Objectives: Shoulder injury prevalence appears to be the highest among all injuries in CrossFit (CF) athletes. Nevertheless, there is no evidence deriving from prospective studies to explain this phenomenon. The purpose of this study was to document shoulder injury incidence in CF participants over a 12-month period and prospectively investigate the risk factors associated with their demographic, epidemiological, and functional characteristics. Methods: The sample comprised 109 CF athletes in various levels. Participants’ data were collected during the baseline assessment, using a specially designed questionnaire, as well as active range of motion, muscle strength, muscle endurance, and sport-specific tests. Non-parametric statistical tests and inferential statistics were employed, and in addition, linear and regression models were created. Logistic regression models incorporating the study’s continuous predictors to classify injury occurrence in CF athletes were developed and evaluated using the Area Under the ROC Curve (AUC) as the performance metric. Results: A shoulder injury incidence rate of 0.79 per 1000 training hours was recorded. Olympic weightlifting (45%) and gymnastics (35%) exercises were associated with shoulder injury occurrence. The most frequent injury concerned rotator cuff tendons (45%), including lesions and tendinopathies, exhibiting various severity levels. None of the examined variables individually showed a statistically significant correlation with shoulder injuries. Conclusions: This is the first study that has investigated prospectively shoulder injuries in CrossFit, creating a realistic profile of these athletes. Despite the broad spectrum of collected data, the traditional statistical approach failed to identify shoulder injury predictors. This indicates the necessity to explore this topic using more sophisticated techniques, such as advanced machine learning approaches. Full article

The aim of this pilot study is to explore the applications and relevance of heart rate (HR) monitoring in unified basketball during training and competition circumstances, focusing on athletes with intellectual disabilities. Six UB national team athletes were monitored using Polar Verity Sense heart rate monitors throughout training sessions and competitions. The data revealed considerable individual variability in HR responses among the athletes. These variations highlight the importance of personalized HR monitoring to accurately assess training loads and optimize performance. However, when applying HR monitoring, it is essential to account for factors that may affect data accuracy, including consistency in device placement and environmental stressors such as competition anxiety. Additionally, athletes with cardiovascular comorbidities may display atypical HR patterns, requiring cautious interpretation of HR thresholds. Although the small sample size limits the broader applicability of the findings, this study explores the application and relevance of HR monitoring, highlighting the need for future research to further validate its effectiveness.

This study explores the predictive factors influencing sport coaches’ perceived performance levels following an 18-month mentor-based education program. The study employed a quasi-experimental, pre-test/post-test control group design to assess changes in perceived coach performance over time. The experimental group participated in six group gatherings and at least 15 individual mentoring sessions over 18 months, while the control group received no intervention. Participants were recruited from a non-formal coach education program run by the Norwegian Olympic Sports Center (NOSC), requiring recommendations from their respective sport federations. Of the 159 coaches who applied, 73 were selected for the program and invited to participate, along with 29 additional coaches from specialized high schools for elite sports, forming a total sample of 98 coaches (69 in the experimental group, 29 in the control group) at pre-test. The sample consisted of 61 males (62%) and 37 females (38%), aged 26 to 71 years (M = 38.3, SD = 8.3), representing over 20 sports, with handball (15.3%), cross-country skiing (10.2%), soccer (7.1%), and track and field (7.1%) being the most common. Data collection included an online questionnaire measuring perceived coach performance, coaching hours, age, and dimensions of the coach–athlete working alliance (task, bond, and goal development). After 18 months, 75 coaches completed the study, yielding a response rate of 73.5%. Hierarchical regression analyses revealed that coaches’ ages, weekly coaching hours, baseline perceived performance, and task development within the coach–athlete working alliance positively predicted their performance perception post-test. Participation in the mentor-based program also had a significant positive effect. However, neither bond nor goal development in the working alliance predicted performance perception. These findings underscore the importance of mentoring, structured self-reflection, and task-focused coaching strategies in enhancing coaching effectiveness. The results have implications for coach education programs seeking to foster professional growth and performance development. Full article

