Many elite athletes find the loss of their athletic abilities due to age or injury to be a profoundly challenging experience. While talent development is a well-studied phenomenon, far less attention has been paid to the issue of talent loss. We address this gap by exploring the experience and challenges faced by elite athletes who are losing, or who have lost, their talent. Drawing on three different understandings of the nature of talent, we argue that the experience of talent loss is constituted by three distinct yet interrelated forms of disorientation. We conclude by examining how athletes and those supporting them may respond to these challenges. [ABSTRACT FROM AUTHOR]

Objective: To determine the disparities in length of live and age-specific probabilities of death of US Olympians by sex, performance level, and age at debut at the Olympics. Methods: We apply parametric models of mortality to estimate probabilities of death by age. The best performing model (Gompertz model) is then used to calculate life tables for subpopulations of Olympians. The life table functions are then used to decompose the differences in life expectancies by age. Results: Olympians live longer than the general population but are a diverse population in terms of survival. Gender gap in survival is substantially smaller in Olympians than in general population. Medalists have a shorter lifespan than nonmedalists. Olympians debuting at extremely young ages (<22) have a survival disadvantage compared with Olympians debuting at older ages. The differences between general population and Olympians are widening in younger cohorts. Conclusion: US Olympians outlive the general population, but they constitute diverse group in terms of survival by sex, age at debut, and performance level. Studying and monitoring health disparities within the Olympic population is crucial for informing policies and regulations in sports organizations. [ABSTRACT FROM AUTHOR]

Research has shown that elite athletes frequently experience both insufficient and poor-quality sleep. In the present study, we examined the effectiveness of a sleep optimization intervention comprised of mindfulness and sleep hygiene on insomnia severity, symptoms of anxiety, stress, and emotion dysregulation among football players with sleep complaints. Sixty male football players with sleep complaints (mean age = 29.31, SD = 3.8) were randomly assigned to the active control condition (wellness program) or the sleep optimization intervention program (mindfulness plus sleep hygiene). All participants filled out questionnaires on insomnia severity, anxiety, perceived stress, and emotion dysregulation. Three data assessments were made: one at the start of the intervention (baseline), one at the end of the intervention 8 weeks later (posttest), and one 4 weeks after the posttest (follow-up). The severity of insomnia, anxiety, stress, and emotion dysregulation decreased over time in the sleep optimization group from baseline to posttest and at the follow-up. According to the present results, a sleep optimization intervention reduced insomnia, anxiety, stress symptoms, and emotion dysregulation in football players with sleep complaints.

Purpose: Pacing is crucial in endurance sports such as running, and its importance is also prominent in trail running due to the unique challenges, including high elevation gains and varied terrain. This study aimed to explore the pacing strategies of elite athletes during the 2023 World Mountain and Trail Running Championships for the Trail Short distance. Methods: The participants included 12 elite trail runners who provided their race data from sport watches for analysis. Results: The findings indicate a significant decrease in grade-adjusted pace (vi) as the race progressed, with an average change of −18.7% from the start to the last downhill segment. A linear correlation of −.55 (P =.031) was observed between the winning time and the evolution of vi, suggesting that more consistent pacing led to better performance. The Student t test (t = 2.628, numerator degrees of freedom = 10, P =.013) confirmed that even pacing is significantly correlated with superior race results at a confidence level above 95%. Conclusions: A more even pacing strategy is associated with success during elite trail-running races. [ABSTRACT FROM AUTHOR]

Purpose: Although women's futsal has experienced great growth recently, few studies have analyzed the physical profiles of female futsal players. The objectives of this study were to determine the physical and anthropometric characteristics in elite women's futsal using laboratory and field tests and to analyze the differences between the different playing positions. Methods: Forty-one female futsal players from the second division of the Spanish league (age 22.69 [4.76] y; body height 161.28 [6.03] cm; body mass 62.20 [10.34] kg) were evaluated for body composition with dual-energy X-ray absortiometry anthropometrically, lower-body power using a force platform (countermovement jump, squat jump, and drop jump), linear speed (5, 10, 15, and 25 m), changes of direction (505 modified, V-Cut, and L-Run), and repeated-sprint ability measured through photoelectric cells. Results: The results reveal that there are no significant differences between the physical profiles of players depending on playing position. Despite this, wingers seem to have the best physical profiles, and goalkeepers have the highest body mass index (26.9 [4.48] vs 23.3 [2.82]; P =.069) and fat percentage (31.9 [7.81] vs 29.96 [6.08]; P =.101), but they present very similar values to the other positions in all other tests performed, except for repeated-sprint ability (4.64 [0.45]; P =.009). Conclusion: Relevant descriptive data were presented to provide useful information for coaches to optimize their training programs, reporting that playing position does not identify different physical profiles in elite female futsal players.

Purpose: We tested the differences in maximum strength and various parameters of sprint performance between youth backs and forwards. Additionally, we examined the associations among various strength-sprint measures, as well as between unresisted and heavy resisted sprints. Methods: Thirty-two youth rugby players were assessed at the beginning of the season with the following tests: unresisted and resisted (50% body mass) 30-m sprints and 1-repetition maximum (1RM) in the squat exercise. Body mass, sprint velocity, and 1RM values were compared between backs and forwards using an independent t test. Pearson product–moment correlation was used to assess the relationships between absolute and relative 1RM values (rel1RM) and unresisted and resisted sprints. Results: Youth backs outperform forwards in terms of maximum velocity and under resisted sprinting conditions. Furthermore, backs exhibit higher levels of rel1RM compared with forwards. Our findings indicate significant correlations between resisted and unresisted sprinting for several sprint qualities when considering all players together. When participants were divided into different groups, stronger correlations between resisted and unresisted sprints were found among slower/heavier players (forwards). Notably, for faster players (backs), there was no significant correlation between heavy resisted sprints and maximum velocity (r =.25; P =.4). Last, despite their lower rel1RM values compared with backs, for forwards the rel1RM is closely associated with unresisted and resisted sprints. Conclusion: Unlike youth forwards, for youth backs, the ability to sprint faster with heavy sled loads is not associated with the maximum velocity achieved in linear sprints, and higher values of rel1RM do not necessarily lead to improved sprint performance.

