The development of Global Positioning System (GPS) technology has contributed in various ways to improving the physical condition of modern football players by enabling the quantification of physical load. Previous studies have reported that the running demands of matches vary depending on playing position and formation. Over the past decade, despite the widespread use of GPS technology, studies that have investigated the running performance of young football players within the 1-4-3-3 formation are particularly limited. Therefore, the aim of the present study was to create the match running profile of playing positions in the 1-4-3-3 formation among high-level youth football players. An additional objective of the study was to compare the running performance of players between the two halves of a match. This study involved 25 football players (Under-19, U19) from the academy of a professional football club. Data were collected from 18 league matches in which the team used the 1-4-3-3 formation. Positions were categorized as Central Defenders (CDs), Side Defenders (SDs), Central Midfielders (CMs), Side Midfielders (SMs), and Forwards (Fs). The players’ movement patterns were monitored using GPS devices and categorized into six speed zones: Zone 1 (0.1–6 km/h), Zone 2 (6.1–12 km/h), Zone 3 (12.1–18 km/h), Zone 4 (18.1–21 km/h), Zone 5 (21.1–24 km/h), and Zone 6 (above 24.1 km/h). The results showed that midfielders covered the greatest total distance (p = 0.001), while SDs covered the most meters at high and maximal speeds (Zones 5 and 6) (p = 0.001). In contrast, CDs covered the least distance at high speeds (p = 0.001), which is attributed to the specific tactical role of their position. A comparison of the two halves revealed a progressive decrease in the distance covered by the players at high speed: distance in Zone 3 decreased from 1139 m to 944 m (p = 0.001), Zone 4 from 251 m to 193 m (p = 0.001), Zone 5 from 144 m to 110 m (p = 0.001), and maximal sprinting (Zone 6) dropped from 104 m to 78 m (p = 0.01). Despite this reduction, the total distance remained relatively stable (first half: 5237 m; second half: 5046 m, p = 0.16), indicating a consistent overall workload but a reduced number of high-speed efforts in the latter stages. The results clearly show that the tactical role of each playing position in the 1-4-3-3 formation, as well as the area of the pitch in which each position operates, significantly affects the running performance profile. This information should be utilized by fitness coaches to tailor physical loads based on playing position. More specifically, players who cover greater distances at high speeds during matches should be prepared for this scenario within the microcycle by performing similar distances during training. It can also be used for better preparing younger players (U17) before transitioning to the U19 level. Knowing the running profile of the next age category, the fitness coach can prepare the players so that by the end of the season, they are approaching the running performance levels of the next group, with the goal of ensuring a smoother transition. Finally, regarding the two halves of the game, it is evident that fitness coaches should train players during the microcycle to maintain high movement intensities even under fatigue. Full article

This study aimed to describe the training leading to the Zwift Academy (ZA) Finals of a world-class road cyclist who earned a professional contract after winning the contest. Four years of daily power meter data were analyzed (male, 25 years old, 68 kg, VO₂max: 85 mL·min⁻¹·kg⁻¹, and 20-min power: 6.37 W·kg⁻¹), focusing on load, volume, intensity, and strategies. Early training alternated between long, moderate-intensity sessions and shorter high-intensity sessions, with easy days in between. Gradually, the structure was progressively modified by increasing the duration of moderate-intensity (MIT) and high-intensity (HIT) and, subsequently, moving them to “high-volume days”, creating a sort of “all-in days” with low-intensity (LIT), MIT, and HIT. Moderate use of indoor training and a few double low-volume, low-intensity sessions were noted. These data provide a deep view of a 4-year preparation period of ZA, providing suggestions for talent identification and training, thereby highlighting the importance of gradual progression in MIT and HIT.