Background: The main objectives of this study were to analyze the effect of early specialization in swimming and to observe the general patterns of success of two different sport specialization models [Spanish (SPA) and United States of American (USA) swimmers] participating in World Championships (WCs) and Olympic Games (OGs) between the years 2006 and 2021 of all swimming strokes and distances. Methods: Descriptive analyses and contingency tables were examined for all the variables. Explanatory models of the z scores were estimated from age depending on the events’ distances and strokes. Quadratic regression models were developed to capture the behavior of the variable time with parabolic functions, and the significance of the global model and the predictor variables (age) were also evaluated. In addition, the optimal age (peak performance) as well as the curvature of the model were analyzed. These models were compared between SPA and USA swimmers. Results: The results showed that the main differences in the patterns to success between SPA and USA were the earlier participation of USA swimmers in high-level competitions, as well as the greater number of participants for all the strokes, events, genders, and competitions. Age peak performance in short distances was lower for Spanish swimmers, obtaining the opposite situation for long distances. Conclusions: Being a finalist in junior WCs did not influence success in the finals of the senior WCs and OGs. Main differences in general patterns of success between SPA and USA showed younger swimmers participating in short-distance events, backstroke, and butterfly for USA swimmers and older swimmers taking part in butterfly and short-distance events for SPA.

Urban forest parks play a vital role in promoting physical activities (PAs) and providing cultural ecosystem services (CESs) that enhance citizens’ well-being. This study aims to reevaluate CESs by focusing on the physical activity experiences of park visitors to optimize park management and enhance citizen satisfaction. This study utilized social media data and employed natural language processing techniques and text analysis tools to examine experiences related to physical activities in Beijing Olympic Forest Park, Xishan Forest Park, and Beigong Forest Park. A specialized sports activity dictionary was developed to filter and analyze comments related to PA, emphasizing the impact of natural environments on enjoyment and participation in PA. The importance–performance analysis (IPA) method was used to assess the service characteristics of each park. The findings reveal that urban forest parks are highly valued by citizens, particularly for their natural landscapes, leisure activities, and the emotional fulfillment derived from PA, with 82.58% of comments expressing positive sentiments. Notably, appreciation for natural landscapes was exceptionally high, as evidenced by the frequent mentions of key terms such as ‘scenery’ (mentioned 2871 times), ‘autumn’ (mentioned 2314 times), and ‘forest’ (mentioned 1439 times), which significantly influence park usage. However, 17.11% of the reviews highlighted dissatisfaction, primarily with the management of facilities and services during sports and cultural activities. These insights underscore the need for performance improvements in ecological environments and sports facilities. This study provides a novel perspective on assessing and optimizing urban forest parks’ functions, particularly in supporting active physical engagement. The rich CESs offered by these parks enhance physical activity experiences and overall satisfaction. The findings offer strategic insights for park managers to better meet citizens’ needs and improve park functionality. Full article

In alignment with European policies regarding intergenerational sports, this study seeks to integrate existing evidence- (i.e., umbrella review) and eminence- (i.e., international validated educational courses for coaches) based knowledge on judo training across the lifespan. For evidence knowledge, searches of the Google Scholar, ISI-WoS, PubMed, and Scopus databases (PROSPERO ID: CRD42024535420) for studies focused on training youth and older judo practitioners, with no time restriction up to April 2024, were conducted. This resulted in 16 systematic reviews meeting the inclusion criteria, with an “excellent” (n = 6), “good” (n = 7), and “fair” (n = 3) quality according to the NIH tool. With a large sample size (n = 372,655), the reviews focused on wellbeing (n = 9; bone status, injuries, and psychophysical effects) and performance (n = 7; athlete success, combat time, rapid weight loss, and the Special Judo Fitness Test), examining athletic levels (novices to Olympics), sex, and age (children to older adults). For eminence knowledge, the International Judo Federation Academy courses encompassed the “Undergraduate Certificate as Judo Instructor” (UCJI), which provides a comprehensive structure for teaching judo, including techniques, moral code, roles, responsibilities, refereeing, safety, and age-specific belt examination requirements and progression, and the “Educating Judo Coaches for Older Practitioners” (EdJCO) curricula, which provide theoretical and applied modules (e.g., ageing, health, and organisation) to train older judo practitioners. The findings were summarised in a framework, highlighting the most relevant aspects of intergenerational judo programmes (i.e., aims, key characteristics, coaches’ roles, barriers, and facilitators). To develop a comprehensive educational intergenerational judo methodology, future research should examine coaches’ and practitioners’ opinions on intergenerational judo activities carried out in different national contexts.

