Background: Although athletes seem to hold uniform views towards non-dopers, their perception of dopers is more nuanced, reflecting positive and negative attributes. Research also indicates that rarely a single factor can explain doping, but a host of reasons that intertwine. A holistic understanding of how values play a role in decisions in anti-doping and the elements that influence athletes' doping vulnerability is timely and warranted., Methods: We recruited elite athletes from 13 countries representing 27 sports at a national or international level ( N  = 60) to participate as part of a larger research project. Data were collected via focus group interviews focusing on values, value priorities and perceptions about the role of values in doping as a phenomenon and in dopers' actions. Data were analysed using iterative thematic analysis., Results: Three themes were identified: (1) athletes' personal stance on doping, (2) dopers in the eyes of the anti-doping-compliant athletes, and (3) doping vulnerability is a balance. Athletes in this study strongly opposed doping but showed empathy and understanding toward athletes who doped under certain circumstances. Furthermore, athletes believed that "clean" and "doping" athletes are not always distinguished by the values they hold, leading to the realisation that all athletes can be vulnerable to doping at some point. This vulnerability is a balance between risks and protective factors in a complex interaction between environmental, personal, and situational influences. Each element (e.g., values, environment) can be a motivator or a barrier. Consequently, doping vulnerability is highly idiosyncratic and dynamic., Conclusion: If doping is not due to a lack of moral values but the consequences of combined risk factors that override the guiding function of values, then doping can happen to anyone, "good" athletes included. Developers and facilitators of anti-doping education programmes are advised to embrace this important aspect. The results also contribute to developing the doping vulnerability concept as a balance between risks and protective factors and draw attention to the clean athlete vulnerability, which is rooted in the combination of strategic performance enhancement via non-prohibited means, their exposure to anti-doping requirements and the constant high level of suspicion that surrounds them., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Veltmaat, Dreiskämper, Brueckner, Bondarev, Heyes, Barkoukis, Elbe, Lazuras, De Maria, Zelli and Petróczi.)

The "11 for Health in Denmark" in-school educational football program has shown to have numerous positive physiological and psychological effects in 10- to 12-year-old schoolchildren. A key part of the successful application of the program, however, has not yet been examined, namely the motivational processes underlying participation and behavioral changes. This study examined such motivational processes (i.e., autonomous motivation, beliefs, and intentions) using the trans-contextual model (TCM) and investigated if the 11 for Health in Denmark program increased intentions to participate in physical activity (PA) outside of school in 10- to 12-year-old schoolchildren. Using a web-based questionnaire, Danish-speaking schoolchildren (N = 276 [boys, 50.4%]; M age  = 10.44, SD = 0.35) from three schools and seven classes completed TCM-based questionnaires at three time-points (weeks 0, 1, and 5) while participating in the 11 for Health in Denmark program. Single-indicator structural equation modeling was performed to examine goodness-of-fit and parameter estimates. A path analysis using maximum likelihood estimation was used to test the direct and indirect effects of the TCM model. The results partly supported a mediation sequence, as we found significant direct effects in eight of 13 motivational variables (β = -0.25-0.83, p < 0.05), indirect effects in one of nine variables (β = 0.15, p < 0.01), but no effects with regard to PA behavior. Findings provide evidence for a motivational link between Danish-speaking schoolchildren's autonomous and controlled motivation from in school to out of school, and may inform future interventions promoting motivation and participation in out of school PA., (© 2022 The Authors.

This study aimed to investigate athletes' hypothetical use of non-steroidal anti-inflammatory drugs (NSAIDs), a behavior similar to doping, and its association with doping attitudes, competitive anxiety and situational opportunity. One hundred twenty-two sport science students completed an online survey assessing biographical information, doping attitudes, and competitive anxiety. Students' intention to use analgesics was measured via two different hypothetical situations using the vignette technique. The favorable situation included an absence of potential witnesses and presence of an attractive good whereas witnesses were present in the unfavorable situation and an attractive goal was absent. The results of two hierarchical multiple regression models showed that doping attitudes and competitive anxiety, especially worry, predicted the use of analgesics. In the situation featuring a favorable opportunity, worry was the strongest predictor, whereas in the situation of an unfavorable opportunity, doping attitudes was the strongest predictor for using NSAIDs. Results indicate that NSAID use is associated with positive attitudes toward doping and competitive anxiety, and that it is situationally dependent. Future research perspectives and practical implications are discussed., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Melzer, Elbe and Strahler.)

