The Holistic MAP to Athletic Wellness: A Narrative Review

You can’t use an old map to explore a new world. —Albert Einstein We are at a fork in the evolutionary road to athletic wellness. While elite athletes are achieving unsurpassed magnificence in strength, endurance, power, and skill, much of our population is experiencing a devolution from poor lifestyle choices that negatively influence both human and planetary health. The alarming descent to a lesser state of collective health puts most of our sedentary population at greater risk of injury, disease, dysfunction, and chronic pain. The father of sports medicine, Herodicus, was the first known physician to recommend exercise for the treatment of disease, recognizing its powerful influence on quality of life and health span. Athletic participation is linked with improved physical and mental health, as well as reduced obesity, disability, and disease. However, sports may also result in physical, psychological, social, athletic, professional, and financial repercussions.1 The international scientific community has rallied with tremendous research over the past decades to promote sustainable athletic participation and healthy active living. While tremendous efforts have been launched to engage in this challenging endeavor, a significant problem remains due to the multifactorial nature of athletic injuries. The full potential for body-mind-spirit resilience and wellness is achieved through the balance of all interdependent components, considering all possible biological, psychological, social, and spiritual factors influencing each athlete to establish an individualized, holistic mindset, agility, and personalization (MAP) approach toward injury-free sports and active living.

Epidemiology of ankle sprain and chronic ankle instability in elite adolescent dancesport athletes

ABSTRACT Background Dancesport is performed in high-heeled shoes. Dancesport athletes may have a higher prevalence and incidence of ankle sprains, which can affect their performance. However, the occurrence of ankle sprains among dancesport athletes remains unclear. This study aimed to determine the prevalence and incidence of ankle sprains among elite dancesport athletes and to investigate the related information. Method We conducted a mixed descriptive epidemiological study (cross-sectional and longitudinal) involving 198 elite adolescent dancesport athletes, using past medical records and questionnaires administered to the participants. Data on the occurrence of ankle sprains among all participants were compiled using medical records and information on injury mechanisms, missed days, severity types, and countermeasures for ankle sprains were collected. The prevalence of chronic ankle instability (CAI) among the participants was assessed using a questionnaire. Following the initial survey, we conducted a one-year follow-up study to investigate the incidence of ankle sprains, incidence rate per 1000 exposure hours, and recurrence of ankle sprains. Result The cross-sectional study and longitudinal study included 198 participants and 92 elite dancesport athletes, respectively. The prevalence of ankle sprains and CAI was 49.5% and 45.1%, respectively. Of all ankle sprains, 88% were medial injuries. The most common injury mechanisms were turning (46.9%) and jumping (46.9%). The average number of missed days due to ankle sprains was 11.2 days. Most injuries were managed with rest, and only one male athlete underwent surgery due to an ankle sprain sustained during dancing. During the one-year follow-up, the incidence of ankle sprains, incidence rate per 1000 exposure hours, and recurrence rate of ankle sprains were 46.6% (male, 41.2%; female, 48.8%), 0.65 ankle sprains/1000 h, and 35.3%, respectively. No sex-related differences were observed. Conclusion It is crucial to focus on the occurrence of ankle sprains and CAI in dancesport athletes with high heels. Future research should clarify the impact of ankle sprains on dancesport performance and develop preventive measures to reduce the incidence and recurrence of these associated injuries.

Management and Return to Play of the Elite Athlete for Common Sports-Related Injuries About the Foot

Foot injuries are one of the most commonly injured areas of the body in many collegiate and professional sports. The wide range of pathology, pathophysiology, mechanisms of injury, differences in sport demands, evolution of treatment, and variable return-to-play time lines make it difficult, at times, for physicians to treat these injuries. Modern diagnostic tools, surgical treatment devices, and rehabilitation protocols have allowed for more accurate and rapid diagnosis, an improved ability to reestablish normal anatomy, and accelerated return to play for many sports-related foot injuries. This summary will provide the most up-to-date, evidence-based treatment options for common sports-related foot injuries along with the authors’ preferred method of treatment and return-to-play algorithms for the elite athletes.

Transferability of the competences acquired in the elite athlete career to the project manager role analysis

What personal competences of successful project managers are determined by their former career as an elite athlete? To answer the question, comprehensive research is carried out, implemented as part of the EEIG-EU/P-Kr/06.12/23 project. The primary aim is to establish conclusively which particular personality traits, identified and analysed using the Big Five Inventory-2 and supplemented by structured interviews, directly contribute to the success of former elite athletes transitioning into roles as effective project managers. We found that successful project managers who were also elite athletes possess personality traits that can be identified as positive determinants of success in either sport or professional careers. Among these personality traits, we can include a low level of neuroticism and a high level of conscientiousness, then extraversion and agreeableness. This paper contributes to a nuanced understanding of how the realms of sports and management intersect and overlap. The presented paper can serve as a basis for further research in the field of personality psychology and management studies.