Introduction: Women have generally lower body size and lean- to fat-mass ratio, lower maximal anaerobic power due to a lower muscle mass, and fewer fast-twitch fibers, although they can show higher resistance to fatigue or greater metabolic flexibility than men. These factors are well known and explain the sex differences in endurance sports such as distance running (10%–12%). Several of these factors—particularly the differences in body composition and skeletal-muscle characteristics—may directly impact vertical displacement and uphill performance. However, there is a lack of sex-difference reports in sports with uphill locomotion. Methods: The sex differences in world-level endurance performance over 10 years (2013–2022) in 6 different sports with uphill displacement (speed climbing, vertical race in ski mountaineering, vertical kilometer in mountain running, cycling, cross-country skiing, and ultratrail running) were calculated. Results: The sex differences are generally larger (18%–22%) than in endurance sports performed primarily on flat terrains. This may be due to the lower lean- to fat-mass ratio commonly reported in women. In shorter uphill events (eg, sport climbing, vertical kilometer, and short climb in cycling), the sex differences appear even more pronounced (28%–35%), potentially being explained by additional factors (eg, anaerobic capacity, muscle composition, and upper-body contribution). Conclusion: This novel analysis over 10 years of elite endurance performance in different sports with uphill displacement shows that the sex differences are generally larger (18%–22%) than in endurance sports performed primarily on flat terrains.

This study adopts the athletic career transition model to explore the experiences of Korean dual-career (DC) judokas during their junior-to-senior transition using a longitudinal approach. We recruited 12 Korean elite judokas, all of whom were in their first year of university during their initial interview. Participants were organized into three focus groups, with three rounds of interviews conducted over approximately 2 years, totaling nine focus-group sessions. Thematic analysis was applied, which led to the identification of three key themes: (a) multifaceted challenges, (b) coping strategies, and (c) perceived needs of DC athletes prioritizing sport over study. The results indicate that Korean DC judokas share some common challenges (e.g., increased training demands, balancing their studies with training demands) with their European counterparts, but they also face unique challenges (e.g., managing weight control, laundry duties, and relationships with senior judokas) specific to the Korean judokas. Their coping strategies include both internal resources (e.g., focusing on performance target, utilizing resilience) and external ones (e.g., seeking social support), emphasizing the critical role of psychological support during their junior-to-senior transition. Proactive psychological support is recommended through a specialized system tailored to this group. Given that Korean DC judokas significantly prioritize sport over education, this system should also address balancing both sport and education. [ABSTRACT FROM AUTHOR]

Purpose: To gather information on practices and perceptions of high-performance experts regarding their athletes' muscle fiber-type composition (MFTC) and its estimation. Methods: A questionnaire on the noninvasive versus invasive estimation of MFTC was completed by 446 experts including coaches and sport-science/sports-medicine staff. Moreover, the perceived importance of MFTC for training and performance optimization was assessed. Differences between sport types (individual and team sports) were analyzed using chi-square tests. Results: Forty percent of the experts implemented MFTC assessment in pursuit of performance optimization, while 50% did not know their athletes' MFTC but expressed a desire to implement it if they would be able to assess MFTC. Ten percent did not perceive value in MFTC assessment. Only 18% of experts believed that their athletes would undergo a muscle biopsy, leading to the adoption of alternative noninvasive techniques. Experts primarily relied on their experience to estimate MFTC (65%), with experts working in individual sports using their experience more frequently than those working in team sports (68% vs 51%; P =.009). Jump tests emerged as the second-most commonly employed method for estimating MFTC (56%). When only considering experts who are currently using MFTC, 87% use MFTC to individualize training volume and 84% to individualize training intensity. Conclusions: Experts value MFTC assessment primarily to individualize training but mainly rely on noninvasive methods to estimate MFTC. Some of these methods lack scientific validity, suggesting a continuing need for education and further research in this area. [ABSTRACT FROM AUTHOR]

Which opponent player to sequentially serve to in beach volleyball is crucial given the advantage of the attacking team. The sequential choice theory was tested in three studies by analyzing allocation strategies based on the hot hand belief. Study 1 showed strong belief in the hot hand of national coaches. In Study 2, we analyzed Tokyo Olympics data to explore how base rates and sequential selection rates varied in an elite sample. When base rates of players differed by 0.25, low-performing players were frequently selected. In an experiment with elite athletes, Study 3A demonstrated accurate base-rate-difference recognition but low base-rate-change recognition. Study 3B found that the hot hand is believed to be important but is not often detected. We conclude that players and coaches follow predictions of the sequential choice theory and believe in the hot hand, but do not have a shared understanding of how to use it. [ABSTRACT FROM AUTHOR]

Purpose: Travel fatigue impacts cognitive and physiologic systems, but its association with elite soccer match performance is unclear. In this retrospective observational study, we aimed to explore the association between travel and match outcomes in elite North American soccer. Methods: Travel data and match outcomes (team points or goals scored and conceded) and physical performance outcomes from 26 elite professional soccer teams and their players were analyzed (148 matches [team-based data] and 1252 player matches from 297 players; age 22.7 [4.5] y). Player- and match-level correlations between performance measures and both acute and cumulated travel metrics were analyzed. Results: Cumulative travel metrics were positively associated with team (travel distance [r =.20; 95% CI,.03–.25], travel time [r =.20;.06–.37], and time away [r =.20;.06–.37]) and individual player (travel distance, [r =.14;.08–.19], travel time [r =.17–.23], and time away [r =.13;.07–.18]) high-intensity running. Cumulative time away was negatively associated with team points (r = −.14; −.28 to −.001) and positively associated with goals conceded (r =.14;.01–.27); no clear association between acute travel metrics and match outcomes or physical performance was observed. Conclusions: As travel cumulated, away teams and their players ran more but for less reward (team points), although the magnitude of these associations was small. These data are exploratory and do not imply a causal relationship; however, further research should consider cumulation of travel. [ABSTRACT FROM AUTHOR]