Doping has serious negative consequences for athletes and the integrity of sports, implying the need for effective prevention programs. Since educating young athletes about doping-related knowledge is deemed to be not sufficiently effective to minimize doping, a focus on values, emotions and morality is seen as a promising approach and previous research indicates which variables exactly could be addressed in anti-doping efforts. These variables are anticipated guilt, empathy, moral disengagement, and collective moral norms, since these constructs have been strongly and consistently linked to doping intention, likelihood, or behavior. Therefore, the purpose of this study was to develop a values-based anti-doping intervention, which targets the aforementioned variables, and to evaluate its effectiveness in producing changes in outcomes in comparison to an information-based intervention and a waiting control group. To evaluate their effectiveness, both interventions, which each consist of six 45-min sessions (one session per week) were implemented in a sample of 321 young elite athletes, aged 13-19 years, from a broad range of team and individual sports. Thirty different teams, training groups or classes were randomly assigned to either the values-based intervention, the information-based intervention, or to a waiting control group. Doping intention, doping susceptibility as well as the above mentioned variables were assessed at pre- and posttest and, for participants of the values- and information-based conditions also at a 3 to 4-month follow up. Within a multilevel modeling framework general linear mixed regression analyses revealed that the values-based intervention, compared to the control group, was able to decrease athletes' moral disengagement and increase their anticipated guilt immediately after the intervention (at posttest), whereas no effects for the information-based intervention emerged. Looking at how the outcomes developed over time (i.e., at the follow up measurement), it could be demonstrated that the reduction in moral disengagement sustained. The increase in anticipated guilt, however, was not sustainable and, surprisingly, decreased from post to follow up. Furthermore, athletes in the values-based intervention reported higher empathy from post to follow up, which could possibly indicate a "delayed" effect. This study provides support that a values-based approach can produce changes in some, yet, not all addressed variables and specific elements from this intervention could potentially be a useful addition to traditional anti-doping education (i.e., information provision)., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Manges, Seidel, Walter, Schüler and Elbe.)

Abstract: Madsen, M, Larsen, MN, Cyril, R, Møller, TK, Madsen, EE, Ørntoft, C, Lind, RR, Ryom, K, Christiansen, SR, Wikman, J, Elbe, AM, and Krustrup, P. Well-being, physical fitness, and health profile of 2,203 Danish girls aged 10-12 in relation to leisure-time sports club activity-with special emphasis on the five most popular sports. J Strength Cond Res 36(8): 2283-2290, 2022-This study investigated the relationship between leisure-time sports club activities and well-being as well as physical health parameters in 10-12-year-old Danish girls. Two thousand two hundred three girls took part in the study, which included questionnaires on participation in leisure-time sports clubs, well-being, Yo-Yo intermittent recovery level 1 children's test, long jump, balance tests, body composition, blood pressure (BP), and resting heart rate (RHR). Data were analyzed according to whether the girls participated in leisure-time sport and according to the 5 most frequently reported sports. Girls enrolled in leisure-time sports had higher physical well-being (49.3 ± 8.6 vs. 45.2 ± 8.3), psychological well-being (50.4 ± 9.0 vs. 49.4 ± 9.8), experienced more peer and social support (50.2 ± 10.0 vs. 48.9 ± 10.7), and perceived a more positive school environment (52.5 ± 8.0 vs. 50.5 ± 9.3), as well as showing higher Yo-Yo (+39%), long jump (+10%), and balance performance (+15%) than girls not involved in sport clubs. The girls active in sports clubs had higher relative muscle mass (+5%), lower fat percentage (-11%), body mass index (-5%), RHR (-3.4 b·min -1 ), and diastolic BP (-1.4 mm Hg) compared with girls not involved in sport ( p < 0.05). Girls who played soccer showed higher aerobic fitness compared with inactive girls (+67%), dancers (+39%), swimmers (+38%), and gymnasts (+16%). Gymnasts had a lower fat percentage than inactive girls (-19%), team handballers (-10%), swimmers (-12%), and soccer players (-4%). Girls participating in club-based leisure-time sports showed higher well-being and better fitness and health profiles than girls not involved in any sports club activities. Girls involved in soccer had better aerobic fitness and gymnasts a lower fat percentage., (Copyright © 2020 National Strength and Conditioning Association.)

Elite football can make players feel nervous, and personality characteristics, as well as experience, affect how well pressure is handled before important games. Studying the psychological characteristics of female football players can provide information on how well psychological pressure is handled and generate knowledge on how to support players in order to improve performance. Based on a sample of 128 female elite football players from 8 top-level teams, the present study investigates whether psychological characteristics and football experience/player stus in elite female football players can predict state anxiety before important matches. Our results outline that high age and national team experience negatively predicted most of the trait anxiety subscales. In line with previous research, no psychological differences were found between goalkeepers, defenders, midfielders, and strikers while starting players revealed to have significantly lower trait anxiety. When measuring before important matches, we found that somatic state anxiety was negatively associated with senior national team experience and positively associated with worry trait anxiety and fear of failure. Cognitive state anxiety was negatively associated with hope for success and positively associated with somatic and worry trait anxiety. Self-confidence was positively associated with youth national team experience and negatively associated with worry trait anxiety. It can be concluded that psychological characteristics and national team experience are both important for optimal state anxiety before important matches in elite-level women's football. Implications for practice and future research are discussed., (This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.© 2020 The Authors.

The "11 for Health in Denmark" concept aims to enhance 10-12-year-old schoolchildren's physical activity levels and health knowledge through an 11-week football intervention and has been shown to induce positive effects in numerous areas. However, little is known about the implementation facilitation of this concept in schools. This case study therefore aims to gain a deeper understanding of the implementation facilitation of "11 for Health" in a Danish 5 th grade class comprising 22 schoolchildren (12 boys and 10 girls, M age 11.86±) and one teacher. Data were derived from multiple school situations using photographs and videos, observations, and informal interviews. Five themes were identified: (1) environmental and organizational factors impacting on the implementation; (2) familiarization with the concept for the teacher and schoolchildren; (3) previous clique formation; (4) the central role of the teacher; and (5) the importance of how praise partners are allocated. We found high adherence to the "11 for Health" concept, in which the teacher played a key role by applying an autonomy-supportive style of teaching and using the praise partner concept in a suitable manner. A clique of football-playing boys was a resource, as their praising of classmates encouraged adherence. However, familiarization with the "11 for Health" concept was a challenge and the clique's competitive nature occasionally built barriers to other schoolchildren without football experience, potentially leading to a more controlled form of motivation. Based on the results, we encourage teachers to apply autonomy-supportive teaching when applying the "11 for Health" concept., (© 2021 The Authors.