Variations in Personality Traits Among Top Judo Referees from 2018 to 2022 Based on Gender Differences

The personality traits of top judo referees are crucial for fair decision-making in elite competitions, shaping the experience for athletes, coaches, and spectators. This study examines potential differences in personality traits among 63 referees from the World Judo Tour between 1 January 2018 and 31 December 2022. Factors analyzed include completing the IJF Academy course Level 1, elite athlete status, number of officiated events, performance ratings, and participation in the Olympic or Paralympic Games. Our research shows that older referees tend to exhibit greater extraversion, whereas less experienced officials show lower levels of this trait. Referees with limited experience generally demonstrate higher agreeableness than their more experienced counterparts. Female referees and those with top performance ratings display greater conscientiousness than male referees. Completing the IJF Academy course is associated with lower neuroticism, while lower performance ratings are linked to higher neuroticism. Openness tends to decrease with increased officiating experience, with less experienced referees showing higher levels of this trait. In conclusion, competitive experience, training completion, and officiating tenure are associated with specific personality traits among judo referees, highlighting the importance of continuous training for effective officiating. The analysis of personality traits revealed no statistically significant differences between male and female referees in the dimensions measured by the BFI (Big Five Inventory). This indicates that the levels of extraversion, agreeableness, conscientiousness, neuroticism, and openness were similar for both genders, with no significant variation in how these traits were expressed.

Shoulder girdle injuries in volleyball players: structure, symptoms, cause and prevention. A narrative review

Shoulder joint injuries are a major concern in volleyball, particularly among elite athletes who undergo rigorous training sessions and frequently participate in competitions. Given that volleyball is a polystructured sport that requires volleyball players to constantly change the amplitude of movement in the shoulder joint, frequent injuries such as subacromial impact syndrome, compression of the suprascapular nerve, bursitis and tendinitis of the rotator cuff occur. In order to prevent injuries, prevention programs are increasingly introduced today. Consequently, the aim of this research was to describe the structure and prevention of shoulder girdle injuries in volleyball players. Prevention programs developed by researchers have been shown to be effective in reducing the prevalence of shoulder injuries. Prevention programs include adequate warming up, strengthening and stretching of the muscles of the shoulder girdle, as well as correct execution of technical elements. The development and implementation of individualized prevention and rehabilitation programs can significantly contribute to reducing the risk of injuries and prolonging the sports career of volleyball players.

Erythrocyte nicotinamide adenine dinucleotide concentration is enhanced by systematic sports participation

BackgroundNicotinamide adenine dinucleotide (NAD+), nicotinamide adenine dinucleotide phosphate (NADP+), and their reduced forms (NADH and NADPH) are the vital cofactors for most cellular oxidation/reduction reactions and therefore influence most critical pathways in cellular metabolism. This study aimed to predict the trends of age-related changes in erythrocyte NAD+ and NADP+ concentrations in elite athletes compared to untrained controls and to assess whether life-long physical training stimulates favorable adaptations in erythrocyte NAD(P)+ concentrations.MethodsErythrocyte concentrations of NAD+ and NADP+ were measured in 68 elite endurance runners (20–81 years), 58 elite sprinters (21–90 years), and 62 untrained individuals (20–68 years). Linear regression analyses were performed to estimate longitudinal relationships and cross-sectional rates of change between age and erythrocyte NAD+ and NADP+ levels. One-way analysis of variance was used to determine differences between the studied groups.ResultsIn all three groups, the erythrocyte NAD+ and NADP+ concentrations significantly decreased with advancing age, suggesting gradual deterioration of NAD-related regulatory functions in older individuals. However, the concentration of erythrocyte NAD(P)+, regardless of age category, was higher in the athletic groups compared to less active controls.ConclusionsOur research shows that systematic sports participation, especially of a sprint-oriented nature, can be treated as a natural and effective strategy promoting cellular NAD(P)+ anabolism and thus cells’ energy and redox metabolism.Trial registrationThe study was retrospectively registered in the clinical trials registry on 2021-11-09 (NCT05113914).

