TY - JOUR A1 - Kahlert, Daniela A1 - Brand, Ralf T1 - Questionnaires for assessing physical activity different response scale categories influence responses concerning health- and sport-related cognitions JF - Zeitschrift für Gesundheitspsychologie N2 - The present study examines whether the use of different frequency scales in questionnaires about physical activity influences respondents' own estimation of their activity, as well as subsequent measurements of health- und sport-related cognitions and evaluations. Using a randomized research design we recruited a sample of 118 participants. One group received a high frequency scale for assessing their exercise frequency with the response categories "never", "less often", "once a month", "once a week", or "most days." The other group answered with a medium frequency scale with the alternatives "never", "less often", " once every few months", "once a month", and " once a week or more often." As dependent variables all participants judged the subjective importance of physical activity and their health-related quality of life (WHO-QOL-bref). Results indicate the expected response errors, owing to the fact that using a high-frequency scale produces higher levels of self-reported physical activity (Cramer's V = .30). Corresponding to this the subjective importance of physical activity increased (d = .37) and the health-related quality of life was judged to be better (d = .36). Such artefacts might be eliminated by using standardized formulations such as "I exercise... times per week/month for... minutes."

Das kindliche Bewegungsverhalten hat sich bereits im Grundschulalter verändert, so dass sich Bewegungsaktivitäten von Kindern erheblich unterscheiden und keineswegs mehr verallgemeinert werden können. Richtet man den Fokus auf die Frage „Wie bewegt sind unsere Kinder?“ so scheint diese von den Medien bereits beantwortet zu sein, da dort von ansteigendem Bewegungsmangel der heutigen Kinder gegenüber früheren Generationen berichtet wird. Wenn es in den Diskussionen um den Gesundheitszustand unserer Kinder geht, nimmt die körperlich-sportliche Aktivität eine entscheidende Rolle ein. Bewegungsmangel ist hierbei ein zentraler Begriff der in der Öffentlichkeit diskutiert wird. Bei der Betrachtung der einzelnen Studien fällt auf, dass deutliche Defizite in der Messung der körperlich-sportlichen Aktivität bestehen. Zentraler Kritikpunkt in den meisten Studien ist die subjektive Erfassung der körperlich-sportlichen Aktivität. Ein Großteil bisheriger Untersuchungen zum Bewegungsverhalten basiert auf Beobachtungen, Befragungen oder Bewegungstagebüchern. Diese liefern ausschließlich zum Teil subjektive Einschätzungen der Kinder oder Eltern über die tatsächliche Bewegungszeit und -intensität. Das objektive Erfassen der Aktivität bzw. Inaktivität ist zwar seit einigen Jahren zentraler Gegenstand vieler Studien, dennoch gilt es, dieses noch sachkundiger zu lösen, um subjektive und objektive Daten zu vergleichen. Um dem Bewegungsmangel der heutigen Kinder entgegenzuwirken, sind empirisch abgesicherte Erkenntnisse über die Bedingungsfaktoren und die Folgen des veränderten Bewegungsverhaltens dringend nötig. Die Quer- und Längsschnittuntersuchung umfasst die Bereiche Anthropometrie, die Erfassung der körperlich-sportlichen Aktivität und die Herzfrequenzmessung über 24h. Für die Studie konnten 106 Jungen und Mädchen im Zeitraum von Januar 2007 bis April 2009 rekrutiert und überprüft werden. Die physiologischen Parameter wurden mit Hilfe des ACTIHEART-Messsytems aufgezeichnet und berechnet. Die Ergebnisse zur körperlich-sportlichen Aktivität wurden in die Untersuchungsabschnitte Schulzeit gesamt, Pause, Sportunterricht, Nachmittag und 24h unterteilt. Durch das Messsystem werden die Bewegungsaktivität und die Herzfrequenz synchron aufgezeichnet. Das System nimmt die Beschleunigungswerte des Körpers auf und speichert sie im frei wählbaren Zeitintervall, Short oder Long Term, in Form von „activity counts“ ab. Das Messsytem berechnet weiterhin die Intensität körperlicher Aktivität. N2 - "Children's World is the world movement" (Schmidt, 1997, p. 156, quoted by Schmidt, Hartmann-Tews & Brettschneider, 2003, p. 31). The child's physical activity has changed already in elementary school, so that physical activity of children vary considerably and can not be more generalized. If we turn our focus to the question "What moves are our children?" So this seems to have been answered by the media, because there is increasing lack of physical activity reported by today's children from previous generations. When it comes to discussions about the health of our children, taking the physical and sporting activity plays a decisive role. Lack of exercise is a key term here is in the public's debate. When examining the individual studies is striking that significant deficiencies exist in the measurement of physical and sporting activity. The central point of criticism in most studies is the subjective detection of physical and sporting activity. A majority of previous studies on physical activity based on observations, interviews, or movement diaries. These provide only partly subjective assessments of the children or parents about the actual movement of time and intensity. The objective recording of activity or inactivity, although in recent years, the central subject of many studies, yet it is true, this knowledgeable yet to be resolved in order to compare subjective and objective data. To counteract the lack of movement of today's children, empirically based insights into the determinants and consequences of changes in physical activity are urgently needed. The cross-sectional and longitudinal study covers the areas of anthropometry, the collection of physical and sporting activity and heart rate measured over 24 hours. For the study, 106 boys and girls in the period January 2007 to April 2009 are being recruited and examined. The physiological parameters were recorded using the ACTIHEART-measuring systems and calculated. The results for physical and sporting activity were divided into the total school study sections, breaks, physical education, and 24 afternoon. By the measurement system's physical activity and heart rate recorded synchronously. The system records the acceleration of the body and stores it in the selected time interval, from Short or Long Term, in the form of "activity counts". The measurement system calculates the intensity of physical activity continue.