Objectives: This study investigated the effects of the health promotion intervention "11 for Health in Denmark" program on 10- to 12-year-old ethnic minority schoolchildren's enjoyment, health knowledge, well-being, and fitness., Methods: 1122 Danish 5th grade schoolchildren with ethnic minority background from 154 schools were randomized (5:1) to an intervention group (IG, n = 944) or a control group (CG, n = 178). The IG and CG were also divided into subgroups of children active in a sports club (IGPA: n = 644; CGPA: n = 122) and not active in a sports club (IGPI: n = 300, CGPI: n = 56). IG participated in the "11 for Health in Denmark" 11-week program, consisting of 2 × 45 min per week of football drills, small-sided games, and health education, whereas CG continued their regular activities. Pre-post physical testing and questionnaires were applied (short version of the multidimensional well-being questionnaire KIDSCREEN-27, and a 34-item health knowledge questionnaire)., Results: The "11 for Health in Denmark" program was rated moderate-to-high on a 1-5 scale for enjoyment by girls (3.57) and boys (3.65). The intervention had positive between-group effect on health knowledge in relation to hygiene (IG vs GC: 10.6% points (CI95%: 6.9:14.3), p < 0.05), nutrition (9.6% point (CI95%: 7.4:11.8), p < 0.01) and physical activity 4.4% points (CI95%: 2.2:6.6) as well as overall health knowledge (5.7% points, (CI95%: 4.3;7.1), p < 0.05), with similar effects for girls and boys. The IGPI subgroup showed a positive effect on well-being (p = 0.04, school and learning) and also fitness effects on performance and VO 2  max (p = 0.02: p = 0.01). The IGPA subgroup showed a positive effect on fitness scores (p = 0.02, BMI)., Conclusion: The intervention program was enjoyable and had a positive impact on health knowledge of ethnic minority background schoolchildren. In addition, the intervention program had the strongest positive effects on well-being and fitness scores for the non-sports club-active children., (© 2021 John Wiley & Sons A/S.

Objectives: This study investigated the correlation between sports club activities and well-being and physical health parameters in 10-12 years old boys., Design: Cross sectional., Setting: Danish schools., Participants: 2293 boys took part in the study., Primary and Secondary Outcome Measures: Questionnaires on participation in sports clubs and well-being and testing of physical health profile through measurement of body composition, resting heart rate (RHR), blood pressure and postural balance, jump and Yo-Yo IR1C performance. Data were analysed by participation in sport and according to the five most frequently reported sports., Results: Boys enrolled in sports clubs had higher physical well-being (51.7±9.7 vs 45.9±8.7) and psychological well-being (53.3±9.6 vs 51.4±10.0), experienced more peers and social support (50.9±9.9 vs 48.0±11.6), and had a more positive perception of the school environment (48.6±7.5 vs 45.9±8.1) than boys not involved in sports clubs. In addition, they showed better Yo-Yo IR1C (+46%), long jump (9%) and balance test performance (+20%). The boys active in sports clubs had higher relative muscle mass (+6%) and lower fat percentage (-3%), body mass index (-6%) and RHR (-5%) compared with boys not involved in sports clubs (p<0.05). Boys enrolled in football clubs had higher aerobic fitness compared with boys not active in clubs (+11%), handball players (+5%), swimmers (+8%) and badminton players (+7%). Moreover, the boys enrolled in football clubs had lower fat percentage (-17%) and higher relative muscle mass (+4%) than swimmers., Conclusion: Boys participating in club-based sports showed markedly higher levels of well-being and better physical health profiles than boys not involved in sports club activities. Footballers had superior aerobic fitness and body composition compared with those active in other sports. Results suggest that sports club activities seem to be beneficial for young boys' well-being, fitness and physical health profile, with the greatest benefits achieved by boys involved in football., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Background: In Denmark, the first COVID-19 pandemic lockdown resulted in a compact season finisher for elite footballers, potentially impacting their mental health. Purpose: This study aimed to investigate the protective role of resilience and the impeding role of trait anxiety on elite footballers' level and variability of well-being and emotional stability. Material and Methods: One hundred and twenty-five male elite-level players ( M age  = 25.04 ± 4.82) completed baseline measures on trait anxiety and resilience. Additionally, well-being and positive and negative affect were assessed before games (n = 24) over 62 days. Separate two-level regression analysis using Bayesian statistics was conducted to test potential relationships. Results: Results show a credible positive relationship between the average level of well-being and within-person variability over time as well as the average level in positive affect. This indicates that resilience might be a protector for mental health. In addition, higher levels of trait anxiety (i.e., subscale concentration disruption ) were associated with higher levels of negative affect and higher variability over time. This indicates that trait anxiety might facilitate negative affect. No other credible relationships were found. Conclusion: High resilience and low trait anxiety are identified as relevant factors for mental health within elite footballers during COVID-19. Implications for practice are discussed.

