International performance level in adult ice hockey: The role of the talent environment in youth.

Despite a growing interest in conducive talent development environments (TDE), the relationship between TDEs and the performance level in adulthood remains unclear. Therefore, this study examined the relationship of the micro-environment of former Swiss junior national team ice hockey players with their performance level in adulthood. With quantitative, retrospective data from n = 106 players born between 1984 and 1994, patterns of four factors club, family, peer, and school were built for early (13-15 years old) and late (16-19 years old) youth. The results revealed four structurally and mainly individually stable clusters for both developmental stages in youth. The cluster of the moderately above-average supported players between 16-19 years old demonstrated above-average values in all factors of the micro-environment and are more likely to reach international playing level in adulthood, whereas the structurally weak supported players are linked to a later regional playing level. These results indicate that simultaneous support across all four factors of the micro-environment in youth (club, family, peers, and school) is important to reach an international playing level, while low support in one or more area reduces the chance thereof. Thus, creating supportive environments across the board should be considered for a successful talent development.

Stability of context in sport and exercise across educational transitions in adolescence: hello work, goodbye sport club?

BACKGROUND: The present study firstly aimed to identify context patterns in sport and exercise among adolescents at lower and upper secondary education. The organisational, social and competitive contexts of leisure-time sport and exercise were included as pattern indicators. The second aim was to examine the stability of these patterns across educational transition. The last aim was to investigate whether a subjective evaluation of the transition influences whether people stay in the same pattern across time. METHODS: One-year longitudinal data of 392 adolescents were analysed. RESULTS: Both before and after the educational transition, four context patterns were identified: the traditional competitive club athletes with friends, the self-organised individualists, the non-club-organised sportspersons and the mostly inactives. More than half of the individuals stayed in the same pattern across time. When individuals changed pattern, their change was most often from the self-organised individualists and the non-club-organised to the mostly inactives. A subjective evaluation of the transition influenced the stability of only the traditional competitive club athletes with friends. The chance of these people staying in the same pattern decreased with increased transitional stress. CONCLUSIONS: Knowledge about the stability and change of context patterns can be used to make recommendations for policy strategies and to develop more individually-tailored promotion programs.

What do adolescents and young adults strive for in sport and exercise? An explorative study on goal profiles in sport and exercise.

In sport and exercise promotion, it is important to consider goals because achieving these goals leads to a sense of well-being and behaviour adherence. Individuals often pursue multiple goals simultaneously. Therefore, it is also important to not only consider each individual's combination of goals but also to identify so-called "goal profiles". Taking a developmental-psychological perspective, the goal profiles of adolescents may differ from those of young adults. Furthermore, goal profiles might differ concerning the self-determined motivation, sport and exercise behaviour, and gender. Therefore, both age groups, 966 adolescents and 636 young adults, were questioned by self-report on their goals in sport and exercise, self-determined motivation, sport and exercise behaviour, and gender. A multiple-group-analysis for latent-profile-solutions was conducted resulting in six goal profiles for both age groups. As expected, the shape of these profiles differed qualitatively for the majority of adolescents and young adults: In adolescents, goals such as contact and the perception of challenge were more prominent, whereas in young adults, health, figure/appearance, and distraction/catharsis were dominant. Validation analyses support the profiles identified as they differ in self-determined motivation, sport and exercise behaviour, and gender. To more efficiently tailor interventions, an age-specific focus on goal profiles seems promising.

Effectiveness of Individual Exercise and Sport Counseling Based on Motives and Goals: A Randomized Controlled Trial.

This study tested the effectiveness of individual exercise and sport counseling in a nonclinical setting. The COunseling based on Motives and goals in Exercise and sporT (COMET) approach focuses on individual motives and goals and aims to identify suitable activities. Participants experience different exercise and sport activities and reflect on them with a counselor, who applies motivational interviewing. A stratified randomized controlled design with 129 people was used. The intervention group took part in a counseling event, which included feedback on motives and goals, trial exercise and sport sessions, and structured reflection. Four weeks later, members of the group got a telephone booster. The control group received minimal intervention as written information. Results show that the counseling promoted motivational competence (η2 = .16), physical activity-specific self-control (η2 = .08), and the weekly volume of exercise and sport (η2 = .15), whereas it did not influence self-concordance. Further studies can investigate whether the COMET approach is also effective in other settings.