Three Scientist Practitioners: Self-Reflecting and Narrating Professional Careers and Daily Activities

In this paper, we present three narratives disclosing our experiences as scientist practitioners. Each author reflected on their career trajectories, and the natural interdependence of science and practice, and provided an illustration capturing the main features of their dual role. These three illustrations included collaboration with an integrated (practice and research) team, a deepened self-reflection, and an abbreviated case study with an elite athlete. Consistent with the limited literature on the scientist practitioners model, we share universal career trajectories as academicians who are intensely engaged in sport psychology practice (e.g., practice benefits from science, and vice versa). Some specific elaborations on the interrelated roles and tasks are the benefits of a journal reviewer’s role and the parallel functions of ecological validity (in research) and immersion (in practice) as bridging and balancing the scientist practitioner and scientist practitioner shift in daily activities, professional roles, and career phases. We offer practical considerations regarding the value of asking problem-solving-oriented questions, creating one’s own principles to navigate the dual role, and reminding ourselves about the interdependence of theory and practice.

Applications of AI in martial arts: A survey

Artificial intelligence (AI) has become an interdisciplinary subject that integrates digital image processing, machine learning, and computer science, etc. A lot of work in martial arts benefits from AI technology. In this paper, we highlight and summarize the applications of AI in martial arts and indicate the main progress of related studies. Through the investigation of martial arts styles, tasks, data acquisition methods, and algorithm improvements, a paradigm that represents a possible technological process for an intelligent martial arts training system was summarized. These applications bring more scientific training and more effective technical analysis to martial arts. Furthermore, this paper delves into specific AI applications in areas such as action recognition, pose estimation, action evaluation, elite athlete support, sports betting, health care, animation generation, and competition field segmentation. By exploring these areas, the research prospects of AI applications in martial arts are comprehensively discussed. This paper inspires further research on martial arts by using AI, which includes helping researchers expand their research ideas and research methods, identify frontier issues, and innovate based on existing research.

Cardiac Function and Structure before and after Mild SARS-CoV-2 Infection in Elite Athletes Using Biventricular and Left Atrial Strain.

Myocardial involvement has been observed in athletes following SARS-CoV-2 infection. It is unclear if these changes are due to myocardial damage per se or to an interruption in training. The aim of this study was to assess cardiac function and structure in elite athletes before and after infection (INFAt) and compare them to a group of healthy controls (CON). Transthoracic echocardiography was performed in 32 elite athletes, including 16 INFAt (median 21.0 (19.3-21.5) years, 10 male) before (t0) and 52 days after (t1) mild SARS-CoV-2 infection and 16 sex-, age- and sports type-matched CON. Left and right ventricular global longitudinal strain (LV/RV GLS), RV free wall longitudinal strain (RV FWS) and left atrial strain (LAS) were assessed by an investigator blinded to patient history. INFAt showed no significant changes in echocardiographic parameters between t0 and t1, including LV GLS (-21.8% vs. -21.7%, p = 0.649) and RV GLS (-29.1% vs. -28.7%, p = 0.626). A significant increase was observed in LA reservoir strain (LASr) (35.7% vs. 47.8%, p = 0.012). Compared to CON, INFAt at t1 had significantly higher RV FWS (-33.0% vs. -28.2%, p = 0.011), LASr (47.8% vs. 30.5%, p < 0.001) and LA contraction strain (-12.8% vs. -4.9%, p = 0.050) values. In elite athletes, mild SARS-CoV-2 infection does not significantly impact LV function when compared to their pre-SARS-CoV-2 status and to healthy controls. However, subtle changes in RV and LA strain may indicate temporary or training-related adaptions. Further research is needed, particularly focusing on athletes with more severe infections or prolonged symptoms.

Aging Skeletal Muscles: What Are the Mechanisms of Age-Related Loss of Strength and Muscle Mass, and Can We Impede Its Development and Progression?

As we age, we lose muscle strength and power, a condition commonly referred to as sarcopenia (ICD-10-CM code (M62.84)). The prevalence of sarcopenia is about 5–10% of the elderly population, resulting in varying degrees of disability. In this review we emphasise that sarcopenia does not occur suddenly. It is an aging-induced deterioration that occurs over time and is only recognised as a disease when it manifests clinically in the 6th–7th decade of life. Evidence from animal studies, elite athletes and longitudinal population studies all confirms that the underlying process has been ongoing for decades once sarcopenia has manifested. We present hypotheses about the mechanism(s) underlying this process and their supporting evidence. We briefly review various proposals to impede sarcopenia, including cell therapy, reducing senescent cells and their secretome, utilising targets revealed by the skeletal muscle secretome, and muscle innervation. We conclude that although there are potential candidates and ongoing preclinical and clinical trials with drug treatments, the only evidence-based intervention today for humans is exercise. We present different exercise programmes and discuss to what extent the interindividual susceptibility to developing sarcopenia is due to our genetic predisposition or lifestyle factors.