ObjectivesOur large-scale cluster randomised controlled trial aimed to investigate the effects on health knowledge and enjoyment of an 11 week 'health education through football' programme for children aged 10-12 years old. Methods 3127 Danish school children (49% girls) aged 10-12 years from a total of 154 schools located in 63% of the Danish municipalities (69 of 98) took part in the analysis. A 5:1 cluster randomisation was performed at school level for the intervention group (IG) or the control group (CG). The twice-weekly 45 min intervention was the '11 for Health in Denmark' programme, which includes health education, football drills and small-sided games. The health education element focused on hygiene, nutrition, physical activity and well-being. Outcomes: The participants completed a 34-item multiple-choice computer-based health knowledge questionnaire preintervention and postintervention. IG also evaluated whether the programme was enjoyable. Results Between-group differences (p<0.05) were observed in overall health knowledge in favour of IG (+7.2% points, 95% CI 6.1% to 8.4%, effect size, ES:0.59), with similar effects for girls (+7.4% points, 95% CI 5.9% to 9.0%, ES:0.57) and for boys (+7.0% points, 95% CI 5.3% to 8.7%, p<0.05, ES:0.51). Marked between-group differences were observed in favour of IG, for health knowledge related to hygiene (IG vs CG:+13.9% points, 95% CI 11.1% to 16.7%, ES:0.53), nutrition (+10.3% points, 95% CI 8.5% to 12.1%, ES:0.53), physical activity (+5.9% points, 95% CI 4.1% to 7.7%, ES:0.36) and well-being (+4.4% points, 95% CI 2.7% to 6.1%, ES:0.28). Both girls and boys gave the programme moderate to high scores for enjoyment (3.6±1.0 and 3.7±1.1, respectively). Conclusion Health education through sport, using the '11 for Health' model, was enjoyable for girls and boys aged 10-12 years old, and improved health knowledge related to hygiene, nutrition, physical activity and well-being., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Doping violates the Spirit of Sport and is thought to contradict the values which underpin this spirit. Values-based education (VBE) has been cited as a key element for creating a clean sport culture across age groups. Culturally relevant VBE requires understanding of the values that motivate athletes from different countries to practice their sport and uphold clean sport values. WADA's new International Standards for Education makes this study both needed and timely. Overall, 1,225 athletes from Germany, Greece, Italy, Russia, and the UK responded to measures assessing their general values, Spirit of Sport values, and their perceived importance of "clean sport". MaxDiff analysis identified the most important values to participants based on their respective country of residence. Correlation analysis was conducted to assess the relationship between importance of clean sport and Spirit of Sport values. There were significant differences between participant nationality and their perceived importance of clean sport [ F (4, 1,204) = 797.060, p < 0.000], the most important general values ( p < 0.05), and Spirit of Sport values ( p < 0.05). Moderate positive correlations were observed between the perceived importance of clean sport and honesty and ethics ( r = 0.538, p < 0.005) and respecting the rules of sport ( r = 0.507, p < 0.005). When designing the values-based component of anti-doping education programs, athletes' different value-priorities across countries should be considered., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Woolway, Elbe, Barkoukis, Bingham, Bochaver, Bondarev, Hudson, Kronenberg, Lazuras, Mallia, Ntovolis, Zelli and Petróczi.)

The COVID-19 pandemic is also called a crisis of uncertainty because of so many unforeseeable events like canceled qualification competitions, loss of training facilities, and postponement of the Olympic games. Athletes and their entourage experience this uncertainty as stressful. Sport psychology practitioners (SPPs) are in a key position to support athletes in coping with these unforeseeable stressors. However, SPPs are similarly affected by the COVID-19 pandemic and simultaneously have to cope with stress. Salutogenesis, which describes how to manage stress and to stay well, provides a theoretical approach to how to cope with uncertainty. The salutogenetic approach aims at strengthening individuals' sense of coherence (SoC) and consists of three components, namely comprehensibility, manageability, and meaningfulness. Although it is known that the SoC can be enhanced via psychological skills training, so far, this approach has not been systematically applied to the elite sport context. Athletes have been advised to see SPPs for help; thus, the question of how SPPs handle the time of uncertainty while supporting others emerges. The aim of this contribution was to outline how the salutogenetic approach can be applied to strengthening SPPs' SoC via a single-day four-part workshop. Additionally, we applied the workshop to N = 26 volleyball coaches and evaluated the workshop's effects on participants' psychological aspects [i.e., the Sense of Coherence-Leipziger short version (SoC-L9), resilience (RS-13): coping with uncertainty, affective response, and stress via semantic differentials] and the workshop's quality ratings (i.e., Quality Questionnaire for Sport Psychological Coaching, QS-17). The evaluation provides results that show a positive impact on a descriptive level of the participants' SoC, uncertainty, affect, and stress perception; however, the results show no significant main effect of time [ F (8, 10) = 1.04, p = 0.467, η p 2 = 0.454]. Workshop quality (on average, 3.60 ± 0.35 out of 4.00) and skill acquisition (on average, 3.00 ± 0.64 out of 4.00) were positively evaluated; 82.00% of the participants would use the learned tools in the future. Thus, we outline how this workshop might help strengthen SPPs' SoC and at the same time empower them to strengthen their athletes' SoC. Overall, we add a theoretical (i.e., salutogenesis in sports) and a practical perspective (i.e., coping techniques based on salutogenesis) on how to cope with the COVID-19 pandemic for SPPS, athletes, and their support network., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Leisterer, Lautenbach, Walter, Kronenberg and Elbe.)

