Football clubs regularly test and monitor players, with different approaches reflecting player age and competitive level. This narrative review aims to summarise justifications for testing and commonly used testing protocols. We also aim to discuss the validity and reliability of specific tests used to assess football players and provide a holistic overview of protocols currently used in football or those demonstrating potential utility. The PubMed, SportDiscus, and Google Scholar databases were screened for relevant articles from inception to September 2024. Articles that met our inclusion criteria documented tests for several purposes, including talent identification or the assessment of growth/maturation, physiological capacity, sport-specific skill, health status, monitoring fatigue/recovery, training adaptation, and injury risk factors. We provide information on specific tests of anthropometry, physical capacity, biochemical markers, psychological indices, injury risk screening, sport-specific skills, and genetic profile and highlight where certain tests may require further evidence to support their use. The available evidence suggests that test selection and implementation are influenced by financial resources, coach perceptions, and playing schedules. The ability to conduct field-based testing at low cost and to test multiple players simultaneously appear to be key drivers of test development and implementation among practitioners working in elite football environments.

(1) Background: The literature has demonstrated several pathways that link obesity with stress. Thus, new approaches to weight management programs must also integrate health coaching and telemonitoring for overall health and wellbeing. This study aimed to measure stress, anxiety, and depression scales (DASS-21) in overweight and obese participants who joined a pilot randomized controlled trial (RCT) and the association between changes in DASS-21 scores and changes in anthropometric measures. (2) Methods: Fifty participants were enrolled in a randomized controlled trial and divided into two groups: the intervention group, which received a hypocaloric diet remotely, weekly telemonitoring, and monthly telehealth coaching, and the control group, which only followed a hypocaloric diet without any support. The Arabic version of the Depression Anxiety Stress Scales (DASS-21) was used. (3) Results: The data reveal that participants from the intervention group exhibited a significant decrease in the anxiety scale after 3 months compared with the control group. In addition, the correlations between depression, anxiety, stress, and all anthropometric measures in the intervention group showed a moderately significant positive correlation between changes in waist circumference and depression. (4) Conclusions: The findings confirm that integrating health coaching and telemonitoring can improve wellbeing and weight loss. Full article

We developed an innovative system that combines Natural Language Understanding (NLU), a curated knowledge base, and the efficient management of a Large Language Model (LLM) to support motivational health coaching. Using Rasa as the core framework, we enhanced it by integrating the GPT-3.5-turbo model. Users opt into reflective dialogues during conversations. When they respond to open-ended questions, their input goes directly to the GPT-3.5-turbo model, allowing for more flexible responses. To provide curated trustworthy content, we integrated a knowledge provision component that searches a PDF-based knowledge base and generates user-friendly responses using Retrieval-Augmented Generation. We tested the system in a real-world scenario by deploying it on a Nao robot in seven older adults’ homes for 1–2 weeks, encouraging positive behavioral changes in some users. Our system serves as a valuable foundation for building an even more integrated, personalized system that can connect with other Application Programing Interfaces (APIs) and integrate with home sensors and edge devices.

Background: Despite the well-documented benefits of exercise and sports participation, young athletes are particularly vulnerable to musculoskeletal injuries. This is especially true during periods of rapid growth, sports specialisation, and high training loads. While injuries are an inevitable aspect of sports participation, the risk can be minimised by promoting the development of strong, resilient tissues through proper nutrition and injury prevention strategies. Moreover, targeted nutrition strategies can accelerate recovery and rehabilitation, allowing for a quicker return to sports participation. Methods: This narrative review synthesises scientific evidence with practical insights to offer comprehensive dietary recommendations aimed at strengthening tissues and supporting the healing process during recovery and rehabilitation. The selection of all sources cited and synthesised in this narrative review were agreed upon by contributing author consensus, experts in sports nutrition (R.A., H.V., B.D.) and exercise and sports medicine (M.H.). Results: Key topics include factors that contribute to injury susceptibility, general dietary recommendations for growth and development, sports nutrition guidelines, and nutrition considerations during injury and rehabilitation. This review also addresses external factors that may lead to suboptimal nutrition, such as food literacy and eating disorders. Conclusions: By highlighting these factors, this article aims to equip coaches, nutritionists, dietitians, athletic trainers, physical therapists, parents/guardians, sporting organisations, and schools with essential knowledge to implement effective nutritional strategies for injury prevention, recovery, and rehabilitation, ultimately enhancing long-term health and athletic performance.