The literature on inclusive research has established its relationship with self-advocacy for people with intellectual disabilities. Self-advocacy has been described as both a requirement and a result of inclusive research. Additionally, the process of becoming an inclusive researcher can be seen as self-advocacy for people with intellectual disabilities. As inclusive research continues to become more prominent, and more people with intellectual disabilities become inclusive researchers, we need to continue to consider this fundamental relationship and how self-advocacy and inclusive research can inform and support each other. In this paper, we first discuss the history of self-advocacy and inclusive research and what inclusive researchers have shared about the relationship between self-advocacy and inclusive research. We then present the experiences of an inclusive researcher with intellectual disability with self-advocacy and how the process of becoming an inclusive researcher impacted those experiences. We conclude the paper with reflections on how future inclusive research should consider the role of self-advocacy. Full article

Swimming, an Olympic sport with diverse distances and energy systems, requires early specialization for elite success. High intensity interval training (HIIT) is a fundamental method used by swimmers to enhance performance, offering both aerobic and anaerobic benefits. This study aimed to examine the effects of a 12-week HIIT program with varying volumes on adolescent swimmers’ performance parameters. A total of 50 participants were divided into three groups High Intensity Low Volume (HILV), Moderate Intensity Moderate Volume (MIMV), Low Intensity High Volume (LIHV), and their training sessions consisted of 10 sets with 60 s rest intervals between repetitions and 3 min rest intervals between sets. The intensity was determined based on a pre-test 100 m times. The results indicate significant improvements in anthropometric measurements, including weight, Body Mass Index (BMI), and body fat percentage, within each group, with no significant differences between groups. Swimming performance for various distances (50 m, 100 m, 200 m, and 800 m) showed significant temporal improvements in all groups, with stroke parameters such as stroke rate and length also exhibiting significant improvements (p < 0.05). Resting heart rate and swimming performance at 100 m and 200 m differed significantly between groups, highlighting the impact of training volume on specific outcomes. In conclusion, this study highlights the positive impact of interval training on the swimming time (50 m, 100 m, 200 m, and 800 m), stroke rate (SR), strokes per length (SPL), stroke length (SL), Borg scale (BS) for various distances, emphasizing the need for tailored training programs to maximize their development and potential.

Planning the medical services for the triathlon competition at the 2020 Tokyo Olympic and Paralympic Games was predicted to be challenging because of possible last-minute changes related to the COVID-19 pandemic and abnormally high temperatures. Therefore, event planners organized and executed a disaster medical care plan, a plan for providing care during emergencies. Based on the basic medical plan for all venues provided by the Tokyo 2020 Organizing Committee, planners for the triathlon venue prepared a medical care plan according to the CSCATTT principles: Command and control, Safety, Communication, Assessment, Treatment, Triage, and Transport. After the event, planners evaluated the number of COVID-19, heatstroke, and injury cases at the venue. The events were conducted without spectators in July and August 2022 because at the last minute, planners held the event without spectators. The triathlon competition involved 638 individuals, including athletes and staff. In total, 7 cases of injuries, 3 cases of mild heatstroke, and 13 other cases were reported, with only 2 requiring emergency transportation. No cases of COVID-19 were reported from the triathlon venue, including during the observation period after the event. This medical plan was effective in preventing heatstroke and COVID-19 cases during the big event. Efficiently and effectively responding to various situations is possible in a shorter period by planning large-scale medical services for such special circumstances according to CSCATTT, a principle of disaster medical care.

The concept and practice of social inclusion in sport are still undefined, causing confusion both in the field of sport policy and practice. According to the United Nations (UN), a conceptual and analytical work on what constitutes inclusion is needed. Therefore, this study aims to define social inclusion in sport for people with disabilities by reviewing the existing literature. Using a scoping review framework, articles related to a possible definition of social inclusion in sport or to the elements of this definition were reviewed. For the eighteen (18) articles selected, the focus was on 152 statements, which were grouped into 6 main categories, namely: policy (29), fundamental conditions (28), key elements (30), soft skills (20), field gaps (31), and best practices (14). Ten keywords were extracted from each of the six categories using the free online program cortical.io. All 60 keywords were then compared with each other. After deleting the duplicates, 24 keywords remained, which were classified into five major categories: (1) key people, (2) key environments, (3) key ways to use, (4) key benefits, and (5) key barriers, in order to create a descriptive definition of social inclusion in sport for people with disabilities that can contribute to the goals of the UN 2030 Agenda. In addition to the definition, relevant issues were also raised for in-depth discussion and further research. Full article

Since the UN Convention on the Rights of Persons with Disabilities (CRPD) was created, segregation of persons with disabilities is no longer allowed. Separate schools, sheltered workshops, and isolated social care homes impede inclusion and must be banned. Sport is a remarkable exception to this general principle. The CRPD explicitly states that persons with disabilities should have the opportunity to organize, develop, and participate in disability-specific sporting activities. This contribution—focusing on the Paralympics and Special Olympics—examines why the CRPD allows and encourages disability-specific sporting competitions, despite (or perhaps due to) its radical choice for inclusion. Beyond that, this contribution asks the obvious follow-up question: if disability-specific competitions are allowed, how can the criteria for participation be determined in a manner consistent with the CRPD? The CRPD opposes a medical approach to disability, yet that approach is often used in selection criteria. Although this contribution primarily focuses on sports, the impact is wider: it raises questions on inclusion and how to assess disability. Full article