The built environment plays a critical role in achieving climate neutrality, yet the construction sector continues to contribute significantly to carbon emissions and resource depletion. This study evaluates the experimental phase of the New European Bauhaus Academy (NEBA) Alliance pilot project, which aims to support sustainable transformation in the built environment through the integration of circular economy principles, adaptive reuse, and nature-based solutions. Conducted at the Lodz University of Technology, the pilot study involved interdisciplinary modules combining Building Information Modeling (BIM), urban regeneration strategies, and sustainable material use. A mixed-methods approach was employed, including structured surveys and qualitative analysis of student projects, to assess the effectiveness of these interventions. The results indicate that the pilot project successfully enhanced the participants’ understanding of sustainable design practices and their application in real-world architectural and urban contexts. Participants demonstrated increased competence in using digital tools for low-carbon design and in proposing regenerative solutions for existing urban fabric. The findings suggest that targeted, design-led initiatives can contribute meaningfully to the transformation of the built environment, aligning with the goals of the European Green Deal and the New European Bauhaus. This study offers a replicable model for embedding sustainability into professional practice through applied, context-sensitive strategies. Full article

Over the past 20 years, the use of the global positioning system (GPS) in football has become widespread. This technology has facilitated the tracking of external load both during training sessions and matches. Creating an external load profile for each playing position within specific formations can assist the coaching staff in shaping the training load of the microcycle according to the demands of each position. The purpose of this study was to create the running performance profile for high-level young football players based on their playing position in the 1-4-2-3-1 formation and to investigate potential differences between positions. Additionally, the study aimed to compare the players’ running performance across the two halves of the match. The study involved 22 Under-19 players from the academy of a professional football team. Only matches where the team used the 1-4-2-3-1 formation were analyzed (10 matches). The playing positions were categorized as: Central Defensive Fielders (CDFs), Central Midfielders (CMFs), Forwards (FWDs), Wide Defensive Fielders (WDFs), and Wide Midfielders (WMFs). Player movement was tracked using GPS devices and categorized into four velocity zones: (Zone 1: 3.6–10.8 km/h, Zone 2: 10.9–18.0 km/h, Zone 3: 18.1–25.2 km/h, Zone 4: >25.2 km/h). Depending on whether normality was present in our data, either a one-way analysis of variance (ANOVA) or a Kruskal–Wallis test was conducted. A subsequent analysis was performed to compare the performance between the first and second halves of the match, using either the independent samples t-test or the Mann–Whitney U test. The results showed that CMF players covered the greatest total distance and had the highest movement velocity (distance/min) compared to all other positions (p = 0.001). In high-speed running (>18 km/h), CMF again covered the greatest distance, followed by WDF. In sprinting, CDF covered the shortest distance and reached the lowest maximum speed (p = 0.001). CMF performed the most accelerations and decelerations across all positions (p = 0.001). As for the entire team, total distance, movement rate, and the number of accelerations and decelerations decreased in the second half. All players except the WDF also showed a decrease in total distance, while midfielders experienced a notable drop in sprint distance. In conclusion, this study underscores the positional specificity of physical demands in elite football and the systematic decline in physical output as matches progress. While all positions demonstrated some level of second-half performance deterioration, midfielders experienced the most significant decreases in both volume and intensity-related metrics. These insights offer valuable implications for position-specific physical condition, recovery planning, and substitution strategies, helping to optimize performance and manage player load in elite football environments. It should be reiterated that the results of the present study apply exclusively to the 1-4-2-3-1 formation. Full article

Professional training in elite team handball academies is key to developing top players, yet its direct impact on physical performance remains unclear. This study aimed to (1) provide professional training to elite adolescent players and (2) assess performance improvements using a team handball-specific test. Thirty elite male players (six goalkeepers, 24 field players) participated in an 11-week program, with nine under-19 (17.2 ± 1.3 years) and nine under-17 (15.6 ± 0.9 years) field players completing at least 80% of sessions. All underwent pre- and post-testing using the game-based performance test. A two-way ANOVA analyzed differences between tests and age groups as well as playing positions. Significant improvements (p < 0.05) were found in defense and offense time and body weight for both groups. Under-17 players also showed a significant increase in peak oxygen uptake (+9%), ball velocity (+7%), and jump height (+20%). Agility in defense and offense improved in under-19 (+3%) and under-17 (+6%) players, aligning with training goals. Positional differences were observed between backcourt players and wings (p < 0.01) in the ball velocity, while all players showed improvements in both defense and offense performance. We suggest that professional and targeted specific training at this age has a significant impact on the long-term development of adolescent team handball players and is the basis for a professional handball career.