The COVID-19 pandemic has negatively impacted mobility worldwide. As a corollary, the health of top- and lower-level athletes alike is profoundly reliant on movement and exercise. Thus, the aim of this study is to understand impacts of the COVID-19 pandemic lockdown on athletes' motivation to exercise and train. In detail, we aim to better understand who (i.e., demographic, sport-specific, and psychological state and trait variables) reported a change in motivation to train due to the lockdown, why they reported lower motivation (i.e., open-ended questions on problems), what they did to help themselves, what support they received from others, and what they are looking forward to after the lockdown (i.e., open questions). Questionnaire data and answers to these open-ended questions were assessed via an online questionnaire, completed by 95 amateur and recreational athletes during the first COVID-19 lockdown in Germany (April to mid-May 2020). Results show that greater numbers of female athletes are less motivated to train in comparison to male athletes ( p = 0.029). No differences in motivation were found regarding type of sport (individual vs. team sport) and number of competitions during the year. Also, more motivated to train amateur and recreational athletes showed lower athletic identity than athletes who reported no change in motivation to exercise during the lockdown ( p = 0.03). Additionally, differences in state emotional, perceived stress, and personality variables (i.e., orientation to happiness, volition) were found between athletes who stated that they were less motivated to train compared to athletes who reported no changes in motivation. In particular, closure of sports facilities and social distancing measures were perceived to be highly problematic. Even though athletes received emotional support, organized themselves via routines and schedules, and trained using online tools, they predominately stated that they wished that their coaches would have supported them more. Understanding the impacts of a pandemic-related lockdown on athletes' motivation, athletes' coping strategies, and their desired support will help better support them in future crises., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Lautenbach, Leisterer, Walter, Kronenberg, Manges, Leis, Pelikan, Gebhardt and Elbe.)

The purpose of the present study was to shed light on the behavioral component of emotions by investigating antecedents and consequences of outward emotional reactions during table tennis competitions. With regards to the antecedents of outward emotional reactions, in line with appraisal theories, we considered the importance and the controllability of the situation as two important constructs. Fifteen table tennis matches, involving in total 21 players (7 females) with a mean age of 16.71 ( SD = 0.70), were video recorded during the finals of the youth National Championship in Greece. Based on the footage, outward emotional reactions after every point were classified as neutral, positive, or negative. Situational factors in relation to the scoring system, bearing the importance and the controllability of the situation, were formed to assess antecedents of outward emotional reactions. To measure the consequences of outward emotional reactions, the impact on the outcome of the next point was assessed. Generalized linear models with a logit link were computed separately for positive outward emotional reactions after having won a point and negative outward emotional reactions after having lost a point. In general, the results show that while situational factors bearing the importance of the situation could predict positive and negative outward emotional reactions, the effects of situational factors bearing the controllability of the situation were less conclusive. In addition, the results also showed interactive effects between the two constructs for both positive and negative outward emotional reactions. With regard to the consequences of outward emotional reactions, negative and positive outward emotional reactions could not predict the outcome of the next point. To conclude, this study highlights the behavioral component of emotions as a viable alternative to enhance our understanding of the role of emotions in sport., (Copyright © 2020 Fritsch, Finne, Jekauc, Zerdila, Elbe and Hatzigeorgiadis.)

Background: The present study investigates the well-being effects for 10- to 12-year-old children  who participated in the school-based intervention "11 for Health in Denmark," which comprises physical activity (PA) and health education. Subgroup analyses were carried out for boys and girls., Method: Three thousand sixty-one children were randomly assigned to an intervention group (IG) or a control group (CG) by 5:1 cluster randomization by school. 2533 children (mean age 11.5 ± 0.4; 49.7% boys) were assigned to IG and 528 children (mean age 11.4 ± 0.5; 50.8% boys) were assigned to CG. IG participated in the "11 for Health in Denmark" 11-week program, consisting of 2 × 45 min per week of football drills, small-sided games, and health education. CG did not participate in any intervention and continued with their regular education. Before and after the intervention period, both groups answered a shortened version of the multidimensional well-being questionnaire KIDSCREEN-27., Results: The "11 for Health in Denmark" intervention program had a positive effect on physical well-being in girls (IG: 48.6 ± 8.5 to 50.2 ± 9.3), whereas the improvement was not significant in boys. The program also had a positive impact on well-being scores for peers and social support (IG: 50.2 ± 10.2 to 50.8 ± 10.1), though when analyzed separately in the subgroups of boys and girls the changes were not significant. No between-group differences were found for psychological well-being or school environment., Conclusion: The intervention program had a positive between-group effect on physical well-being in girls, whereas the change was not significant in boys. The overall scores for peers and social support improved during the intervention period, but no subgroup differences were found., (© 2020 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