The aim of the current study was to explore elite athletes' experiences of the COVID-19 pandemic and its impact on both growth and well-being. Informed by two complementary theoretical models, this research focused on elite athletes' potential to experience growth. Five elite athletes completed the Stress-Related Growth Scale–Revised and underwent semistructured interviews to develop a narrative of their experiences. Through a thematic analysis, we articulated elite athletes' experiences of both illusory and real adversarial growth following the COVID-19 pandemic. Four themes illustrated their experiences: the COVID-19 experience, searching for positives, self-transformation, and the social impact. A fifth theme, well-being, was integral throughout, involving the continued protection and development of athlete well-being. Future research recommendations and implications include further exploration of adversarial growth experiences after the pandemic and long-term effects of the pandemic on elite athletes, the creation of an adversarial growth measure, and engagement with this research to inform support measures to decrease the impact of adversity on elite athletes' well-being.

Purpose: To quantify the change in session rating of perceived exertion training impulse (RPE-TRIMP) that may occur in response to increased running distance at 3 running velocity ranges in elite sprinters. Methods: We monitored training load in elite sprinters (women: n = 7; men: n = 11) using wearable Global Positioning System technology and RPE-TRIMP for a total of 681 individual training sessions during a 22-week competition-preparation period. Internal training load was operationalized by RPE-TRIMP, and external training load was operationalized by distance covered in 3 velocity ranges. A linear mixed-effects model with athlete as a random effect was fit to RPE-TRIMP with total distance covered at ≤69.99% (low-velocity running [LVR]), 70% to 84.99% (high-velocity running [HVR]), and 85% to 100% (very-high-velocity running [VHVR]) of individual maximum velocity. Results: Increased running distance in all 3 velocity ranges (LVR, HVR, and VHVR) resulted in a significant (P <.001) increase in RPE-TRIMP. Coefficients (95% CIs) were.10 (.08–.11) for LVR,.23 (.18–.28) for HVR, and.44 (.35–.53) for VHVR. A 50-m increase in running distance covered in the LVR, HVR, and VHVR velocity ranges was associated with increases in RPE-TRIMP of 5, 11.5, and 22 arbitrary units, respectively. Conclusions: Internal training load, calculated as RPE-TRIMP, increased with increases in total distance covered in the LVR, HVR, and VHVR velocity ranges (P <.001). RPE-TRIMP can be a practical solution for monitoring global training-session load in elite sprinters. [ABSTRACT FROM AUTHOR]

Objective: To (1) establish extensive physiological profiles of highly trained CrossFit® athletes using gold-standard tests and (2) investigate which physiological markers best correlate with CrossFit Open performance. Methods: This study encompassed 60 participants (30 men and 30 women), all within the top 5% of the CrossFit Open, including 7 CrossFit semifinalists and 3 CrossFit Games finalists. Isokinetic dynamometers were employed to measure maximum isometric and isokinetic leg and trunk strength. Countermovement-jump height and maximum isometric midthigh-pull strength were assessed on a force plate. Peak oxygen uptake (VO2peak) was measured by a cardiopulmonary exercise test, and critical power and W′ were evaluated during a 3-minute all-out test, both on a cycle ergometer. Results: Male and female athletes' median (interquartile range) VO2peak was 4.64 (4.43, 4.80) and 3.21 (3.10, 3.29) L·min−1, critical power 314.5 (285.9, 343.6) and 221.3 (200.9, 238.9) W, and midthigh pull 3158 (2690, 3462) and 2035 (1728, 2347) N. Linear-regression analysis showed strong evidence for associations between different anthropometric variables and CrossFit Open performance in men and women, whereas for markers of cardiorespiratory fitness such as VO2peak, this was only true for women but not men. Conventional laboratory evaluations of strength, however, manifested minimal evidence for associations with CrossFit Open performance across both sexes. Conclusions: This study provides the first detailed insights into the physiology of high-performing CrossFit athletes and informs training optimization. Furthermore, the results emphasize the advantage of athletes with shorter limbs and suggest potential modifications to CrossFit Open workout designs to level the playing field for athletes across different anthropometric characteristics.

Purpose: Postactivation performance enhancement (PAPE), which refers to the phenomena associated with the attainment of enhanced performance in sport-specific tasks after a conditioning activity, is an important objective of warming-up practices in many sports. This is even more relevant for sprinters, as potential increases in sprinting speed will directly influence their competitive results. This systematic review with meta-analysis evaluated the effects of different PAPE protocols (ie, using plyometrics, strength-power exercises, and resisted/assisted sprints) on the sprinting performance (ie, sprint time or sprint speed) of competitive sprinters. Methods: Initially, 1205 records published until last December 18 were identified, using the following databases: PubMed/MEDLINE, Scopus, and Clarivate Web of Science. After removing duplicates and screening titles and abstracts, 14 high-quality studies met the inclusion criteria for the meta-analysis. Results: Overall, there were no significant changes in sprint performance after implementing various types of conditioning activities (standardized mean difference [SMD] = 0.16 [95% CI, −0.02 to 0.33]; Z = 1.78; P =.08; I2 = 0%). In addition, when comparing prechanges and postchanges between experimental, control, and other conditions, no significant differences were found in sprint speed or time across all studies (SMD = 0.09 [95% CI, −0.10 to 0.28]; Z = 0.92; P =.36; I = 0%). Conclusions: Results revealed that different types of conditioning activities may not be capable of acutely enhancing the sprint speed of competitive sprinters. This aligns with previous observations indicating that sprinting is a highly stable physical capacity, a phenomenon that is even more consistent among elite sprinters. Coaches and sport scientists should collaborate to develop more efficient PAPE protocols for these highly specialized athletes, with special attention to study design and individualization, while considering their effects on acceleration versus top speed.