Maturity-based correction mechanism for talent identification: When is it needed, does it work, and does it help to better predict who will make it to the pros?

When identifying talent, the confounding influence of maturity status on motor performances is an acknowledged problem. To solve this problem, correction mechanisms have been proposed to transform maturity-biased test scores into maturity-unbiased ones. Whether or not such corrections also improve predictive validity remains unclear. To address this question, we calculated correlations between maturity indicators and motor performance variables among a sample of 121 fifteen-year-old elite youth football players in Switzerland. We corrected motor performance scores identified as maturity-biased, and we assessed correction procedure efficacy. Subsequently, we examined whether corrected scores better predicted levels of performance achievement 6 years after data collection (47 professionals vs. 74 non-professional players) compared with raw scores using point biserial correlations, binary logistic regression models, and DeLong tests. Expectedly, maturity indicators correlated with raw scores (0.16 ≤ | r | ≤ 0.72; ps < 0.05), yet not with corrected scores. Contrary to expectations, corrected scores were not associated with an additional predictive benefit (univariate: no significant r-change; multivariate: 0.02 ≤ ΔAUC ≤ 0.03, ps > 0.05). We do not interpret raw and corrected score equivalent predictions as a sign of correction mechanism futility (more work for the same output); rather we view them as an invitation to take corrected scores seriously into account (same output, one fewer problem) and to revise correction-related expectations according to initial predictive validity of motor variables, validity of maturity indicators, initial maturity-bias, and selection systems. Recommending maturity-based corrections is legitimate, yet currently based on theoretical rather than empirical (predictive) arguments.

The interaction of behavioral context and motivational-volitional factors for exercise and sport in adolescence: patterns matter.

BACKGROUND: In order to generate more effective interventions to promote exercise and sport in adolescence, a better understanding of the interaction of influencing factors across different levels is needed. In particular, motivation and volition for exercise and sport, as well as the context in which adolescents are doing exercise and sport, have been identified as important factors. Behavioral context refers to both the organizational setting, e.g., doing exercise and sport in a club, and the social setting, e.g., doing exercise and sport with friends. Extending previous research, the present study applies a person-oriented approach and aims to identify typical behavioral context patterns and motivational-volitional patterns. To validate the patterns, it was examined whether they differ concerning the exercise and sport activity level. Furthermore, the study investigated how behavioral context patterns and motivational-volitional patterns interact. METHOD: A cross-sectional design with 1155 adolescents (Mage = 15.29; 53% female) was applied. A latent profile analysis was used twice to identify typical patterns: once with eight organizational and social setting factors to examine behavioral context patterns, and once with five motivational-volitional factors to examine motivational-volitional patterns. To validate the patterns identified, the exercise and sport activity level were compared across the patterns using Wald-tests. Finally, transition probabilities and odds ratios were calculated in order to investigate the interaction of the behavioral context and motivational-volitional patterns. RESULTS: Four behavioral context patterns - differing in activity level - were identified: Mostly inactive, non-club-organized individualists, self-organized individualists and family sportspersons, and traditional competitive club athletes with friends. Furthermore, five motivational-volitional patterns emerged with differing activity levels: three level patterns with overall low, moderate or high motivation and volition, and two shape patterns called the intention- and plan-less and the plan-less motivated. Regarding interaction, the results indicate that one behavioral context pattern is not solely responsible for moderate to high motivation and volition in adolescents. CONCLUSION: Applying a person-oriented approach allows a more differentiated view of how behavioral context and motivational-volitional factors interact within homogenous subgroups. This, in turn, provides a basis to design tailored multilevel interventions which account for the interaction of influencing factors across different levels.

Achievement-Motivated Behavior in Individual Sports: Evidence for the Construct and Criterion Validity of the AMBIS-I Coach-Rating Scale.