This study investigated whether the physical fitness and body composition of 10-12-year-old Danish children are related to participation in leisure-time club-based sporting activities. The study involved 544 Danish 10-12-year-old 5th-grade municipal schoolchildren (269 boys and 275 girls, 11.1 ± 0.4 years). After answering a questionnaire about leisure-time sporting activities, the children were divided into four groups: football club participation (FC; n=141), other ball games (OBG; n=42), other sports (OS; n=194), and no sports-club participation (NSC; n=167). The children completed a battery of health and fitness tests, including a 20 m sprint test, a standing long-jump test, the Yo-Yo IR1 children's test (YYIR1C), and body composition, blood pressure, resting heart rate (HR rest ), and the flamingo balance test. The children engaged in club-based ball games (FC and OBG) had higher (p<0.05) lean body mass than NSC (FC: 17.5 ± 2.9; OBG: 18.4 ± 2.6; OS: 16.7 ± 2.9; NSC: 16.4 ± 2.8 kg), performed better (p<0.05) in the YYIR1C test (FC: 1083 ± 527; OBG: 968 ± 448; OS: 776 ± 398; NSC: 687 ± 378 m), and had lower (p<0.05) %HR max after 1, 2, and 3 min of YYIR1C. Moreover, HR rest was lower (p<0.05) for FC than for OS and NSC (FC: 68 ± 9 vs OS: 72 ± 10 and NSC: 75 ± 10 bpm), and lower (p<0.05) for OBG than for NSC (OBG: 70 ± 10 vs NSC: 75 ± 10 bpm). This study found that 10-12-year-old Danish children engaged in club-based football and other ball games had better exercise capacity, lower resting heart rate, and higher muscle mass than children not engaged in leisure-time sports. Thus, participation in club-based leisure-time ball-game activities seems to be of importance for the fitness and health profile of prepubertal children.

Objective: The present study investigated the influence of exercise-specific motivation and volition on weight loss maintenance following an intensive lifestyle intervention (ILI)., Method: The study participants were 164 individuals with obesity (body mass index [BMI] > 30 kg/m2) that participated in an ILI. Participants' exercise-specific volition and motivation were assessed before and after the intervention as well as 3 and 12 months after completion. Volition was measured with the Volition in Exercise Questionnaire and motivation was measured with the context translated Sport Motivation Scale., Results: Mixed model analysis revealed that when adjusting for gender, age, and education, the 6 volitional scales and intrinsic motivation predicted BMI across the 4 time points, whereas 6 volitional scales and 2 extrinsic regulation scales showed a time interaction. Backward elimination multiple mixed model analysis revealed that Volitional Inhibition - Postponing Training and Volitional Facilitation - Self-Confidence predicted BMI development, whereas Volitional Inhibition - Unrelated Thoughts, Identified Regulation, and Introjected Regulation showed a time interaction above and beyond the other scales., Conclusion: Exercise-specific volition and motivation influence weight loss maintenance following an ILI. Volitional self-confidence and the tendency to postpone training are of importance above and beyond the previously identified predictor of autonomous exercise motivation. Results of the study also indicate that extrinsic motivation can be either facilitating or counterproductive depending on the level of self-determination.

Introduction: The aim of this study was to investigate the relationship between weight loss during and after a unique type of weight loss intervention, namely, a residential intensive lifestyle intervention (ILI), and participants' obesity-specific health-related quality of life (HRQOL) several years after the intervention. In the residential ILI under investigation, participants attended a 10- to 12-week long course away from their daily living environment, namely, at Ubberup Folk High School located in Denmark., Methods: A total of 79 former participants (31 male, mean age 36.6; SD = 12.7 years) who had participated in the intervention on average 5.3 (SD = 3.2) years ago were recruited for this study. They completed a questionnaire on weight-related quality of life (IWQOL-lite) and physical activity, as well as measurements of VO 2 max, blood pressure, Homeostatic Model Assessment for Insulin Resistance, waist circumference and hand grip strength., Results: The study results showed that weight change after the end of the intervention could predict HRQOL whereas how much weight they lost during the intervention could not. Furthermore, almost all of the investigated physiological factors were related to participants' current HRQOL. Waist circumference showed relationships with four of the five aspects of HRQOL., Conclusion: Focusing on behavioural change, adhering to improved lifestyle and maintaining weight loss after the end of the intervention seem to be the key not only for cardio-metabolic risk factors but also for sustainable HRQOL.

Aim: To modify the 'FIFA 11 for Health' programme to the European situation, and to assess its effects on health knowledge and well-being in Danish school children., Method: A two-cohort study with seven intervention and two control schools. Of the 546 Danish children (boys 269; girls 277) of mean age 11.1 (±0.4) years from five city and four country-side schools, 402 undertook the 'FIFA 11 for Health' programme and 144 acted as controls. As part of each school's PE curriculum, seven intervention schools received a 45 min Play Football period (football skills and 3 vs 3 games) and a 45 min Play Fair period (health issues and football drills) on a weekly-basis for 11 weeks. Control participants continued with their regular school PE activities. Participants completed preintervention and postintervention health knowledge and well-being questionnaires., Results: Overall, health knowledge increase was significantly (p<0.05) greater for the intervention group (11.9%) than the control group (2.6%). Significant (p<0.05) between-group differences were obtained for 8 of 10 health topics (6.1-20.2%) related to physical activity, nutrition, hygiene and well-being. The social dimension of the well-being questionnaire was significantly (p<0.05) improved in the intervention group compared to the control group, but there were no significant between-group effects for the physical, emotional and school dimensions. Positive reporting about the programme was given by 72.4% of the children and only 4.8% reported negatively., Conclusions: The 'FIFA 11 for Health' programme modified for Europe demonstrated positive effects on children's health knowledge and social dimension of well-being, thereby providing evidence that the football-based health education programme can be used effectively within a European school's curriculum to increase physical activity, well-being and health knowledge., (Published by the BMJ Publishing Group Limited.