Purpose: To examine nocturnal sleep patterns, napping behaviors, and subjective wellness responses of elite water polo players within an in-season week and to identify whether sleeping patterns differ between men and women. Methods: Sleep characteristics of 10 male and 17 female professional water polo players were objectively assessed during 1 week of the in-season period, including 5 training days, 1 match day, and 1 day of rest. Internal load (rating of perceived exertion × duration of training or match) was assessed 30 minutes posttraining or postmatch, and the total quality of recovery was recorded every morning. A series of multilevel models were used to analyze the data. Results: Time in bed and wake-up time were earlier on both training (P <.001) and rest days (P <.001) than on the day of the match. Internal workload did not predict any of the players' sleeping patterns. Midday naps predicted less time in bed (P =.03) and likely less sleep time (P =.08). The total quality of recovery was predicted only by the total sleep time (P <.01). Women exhibited higher sleep efficiency (P <.001), less waking after sleep onset (P =.01), and a lower number of awakenings (P =.02) than men. Conclusions: The current results indicate that the nocturnal sleep patterns of elite water polo players are not associated with internal load and that women display better nocturnal sleep quality compared with men. As long naps interfere with nocturnal sleep, and total nocturnal sleep time predicts total quality of recovery, we suggest that athletes follow hygiene sleep strategies to facilitate adequate nocturnal sleep and next-day recovery.

Purpose: Injury prevention is a crucial aspect of sports, particularly in high-performance settings such as elite female football. This study aimed to develop an injury prediction model that incorporates clinical, Global-Positioning-System (GPS), and multiomics (genomics and metabolomics) data to better understand the factors associated with injury in elite female football players. Methods: We designed a prospective cohort study over 2 seasons (2019–20 and 2021–22) of noncontact injuries in 24 elite female players in the Spanish Premiership competition. We used GPS data to determine external workload, genomic data to capture genetic susceptibility, and metabolomic data to measure internal workload. Results: Forty noncontact injuries were recorded, the most frequent of which were muscle (63%) and ligament (20%) injuries. The baseline risk model included fat mass and the random effect of the player. Six genetic polymorphisms located at the DCN, ADAMTS5, ESRRB, VEGFA, and MMP1 genes were associated with injuries after adjusting for player load (P <.05). The genetic score created with these 6 variants determined groups of players with different profile risks (P = 3.1 × 10−4). Three metabolites (alanine, serotonin, and 5-hydroxy-tryptophan) correlated with injuries. The model comprising baseline variables, genetic score, and player load showed the best prediction capacity (C-index:.74). Conclusions: Our model could allow efficient, personalized interventions based on an athlete's vulnerability. However, we emphasize the necessity for further research in female athletes with an emphasis on validation studies involving other teams and individuals. By expanding the scope of our research and incorporating diverse populations, we can bolster the generalizability and robustness of our proposed model. [ABSTRACT FROM AUTHOR]

Purpose: Successful participation in taekwondo (TKD) requires athletes to possess quick decision-making abilities and demonstrate technical proficiency during competition. Dehydration, occurring during both training and competition, is widely recognized to have various negative effects. Methods: This study investigated the impact of different levels of dehydration on cognitive function, as measured by the Vienna Test System, and the specific performance of kicking techniques among TKD athletes. Using a randomized crossover design, 12 participants were involved in the study. Before and after 1 hour of training at 80% of maximal heart rate, participants were weighed and provided urine samples. All participants were randomly assigned to 3 different hydration conditions: the euhydrated (EUH) group had unrestricted access to fluid consumption, while the hypohydrated (HYP) and severely HYP (S-HYP) groups experienced reductions of 2.0% and 4.0% of their initial body weight, respectively. Results: The EUH group exhibited better reaction speed in reaction-time test-form S1 than the HYP and S-HYP groups. Notably, the EUH group demonstrated a significantly higher success rate in the front-side kick (EUH 98%, HYP 90%, S-HYP 88%; P <.05). However, the success rates of back roundhouse kick and free head kick were similar among the 3 statuses. Furthermore, postexercise heart rates were found to be significantly higher in the HYP and S-HYP groups compared with the EUH group. Conclusions: This study provides insight into the negative effects of dehydration on cognitive function and TKD-specific performance. It is recommended that TKD athletes maintain optimal hydration levels during training and competition to ensure optimal performance. [ABSTRACT FROM AUTHOR]

Much of the current research on sprint start has attempted to analyze the biomechanical characteristics of elite athletes to provide guidance on the training of sprint technique, with less attention paid to the effects of motor experience gained from long-term training on neuromuscular control characteristics. The present study attempted to investigate the effect of motor experience on the modular organization of the neuromuscular system during starting, based on he clarification of the characteristics of muscle synergies during starting. It was found that exercise experience did not promote an increase in the number of synergies but rather a more focused timing of the activation of each synergy, allowing athletes to quickly complete the postural transition from crouching to running during the starting.