The coach-rating scale for Achievement-Motivated Behavior in Individual Sports (AMBIS-I) was constructed to measure achievement motivation, not from athletes' own views but from coaches' perspectives. The tool was already checked for reliability as well as content, factorial, and concurrent criterion validity (Zuber and Conzelmann, 2019). To further establish construct and criterion validity, two different samples were involved. Sample 1 included 67 experienced coaches rating their 278 athletes on the three AMBIS-I dimensions proactivity, ambition and commitment. In sample 2, 157 athletes completed self-report questionnaires measuring motivational and volitional concepts. Congruent and discriminant construct validity were assessed using the QCV-procedure (Westen and Rosenthal, 2003) by comparing experts' predicted and empirically observed correlations between the coaches' ratings on the AMBIS-I with the self-ratings of validated instruments. Consistent with theoretical expectations, achievement goal orientations, self-determination and self-optimization show significant positive relationships to the AMBIS-I scales, the negatively formulated volitional concepts, negative ones. As indicated by the 0.87 ≤ ralerting-CV ≤ 0.95, the general patterns of the expert's predictions triangulate consistently with the observed correlations. The findings concerning absolute agreement were mixed. Even though the ICCs suggest sufficient to good consistency, the values of rcontrast-CV are considerably lower. To indicate criterion validity, AMBIS-I display medium to large correlations with the actual performance level estimated by the coaches and small to medium correlations with the assigned potential for subsequent success one year later. In summary, we found solid indications, that AMBIS-I is a valid measure of achievement-motivated behavior in individual sports from coaches' perspective.

Science or Coaches' Eye? - Both! Beneficial Collaboration of Multidimensional Measurements and Coach Assessments for Efficient Talent Selection in Elite Youth Football.

Due to the tremendous popularity of youth football, practitioners in this domain face the ongoing question of the most effective solutions in early talent selection. Although the scientific community has suggested multidimensional models for some time, coach assessments and motor performance tests remain common. Earlier research has determined the strengths and weaknesses within these different approaches. The current investigation directly compared the effectiveness of each approach in talent selection (coach assessment vs. motor performance tests vs. multidimensional data). A sample of 117 youth football players, their parents, and coaches participated in multidimensional measurements in the U14 age category (coach assessments, motor performance tests, psychological characteristics, familial support, training history, and biological maturation). The area under the curve (AUC [95% CI]) from receiver operating characteristic indicated the prognostic validity of each approach in predicting U19 player status five years after the assessments (professional vs. non-professional). Motor performance tests (0.71 [0.58; 0.84]) showed a lower AUC than the multidimensional data (0.85 [0.76; 0.94], p = 0.02), whilst coach assessments did not differ from the two others (.82 [.74; .90]). Further, combined talent selection approaches, especially the use of coach assessments and multidimensional data together, were significantly better at predicting U19 player status (0.93 [0.87; 0.98], p = 0.02 vs. multidimensional data only). Although certain limitations may impede further insights (summation of data, skipped use of non-linear statistics), scientific claims for using multidimensionality within talent selection were confirmed to be fruitful. In particular, the combination of the subjective coaches' eye with scientific data may buffer the mutual weaknesses of these different approaches. Future research should focus on optimizing the output of promising multidimensional models. Knowledge of detailed values relating to specific dimensions within these models and the implementation of enhanced non-linear statistics may enable further improvements in the field of talent selection.

The Brainfit study: efficacy of cognitive training and exergaming in pediatric cancer survivors - a randomized controlled trial.

BACKGROUND: Cancer survival comes at a price: pediatric cancer survivors bear a high risk for a wide range of cognitive difficulties. Therefore, interventions targeting these difficulties are required. The aim of the present clinical trial is to extend empirical evidence about efficacy of cognitive and physical training in pediatric cancer survivors. It is hypothesized that early cognitive and physical interventions affect the remediation of pediatric cancer survivors in terms of improved executive functions (primary outcome). Additional positive effects of cognitive and physical intervention to other areas such as memory and attention are expected (secondary outcome). Changes in cognitive performance are expected to be associated with structural and functional changes in the brain. METHODS: Overall, 150 pediatric cancer survivors and 50 matched controls will be included in this trial. The cancer survivors will be randomly assigned to either a computerized cognitive training, a physical training (exergaming) or a waiting control group. They will be assessed with neuropsychological tests, tests of sport motor performance and physical fitness before and after 8 weeks of training and again at a 3-months follow-up. Moreover, neuroimaging will be performed at each of the three time points to investigate the training impact on brain structure and function. DISCUSSION: With increasing cancer survival rates, evidence-based interventions are of particular importance. New insights into training-related plasticity in the developing brain will further help to develop tailored rehabilitation programs for pediatric cancer survivors. TRIAL REGISTRATION: KEK BE 196/15; KEK ZH 2015-0397; ICTRP NCT02749877 ; date of registration: 30.11.2016; date of first participant enrolment: .18.01.2017.

Motivational patterns as an instrument for predicting success in promising young football players.