The MoMo-AFB consists of 28 items, covering the fields of everyday physical activity, sports within and outside of organised clubs, physical education as well as compliance with physical activity guidelines. A study was conducted with 109 boys and 87 girls aged between 9 and 17 years. The MoMo-AFB was given on two separate occasions to evaluate reliability and was compared with accelerometry data of ActiGraph GT1X to evaluate validity. The overall kappa/weighted kappa coefficient for the one-week testretest reliability was .66 (SD = .19) and the overall intraclass correlation (ICC) .68. Self-reported and accelerometer-measured average weekly time spent performing moderate to vigorous physical activity were significantly correlated (Spearman r = .29). Regarding reliability and validity, the MoMo-AFB is comparable with other international published physical activity questionnaires for adolescents.

It is established that overweight belongs to a global problem. In addition, German children exhibit a less robust skeleton than ten years ago. These developments may elevate the risk of cardiovascular diseases and skeletal modifications. Heredity and environmental factors as nutrition, socioeconomic status, physical activity and inactivity influence fat accumulation and the skeletal system. Based on these negative developments associations between type of body shape, skeletal measures and physical activity; relations between external skeletal robustness, physical activity and inactivity, BMI and body fat and also the progress of body composition especially external skeletal robustness in comparison in Russian and German children were investigated. In a cross-sectional study 691 German boys and girls aged 6 to 10 years were examined. Anthropometric measurements were taken and questionnaires about physical activity and inactivity were answered by parents. Additionally, pedometers were worn to determinate the physical activity in children. To compare the body composition in Russian and German children data from the years 2000 and 2010 were used. The study has shown that pyknomorphic individuals exhibit the highest external skeletal robustness and leptomorphic ones the lowest. Leptomorphic children may have a higher risk for bone diseases in adulthood. Pyknomorphic boys are more physically active by tendency. This is assessed as positive because pyknomorphic types display the highest BMI and body fat. Results showed that physical activity may reduce BMI and body fat. In contrast physical inactivity may lead to an increase of BMI and body fat and may rise with increasing age. Physical activity encourages additionally a robust skeleton. Furthermore external skeletal robustness is associated with BMI in order that BMI as a measure of overweight should be consider critically. The international 10-year comparison has shown an increase of BMI in Russian children and German boys. Currently, Russian children exhibit a higher external skeletal robustness than the Germans. However, in Russian boys skeleton is less robust than ten years ago. This trend should be observed in the future as well in other countries. All in all, several measures should be used to describe health situation in children and adults. Furthermore, in children it is essential to support physical activity in order to reduce the risk of obesity and to maintain a robust skeleton. In this way diseases are able to prevent in adulthood. N2 - Die Lebens- und Ernährungsweise sowie die Freizeitaktivitäten von Kindern haben sich im Laufe der letzten Jahre verändert. Daraus resultieren Veränderungen der Körperzusammensetzung. Es ist hinreichend bekannt, dass Übergewicht ein globales Problem ist. Des Weiteren weisen deutsche Kinder ein weniger robustes Skelett auf als noch vor 10 Jahren. Diese Entwicklungen können zu unterschiedlichen Erkrankungen des Herz-Kreislauf-Systems bzw. des Skelettsystems führen. Neben