There is growing concern that exposure to head acceleration events (HAEs) may be associated with long-term neurological effects. To quantify the incidence and probability of HAEs during men's professional rugby league match-play on a group and individual basis using instrumented mouthguards (iMGs). A total of 91 men's professional rugby league players participating in the 2023 Super League season wore iMGs, resulting in the collection of 775 player matches (mean 8.3 matches per player). Incidence of HAEs (rate of HAEs per median playing time) was calculated via generalised linear mixed models. Probability of HAEs (likelihood of experiencing an HAE during a tackle-event) was calculated using an ordinal mixed effects regression model. The meanincidence of HAEs exceeding 25g per median playing time ranged from 0.86-1.88 for backpositions and 1.83-2.02 for forwardpositions. The probability of exceeding 25g during a tackle event was higher for ball-carriers (6.29%, 95% confidence intervals [CI] 5.27-7.58) than tacklers (4.26%, 95% CI 3.48-5.26). Several players exhibited considerably higher incidence and probability than others, e.g. one player averaged 5.02 HAEs exceeding 25g per median playing time and another had a probability of 20.00% of exceeding 25g during a tackle event as a ball-carrier and 34.78% as a tackler. This study quantifies the incidence and probability of HAEs in men's rugby league match-play, advancing our understanding of HAE exposure in men's rugby league. These findings support the development of individualised HAE mitigation strategies targeted at individuals with elevated HAE exposures.

A novel, yet simple, airborne microplastic (MP) sampling approach using global pollen monitoring equipment was applied to identify, characterise and quantify outdoor airborne MPs for the first time. Modification of Burkard spore trap tape adhesive provided particle capture and facilitated downstream spectroscopy analysis. 36 polymer types were identified from a total of 21 days sampling using Burkard spore traps at two locations (United Kingdom and South Africa). MPs were detected in 95 % of daily samples. Mean MP particle levels were 2.0 ± 0.9 MP m-3 (11 polymer types) in Hull (U.K.), during March, 2.9 ± 2.0 MP m-3 (16 types) in Hull in July, and 11.0 ± 5.7 MP m-3 (29 types) in Gqeberha, (S.A.) in August 2023. The most abundant polymer type was nylon (Gqeberha). The approach was compared with two passive sampling methods whereby 27 polymer types were identified and of these, 6 types were above the limit of quantification (LOQ), with poly(methacrolein:styrene) (PMA/PS) the most abundant. Irregularly shaped MPs < 100 µm in length were predominant from all sampling approaches. For the first time, airborne MPs were chemically characterised and quantified using volumetric pollen sampling equipment, representing a viable approach for future airborne MP monitoring.

The importance of infaunal bioturbators for the functioning of marine ecosystems cannot be overstated. Inhabitants of estuarine and coastal habitats are expected to show resilience to fluctuations in seawater temperature and pH, which adds complexity to our understanding of the effects of global change drivers. Further, stress responses may be propagated through chemical cues within and across species, which may amplify the costs of life and alter species interactions. Research into the molecular mechanisms underlying this resilience has been limited by a lack of annotated genomes and associated molecular tools. In this study, we present the first chromosome-level, annotated draft genome of the marine ragworm Hediste diversicolor, specifically mapping genes important for chemical communication, sensing and pH homeostasis. Using these resources, we then evaluate the transcriptomic and behavioural responses of two distinct populations - one field-sampled from Portugal (Ria Formosa) and one laboratory-acclimated and -bred from the United Kingdom (Humber) - to changes in seawater pH, temperature, and odour cues from a low pH-stressed predator. Both populations displayed adaptive responses to future oceanic conditions, with targeted acid-base regulation in the Ria Formosa population experiment, and broader changes in metabolism and growth genes in the Humber population experiment. Chemical cues from stressed fish predators induced genes related to Schreckstoff biosynthesis in ragworms. Additionally, under future ocean conditions including increased temperature, the Humber population exhibited signs of cellular stress and damage. Our findings using the new annotated genome offer novel insights into the molecular arsenal of acid-base regulation which aids in predicting the impacts of an increasingly acidified and unstable ocean, and to transfer this knowledge to investigate these mechanisms in species with less tolerance.