Psychological characteristics are crucial to identifying talents, which is why these are being incorporated in today's multidimensional talent models. In addition to multidimensionality, talent studies are increasingly drawing on holistic theories of development, leading to the use of person-oriented approaches. The present study adopts such an approach by looking at the influence that motivational characteristics have on the development of performance, in a person-oriented way. For this purpose, it looks at how the constructs achievement motive, achievement goal orientation and self-determination interact with one another, what patterns they form and how these patterns are linked to subsequent sports success. Ninety-seven top young football players were questioned twice. Another year later, it was enquired which of these players had been selected for the U15 national team. At both measuring points, four patterns were identified, which displayed a high degree of structural and individual stability. As expected, the highly intrinsically achievement-oriented players were significantly more likely to move up into the U15 national team. The results point to the importance of favourable patterns of motivational variables in the form of specific types, for medium-term performance development among promising football talents, and thus provide valuable clues for the selection and promotion of those.

Cognitively Engaging Chronic Physical Activity, But Not Aerobic Exercise, Affects Executive Functions in Primary School Children: A Group-Randomized Controlled Trial.

Although the positive effects of different kinds of physical activity (PA) on cognitive functioning have already been demonstrated in a variety of studies, the role of cognitive engagement in promoting children's executive functions is still unclear. The aim of the current study was therefore to investigate the effects of two qualitatively different chronic PA interventions on executive functions in primary school children. Children (N = 181) aged between 10 and 12 years were assigned to either a 6-week physical education program with a high level of physical exertion and high cognitive engagement (team games), a physical education program with high physical exertion but low cognitive engagement (aerobic exercise), or to a physical education program with both low physical exertion and low cognitive engagement (control condition). Executive functions (updating, inhibition, shifting) and aerobic fitness (multistage 20-m shuttle run test) were measured before and after the respective condition. Results revealed that both interventions (team games and aerobic exercise) have a positive impact on children's aerobic fitness (4-5% increase in estimated VO2max). Importantly, an improvement in shifting performance was found only in the team games and not in the aerobic exercise or control condition. Thus, the inclusion of cognitive engagement in PA seems to be the most promising type of chronic intervention to enhance executive functions in children, providing further evidence for the importance of the qualitative aspects of PA.

DELAYED POSITIVE EFFECTS OF AN ACUTE BOUT OF COORDINATIVE EXERCISE ON CHILDREN'S ATTENTION (1).

Since attention is an important prerequisite for learning, it is particularly worthwhile to promote it in schools, through specific interventions. The present study examined the effects of an acute bout of coordinative exercise in physical education on the attention of primary school children. A total of 90 fifth grade primary school children (41 boys, 49 girls; M = 11.0 yr., SD = 0.6) participated in the study and were randomly assigned to either the experimental or the control group. The experimental group received a cognitively demanding physical education lesson consisting of different coordinative exercises; the control group attended a normal sedentary school lesson. Before, immediately after, and 90 min. after each experimental condition, the children's attentional performance was tested using the revised version of the d2 Test of Attention (d2-R). Results of the repeated-measures analysis of variance (ANOVA) revealed that children's attentional performance increased through the specifically designed physical education lesson, not immediately but 90 min. after cessation. The results are discussed in terms of mechanisms explaining the relationship between acute physical exercise, and immediate and delayed effects on attention.

Overcoming adversity during the COVID-19 pandemic: Longitudinal stability of psychosocial resource profiles of elite athletes and their association with perceived stress.

Previous research has demonstrated that psychosocial resources are associated with elite athletes' perceived stress. However, these resources have mainly been studied separately. Using a person-oriented approach, this study aimed to identify meaningful profiles of athletes' psychosocial resources, their stability over time, and their relationship with perceived stress during the COVID-19 pandemic. To identify such patterns, separate latent profile analyses (LPA) at two measurement points T1 (June 2020) and T2 (March 2021) and a subsequent latent transition analysis (LTA) were conducted with athletic identity, resilience, perceived social support, and self-esteem for a sample of 373 Swiss elite athletes. Perceived stress was analyzed at and between T1 and T2 with a mixed-design ANOVA. For LPA, theoretical considerations and statistical criteria led to a solution of four profiles: (1) Athletic Identifiers With Above-Average Resources (nT1 = 235; nT2 = 240), (2) Below-Average Athletic Identifiers With Below-Average Resources (nT1 = 84; nT2 = 90), (3) Variable Athletic Identifiers With Below-Average Internal and Clearly Below-Average External Resources (nT1 = 14; nT2 = 7), and (4) Athletic Identifiers With Below-Average Internal and Above-Average External Resources (nT1 = 40; nT2 = 36). For LTA, both structural and individual stability was demonstrated. A large and significant main effect of perceived stress was observed for resource profiles, while there was no significant main effect for measurement point nor interaction effect. Direct comparisons revealed that Athletic Identifiers With Above-Average Resources perceived significantly less stress than the other profiles at both time points. In conclusion, regardless of psychosocial resource profile, the perceived stress of elite athletes was stable during the COVID-19 pandemic, but exhibiting a pattern with high psychosocial resources seems to buffer against stress compared to a lack of specific resources. Therefore, sport federations and practitioners should provide tailored support programs to help athletes build all these resources.