This study explored goal-directed self-talk and its optimization through educational self-talk interventions, focusing on a novel sports-oriented board-game intervention. Examining a practitioner's experiences and diverse participant profiles, including an elite tennis player, a recreational athlete, a football referee, and a tennis coach, the research employed four in-depth case studies. A unique aspect of this study involved intentional control transfer from practitioner to client, documented through a practitioner diary and postintervention interviews. Participants generally expressed appreciation for the intervention; however, the coach's case necessitated bespoke adjustments, underscoring the importance of contextual sensitivity in applied practice. The educational self-talk intervention reportedly facilitated the analytical deconstruction of challenges, enhancing self-regulation through goal-directed self-talk. The study underscored the pedagogical merit of the board game and observed a substantive transfer of control from practitioner to participant over the intervention's longitudinal trajectory. Detailed recommendations have been crafted for practitioners to implement the educational self-talk intervention effectively in their practice. [ABSTRACT FROM AUTHOR]

Despite a growing interest in emotions in sport psychology, little has been written about the contextual elements triggering athletes' emotional experience. This single case study aimed to analyze the inducers of an elite table tennis player's emotional experience throughout his career. He was ranked among the 15 best players in the world, and his career spanned more than 20 years. Inspired by the critical-incident method, we conducted a lengthy interview with the player, during which he related the most significant moments of his career. The categorization of the 96 critical incidents collected highlighted four inducers of positive emotions and five inducers of negative emotions, emerging over five periods (exponential progression, first difficulties, major difficulties, second career, and end of career). These findings contribute to the development of an innovative single-case-study design, allowing an understanding of the contextual origin of athletes' emotions over the long term. Finally, highlights are discussed and recommendations for the practice of sport psychology are formulated. [ABSTRACT FROM AUTHOR]

Mindfulness-based interventions have gained popularity among elite athletes, but their effectiveness in enhancing archery performance has been inconsistent. This study examined the feasibility of a 12-week mindfulness flow program (MFP) specifically designed for the archers and assessed the effect of the MFP on shooting performance. Twelve members of the Hong Kong Archery Team voluntarily participated in the present study. Their shooting performance, anxiety, mindfulness, and flow state were assessed before and after the MFP intervention. The results showed that the MFP was highly feasible, with 100% attendance. The athletes highly enjoyed the MFP sessions (mean rating: 7.9/10). Improved shooting performance, increased mindfulness, and flow state levels, and reduced anxiety were also observed after the intervention. These findings suggest a positive reception from and potential benefits for athletes. However, it is suggested to conduct additional research using randomized controlled trials to explore the program's effects and applicability in enhancing sports performance. [ABSTRACT FROM AUTHOR]

Limited research into professional rugby union players' experiences of seeking formal support for their mental health exists, despite comparable rates of mental health issues among elite rugby players with the general population. This qualitative study explored professional players' actual experiences of accessing Rugby Players Ireland's mental well-being service, via separate focus group discussions with professional players (n = 5) and player development managers (n = 4) who refer players into the service. An inductive reflexive thematic analysis identified three themes detailing players' (a) journey to disclosure of their mental health difficulties, (b) their expectations and engagement with the well-being service, and (c) participants' reflections on mental health experiences in a high-performance environment. Embedding mental health as a key component of player development in high-performance environments, improving mental health literacy, normalizing mental health experiences, and encouraging help-seeking would help promote player well-being and support holistic development alongside sporting performance.

This study analyzed media framing of athletes who have suffered mental ill health. The mass media play a crucial role in shaping public attitudes and perceptions surrounding mental health, and the present study aimed to examine the media reporting of athletes' mental ill health and to further explore how this reporting has changed over time. We examined the reporting of elite athletes in three U.K. media outlets between January 2000 and December 2019, identifying 75 athletes from 26 different sports. From analysis, four themes were developed to consider the content of media reporting and how it has changed over three time phases. The analysis revealed that media reporting of mental ill health has increased over time, and changes were observed in terms of the specific terminology used, with greater depth in the articles, such as journalists speaking to other professionals to construct the articles. This study contributes toward our growing understanding of the reporting of mental ill health by providing empirical evidence of the increased attention to the topic and increasingly responsible reporting in the media.

This case study focuses on how Norwegian ski jumpers performed in the Beijing 2022 Winter Olympics and the following FIS (International Ski and Snowboard Federation) ski flying World Championships 2022 in Vikersund, Norway, despite organizational conflict at the management level and intense and sustained media coverage the entire season. Five athletes (one third of the elite squad) were interviewed about how they coped with the stressors. The results revealed two main responses: One group avoided, as far as possible, hearing or reading about the conflicts and tried to stay in their "bubble" and focus on preparing for competition. The other group chose to follow the conflicts and was more willing to interact with the media, therefore experienced a higher degree of perceived stress, and consequently needed to employ a wider range of coping strategies. The findings highlight the importance of a consistent and effective management strategy in helping athletes to focus on training and competition preparation and insulate them from stressors generated by organizational turbulence and conflicts.

Understanding the daily energy expenditure of athletes during training is important to support recovery, adaptation, and the maintenance of performance. The aim of the current research was to assess the total daily energy expenditure (TDEE) and the acute energy expenditure (EE) of tennis training sessions during habitual training of elite tennis players. Using a cohort study design, 27 (n = 10, male; age; 22.3 ± 3.2 years and n = 17, female; age: 23.8 ± 3.5 years) elite singles tennis players were assessed for TDEE and tennis training EE. Using Actiheart activity monitors during a 2- to 5-day training period, male players were analyzed for 26 days and 33 (1.3 ± 0.5 sessions/day) tennis training sessions, and female players for 43 days and 58 (1.2 ± 0.4 sessions/day) tennis training sessions. Male TDEE (4,708 ± 583 kcal/day) was significantly higher than female (3,639 ± 305 kcal/day). Male absolute and relative tennis training EEs (10.2 ± 2.3 kcal/min and 7.9 ± 1.4 kcal·hr−1·kg−1) were significantly higher than those of females (7.6 ± 1.0 kcal/min and 6.8 ± 0.9 kcal·hr−1·kg−1). The resting metabolic rate was assessed via indirect calorimetry. The physical activity level for both groups was 2.3 AU. The TDEE of male and female players during habitual training now highlights the continual cycle of high energy demands experienced by the elite tennis player. The broad ranges of TDEE and EE reported here suggest individual assessment and nutritional planning be prioritized, with a particular focus on carbohydrate requirements. [ABSTRACT FROM AUTHOR]