Doping is increasingly becoming a problem in both elite and recreational sports. It is therefore important to understand the psychological factors which can explain doping behavior in order to prevent it. The present paper briefly presents evidence on the prevalence of doping use in competitive sports and the measurement approaches to assess doping behavior and doping-related variables. Furthermore, the integrative theoretical approaches used to describe the psychological processes underlying doping use are discussed. Finally, the paper provides suggestions for appropriate measurement of doping behavior and doping-related variables, key preventive efforts against doping as well as avenues for future research., (Copyright © 2017 Elsevier Ltd.

Aims: To investigate the relationship between volition, physical activity and weight loss maintenance., Methods: We recruited 84 sedentary (maximal oxygen uptake: 25 ± 5 ml/min), overweight and obese (Body mass index (BMI) 38 ± 7 m/h 2 , fat 44 ± 7 %) women ( n = 55) and men ( n = 29) for an interdisciplinary prospective study with follow-up. The change in lifestyle and weight loss is promoted via a 3-month intensive lifestyle intervention at a private health school. The intervention consists of supervised training (1-3 hours/day), a healthy hypo-caloric diet (-500 to -700 kCal/day) and education in healthy lifestyle in classes/groups. The participants' body weight and composition (Dual Energy X-ray absorptiometry), volitional skills (questionnaire), physical activity level (heart rate accelerometer/questionnaire) and maximal oxygen uptake (indirect calorimetry) are to be monitored before, after, and 3 and 12 months after the intervention., Results: At the 12-month follow-up, three different groups will be established: Clinical weight loss maintenance (> 10% weight loss from baseline), moderate weight loss maintenance (1-10% weight loss) and no weight loss (or weight regain). A linear mixed model analysis will be used to compare levels of volitional skills, physical activity and maximal oxygen uptake over time, between the three groups. Correlational analyses will be used to investigate possible associations between volition, maximal oxygen uptake, physical activity level and weight loss maintenance., Conclusions: If specific volitional skills are identified as predictors of adherence to physical activity and success in clinical weight loss maintenance, these can be trained in future intensive lifestyle interventions in order to optimize the success rate.

This study investigates the enjoyment and cohesion of school children participating in a school-based high-intensity physical activity (PA) intervention. Both enjoyment and cohesion have been found to be important factors for adherence to regular physical and sport activity, an important outcome of PA interventions. The sample consisted of 300 pupils (mean age: 9.3 years; 52.7% female) assigned to a team sport intervention, an individual sport intervention, or a control group for 10 months. The Physical Activity Enjoyment Scale and Youth Sport Environment Questionnaire were used to measure enjoyment and cohesion. The Yo-Yo IR1C test determined fitness improvements. Results showed that enjoyment and cohesion (social) measured at the beginning of the intervention significantly predict fitness improvements achieved after 10 months. No differing developmental effects over time could be found in the intervention groups with regard to cohesion and enjoyment when comparing them to the control group. However, enjoyment and cohesion (social) significantly decreased in the groups that performed individual sports. Team sports seem to be more advantageous for the development of enjoyment and cohesion, which are both factors that positively impact the health outcomes of the intervention.

From 4 to 7 April 2016, 24 researchers from 8 countries and from a variety of academic disciplines gathered in Snekkersten, Denmark, to reach evidence-based consensus about physical activity in children and youth, that is, individuals between 6 and 18 years. Physical activity is an overarching term that consists of many structured and unstructured forms within school and out-of-school-time contexts, including organised sport, physical education, outdoor recreation, motor skill development programmes, recess, and active transportation such as biking and walking. This consensus statement presents the accord on the effects of physical activity on children's and youth's fitness, health, cognitive functioning, engagement, motivation, psychological well-being and social inclusion, as well as presenting educational and physical activity implementation strategies. The consensus was obtained through an iterative process that began with presentation of the state-of-the art in each domain followed by plenary and group discussions. Ultimately, Consensus Conference participants reached agreement on the 21-item consensus statement., (Published by the BMJ Publishing Group Limited.

Background: Urine sample collection for doping control tests is a key component of the World Anti-Doping Agency's fight against doping in sport. However, a substantial number of athletes experience difficulty when having to urinate under supervision. Furthermore, it cannot always be ensured that athletes are actually delivering their own urine. A method that can be used to alleviate the negative impact of a supervised urination procedure and which can also identify urine as coming from a specific athlete is the urine marker test. Monodisperse low molecular weight polyethylene glycols (PEGs) are given orally prior to urination. Urine samples can be traced to the donor by analysis of the PEGs previously given., Objective: The objective of this study was to investigate the use of the urine marker during urine doping control testing., Methods: Two studies investigated athletes' acceptance of this new method via two questionnaires (n = 253). Furthermore, a third study (n = 91) investigated whether ingestion of the marker can identify the urine as coming from a specific person and whether the marker interferes with the detection of prohibited substances., Results and Conclusions: The results indicate that this new method finds wide acceptance both from athletes who have only heard about the procedure and those who have actually tested the new method. Furthermore, the marker, which can identify urine as coming from a specific person, does not interfere with the detection of prohibited substances.