Survival and longevity among male Australian elite athletes: A retrospective cohort study.

To quantify and compare survival and longevity in three populations of male Australian elite athletes, relative to sex- and age-matched referents from the general population. Retrospective cohort study. This study comprised a census of three populations of male Australian elite athletes (i.e. N = 10,502 Australian Football League players, N = 803 national team rugby union players, and N = 1527 Olympic athletes) who debuted from 1-JAN-1921 to 31-DEC-2023. Nonparametric relative survival analysis was conducted using the Kaplan-Meier estimator to generate survival curves, the Pohar Perme method and a log-rank type test to estimate and compare net survival, and the life years difference measure to estimate longevity gains or losses. Olympic athletes had a continuous gain in net survival post-debut, with an average life years difference of 3.40 (95 % confidence interval 2.30 to 4.49) years at the maximum follow-up time. Australian football and rugby union players initially had modest gains in net survival post-debut, followed by a gradual decline in net survival, with average life years differences of 0.31 (95 % confidence interval -0.03 to 0.65) and -0.67 (95 % confidence interval -1.87 to 0.53) years at the maximum follow-up time, respectively. Net survival was significantly different across the three cohorts (test statistic 21.8; degrees of freedom = 2; p < 0.001). Expected survival benefits were offset in elite male Australian football and rugby union players. Further research examining cause-specific mortality is warranted to elucidate the underlying reasons for the observed lack of expected survival benefit in Australian football and rugby union players.

Atrial Fibrillation in Elite Athletes: A Comprehensive Review of the Literature.

Although the benefits of exercise training have been shown repeatedly in many studies, its relationship with the occurrence of atrial fibrillation (AF) in competitive athletes still remains controversial. In the present review, we sought to demonstrate a comprehensive report of the incidence, pathophysiology, and therapeutic approaches to AF in elite athletes. A 2 to 10 times higher frequency of AF has been shown in many studies in high-intensity endurance athletes compared to individuals who do not exercise. Moreover, a U-shaped relationship between male elite athletes and AF is demonstrated through this finding, while the type and the years of physical activity seem to relate to AF development. A strong correlation seems to exist among the type of exercise (endurance sports), age (>55 years), gender (males), and the time of exercise training, all contributing to an increased risk of AF. The pathophysiology of AF still remains unclear; however, several theories suggest that complex mechanisms are involved, such as bi-atrial dilatation, pulmonary vein stretching, cardiac inflammation, fibrosis, and increased vagal tone. Elite athletes with AF require a comprehensive clinical evaluation and risk factor optimization, similar to the approach taken for nonathletes. Although anticoagulation and rate or rhythm control are cornerstones of AF management, there are still no specific guidelines for elite athletes.

‘Yes, I’m an Elite athlete and I’m Gay’: Experiences of elite gay male athletes in Spain

There is a broad academic consensus that sexual minorities have been marginalised in sports culture. The present research is the first to explore the experiences of gay male elite athletes in Spain. Drawing on 11 semi-structured interviews with these athletes, this paper focuses on the experiences of being gay in elite sport. Guided by Connell's concept of hegemonic masculinity and the process of individualisation, our findings show that all the athletes have experienced or witnessed homonegativity, but at the same time have been empowered by sport. These athletes are paving the way for a more diverse masculinity in sport and making male homosexuality more visible. For continued improvements, it is important to implement more effective, inclusive sports policies and to introduce specific training for stakeholders.

Effects of Perceptual-Cognitive Training on Anticipation and Decision-Making Skills in Team Sports: A Systematic Review and Meta-Analysis.

Team sports require athletes' exceptional perceptual-cognitive skills, such as anticipation and decision-making. Perceptual-cognitive training in laboratories aims to enhance these abilities. However, its effectiveness in real-game performance remains controversial, necessitating a systematic review and meta-analysis to determine optimal training methods. Following the PRISMA guidelines, we searched databases (e.g., PubMed, WOS, Scopus, and EBSCO) for relevant studies published before November 2023, assessed study quality, extracted important characteristics, and conducted a meta-analysis using Stata 15.1. This study was registered in PROSPERO (CRD42023494324). A total of 22 quantitative studies involving 45 effect sizes were included. Perceptual-cognitive training positively influenced elite athletes' anticipation and decision-making. However, its transfer effect on real-game performance improvement (ES = 0.65) was inferior to laboratory performance improvement (ES = 1.51). Sub-group analyses indicated that the effects of training interventions varied based on stimulus presentation and intervention duration. Based on our findings, we concluded that while perceptual-cognitive training improved on-court performance, its transfer effects were limited. To maximize effectiveness, future interventions should use virtual reality to present training stimuli and incorporate participants' sport-specific responses to reflect real-game scenarios.