Purpose: This 2-year longitudinal study examined the development of upper-extremity bone mineral density (BMD), bone mineral content (BMC), and lean mass (LM) asymmetry magnitudes in male and female youth tennis players. Methods: Dominant and nondominant upper-extremity BMD, BMC, and LM values of 49 male and 31 female players were measured yearly using dual X-ray absorptiometry. From these values, asymmetry magnitudes were calculated and expressed as a percentage. Maturity offset was estimated using anthropometric measurements. Linear mixed effect models examined the development of BMD, BMC, and LM asymmetry magnitudes according to players' maturity offset, sex, and training volume. Results: Adjusted for sex and training volume, a 1-year increment in maturity offset was associated with a significant increase in BMD (1.3% [2.2%]; P <.001) and BMC (0.6% [2.4%]; P =.011) asymmetry magnitudes. Male players displayed significantly higher LM asymmetry magnitudes (Δ3.2% [8.4%]; P =.002) compared with their female counterparts. Training volume was not significantly associated with asymmetry magnitude development. Conclusion: In contrast to LM, male and female youth tennis players' upper-extremity bones are still responsive to mechanical loading with a significant increase in BMD and BMC asymmetry magnitudes according to maturity offset.

Adequate sleep is crucial for elite athletes' recovery, performance readiness, and immune response. Establishing reference ranges for elite athletes enables appropriate contextualization for designing and targeting sleep interventions. Purpose: To establish sleep-quality reference ranges for Olympic and Paralympic cohorts using the Pittsburgh Sleep Quality Index (PSQI) and explore differences based on sex and sport types. Methods: Team USA athletes (men = 805, women = 798) completed the PSQI as part of a health-history questionnaire. Descriptive statistics were used to create reference ranges and linear models, and χ2 test of independence determined differences in PSQI global and component scores between sex, games, season, and participation. Results: Six hundred thirty-two (39.43%) athletes reported poor sleep (PSQIGlobal ≥ 5). Men displayed later bedtimes (P =.006), better global PSQI scores, shorter sleep latency, less sleep disturbance, and less use of sleep medication than women (all P <.001). Winter Games participants had later bedtime (P =.036) and sleep offset time (P =.028) compared with Summer Games athletes. Team-sport athletes woke earlier than individual-sport athletes (P <.001). Individual-sport athletes were more likely to have low (P =.005) and mild (P =.045) risk for reduced sleep duration than team-sport athletes. Conclusion: These data provide PSQI-specific reference ranges to identify groups at greatest risk for poor sleep, who may benefit most from targeted sleep interventions. [ABSTRACT FROM AUTHOR]

The present study explored how three professional Australian football coaches learned and understood mental toughness. Participants shared stories regarding mental toughness through semistructured interviews. Reflexive thematic analysis was used to interpret the data. Creative nonfiction was employed to develop a composite story. All participants' voices contributed equally to the narrative, which follows Sam (our composite coach) through three periods in his career: as a junior player, an elite footballer, and, finally, a coach in the professional football environment. Mental toughness was fundamentally determined by the sociocultural environment in which one was immersed. Athletes and coaches were expected to internalize dominant understandings of mental toughness and reinforce ideals and were punished if they deviated from mentally tough standards set up in their clubs. Mental toughness was defined by various values, beliefs, and norms that originated from the sociocultural environment, indicating the importance of context in understanding the roots of being mentally tough.

The aim of the present study was to identify profiles of elite athlete mental well- and ill-being and study how the profiles (i.e., subgroups of athletes) differed in sport-related demands and resources. A total of 259 Finnish elite athletes (n = 170 active and n = 89 retired) completed quantitative self-report inventories. Through cluster analysis, four profiles of mental well- and ill-being were identified. Profile 1 was overrepresented by retired, older, and male athletes, and characterized by good mental well-being. Profile 2 consisted mainly of active athletes who reported mild risk for alcohol abuse. Profile 3 consisted mainly of women who displayed possible presence of an eating disorder. Profile 4 was typical of young athletes with mental ill-being. The balance between sport-related demands and resources appeared to be the healthiest in Profile 1 and worst in Profile 4. The present findings are beneficial for those who work with and/or provide psychological support to athletes. [ABSTRACT FROM AUTHOR]

While research advancements have substantially improved concussion management efforts, consideration for the psychological and social aspects of concussive injuries have remained largely absent from concussion protocols. The present study was undertaken to identify elite athletes' psychological and social needs during the recovery process. Elite athletes with a history of concussion and mental performance consultants who work with concussed elite athletes participated in focus group interviews to shed light on these needs. A thematic analysis of these focus groups revealed six psychological and social needs: acceptance, normality, confidence, self-efficacy, trust in relationships, and social support. These themes are framed within concussion literature to help initiate a conversation on how psychological and social needs should be addressed as part of multifaceted efforts to improve concussion recovery.

This cross-sectional study explored athlete responses to the Compassion Motivation and Action Scales Self-Compassion Scale, examining its relationship with well-being. Athlete (N = 207; mean age 27.9 years) scores were consistent with previous population means. Scores on the Compassion Motivation and Action Scales Self-Compassion Scale did not differ between elite and nonelite athletes, nor did they correlate significantly with trait competitiveness. Significant differences emerged based on athlete well-being state, with athletes categorized as "flourishing" scoring higher on the total score and all subscales of the Compassion Motivation and Action Scales Self-Compassion Scale, as compared with those with "moderate mental health" (Cohen's ds from 0.58 to 0.92). Furthermore, the distress tolerance subscale significantly mediated the relationship between self-compassion intentions and well-being (indirect path: B = 0.034, p <.001). The results suggest that self-compassionate intentions are not enough, and athletes may need support to tolerate the distress that comes with moving toward one's own suffering.