The primary purpose of this study was to investigate the effect of the place of early development in a sample of Danish male elite and youth handball and football players. The sample included 366 handball and football players from the elite Danish league in the season 2011-2012 and a comparison sample of youth players under the age of 12 from 2003, including 147,221 football and 26,290 handball players. Odds ratio analysis showed that both population size and density significantly affected the proportional number of youth players per community and the odds of athletes reaching an elite level in football and handball. The odds for youth player registrations in both handball and football increased in rural in contrast to urban communities. However, elite football players primarily came from communities of high density (>1000 pop./km(2)), whereas elite handball players primarily came from less densely populated communities (100 to <250 pop./km(2)). Furthermore, there seems to be a relation between representation of elite and talent clubs in different communities and the probability of becoming an elite player in both sports. The limited number of elite players in both sports from rural communities may be due to national talent development strategies that do not incorporate development support for clubs in rural areas. Additionally, the results of the study clearly suggest the need to include the youth player population to advance research findings in birthplace effect studies.

This study investigated the effect of increased high-intensity interval training (HIT) at the expense of total training volume on the stress and recovery levels of elite swimmers. Forty-one elite swimmers participated in the study and were randomly assigned to either a HIT or a control group (CON). Eleven swimmers did not complete the questionnaires. For 12 weeks both groups trained ~12 h per week. The amount of HIT was ~5 h vs. 1 h, and total distance was ~17 km vs. ~35 km per week for HIT and CON, respectively. HIT was performed as 6-10 × 10-30 s maximal effort interspersed by 2-4 min of rest. The Recovery Stress Questionnaire - Sport was used to measure the swimmers' stress and recovery levels. After the 12 week intervention, the general stress level was 16.6% (2.6-30.7%; mean and 95% CI) lower and the general recovery level was 6.5% (0.7-12.4%) higher in HIT compared to the CON, after adjusting for baseline values. No significant effects could be observed in sports-specific stress or sports-specific recovery. The results indicate that increasing training intensity and reducing training volume for 12 weeks can reduce general stress and increase general recovery levels in competitive swimmers.

One of the fundamental challenges in anti-doping is identifying athletes who use, or are at risk of using, prohibited performance enhancing substances. The growing trend to employ a forensic approach to doping control aims to integrate information from social sciences (e.g., psychology of doping) into organised intelligence to protect clean sport. Beyond the foreseeable consequences of a positive identification as a doping user, this task is further complicated by the discrepancy between what constitutes a doping offence in the World Anti-Doping Code and operationalized in doping research. Whilst psychology plays an important role in developing our understanding of doping behaviour in order to inform intervention and prevention, its contribution to the array of doping diagnostic tools is still in its infancy. In both research and forensic settings, we must acknowledge that (1) socially desirable responding confounds self-reported psychometric test results and (2) that the cognitive complexity surrounding test performance means that the response-time based measures and the lie detector tests for revealing concealed life-events (e.g., doping use) are prone to produce false or non-interpretable outcomes in field settings. Differences in social-cognitive characteristics of doping behaviour that are tested at group level (doping users vs. non-users) cannot be extrapolated to individuals; nor these psychometric measures used for individual diagnostics. In this paper, we present a position statement calling for policy guidance on appropriate use of psychometric assessments in the pursuit of clean sport. We argue that, to date, both self-reported and response-time based psychometric tests for doping have been designed, tested and validated to explore how athletes feel and think about doping in order to develop a better understanding of doping behaviour, not to establish evidence for doping. A false 'positive' psychological profile for doping affects not only the individual 'clean' athlete but also their entourage, their organisation and sport itself. The proposed policy guidance aims to protect the global athletic community against social, ethical and legal consequences from potential misuse of psychological tests, including erroneous or incompetent applications as forensic diagnostic tools in both practice and research., (Copyright © 2015 Elsevier B.V.

A controversial question within elite sports is whether young athletes need to specialize early, as suggested by Ericsson et al., or if it is more beneficial to follow the path of early diversification proposed by Côté et al., which includes sampling different sport experiences during childhood and specializing later on during adolescence. Based on a Danish sample of 148 elite and 95 near-elite athletes from cgs sports (sports measured in centimeters, grams, or seconds), the present study investigates group differences concerning accumulated practice hours during the early stages of the career, involvement in other sports, career development, as well as determining whether or not these variables predict membership in the elite group. The results clearly reveal that elite athletes specialized at a later age and trained less in childhood. However, elite athletes were shown to intensify their training regime during late adolescence more than their near-elite peers. The involvement in other sports neither differs between the groups nor predicts success. It can be concluded that factors related to the organization of practice during the mid-teens seem to be crucial for international success within cgs sports. Future research should adopt a longitudinal design with means of drawing causal inferences., (© 2011 John Wiley & Sons A/S.)

This study explores whether inactive individuals can experience flow, a rewarding, psychological state, during an exercise intervention and if there are differences according to the type of intervention they perform. Furthermore, the study investigates if experiencing flow is connected to physiological improvements attained during the exercise intervention. The 12- to 16-week interventions included six randomized intervention groups, two female and four male groups performing continuous running, football, interval running and strength training. The results indicate that all six randomized exercise intervention groups experience rather high levels of flow regardless of whether the intervention is a team or individual sport. Differences in experiencing flow, worry and exertion as well as physiological improvements could be found for the different types of sports and the two genders, with the male football group having the highest score for physiological improvement and the lowest score for worry. A connection between experiencing flow and physiological improvement could not be found. Future research should investigate the influence that the participant's gender and also the type of sport have on experiencing flow, worry and perceived exertion. Furthermore, it should be investigated whether experiencing flow is linked to the long-term compliance of regular physical activity.