genetischen Faktoren haben Umweltfaktoren wie Ernährung, sozialer Status, die körperliche Aktivität bzw. Inaktivität einen Einfluss auf die Fettakkumulation und das Skelettsystem. Aufgrund der negativen Entwicklungen wurden daher die Zusammenhänge zwischen dem Körperbautyp, Skelettmaßen und der körperlichen Aktivität; die Beziehungen zwischen der äußeren Skelettrobustizität, der körperlichen Aktivität bzw. Inaktivität, dem BMI und dem Körperfettanteil sowie die Entwicklung der Körperzusammensetzung insbesondere die äußere Skelettrobustizität von russischen Kindern im Vergleich zu deutschen Kindern überprüft. In einer Querschnittstudie wurden 691 Jungen und Mädchen im Alter von 6 bis 10 Jahren aus Berlin und Brandenburg untersucht. Es wurden anthropometrische Messungen vorgenommen, Fragebögen bezüglich der sportlichen Aktivität und Inaktivität beantwortet sowie ein Schrittzähler zur Bestimmung der körperlichen Aktivität von den Kindern getragen. Für den internationalen Vergleich der Körperzusammensetzung wurden Daten aus den Jahren 2000 und 2010 von deutschen und russischen Kindern verwendet. Es konnte gezeigt werden, dass der pyknomorphe Körperbautyp die höchste und der leptomorphe Typ die niedrigste äußere Skelettrobustizität aufweisen. Leptomorphe Kinder könnten daher das höchste Risiko für Knochenerkrankungen im Erwachsenenalter aufweisen. Tendenziell zeigen pyknomorphe Jungen eine höhere körperliche Aktivität als die anderen Typen. Dies ist positiv zu bewerten, da die pyknomorphen Typen den höchsten BMI und Körperfettanteil besitzen. Wie die Resultate ergeben, kann die körperliche Aktivität zur Reduktion bzw. Inaktivität zur Erhöhung des BMIs und des Körperfettanteils führen. Die körperliche Inaktivität steigt mit zunehmendem Alter. Die körperliche Aktivität unterstützt weiterhin den Aufbau eines robusten Skeletts. Die äußere Skelettrobustizität ist ebenfalls positiv mit dem BMI assoziiert, so dass dargelegt werden konnte, dass der BMI als Maß für Übergewicht kritisch betrachtet werden sollte. Im internationalen 10-Jahresvergleich zeigt sich eine Zunahme des BMIs bei russischen Kindern und deutschen Jungen. Zurzeit weisen die russischen Kinder immer noch ein robusteres Skelett auf als die Deutschen jedoch ist das Skelett bei russischen Jungen weniger robust als noch vor 10 Jahren. Diese negative Entwicklung sollte weiterhin beobachtet werden auch in anderen Ländern. Alles in allem, sollten immer mehrere Maße zur Beschreibung des Gesundheitszustandes herangezogen werden. Weiterhin ist einer Förderung der körperlichen Aktivität bei Kindern notwendig, um zum einen das Risiko für Übergewicht zu minimieren und zum anderen ein robustes Skelett aufzubauen, um somit Erkrankungen im Erwachsenenalter vorzubeugen.

Thirteen children (10.1 (range 5.4-15.7)years, 3 girls) wore two accelerometers (ActiGraph GT3X+ (ACT), GENEA (GEN)) at the hip that provide raw acceleration signals at 100Hz. Participants completed different tasks (walking, jogging, running, landings from boxes of different height, rope skipping, dancing) on a force plate. GRF was collected for one step per trial (10 trials) for ambulatory movements and for all landings (10 trials), rope skips and dance procedures. Accelerometer outputs as peak loading (g) per activity were averaged. ANOVA, correlation analyses and Bland-Altman plots were computed to determine validity of accelerometers using GRF. There was a main effect of task with increasing acceleration values in tasks with increasing locomotion speed and landing height (P<0.001). Data from ACT and GEN correlated with GRF (r=0.90 and 0.89, respectively) and between each other (r=0.98), but both accelerometers consistently overestimated GRF. The new generation of accelerometer models that allow raw signal detection are reasonably accurate to measure impact loading of bone in children, although they systematically overestimate GRF.