This comparative study delves into the intricate regulatory compliance mechanisms governing data privacy in Nigeria and the United States. Employing a qualitative methodology, this research synthesizes existing literature and case studies to highlight the pivotal role of data protection regulations in safeguarding personal information in an increasingly digital world. The analysis begins with an exploration of the conceptual framework of data privacy, emphasizing key principles such as transparency, accountability, and data minimization. It then meticulously examines the Nigerian Data Protection Regulation (NDPR) and the diverse U.S. legal landscape, including the California Consumer Privacy Act (CCPA) and the Health Insurance Portability and Accountability Act (HIPAA). The main findings reveal significant differences in regulatory approaches, with Nigeria's centralized enforcement by the National Information Technology Development Agency (NITDA) contrasting sharply with the U.S.'s fragmented state and federal oversight. Case studies underscore the challenges faced by both jurisdictions in ensuring compliance, ranging from resource constraints in Nigeria to the complexities of navigating multiple regulatory requirements in the U.S. The study concludes that while both countries emphasize the importance of data privacy, their divergent legal landscapes reflect unique cultural, economic, and operational contexts. The research recommends harmonizing data protection standards, enhancing enforcement mechanisms, and fostering greater public awareness to address the evolving challenges of data privacy. This study contributes to the global discourse on data privacy by offering insights into the strengths and weaknesses of different regulatory frameworks, thereby providing a roadmap for policymakers, businesses, and other stakeholders to navigate the complexities of data privacy compliance.

ABSTRACT The individual response to load is multifactorial and complicated by transient temporal changes in biological maturation. The period surrounding peak height velocity exposes potentially “fragile” individuals to systematic, age-related increases in training loads. Bio-banding allows practitioners to manage the biological diversity and align training to the individual development needs . This study explores the acute impact of maturation on neuromuscular performance and perceived intensity through comparing both chronological and bio-banded training sessions. 55 male soccer players (mean ± SD; age 13.8 ± 1.4 years) were recruited from an EPPP academy. Following a warm-up and standardised sub-maximal run (30–15IFT), players competed in five bouts of 5-min 6v6 small-sided games (SSGs) before repeating the standardised sub-maximal run. The sessions were repeated on three occasions with chronological SSGs and the same with bio-banded SSGs wearing foot-mounted inertial measurement units (PlayerMakerTM) with differential ratings of perceived exertion used to quantify internal loads. Mixed linear modelling indicated maturity-specific pre–post differences in neuromuscular response, stride length and cadence having contrasting responses pre- (reduced) and post-PHV (increased), and larger changes in post sessions stiffness for pre- (∼18.6 kN·m−1) and circa-PHV (∼12.1 kN·m− 1) players. Secondly, there were small to large differences in neuromuscular response (RSI, stride length, stiffness, and contact time) and perceptions of intensity between conditions, with bio-banding generally reducing pre–post changes. Bio-banding may therefore offer a mechanism to prescribe maturity-specific training loads which may help to alleviate the impact of repeated exposure to high-intensity activity, thus reducing injury risk whilst promoting long-term player development. Highlights Utilising a sub-maximal running protocol (30–15IFT) with foot mounted accelerometers can detect maturity specific responses to football specific training activity, which aligns with subjective perceptions of intensity. Chronologically derived small-sided games elicit different acute responses between players of varying maturity status, which is somewhat negated when bio-banded small-sided games are used instead. Bio-banding training sessions may offer practitioners a practical way of managing maturity-specific trainings load to reduce injury risk and promote long-term players development.