Commonalities between linguistically and culturally sensitive pedagogy (LCRP) and education for sustainable futures (ESF) suggest the benefits of connecting these transdisciplinary themes in teacher education. This paper reports on a qualitative study of how educators made sense of connections between LCRP and ESF as part of a European teacher education project, using secondary analysis of project evaluation data. The context for the study is the Erasmus + Teacher Academy Project ‘Teaching Sustainability’ (TAP-TS) (2022–2025), which aimed to develop the sustainability competences of student teachers, teachers, and teacher educators through the co-design of learning and teaching resources during online, hybrid, and face-to-face events as part of an international community of practice. Activities linking LCRP and ESF were presented and evaluated in four discrete teacher education courses, as part of TAP-TS. The study found that connections between LCRP and ESF were meaningful for educators but that this differed between individuals related to their personal and professional experience. The transdisciplinary and international nature of TAP-TS provided learning opportunities, but significant changes are likely to require sustained support for teachers in schools and as part of school communities.

This study aims to analyze online job postings using machine learning-based, semantic approaches and to identify the expertise roles and competencies required for big data professions. The methodology of this study employs latent Dirichlet allocation (LDA), a probabilistic topic modeling technique, to reveal hidden semantic structures within a corpus of big data job postings. As a result of our analysis, we have identified seven expertise roles, six proficiency areas, and 32 competencies (knowledge, skills, and abilities) necessary for big data professions. These positions include “developer”, “engineer”, “architect”, “analyst”, “manager”, “administrator”, and “consultant”. The six essential proficiency areas for big data are “big data knowledge”, “developer skills”, “big data analytics”, “cloud services”, “soft skills”, and “technical background”. Furthermore, the top five skills emerged as “big data processing”, “big data tools”, “communication skills”, “remote development”, and “big data architecture”. The findings of our study indicated that the competencies required for big data careers cover a broad spectrum, including technical, analytical, developer, and soft skills. Our findings provide a competency map for big data professions, detailing the roles and skills required. It is anticipated that the findings will assist big data professionals in assessing and enhancing their competencies, businesses in meeting their big data labor force needs, and academies in customizing their big data training programs to meet industry requirements.

Background: Early-maturing players tend to have physical advantages during formative stages, but it remains unclear whether these advantages translate into long-term professional success. This study examines how biological maturation influences participation and career trajectories in youth football. Methods: Anthropometric and competitive data were collected from 47 players (13.53 ± 1.08 years) in a top-tier academy during the 2010–2011 season. The maturation status was assessed using the Tanner–Whitehouse II RUS method, and the career outcomes were tracked in 2024–2025. Results: Early-maturing players showed higher anthropometric values and greater participation. However, late maturers were more likely to reach professional football (p = 0.003), with all players competing in the top five European leagues belonging to the late-maturing group. Conclusions: Early maturation does not guarantee professional success. Strategies such as bio-banding and personalized training can reduce biases and support talent development, highlighting the need for a more holistic approach to player evaluation. Full article

The running performance of football players is influenced by their team’s formation as well as by their playing position. The creation of the external load profile provides information to the coaching staff for personalized loading of the players based on their playing positions. The aim of this study was to create the athletic running profile of high-level football players under 17 years of age (U17) in the 1-4-3-3 formation, and to investigate the differences between the playing positions in the formation. The study involved 20 football players from a football academy of a professional team. For the study, 13 league matches were used in which the team played with the 1-4-3-3 formation. Positions were classified as central defenders (CDs), side defenders (SDs), central midfielders (CMs), side midfielders (SMs), and forwards (Fs). The players’ movement patterns were captured using a GPS device and categorized into six velocity zones (first: 0.1–7.19 km/h, second: 7.2–10.99, third: 11–14.39 km/h, fourth: 14.4–19.79 km/h, fifth: 19.8–25.19 km/h, sixth: >25.2 km/h). The accelerations and decelerations recorded were those exceeding 2 m/s⁻¹. The level of statistical significance was set at p < 0.05. The results showed that CMs exhibited the greatest external load in total distance and in specific distances in the other velocity zones (p < 0.05). Forwards dominated high-intensity efforts, leading in Distance Zone 5 with SD (mean = 555 m and mean = 559 m, respectively), as well as in Distance Zone 6 (F: mean = 146 m) and in high-speed running values (mean = 701 m). Side players, particularly SD and SM, contributed dynamically through elevated high-speed running (p < 0.05) and maximum speed (p < 0.05), reflecting their role in both transitions and positional phases of play. The study’s results clearly show that the physical demands of the playing positions in the 1-4-3-3 formation differ. This difference is likely due to the different tactical roles of each playing position. This variation between playing positions emphasizes the need for individualized loading of players during the training microcycle. Full article