The COVID-19 pandemic has underscored the urgency of understanding virus transmission dynamics, particularly in indoor environments characterized by high occupancy and suboptimal ventilation systems. Airborne transmission, recognized by the World Health Organization (WHO), poses a significant risk, influenced by various factors, including contact duration, individual susceptibility, and environmental conditions. Respiratory particles play a pivotal role in viral spread, remaining suspended in the air for varying durations and distances. Experimental studies provide insights into particle dispersion characteristics, especially in indoor environments where ventilation systems may be inadequate. However, experimental challenges necessitate complementary numerical modeling approaches. Zero-dimensional models offer simplified estimations but lack spatial and temporal resolution, whereas Computational Fluid Dynamics, particularly with the Discrete Phase Model, overcomes these limitations by simulating airflow and particle dispersion comprehensively. This paper employs CFD-DPM to simulate airflow and particle dispersion in a coach bus, offering insights into virus transmission dynamics. This study evaluates the COVID-19 risk of infection for vulnerable individuals sharing space with an infected passenger and investigates the efficacy of personal ventilation in reducing infection risk. Indeed, the CFD simulations revealed the crucial role of ventilation systems in reducing COVID-19 transmission risk within coach buses: increasing clean airflow rate and implementing personal ventilation significantly decreased particle concentration. Overall, infection risk was negligible for scenarios involving only breathing but significant for prolonged exposure to a speaking infected individual. The findings contribute to understanding infection risk in public transportation, emphasizing the need for optimal ventilation strategies to ensure passenger safety and mitigate virus transmission.

Background/Objectives: Sport persistence can be coded as an indicator of sport performance and commitment, incorporating personality traits such as resilience, adaptive coping, and positive personality traits. Thus, athletes do not merely persist in sporting activities but are qualitatively committed to them. Methods: In the present research, we used a qualitative methodology to investigate the factors underlying sport persistence, using Bronfenbrenner’s socio-ecological model. In total, 133 high school and college student-athletes were surveyed in a semi-structured interview study. We set the following research question: How do the factors involved in developing sport persistence vary across athletes’ gender, level of study, and level and type of sport? Data were analyzed along the lines of grounded theory. ATLAS.ti and IBM SPSS 22.0 statistical software were used for the analysis. Results: Our analysis divided individual motivation into intrinsic (health promotion, habituation, becoming a competitive athlete, self-improvement, self-actualization, relaxation, and sport enjoyment) and extrinsic motivation (family-related motivation, coach, social relationships, competition, livelihood, recognition). The cross-tabulation analysis revealed that contrary to the general trend, no significant differences can be experienced in the core motivational patterns contributing to sport persistence. However, significant differences could be detected concerning the level of education, level of sporting activity, and type of sport. Conclusions: Our findings not only shed light on the unique factors underlying sport persistence, but also challenge the trends observed in traditional sport motivation analyses. This insight could potentially revolutionize how we approach youth sport promotion and physical activity among young people, making our research highly relevant and impactful. Full article

Physical fitness (PF) has been identified as a critical health marker in youth and is significantly influenced by environmental factors, such as the specificity of training involved in different sports. This study investigated PF differences among young athletes who participated in water polo and volleyball to understand how different training programs and environments impact physical development. A sample of 98 youth athletes, including 46 water polo players (46% female; mean age: 13.07 ± 2.27 years) and 52 volleyball players (100% female; mean age: 13.80 ± 1.86 years) was assessed using Handgrip (HG), Standing Long Jump (SLJ), and Progressive Aerobic Cardiovascular Endurance Run (PACER) tests. Results were normalized against European percentile reference values and analyzed using the Mann–Whitney U test. The PACER test revealed a significant difference (U = 639, p < 0.001, r = −0.466), with water polo athletes exhibiting superior cardiorespiratory fitness compared to volleyball players. The HG test also showed significant differences (U = 1571, p = 0.007, r = 0.314), indicating greater grip strength in volleyball players. No significant difference was observed in the SLJ test. These findings underscore the importance of sport-specific training in youth athletes, but also the importance of well-rounded physical development training for all youth sports. Results suggest that practicing different sports that involve different training and environments is significantly associated with certain aspects of PF components. This awareness can guide grassroots coaches and trainers towards effective and balanced training strategies to promote performance and long-term health. Full article

Social work professionals experience high levels of burnout, emotional exhaustion, and secondary traumatic stress (STS). This paper reports the findings of a pilot test of the Burn-Not-Out programme that aimed to reduce social workers’ burnout, STS, and depressive symptoms and to enhance compassion satisfaction (CS), using the mixed methods evaluation methodology. Hong Kong social workers participated in the programme between December 2023 and March 2024 and completed pre- and post-programme self-administered online surveys including the Professional Quality of Life (ProQOL) and Patient Health Questionnaire (PHQ-9), healthy alongside self-constructed questions on boundary setting, and post-programme online focus group discussions. The results from 94 paired surveys revealed a concerning mental health profile of the participants at baseline, and, after programme participation, there were statistically significant reductions in burnout (Cohen’s d = 0.73) and depressive symptoms (Cohen’s d = 0.57) among the participants. The participants in the focus group reported that they valued the programme’s emphasis on healthy boundaries, one-on-one coaching, and the sense of being cared for, which contributed to their mental health improvement. This study highlights the urgent need for more research on the role of psychological capital in social workers’ resilience and calls for more empirical systemic interventions that can promote social workers’ mental wellness, with sustainable policies that ensure manageable workloads and adequate workplace support.