Exploring print media coverage of elite athletes' mental illness between 2010 and 2023 in Germany: a quantitative content analysis.

Recently, the stereotype of elite athletes' invulnerabilty has begun to be challenged by an increasing number of elite athletes who talk openly about struggling with mental health. Relatedly, previous research has focused primarily on specific incidents like the media's portrayal of personal disclosures. The purpose of this study was to expand this perspective and give a systematic overview of media coverage related to elite athletes' mental illness by examining more than one decade (2010-2023) of German print media reporting. Specifically, we were interested in changes over time and between broadsheet and tabloid press regarding content-related and formal aspects. Based on a systematic search and screening process in eleven German newspapers and magazines, 699 print media articles were analyzed with a codebook, forming a framework of content-related (reported mental disorder; central thematic focus; sources of comments and quotations; perspectives on the high-performance sports system) and formal categories (article genre; elements of responsible journalism). Univariate analyses and binary logistic regression models were used to examine changes over time (2010-2016 vs. 2017-2023) and differences between types of press (tabloid vs. broadsheet press) regarding content-related and formal characteristics. The results indicate an enhanced awareness towards the topic of mental illness and those affected in recent years within German print media. This was demonstrated by the increased integration of responsible reporting elements, the inclusion of diversified perspectives and the considerate selection of content. Despite this positive trend over time, the findings also suggest that media reporting in the tabloid press bears an increased risk for inappropriate storytelling, focusing primarily on personal tragedies. As personal fate of prominent figures like elite athletes will always meet great interest in the public, it is of utmost importance that the media report responsibly and promote critical thinking in society. The study shows the media's willingness to question conventional ideals embedded in the sports culture and take a more critical approach to the topic of mental illness in high-performance sports. By demonstrating a greater understanding of the importance and the seriousness of the issue, the media might also contribute to improved mental health awareness in society.

Comparative Analysis of Heart Rate Variability and Arterial Stiffness in Elite Male Athletes after COVID-19.

This study investigated the long-term cardiovascular effects of coronavirus disease (COVID-19) in elite male athletes by comparing the heart rate variability (HRV), arterial stiffness, and other cardiovascular parameters between those with and without prior COVID-19 infection. Methods: This cross-sectional study evaluated 120 elite male athletes (60 post COVID-19, 60 controls) using anthropometric measurements, body composition analysis, pulmonary function tests, HRV analysis, arterial stiffness assessments, hemodynamic monitoring, and microcirculatory function tests. Results: Athletes post COVID-19 showed significantly higher lean mass (p = 0.007), forced vital capacity (p = 0.001), and forced expiratory volume in 1 s (p = 0.007) than controls. HRV parameters did not significantly differ between the groups. Post-COVID-19 athletes exhibited peripheral vascular resistance (p = 0.048) and reflection index (p = 0.038). No significant differences were observed in the blood pressure, cardiac output, oxygen saturation, or microcirculatory oxygen absorption. Conclusions: Elite male athletes showed notable cardiovascular resilience after COVID-19, with only minor differences in vascular function. The maintained cardiac autonomic function and improved lung parameters in post-COVID-19 athletes suggests an adaptive response. These findings support the cardiovascular health of elite athletes following COVID-19 but emphasize the importance of continued monitoring.

Inflammation and cognitive performance in elite athletes: A cross-sectional study

Functional cognition is relevant for athletic success and interdependent with physical exercise, yet despite repeatedly demonstrated inflammatory responses to physical training, there are no studies addressing the relationship between cognition and inflammation in athletes. The aim of this study was to investigate the relationship between cognitive performance and selected inflammatory, and further physiological biomarkers in elite athletes. Data from 350 elite athletes regarding cognitive performance (processing speed, selective attention, working memory, cognitive flexibility), systemic inflammatory markers, metabolic hormones, growth factors, tissue damage markers, and micronutrients (e.g., ferritin, 25-OH-vitamin D), as well as physiological, subjective ratings of recovery and stress were analysed by correlative and multiple regression analyses. Results show that across all athletes variance in processing speed, selective attention, and working memory, could be best explained through a combination of metabolic hormones with physiological and psychological indicators of stress, and in cognitive flexibility through vitamin D levels. Only for the subgroup of athletes from closed-skill sports, the ratio TNF-α:IL-10 significantly contributed to explanation of variance in working memory and cognitive flexibility. In general, found correlations point to the importance of inflammatory balance and sufficient long-term nutrient supply for unaffected cognitive performance.