Background: A rapid intervention team is a broad category of special teams used by police and emergency respondents to cover various needs. It is essential to ensure the safety and well-being of people in emergencies, minimising the risk of harm and maximising the chances of survival. Objective: This study aimed (i) to identify the fitness profiles and levels of POs from the EIR of the Lisbon Metropolitan Command (COMETLIS, PSP, Portugal), considering age classes; (ii) to directly compare the observed fitness profiles to previous research and normative data; and (iii) to compare the fitness profile of POs from the EIR with cadets from the Police Academy. Methods: This cross-sectional observational study included the participation of 121 male POs from the EIR of the Lisbon Metropolitan Command (Portugal) and 92 male cadets from the Police Academy (Lisbon, Portugal). The assessment protocol sequence involved the collection of biosocial data (age classes: ≤29 years; 30–39 years; 40–49 years), a body size assessment, and a fitness assessment (horizontal jump, handgrip strength, 60 s sit-ups and 20 m shuttle run). Results: (i) In the ≤29 years age class, POs performed better in all fitness tests (highlighting that the age class had a statistically significant effect on performance in the horizontal jump, sit-ups, 20 m shuttle run, and predicted VO₂max), and they showed significantly better performance than cadets in handgrip (left, right, and sum), and significantly worse performance in sit-ups and predicted VO₂max. (ii) In the 30–39 years age class, POs had significantly worse performance than cadets in the horizontal jump, sit-ups, 20 m shuttle run, and predicted VO₂max, even after controlling for age. Conclusions: (i) The fitness performance decreased as the age class became older; (ii) the handgrip strength and cardiovascular capacity attributes were between the standard and excellent levels according to the ACSM guidelines for the general population; (iii) POs from the EIR were stronger than cadets in terms of handgrip strength but weaker in terms of lower limb power, abdominal muscular endurance, and aerobic capacity; and (iv) the differences observed between POs from the EIR and cadets in the 30–39 years age class emphasise the importance of physical training after the training period and throughout professional life.

Background: Orthodontic appliances increase biofilm accumulation by expanding plaque retention sites. Enamel demineralization and periodontal inflammation are considered to be the most prevalent consequences of biofilm formation in orthodontic patients, with reported prevalence rates of up to 50%. To date, there are different procedures and indications that have been used for the treatment of these conditions. Therefore, professionals may use different technologies and protocols to control bacterial biofilm. The aim of this study was to investigate the protocols and technologies used by Italian dental professionals to maintain good oral health in orthodontic patients before, during and after treatment. Methods: A total of 155 dental professionals, dentists, dental hygienist students and dental hygienists, attending the Italian Academy of Advanced Technologies in Oral Hygiene Sciences (A.T.A.S.I.O.) congress, completed a questionnaire to identify prevention technologies and protocols before, during and after orthodontic treatment. Results: The results show equivalent responses between dentists and dental hygienists, with most dental hygienists more likely to personalize treatment. Remineralization technologies and protocols are selected based on patient characteristics. During professional oral hygiene sessions, the most commonly used technologies before, during and after therapy are ultrasonic scaler and airflow with powders. Mouthwashes and toothpastes are customized and shared with the patient, with remineralizing technologies predominant in toothpastes. After treatment, aesthetics is evaluated and the whitening protocol is selected based on the patient’s characteristics. Conclusions: There is not a specific prevention program associated with each orthodontic therapy in the literature, so it is necessary to tailor the treatment to best manage the risks of orthodontic therapy and maintain healthy tissues.