Objective: The aim of this study was the explorative, nuanced determination of the interest in mHealth apps with respect to PA among students and staff of a university. Methods: We conducted a Web-based survey from June to July 2015 in which students and employees from the University of Potsdam were asked about their activity level, interest in mHealth fitness apps, chronic diseases, and sociodemographic parameters. Results: A total of 1217 students (67.30%, 819/1217; female; 26.0 years [SD 4.9]) and 485 employees (67.5%, 327/485; female; 42.7 years [SD 11.7]) participated in the survey. The recommendation for PA (3 times per week) was not met by 70.1% (340/485) of employees and 52.67% (641/1217) of students. Within these groups, 53.2% (341/641 students) and 44.2% (150/340 employees)—independent of age, sex, body mass index (BMI), and level of education or professional qualification—indicated an interest in mHealth fitness apps. Conclusions: Even in a younger, highly educated population, the majority of respondents reported an insufficient level of PA. About half of them indicated their interest in training support. This suggests that the use of personalized mobile fitness apps may become increasingly significant for a positive change of lifestyle.

Methods: A systematic search was performed to identify randomized controlled trials targeting adolescents (age: >= 10 years), conducted in the school setting, and reporting objectively measured physical activity. Random effects meta-analyses were conducted to determine the pooled effects of previous interventions on total and moderate-to-vigorous physical activity. Potential moderators of intervention effects were also explored. Results: Thirteen articles met the inclusion criteria, and twelve were included in the meta-analysis. The pooled effects were small and non-significant for both total physical activity (standardized mean difference = 0.02 [95% confidence interval = -0.13 to 0.18]) and moderate-to-vigorous physical activity (standardized mean difference = 0.24 [95% confidence interval = -0.08 to 0.56]). Sample age and accelerometer compliance were significant moderators for total physical activity, with a younger sample and higher compliance associated with larger effects. Conclusion: Previous school-based physical activity interventions targeting adolescents have been largely unsuccessful, particularly for older adolescents. There is a need for more high-quality research using objective monitoring in this population. Future interventions should comply with best-practice recommendations regarding physical activity monitoring protocols.

N2 - Introduction Though health-enhancing effects of physical activity are well documented, the majority of the population is unable to implement present recommendations into daily routine. Mobile health (mHealth) technologies might be able to increase the physical activity level. However, the interest of potential users is a mandatory basis for this. Method We conducted an online-survey from 06-07/2015 by asking students and employees from the University of Potsdam for their activity level, interest in mHealth training support and other relevant parameters. Results 1 217 students and 485 employees (67.3 % and 67.5 % female, 26.0 +/- 4.9 and 42.7 +/- 11.7 years, respectively) participated in the survey. 70.1 % of employees and 52.7 % of students did not follow the recommendation for physical activity (3 times per week). 53.2 % (students) and 44.2 % (employees), independent of age, sex, BMI and level of education or professional qualification, indicated their interest in mHealth technology offering training support. Conclusion Even in a younger population with higher education, most respondents reported an insufficient level of physical activity. About half of them indicated their interest in training support. Therefore, the use of personalized mHealth technology may be of increasing significance for a positive change of lifestyle.