This study investigates dietary supplement use among rugby players and their general health, focusing on prevalence and underlying motivations. Involving 92 athletes, it examines the relationship between supplement usage, motivations, and health outcomes using the 36-item Short Form Health Survey and a 24-item ad hoc questionnaire. Findings reveal a high frequency of supplement usage, motivated by desires to enhance performance, appearance, and mood. Significant differences in health-related quality of life are found between users and non-users, particularly in mental health, social functioning, and emotional stability. Motivations like performance enhancement and body shape manipulation were linked to altered health perceptions, indicating the psychosocial impacts of supplementation. This study emphasizes the need to consider the holistic effects of supplements on athlete well-being, advocating for a balanced approach prioritizing both physical and mental health. It calls for increased awareness among athletes, coaches, and sports professionals about the potential risks and benefits of supplement use and the importance of informed decision-making. Additionally, it highlights the need for further research to understand the mechanisms of supplement use and its impact on athlete health, aiming to enhance sports science and promote overall athlete well-being in competitive environments.

Background/Objective: To address the opioid epidemic in Kansas City, Missouri, local health systems sought to implement a referral to peer recovery coaches (PRCs) for clients presenting with opioid use disorder. Client referrals were made primarily through health system emergency departments, where PRCs met clients to facilitate linkages to recovery support for up to twelve months. This study aimed to evaluate and improve program implementation with process mapping at three local health systems. Methods: Using a five-phase conceptual framework and three development and implementation domains, providers, administrators, and PRCs were interviewed to identify the process for recognizing clients with opioid use disorders and referring them to PRCs. Serial meetings were held to validate the process maps at three health systems and a distillation of key processes was created to guide future analyses and implementation efforts. Results: A detailed process map for each health system was developed, from which a high-level process map was created to support future implementation efforts. Health system-specific process maps varied, although conceptually coherent elements were identified across each system to diagram a recovery ecosystem to support client referrals to PRCs. Conclusions: By systematically assessing the implementation of the same program across different health systems, critical steps, along with their barriers and facilitators, were identified that can be used to understand the processes of care associated with outcomes and to guide future implementation efforts.

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) were originally developed in the late 1980s as a class of antidiabetic medication. However, research over the past decade has found them to be a safe and effective weight-loss agent, which has led to the approval of GLP-1 RAs such as Semaglutide as a supplement to lifestyle obesity interventions in multiple countries. When Semaglutide has become commercially unavailable, digital weight-loss services (DWLSs) have prescribed a compounded form of the medication—a practice in which health professionals formulate a replica of the commercial medication to serve ongoing patient needs. Although compounding has been relatively common over the past century, prominent medical bodies have argued that compounding a relatively novel medication such as Semaglutide represents a major safety risk. This study retrospectively compared the weight and side effect outcomes of patients from a large Australian DWLS whose lifestyle coaching was supplemented with either compounded or pure Semaglutide (both groups following the same titration schedule). All data were extracted from the service’s central data repository. To be included in the weight loss analysis, patients needed to have received a minimum of four monthly medication orders between June 2023 and May 2024 and have submitted weight data between 90 and 150 days after the arrival of their first order. All patients who received at least one medication order within the same period were included in the side effect analysis. The mean four-month weight loss percentage was statistically lower in the compounded Semaglutide group (N = 923, M = 9.11, SD = ±5.76) compared to those in the pure Semaglutide group (n = 1858, M = 9.87, SD = ±6.46), t (2032) = −3.15, p = 0.0017. A statistically lower proportion of patients in the compounded Semaglutide group (71.61%) reported at least one side effect than patients in the pure Semaglutide group (77.40%) during the study period, X² (1, N = 7683) = 32.32, p < 0.001. When side effects were disaggregated into severity categories, a statistical difference was only observed in mild side effects, X² (1, N = 7683) = 59.16, p < 0.001. A significantly higher rate of patients from the pure Semaglutide group achieved the ten (50.54% vs. 44.64%), X² (1, N = 7683) = 10.34, p < 0.001, and fifteen (21.42% vs. 12.78%), X² (1, N = 7683) = 30.43, p < 0.001, percent weight loss thresholds than patients from the compounded Semaglutide group. The findings indicate that compounded Semaglutide can be used as a component of tightly controlled DWLSs with slightly less effectiveness and but with slightly lower side effect incidence when compared to pure Semaglutide.