Currently, the administration of innovation and technology, and the execution of technological projects (in this case, mechatronic projects) is, for all types of organizations, a challenge that requires the use of the creativity and initiative of its professionals, investing or implementing processes, machines, products, and services in such a way that inventions, designs, and prototypes provide solutions to environmental problems and facilitate society. Therefore, in innovation projects, it should be considered that it corresponds not only to the application of new technologies, but also to the generation of an outcome that is useful for the objective, quantifiable, and productive segment, as applied to mechatronic projects. Therefore, it is necessary and relevant to carry out a process of orderly development in the following phases: identification of need, ideation, development, construction, and verification of the final solution of these mechatronic projects. The above is turned towards a comprehensive design process around the academy, which for the purposes of this research takes place at the Universidad Autónoma del Caribe, which, according to the indicators of technological development and innovation, is positioned among the top ten positions at a national level (over 350 measured universities) in the DTI-Sapiens ranking, published every two years since 2017 by the consulting firm Sapiens Research and recognized by the international IREG Observatory. The Unit Department for the Administration and Execution of Technological Projects and Innovation: A Case Applied to Mechatronic Projects aims to achieve a balanced technological offer in the universe of R&D&I projects in mechatronics, among economic and social scientific values. In this way, it will be possible to consolidate links with the socioeconomic environment for the transfer of existing knowledge in HEIs, its exploitation by stakeholders, and the increase in the development of R&D&I projects, strengthening capacities in the UEES relationship for the transfer of know-how to companies.

Many education systems adopt neoliberal privatisation and marketisation approaches to diversify education provision and improve quality. England is a leading example, transforming local authority-maintained schools into academies. In contrast, Finland resists neoliberalism and maintains a small number of independent schools. This paper examines how resources and leadership are distributed in academies and independent schools to explain the different educational paths taken by England and Finland. This study uses a scoping review approach to explore and contrast academies and independent schools. The comparison covers aspects such as history, education administration, local governance, accountability, curriculum and performance, teacher professional development and home–school–community relationships. The findings reveal that academies in England often concentrate leadership roles and resources among a privileged few, including large Multi-Academy Trusts, technocratic trustees and curriculum experts. This concentration tends to marginalise local communities and parents, particularly those from disadvantaged backgrounds. In Finland, independent schools serve a supplementary role within the education system, catering to specific cultural, linguistic and religious groups while adhering to the national core curriculum and regulations. While existing studies critique the academisation movement in England and commend the high-performing public school system in Finland, a direct comparison between academies in England and independent schools in Finland has been lacking. This systematic review offers original insights into these two types of schools and clarifies why neoliberal approaches often exacerbate rather than mitigate disparities in education access and equity.

The recognition of high-speed demands in football has led elite academies to prioritize acceleration capabilities for player selection and promotion, particularly given their fundamental role in the motor skills of professional players and their impact on goal-related opportunities. This study explored the effectiveness of game-based versus resisted sprint training methods in enhancing the acceleration abilities of professional women’s football players. Over the entire competitive period, the training load of 26 athletes (24.2 ± 3.7 years) was assessed using GPS devices, and sprint capabilities were evaluated through four 30-m acceleration tests spaced six weeks apart. Linear mixed models (LMMs) analyzed physical load parameters, including distance covered at high speeds, speed events, and maximum speed, with periods and players as fixed and random effects, respectively. Significant sprint performance improvements were observed across all intervals, particularly when high-intensity distance volumes were combined with resisted sprint training. Conversely, high-intensity running without additional stimuli also led to performance gains, albeit to a lesser extent. Both game-based and resisted sprint training methods were effective in enhancing acceleration capabilities, while the absence of specific sprint focus did not significantly alter sprint performance. These findings support the inclusion of tailored sprint training in athletic programs to optimize acceleration in women’s football players. Full article

This study examines the integration of disaster risk reduction (DRR) into security and defense studies curricula at Serbian universities, focusing on public and private institutions. As climate change accelerates and natural disasters become more frequent, addressing these risks is critical for national security and sustainable development. This research evaluates the extent of DRR incorporation in curricula and the use of emerging technologies in DRR education. A qualitative analysis of programs at institutions such as the Faculty of Security Studies at the University of Belgrade, the Military Academy, the University of Criminal Investigation and Police Studies, and private universities like Singidunum and Educons University reveals that public institutions have made significant progress. However, private universities still need comprehensive DRR-focused courses and technological integration. This study recommends fostering collaboration between public and private universities, expanding access to the National Simulation Center, and incorporating modern technologies and active learning strategies across curricula to bridge existing gaps. These steps equip future security professionals with the practical skills and interdisciplinary knowledge necessary for effective disaster management in an increasingly complex risk environment.