Ski mountaineering, a new Olympic winter sport involving both climbing and descending snowy slopes, requires considerable physical and technical abilities, as well as highly specialized equipment. Herein, we briefly describe this equipment and its influence on performance and consider potential future advances. Skis, boots, and bindings must be light enough to facilitate climbing uphill (in which as much as 85% of the total racing time is spent) and, at the same time, provide stability and safety in often-challenging descents. A skier must be able to easily and rapidly attach and remove the adhesive skins under the skis that provide grip while skiing uphill. Poles and their baskets must be designed optimally to transfer propulsive force and help maintain balance. Despite the popularity of ski mountaineering, research on this sport is scarce, and we indicate a number of areas wherein improvements in equipment could potentially advance both performance and safety. Such advances must be based on a better understanding of the biomechanics of ski mountaineering, which could be obtained with novel sensor technology and can be best achieved via more extensive collaboration between researchers, skiers and their coaches, and manufacturers of ski mountaineering equipment.

Whether it is the Summer Olympics or the Winter Olympics, in order to resolve potential sports disputes, the Court of Arbitration for Sport (CAS) sets up a special ad hoc tribunal in the host city of the Olympic Games. Although CAS ad hoc rules have many similarities with ordinary procedures, they are different in terms of the legal basis, legal remedies, and certain procedural rules. During the Beijing 2022 Winter Olympics (Beijing 2022), the CAS Ad Hoc Division and the CAS Anti-Doping Division heard a total of seven cases. These cases involve issues such as provisional suspension of games, protection of minors, unreasonable delays in test results, cancellation of award ceremonies, and the timing of disputes. the CAS Ad Hoc Division decisions on the above issues can be regarded as the latest developments in the application of international sports arbitration rules.

This study investigated the relationship between peak oxygen uptake and ventilatory threshold 1 (VT1) and 2 (VT2) with the Special Wrestling Fitness Test variables. Thirteen wrestlers (male: six; female: seven) of Olympic freestyle wrestling were assessed. The Pearson’s correlation coefficient (p < 0.05) was used to establish the relationship between variables. A positive correlation was found between VT1 with throws in set B (r = 0.77; p = 0.002; 95%CI = 0.37–0.93), total throws (r = 0.73; p = 0.004; 95%CI = 0.30–0.91), heart rate recovery (r = 0.58; p = 0.036; 95%CI = 0.05–0.86), and test index (r = −0.60; p = 0.031; 95%CI = −0.86–0.07); between VT2 and throws in set B (r = 0.57; p = 0.043; 95%CI = 0.01–0.86); and between peak oxygen uptake with throws in set B (r = 0.77; p = 0.002; 95%CI = 0.39–0.93), throws in set C (r = 0.64; p = 0.02; 95%CI = 0.12–0.89), and total throws (r = 0.72; p = 0.006; 95%CI = 0.28–0.91). In conclusion, the peak oxygen uptake and ventilatory thresholds correlated with specific Special Wrestling Fitness Test variables. Full article

People with intellectual disability lack opportunities to engage in sports, although the benefits of doing so may be even greater for them. One option is to encourage their inclusion in mainstream sports clubs that exist in nearly all European communities. Although there is a growing knowledge base within organisations such as Special Olympics in adjusting sports to meet the needs of people with intellectual disability, inclusion in community clubs raises additional challenges. This exploratory study aimed to garner the experiences of coaches alongside those of clubs members—with and without disabilities—in 12 community sports clubs in three European countries. In all 20 coaches and 51 members took part in semi-structured interviews. A thematic content analysis was used to devise a conceptual model describing an inclusive sports club. The overarching theme was that inclusive clubs require an ongoing balancing between a focus on sporting skills and performance, with managing the needs and characteristics of the players and the inter-relationships among them. Six subthemes were identified that described the core strategies to the effective functioning of the clubs. However, the vision and commitment of coaches was crucial and their recruitment was the main challenge the clubs faced. In addition, new opportunities for training coaches are needed to support the extension of inclusive clubs across a range of sports and locations. Continuing research could usefully identify the benefits to club members and identify sport-specific adaptations required to make clubs more fully inclusive. Full article
