Abstract Hand grip strength is a widely used proxy of muscular fitness, marker frailty, and predictor range morbidities all-cause mortality. To investigate the genetic determinants variation in strength, we perform large-scale discovery analysis combined sample 195,180 individuals identify 16 loci associated with ( P <5 × 10 −8 ) analyses. A number these contain genes implicated structure function skeletal muscle fibres ACTG1 ), neuronal maintenance signal transduction PEX14, TGFA, SYT1...

Objectives: This study aimed to assess how menstrual cycle phase and extended length influence the incidence of injuries in international footballers. Methods: Over a 4-year period, from England footballers at training camps or matches were recorded, alongside self-reported information on characteristics point injury. Injuries eumenorrheic players categorized into early follicular, late luteal phase. Frequencies also compared between recorded during typical those that occurred after would be...

Abstract Objectives To determine the incidence and characteristics of injury illness in English men’s women’s senior youth international football. Methods Time-loss injuries illnesses, alongside match training exposure, were collected across 8 seasons (2012–2020) (U15, U16, U17, U18, U19) (U20, U21, U23, senior) teams. Analysis incidence, burden, severity was completed. Sex-specific comparisons made between groups, data collection. Results In football, 535 recorded (216 senior; 319 youth)...

Habitual football participation has been shown to be osteogenic, although the specific volume of required cause bone adaptations are not well established. The aim present study is investigate tibial in response 12 weeks increased training elite adolescents who already accustomed irregular impact training. 99 male adolescent footballers participated (age 16±0 y; height 1.76±0.66 m; body mass 70.2±8.3 kg). Tibial scans were performed using peripheral quantitative computed tomography...

Bone resorption is increased after running, with no change in bone formation. Feeding during exercise might attenuate this increase, preventing associated problems for bone. This study investigated the immediate and short-term metabolic responses to carbohydrate (CHO) feeding treadmill running. Ten men completed two 7-day trials, once being fed CHO (8% glucose immediately before, every 20 min during, at a rate of 0.7 g CHO·kg body mass −1 ·h ) placebo (PBO). On day 4 each trial, participants...

Current scientific evidence does not support the implementation of genetic tests to enhance processes talent identification and development systems. Regardless this consensus, it appears likely that sport stakeholders will continue using tests. This paper aimed provide practitioners with some best practice guidelines if implementing testing within their organisations. First, we assess growth perceived flaws direct-to-consumer companies targeted towards sport. The sports genomic literature is...

Physiological performance may be limited by reduced systemic glucose availability to working muscles. Continuous monitors (CGM) measure interstitial every 1-15 minutes, offering a practical way assess during sporting activity. However, empirical research has predominantly focused on endurance-based sports, whereas responses professional competitive football matches remain unknown. This study evaluated the feasibility and utility of CGM in football. Eight professional, male outfield...

Objectives To report the incidence and burden of concussion in elite English football; to compare between sexes (men’s vs women’s football), activity (matches training) level (international domestic). Methods Concussion injuries men’s international football (2012–2022) (2013–2022) (2018–2022) domestic were diagnosed recorded by club/team-based medical practitioners, alongside training match exposure. Severity was also reported based on days lost due concussion; subsequently, calculated....

Asymmetrical athletes produce movements where the external load is unequally distributed in lower extremities e.g., cricket fast bowling. Loading magnitude known to affect bone adaptation. It not understood if tibial characteristics differ between legs when they are exposed different magnitudes of load, as happens asymmetrical athletes. This study aimed assess association and compare effect that loading has Footballers were recruited a comparator group. Inertial measurement units (IMU)...

The aim of the study was to assess relationships between match activity variables, subsequent fatigue and neuromuscular performance capacity in elite soccer players. Subjects (n = 10) were professional players participating English Championships. Match variables markers status measured before following two matches. Creatine kinase (CK) muscle soreness at baseline, immediately following, as well 40 64 h post-match. Countermovement jump perceived ratings wellness then Relationships shown CK...

Psychological characteristics influence the performance of youth football players and are significant predictors development success at adulthood. Although genetic factors may explain a considerable portion inter-individual differences in psychological traits, psychogenetic research is scarce. As such, purpose this study was to examine association ten single nucleotide polymorphisms (SNPs) with personality mental toughness profiles academy players. Seventy-three male under-12 under-18 from...

Football match-play causes muscle damage and provokes an inflammatory response. Rapid recovery is paramount to optimising subsequent performance reducing injury risk. Turmeric contains high concentrations of curcumin, a polyphenol that has been shown reduce soreness post-exercise in recreational exercisers. However, it unknown whether curcumin-containing supplement can support elite footballers between matches. This applied study explored turmeric could improve performance, subjective...

The purpose of the study was to investigate current use genetic testing in UK elite sport and assess how might be received by those employed sport. Seventy-two athletes 95 support staff at sports clubs governing bodies completed an online survey 11 questions concerning their experience beliefs regarding Genetic related performance injury susceptibility is conducted sport, albeit a relatively small proportion (≤17%) (≤8%). Athletes agree that genetics are important determining status (≥79%)...