Veridicality of self-concept of strength in male adolescents.

Changes in physical self-concept and veridicality (i.e., the appropriateness of one's self-perceptions to reality) during childhood and adolescence are related to performance in physical fitness, exercise, and global self-esteem, particularly in male adolescents. This cross-sectional study examined the relation between the self-concept of strength and actual strength in groups of male adolescents ages 12 to 15 years. For this purpose, 889 male adolescents (M age = 13.2 yr., SD = 1.0) were questioned about their self-concept of strength, after which a test of strength was carried out. The results showed that the correlation between self-concept of strength and actual strength was higher in older (14- and 15-year-old) than younger (12- and 13-year-old) adolescents. There was a statistically significant association between age group and veridicality, indicating that realistic self-concept is underrepresented among younger, but overrepresented among older adolescents. No association was found between the adolescents' physical activity and veridicality. The consequences for further research on the development of veridicality in the physical domain are discussed.

Mechanistic or Relational Worldview for Talent Identification Research in Sport Science? Both-But With a Preference!

This paper situates talent identification research in sport science within the broader context of developmental science, offering a conceptual framework informed by two (meta-)theoretical worldviews: the Cartesian-split-mechanistic and processual-relational worldviews. Although these worldviews are not explicitly named in the field of talent identification research, we demonstrate their implicit adoption through theoretical and methodological discourse. After comparing applications, benefits, and limitations of each worldview, we briefly discuss whether their bodies of knowledge are incompatible, competitive, or complementary. We suggest each worldview provides complementary insights with a penchant for generating nomothetic and group-specific and type-specific and idiographic knowledge, respectively.

Process Development of a Generative Method for Partial and Controlled Integration of Active Substances into Open-Porous Matrix Structures.

A special generative manufacturing (AM) process was developed for the partial integration of active ingredients into open-porous matrix structures. A mixture of a silver-containing solution as an antibacterial material with an alginate hydrogel as a carrier system was produced as the active ingredient. The AM process developed was used to introduce the active ingredient solution into an open-porous niobium containing a ß-titanium matrix structure, thus creating a reproducible active ingredient delivery system. The matrix structure had already been produced in a separate AM process by means of selective laser melting (SLM). The main advantage of this process is the ability to control porosity with high precision. To determine optimal surface conditions for the integration of active ingredients into the matrix structure, different surface conditions of the titanium substrate were tested for their impact on wetting behaviour of a silver-containing hydrogel solution. The solution-substrate contact angle was measured and evaluated to determine the most favourable surface condition. To develop the generative manufacturing process, an FDM printer underwent modifications that permitted partial application of the drug solution to the structure in accordance with the bioprinting principle. The modified process enabled flexible control and programming of both the position and volume of the applied drug. Furthermore, the process was able to fill up to 95% of the titanium matrix body pore volume used. The customised application of drug carriers onto implants as a drug delivery system can be achieved via the developed process, providing an alternative to established methods like dip coating that lack this capability.

The road to excellence in women's football: a retrospective cohort study over the last 30 years with Swiss national players.

OBJECTIVES: This study examines the training (age at club entry, hours in club practice, free play, other sports) and environmental characteristics (popularity, media coverage, school and parental support) influencing the development of female Swiss national team players in elite football over a three-decade period. METHODS: A retrospective questionnaire was completed by 84 participants, who were divided into three cohorts based on their first game with the Swiss national team (C1 = until 2000, n = 24; C2 = 2001-2010, n = 29; C3 = 2011-2022, n = 31). ANOVAs were employed to compare the cohorts regarding training and environmental variables. RESULTS: The findings demonstrate better perceived environmental conditions, stagnating volume of free play and other sports in childhood, decreasing age at club entry, and increasing club practice and total training volume across cohorts. CONCLUSION: Practical implications highlight talent development avenues in unstructured settings during free time and in the micro-structure of club practice.