The impact of heat exposure on the health and performance of soccer players is a widely discussed topic. The purpose of this study is to provide a comprehensive overview of the international literature that has addressed this issue. To achieve this objective, we initially conducted a bibliometric analysis and a literature review of the main topics that emerged through bibliometric techniques. For the bibliometric analysis, we employed VOSviewer software (version 1.6.20.0) and used documents found in the Scopus database. The analysis ultimately included 133 documents published in 66 sources. Key journals and authors were identified, highlighting significant contributions to the field. Science mapping revealed collaboration networks and research focus areas such as physical health, safety, soccer performance, dehydration and hydration, physiological mechanisms and monitoring, nutrition, fluid intake, and cooling techniques. Based on the key areas highlighted in the identified clusters, which emerged from the co-occurrence analysis of the author keywords, the following three topics were developed in the literature review: (a) the physiology and health of football players; (b) performance impacts; and (c) strategies to prevent negative consequences. The review showed that high heat exposure can reduce the physical and cognitive performance of athletes and prove detrimental to their health. To mitigate the negative consequences, appropriate hydration strategies, heat acclimatization, and cooling techniques have been proposed. Our findings provide the international scientific community with comprehensive knowledge of the existing literature, laying the foundation for future research while simultaneously offering coaches and athletes the necessary theoretical knowledge to help improve safety and performance.

Digital weight-loss services (DWLSs) combining pharmacotherapy and health coaching have the potential to make a major contribution to the global struggle against obesity. However, the degree to which DWLSs compromise patient safety through the dispensation of Glucagon-like peptide-1 receptor agonist (GLP-1 RA) medications is unknown. This study retrospectively analysed the rate at which patients reported GLP-1 RA dispensing errors from patient-selected and partner pharmacies of Australia’s largest DWLS provider over a six-month period. The analysis found that 99 (0.35%) of the 28,165 dispensed semaglutide orders contained an error. Incorrect dose (58.6%) and unreasonable medication expiry window (21.2%) were the two most common error types. Most errors (84.9%) were deemed to have been of medium urgency, with 11.1% being considered high-urgency errors. Incorrect doses (45.5%) and supplies of the wrong medication (36.3%) comprised most errors reported in high-urgency cases. Female patients reported more dispensing errors than male patients (0.41% vs. 0.12%, p < 0.001). Similarly, reported dispensing error rates were highest among patients aged 18 to 29 years (0.6%) and 30 to 39 years (0.5%). This research provides preliminary evidence that GLP-1 RA dispensing errors within comprehensive Australian DWLSs are relatively low. Full article

Workplaces cause employees to adopt sedentary behaviors for most of their daytime, negatively impacting psychophysical health. A new office concept (UP150) was designed to reduce sedentary behaviors at work through architectural changes, proactive technologies, and wellness coaches (education to active lifestyles). The present study examined the effects of the UP150 concept, previously investigated in dedicated workspaces, with a 12-month longitudinal trial in a real worksite environment. Forty-eight desk workers comprised the experimental (EG) and control (CG) groups. All participants worked in the same working environment, having the UP150 features inserted in a usual working environment, but the CG was not allowed to interact with the UP150 specifics. During the experimental year, physical (physical activity, motor efficiency, and anthropometric features), clinical (metabolic parameters and cognitive-capacity-related parameters), and psychological (well-being and discomfort, job social and psychological perceptions, and perceived workload) features were assessed. The prolonged application of the UP150 procedure in a mixed working context for involvement in corporate policies positively affected EG workers’ physical (physical activity and motor efficiency increased, and body fat unchanged), clinical (blood glucose, insulin, and total cholesterol decreased; HDL increased), and psychological (well-being and social support raised; job demand and perceived workload lowered) parameters, confirming the previous studies.

Background: Influenza vaccination among athletes is a crucial area in sports medicine. This descriptive, cross-sectional study aims to explore the vaccination practices and intentions regarding influenza vaccines among young athletes. Methods: A structured, questionnaire-based study was conducted among students from the National School of Sports in Greece. The survey was conducted over the period of April to May 2023. Overall, 138 participants participated in the study. Results: More than half of the participants had received a flu vaccine in the past, but only 12.3% were vaccinated against influenza for 2022–2023. The main reasons seemed to be the lack of time (40.6%) and the idea that influenza does not lead to any serious health threats for the participants (36.2%). The main factor that affected their decision to get the flu vaccine or not was the need for more information regarding influenza vaccination (79%). Conclusions: The recent study showed low vaccination coverage among people of young age participating in sports activities. The qualitative views of the participants highlighted the significance of the lackof a well-organized information program provided by health professionals and coaches. Full article