The aims of the current study were to investigate the use of dRPE with academy soccer players to: 1) examine the effect of bio-banded and non-bio-banded maturity groups within SSG on players dRPE; 2) describe the multivariate relationships between dRPE measures investigating the sources of intra and inter-individual variation, and the effects of maturation and bio-banding. Using 32 highly trained under (U) 12 to U14 soccer players (mean (SD) age 12.9 (0.9) years, body mass 46.4 (8.5) kg and stature 158.2 (14.9) cm) academy soccer players from two English professional male soccer academies. Players were categorised according to somatic maturity status using estimated percentage of adult stature attainment, with players randomly assigned into teams to play 4v4 SSG. The study used a repeated measures design, whereby the selected players participated within 6 bio-banded (maturity matched [pre-PHV Vs pre-PHV and post-PHV vs post PHV] and miss-matched [pre-PHV vs post-PHV] and 6 mixed maturity SSG at their respective clubs. Using mixed and fixed effect regression models, it was established hat pre-PHV players exhibited higher dRPE compared with their post-PHV counterparts. Mixed bio-banded games reported higher dRPE outputs overall. Variation in dRPE measures across a series of bio-banded games are caused by both between and within sources of variation in relatively equal amounts. Across a series of bio-banded games, the four dRPE measures do not provide unique information, and between variation is best expressed by one or two highly correlated components, with within variation best explained by a single equally loaded component. Using a bio-banding SSG design study, we have shown that pre-PHV players report higher subjective measures of exertion than post-PHV players during. Additionally, when evenly mixing players based on measures of maturation, higher measures of perceived exertion were generally reported.

A small evidence base supports the use of virtual reality in professional soccer, yet there is a lack of information available on perceptions and desire to use the technology from those employed at professional soccer clubs. Therefore, the aim of the study was to compare and quantify the perceptions of virtual reality use in soccer, and to model behavioural intentions to use this technology. This study surveyed the perceptions of coaches, support staff, and players in relation to their knowledge, expectations, influences and barriers of using virtual reality via an internet-based questionnaire. To model behavioural intention, modified questions and constructs from the Unified Theory of Acceptance and Use of Technology were used, and the model was analysed through partial least squares structural equation modelling. Respondents represented coaches and support staff (n = 134) and players (n = 64). All respondents generally agreed that virtual reality should be used to improve tactical awareness and cognition, with its use primarily in performance analysis and rehabilitation settings. Generally, coaches and support staff agreed that monetary cost, coach buy-in and limited evidence base were barriers towards its use. In a sub-sample of coaches and support staff without access to virtual reality (n = 123), performance expectancy was the strongest construct in explaining behavioural intention to use virtual reality, followed by facilitating conditions (i.e., barriers) construct which had a negative association with behavioural intention. Virtual reality has the potential to be a valuable technology within professional soccer although several barriers exist that may prevent its widespread use.

The primary aims of this study were to examine the effects of bio-banding players on passing networks created during 4v4 small-sided games (SSGs), while also examining the interaction of pitch size using passing network analysis compared to a coach-based scoring system of player performance. Using a repeated measures design, 32 players from two English Championship soccer clubs contested mixed maturity and bio-banded SSGs. Each week, a different pitch size was used: Week 1) small (36.1 m2 per player); week 2) medium (72.0 m2 per player); week 3) large (108.8 m2 per player); and week 4) expansive (144.50 m2 per player). All players contested 12 maturity (mis)matched and 12 mixed maturity SSGs. Technical-tactical outcome measures were collected automatically using a foot-mounted device containing an inertial measurement unit (IMU) and the Game Technical Scoring Chart (GTSC) was used to subjectively quantify the technical performance of players. Passing data collected from the IMUs were used to construct passing networks. Mixed effect models were used with statistical inferences made using generalized likelihood ratio tests, accompanied by Cohen's local f2 to quantify the effect magnitude of each independent variable (game type, pitch size and maturation). Consistent trends were identified with mean values for all passing network and coach-based scoring metrics indicating better performance and more effective collective behaviours for early compared with late maturation players. Network metrics established differences (f2 = 0.00 to 0.05) primarily for early maturation players indicating that they became more integral to passing and team dynamics when playing in a mixed-maturation team. However, coach-based scoring was unable to identify differences across bio-banding game types (f2 = 0.00 to 0.02). Pitch size had the largest effect on metrics captured at the team level (f2 = 0.24 to 0.27) with smaller pitch areas leading to increased technical actions. The results of this study suggest that the use of passing networks may provide additional insight into the effects of interventions such as bio-banding and that the number of early-maturing players should be considered when using mixed-maturity playing formats to help to minimize late-maturing players over-relying on their early-maturing counterparts during match-play.
