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. [ABSTRACT FROM AUTHOR]

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 VO2 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. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

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.

This article examines whether a training program in ethical decision making can change young athletes’ doping attitudes. Fifty-two young elite athletes were randomly assigned to either an ethical decision-making training group or a standard-knowledge-based educational program group. Another 17 young elite athletes were recruited for no-treatment control purposes. The ethical decision-making training comprised six 30-min online sessions in which the participants had to work through 18 ethical dilemmas related to doping. The standard-knowledge-based educational program was also conducted in six online sessions of comparable length to that of the ethical training. A short version of the Performance Enhancement Attitude Scale was administered to measure the effects of the trainings on doping attitude. Prior to as well as after the intervention, the mean doping attitude scores of the young athletes were low to very low, indicating vehement rejections of doping. The results of our experiment showed that the ethical training led to an attenuation of these rejections. No intervention effect was found in the standard education group. The observed slight increase in the doping attitude score could be an indication that the ethical decision-making training was successful in breaking up the athletes’ stereotypical style of reasoning about doping.

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. [ABSTRACT FROM AUTHOR]

In our study, we had two objectives. Our first objective was to test a social-cognitive model of doping in sport. In this model, we examined moral variables (i.e., moral disengagement, moral identity, anticipated guilt) and performance motivational climate as predictors of doping likelihood and whether performance motivational climate moderates the relationship between moral disengagement and doping likelihood. The second objective was to determine whether this model is invariant across sex and country. We used a cross-sectional design. Participants were 1495 (729 females) elite football players (mean age 20.4 ± 4.4) recruited from 97 teams in the UK, Denmark and Greece. They completed questionnaires measuring the aforementioned variables. Moral disengagement positively predicted doping likelihood both directly and indirectly via anticipated guilt. The direct relationship was significant only when performance climate was perceived as average or high. Moral identity negatively predicted doping likelihood via both moral disengagement and anticipated guilt; and performance climate positively predicted doping likelihood. The model was largely invariant across sex and country. Our findings suggest that young elite football players in the UK, Denmark and Greece are less likely to use banned substances to enhance their performance, if they consider being moral an important part of who they are, and if they perceive a low performance climate in their team. Moral identity is likely to trigger feelings of guilt associated with the use of banned substances and to mobilize moral disengagement mechanisms. Our findings highlight the importance of moral variables in deterring the use of banned substances in sport. • Young elite football players in the UK, Denmark and Greece are less likely to use banned substances if they consider being moral an important part of who they are. • When football players perceive a performance climate in their team they are more likely to use banned substances. • Performance climate may accentuate the facilitating role of moral disengagement on doping likelihood. • Moral identity is negatively associated with the use of banned substances via anticipated guilt. Moral identity could reduce the need to morally disengage leading to lower likelihood to dope. [ABSTRACT FROM AUTHOR]