Retirement from elite sport and self-esteem: a longitudinal study over 12 years.

This study examined the complex associations between athletic retirement and self-esteem among former elite athletes. With reference to theoretical and empirical work on the quality of the transition out of sport, information was collected from 290 (junior) elite athletes in a retrospective-prospective design: at the first measurement, active athletes assessed satisfaction with their sporting career, athletic identity, and self-esteem. At the second measurement (12 years later), the now former athletes rated transition characteristics of their career ending, sporting career success, emotional reactions to career termination, extent of necessary adjustment required following athletic retirement, duration and quality of adjustment, and self-esteem. Structural equation modelling revealed that neither sporting career success nor sporting career satisfaction had a direct effect on adjustment. However, athletic identity and retirement planning predicted the extent of adjustment, which in turn predicted the duration and quality of adjustment, and ultimately self-esteem. Voluntariness, timeliness, and perceptions of gain predicted emotional reactions towards career termination, which also predicted the duration of adjustment. Extent of adjustment and emotional reactions mediated between preconditions of career termination and transition characteristics and self-esteem. While self-esteem after career termination was predominantly predicted by self-esteem 12 years earlier, perceived quality of adjustment to career termination had a significant effect on self-esteem in the post-athletic career. These results complement existing literature illustrating that athletic retirement is a complex and dynamic process and the quality of this transition has a small, but still noteworthy effect on self-esteem, a central construct for well-being.

Closing a chapter? A protocol for a longitudinal mixed methods study on retirement from elite sport.

Retirement from elite sport represents a major life transition for athletes and requires them to redefine their central life projects, identities, and perhaps even sources of meaning in life. Although an extensive body of literature has identified risk and protective factors in career termination, little is known about the more subjective processes and individual pathways of athletes as they establish their new relationship with work-life and sport. The planned longitudinal mixed methods study follows Swiss elite athletes' transition with a focus on understanding (1) the relationship between psychological resources, life situations at the end of the sports career, and the retirement process; (2) how athletes' post-retirement vocational careers interact with their subjective careers and sense of meaningful work; (3) how athletes reconstruct their identities and relationship with sport over time; and (4) how gender shapes athletes' pathways and reorientation of their life design.Using a person-oriented approach combined with narrative inquiry, we expect to identify specific types and stories which demonstrate individual differences in career and personal development throughout the transitional period, an understanding of which can be targeted towards support programmes for retiring elite athletes. As the study centralises dimensions of positive psychological functioning (meaning and purpose in life/sport/work, resilience, life satisfaction), it complements previous studies focused on psychological distress and provides much needed knowledge that can be used to foster well-being in athletic retirement. Collaborating with the Swiss Olympic Association helps to ensure that the research findings will be disseminated to relevant end-users and used towards developing socially sustainable elite sport for the future generations.

Period prevalence of SARS-CoV-2 infections and willingness to vaccinate in Swiss elite athletes.

Objectives: (1) To assess the period prevalence of SARS-CoV-2 infections and willingness to vaccinate in Swiss elite athletes and (2) to evaluate whether sociodemographic and sport-related characteristics were associated with infection of SARS-CoV-2 in athletes. Methods: A total of 1037 elite athletes (Mage=27.09) were surveyed in this cross-sectional study. They were asked whether they had been infected with SARS-CoV-2 and whether they would like to be vaccinated. Characteristics of a possible COVID-19 illness were also recorded. Results: During the first year of the pandemic, 14.6% of all Swiss elite athletes were found to be infected with SARS-CoV-2, and 5.4% suspected that they had been infected. Male athletes, young athletes and team sports athletes had an increased likelihood of being infected with SARS-CoV-2. There was considerable heterogeneity in the duration and severity of a COVID-19 illness in athletes. Overall, 68% of respondents indicated a willingness to be vaccinated if they were offered an opportunity to do so. Conclusion: In the first year of the pandemic, Swiss elite athletes were tested more often positive for SARS-CoV-2 than the general Swiss population. Because COVID-19 illness can impair health for a relatively long time, sports federations are advised to motivate athletes to be vaccinated.
