlete controls across an in-season week and (2) core fringe same on night after match training nights. Methods Using observational design, 18 were monitored for their via wristwatch actigraphy 1 week. Independent-sample t tests Mann–Whitney U performed between groups, while analysis variance compared nights match. Results Soccer had significantly greater duration than (+38 min; P = .009; d 0.92),...