Purpose: To investigate performance progression from early-junior to peak performance age and compare variety in race distances and swimming strokes between swimmers of various performance levels. Methods: Using a longitudinal data analysis and between-groups comparisons 306,165 annual best times of male swimmers (N = 3897) were used to establish a ranking based on annual best times at peak performance age. Individual performance trajectories were retrospectively analyzed to compare distance and stroke variety. Performances of world-class finalists and international- and national-class swimmers (swimming points: 886 [30], 793 [28], and 698 [28], respectively) were compared across 5 age groups—13–14, 15–16, 17–18, 19–20, and 21+ years—using a 2-way analysis of variance with repeated measures. Results: World-class finalists are not significantly faster than international-class swimmers up to the 17- to 18-year age group (F2|774 = 65, P <.001, η p 2 =.14) but specialize in short- or long-distance races at a younger age. World-class breaststroke finalists show faster breaststroke times compared to their performance in other swimming strokes from an early age (P <.05), while world-class freestyle and individual medley finalists show less significant differences to their performance in other swimming strokes. Conclusions: While federation officials should aim for late talent selection, that is, not before the 17- to 18-year age group, coaches should aim to identify swimmers' preferred race distances early on. However, the required stroke variety seems to be specific for each swimming stroke. Breaststroke swimmers could aim for early and strong specialization, while freestyle and individual medley swimmers could maintain large and very large stroke variety, respectively.

Purpose: A decline in youth running was observed at the start of the COVID-19 pandemic. We investigated whether the resumption of organized running after social distancing restrictions changed running habits or injury frequency in adolescent runners. Methods: Adolescents (age = 16.1 [2.1] y) who participated in long-distance running activities completed an online survey in the Spring and Fall of 2020. Participants self-reported average weekly running habits and whether they sustained an injury during the Fall 2020 season. Poisson regression models and 1-way analysis of variance compared running habits while Fisher exact test compared differences in frequencies of injuries during Fall 2020 among season statuses (full, delayed, and canceled). Results: All runners, regardless of season status, increased weekly distance during Fall 2020. Only runners with a full Fall 2020 season ran more times per week and more high-intensity runs per week compared with their Spring 2020 running habits. There were no differences in running volume or running-related injury frequency among Fall 2020 season statuses. Conclusions: There were no significant differences in running-related injury (RRI) frequency among runners, regardless of season status, following the resumption of cross-country. Health care providers may need to prepare for runners to increase running volume and intensity following the resumption of organized team activities. [ABSTRACT FROM AUTHOR]

Organizational culture in sports affects well-being, performance, and overall success. Although team culture has been explored within able-bodied teams, little is known about culture development within parasport. Using a descriptive case study approach, our study examined the culture development and experiences of an elite parasport team. Two semistructured individual telephone interviews were conducted with nine participants (athletes and staff), and one athlete-participant completed one interview. An inductive thematic analysis revealed two themes: approach to culture development and team culture components. Culture development was linked with facilitative leadership and important resources. This supported the team to create their shared values and mechanisms, including a behavioral framework, other artifacts (e.g., shared language and team motto), and a relaxed environment. These helped to maintain their agreed culture and benefited their well-being, progress, and team cohesion. Our results offer a starting point regarding research into the culture of elite parasport and have practical implications for managers, coaches, and psychologists. [ABSTRACT FROM AUTHOR]

Projecting authenticity is crucial for athletes engaged in personal branding. Prior scholarship has emphasized the "frontstage" of authenticity: what tactics athletes use to present themselves and how audiences perceive such tactics. But it has not yet examined the "backstage": why athletes pursue authenticity and the strategic considerations involved in such ongoing self-presentations. Using a constructivist grounded theory that draws on interviews with 30 elite athletes engaged in personal branding, we unpack these backstage processes, which are not straightforward but entail an ongoing cycle of authenticity negotiation. Our model of authenticity negotiation identifies conflicting authenticity demands and constraints imposed by various actors, which athletes attempt to resolve over time using a range of authenticity management tactics. By modeling the backstage processes in authenticity negotiation, our research integrates, contextualizes, and suggests extensions to the existing frontstage work on authenticity. It offers guidance to athletes and practitioners on managing athlete brands and stakeholder collaborations. [ABSTRACT FROM AUTHOR]

Clinical Scenario: Injuries that affect the groin region are among the most common in football players. To prevent this condition, studies have focused on strengthening the adductors, hip flexors, or abdominal muscles. Recent investigations have used an eccentric-biased exercise (Copenhagen Adduction Exercise [CAE]) that promotes functional and architectural adaptations in the muscle tissue, though its effect on injury risk reduction is unknown. Clinical Question: Can the Copenhagen Adduction Exercise prevent groin injuries in soccer players? Summary of Key Findings: The literature was searched for studies investigating the potential groin injury risk reduction effect of the CAE. (1) Three studies met the inclusion criteria and were used for this appraisal; (2) one study observed a significantly lower injury rate ratio favoring the group that used the CAE program; and (3) 2 studies found similar or higher injury rates in the intervention groups, not supporting the inclusion of the CAE as a preventative tool. Clinical Bottom Line: There is conflicting evidence that usage of the CAE is superior to not performing adductor strengthening exercises in mitigating the risk of sustaining groin injuries. Given the evidence supporting these findings, it is advisable to exercise caution when contemplating the incorporation of the CAE into training regimens aimed at preventing groin injuries. Strength of Recommendation: There is Grade B evidence to suggest that inclusion of the CAE may not be associated with reduced injury rates. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this systematic review is to evaluate the original peer-reviewed studies on athletes who developed myocarditis after coronavirus disease (COVID-19) infection or after COVID-19 mRNA vaccination. Both entities likely have an immunologic component. We discuss elite, professional, college, and adolescent athletes. The athletes are generally young and healthy, representing a distinctive population group that differs from the general population. This review includes diagnosis of myocarditis, incidence, complications, prognosis, and return-to-play guidance for sports medicine clinicians and coaches. Data Sources: We surveyed the PUBMED, Embase, and Web of Science databases for the relevant peer-reviewed articles in the English language published from the onset of the pandemic until April 2023. Included were original observational studies and case series. Excluded were individual case reports and a small series with incomplete data. The resulting search yielded 30 original articles. Main Results: Reported myocardial abnormalities in athletes were rare after COVID-19 infection and even less frequent after COVID-19 mRNA vaccination. True incidence, however, may be higher because of under-reporting and frequent asymptomatic presentation. Male gender was prevalent for both manifestations; postvaccination myocarditis occurrence was the highest after the second vaccine dose. Diagnostic and return-to-play algorithms were developed and should be adopted and followed. Conclusions: The risk of myocarditis from COVID-19 infection and COVID-19 mRNA vaccination is very low. The long-term prognosis and evolution of the observed cardiac magnetic resonance abnormalities are currently unknown. Although inferences can be made from the published data, COVID-19 and postvaccine myocarditis in athletes may represent only a small fraction of the true incidence of those who have been affected worldwide and not evaluated.

This systematic literature review aimed to map and synthesise the multidisciplinary research field of constraints and facilitators of elite athletes' dual careers. Trends and gaps in the literature to shape future research, policy, and management practice to initiate change were outlined. This review employed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses flowchart. Thereby, 126 relevant journal articles were identified, and their contents were evaluated. The results demonstrated an emerging and multidisciplinary body of literature with a geographical concentration on European studies. The findings indicated many constraints and facilitators at the intrapersonal, interpersonal, and structural levels. The results suggested that an athlete's situation and environment determine whether a factor is a constraint or a facilitator, as several overlaps were identified. Thematic, theoretical, methodological, and practical agendas were discussed. Propositions indicating avenues for future research were identified. This review contributes to knowledge as it not only looks at one athlete population (e.g. student-athletes) but integrates studies of types of elite athletes. Moreover, an equal emphasis was placed on evaluating the existing journal articles thematically, theoretically, methodologically, and practically. This is original concerning constraints and facilitators of elite athletes' dual careers. [ABSTRACT FROM AUTHOR]

The sporting career of elite athletes is a limited, inevitably terminal and often short career, with an early retirement process, so elite athletes should consider having a second professional career. In this sense, entrepreneurship is a popular choice for professional athletes and, moreover, they are considered to be well equipped, in terms of personality and skills, for this entrepreneurial career. The aim of this study is to analyse the influence of different entrepreneurial skills on the Entrepreneurial Intentions of elite athletes, also taking into account other factors such as whether they follow a Dual Career. In this way, the aim is to show how the entrepreneurial skills acquired and developed through high-level sport (resilience, proactivity and creativity) can influence the Entrepreneurial Intentions of these athletes, and help them to succeed in their professional career after retirement. The sample was composed by 200 elite athletes from Spain. Results showed that these athletes perceived a high degree of development of the skills. Besides, three solutions were obtained for high levels of Entrepreneurial Intentions that explained the 38% of these cases. The combinations of high levels of resilience with high levels of creativity were presented in all the solutions in combination with other variables, and proactivity, in a lesser extent, in two solutions. Finally, some theoretical and practical implications are proposed in order both to improve the research on the topic and highlight the importance of educational training of elite athletes to increase their possibilities to success in their future entrepreneurial career.

By utilizing the Contingent Valuation Method (CVM), this study aims to calculate the Korean citizens' willingness to pay (WTP) for elite athlete development and to determine whether a difference exists between the general public's WTP and the government's investment in the cause. The WTP per household was 15.82 USD. Multiplying the aforementioned figure by the number of households in Korea in 2020, we estimated that the total annual benefits of national athlete training support are 322.801million USD. After the survey on the WTP for the research participants, then adjusting for the income tax paid during 2021–2025 to the price level of 2019, the economic benefit of elite athlete development was calculated to be 1.354 billion USD for 30 years, and 86.869 million USD when converted to an annual basis. The 2019 national athletes training cost supported by the government, which is 61.652 million USD, was compared with the result of this study, 86.869 million USD. As a result, the benefits of training national representatives are estimated to be about 1.4 times higher than the national athletes training cost of sports supported by the government. This study makes significant contributions in that it is the first study in Korea to estimate the value of national athlete training support as a quantified basis based on quantitative analysis, unlike previous qualitative analysis of tentative policies.

Introduction: This study aimed to analyse the differences between pressure training and official competition matches in high-level male padel players from Finland, focusing on the proportion of points won by serving and returning players, the frequency of break points and golden points, and the effectiveness of the last shot. Methods: A total of 4,417 points from 38 matches played during the 2022 and 2023 seasons were analyzed. Results: The results revealed no significant association between match type (pressure training vs. competition) and the distribution of winners, forced errors, or unforced errors (p = 0.867). Similarly, the frequency of break points, non-break points, golden points, and non-golden points remained consistent across both match types, regardless of the service situation (serving or returning players). While a relationship was observed between shot type and match type in forced errors (p = 0.024), the overall shot effectiveness remained comparable across different shot types. Discussion: In conclusion, this study suggests that high-level male padel players display comparable technical-tactical performance in pressure training and official competition matches.