T1 - Influence of the A/T polymorphism of the FTO gene and sport specializations on the body composition of young Russian athletes JF - Journal of biological and clinical anthropology : Anthropologischer Anzeiger ; Mitteilungsorgan der Gesellschaft für Anthropologie N2 - Background: The polymorphism in FTO gene (rs9939609) is known to be associated with higher BMI and body fat mass content. However, environmental factors can modify this effect. The purpose of the present study was to investigate an association between sport specialization and the rs9939609 SNP in FTO gene in the cohort of professional and amateur young athletes. Methods: A total number of 250 young individuals 8-18 years old living in Moscow or Moscow district participated in the study. Individuals were divided into 3 groups in accordance with their physical activity level: control group (n = 49), amateurs (n = 67) and professionals (n = 137). Amateur and professional athletes were subdivided into groups according to their sport specialization. Quantile regression was used as a regression model, where the dependent (outcome) variable was BMI, along with percentage of body fat mass, and the independent variables (predictors) were the rs9939609 SNP in FTO gene, physical activity (active versus inactive), sport specialization (aerobic, intermittent sports and martial arts), nationality, level of sport experience (in years), gender and percentage of free fat mass content. Results: The regression analysis revealed that physical activity and sport specialization had greater impact compared to FTO allele in the group of physically active individuals. Physical activity, in particular aerobic, had negative associations with body fat mass and BMI. The rs9939609 SNP in FTO gene is associated with physical activity and aerobic activity. The magnitude of association becomes significantly larger at the upper quantiles of the body fat mass distribution. Conclusion: Physical activity and sport specialization explained more variance in body composition of physically active young individuals compared to the FTO polymorphism. Effect of interaction of physical activity, in particular aerobic, with the FTO polymorphism on body composition of young athletes was found.

T1 - Physical activity protects from incident anxiety: A meta-analysis of prospective cohort studies JF - Depression and anxiety N2 - Background Prospective cohorts have suggested that physical activity (PA) can decrease the risk of incident anxiety. However, no meta-analysis has been conducted. Aims To examine the prospective relationship between PA and incident anxiety and explore potential moderators. Methods Searches were conducted on major databases from inception to October 10, 2018 for prospective studies (at least 1 year of follow-up) that calculated the odds ratio (OR) of incident anxiety in people with high PA against people with low PA. Methodological quality was assessed using the Newcastle-Ottawa Scale (NOS). A random-effects meta-analysis was conducted and heterogeneity was explored using subgroup and meta-regression analysis. Results Across 14 cohorts of 13 unique prospective studies (N = 75,831, median males = 50.1%) followed for 357,424 person-years, people with high self-reported PA (versus low PA) were at reduced odds of developing anxiety (adjusted odds ratio [AOR] = 0.74; 95% confidence level [95% CI] = 0.62, 0.88; crude OR = 0.80; 95% CI = 0.69, 0.92). High self-reported PA was protective against the emergence of agoraphobia (AOR = 0.42; 95% CI = 0.18, 0.98) and posttraumatic stress disorder (AOR = 0.57; 95% CI = 0.39, 0.85). The protective effects for anxiety were evident in Asia (AOR = 0.31; 95% CI = 0.10, 0.96) and Europe (AOR = 0.82; 95% CI = 0.69, 0.97); for children/adolescents (AOR = 0.52; 95% CI = 0.29, 0.90) and adults (AOR = 0.81; 95% CI = 0.69, 0.95). Results remained robust when adjusting for confounding factors. Overall study quality was moderate to high (mean NOS = 6.7 out of 9). Conclusion Evidence supports the notion that self-reported PA can confer protection against the emergence of anxiety regardless of demographic factors. In particular, higher PA levels protects from agoraphobia and posttraumatic disorder.

This systematic review summarizes the evidence for gene-lifestyle interactions regarding T2D incidence. MEDLINE, EMBASE, and Web of Science were systematically searched until 31 January 2019 to identify publication with (a) prospective study design; (b) T2D incidence; (c) gene-diet, gene-physical activity, and gene-weight loss intervention interaction; and (d) population who are healthy or prediabetic. Of 66 eligible publications, 28 reported significant interactions. A variety of different genetic variants and dietary factors were studied. Variants at TCF7L2 were most frequently investigated and showed interactions with fiber and whole grain on T2D incidence. Further gene-diet interactions were reported for, eg, a western dietary pattern with a T2D-GRS, fat and carbohydrate with IRS1 rs2943641, and heme iron with variants of HFE. Physical activity showed interaction with HNF1B, IRS1, PPAR gamma, ADRA2B, SLC2A2, and ABCC8 variants and weight loss interventions with ENPP1, PPAR gamma, ADIPOR2, ADRA2B, TNF alpha, and LIPC variants. However, most findings represent single study findings obtained in European ethnicities. Although some interactions have been reported, their conclusiveness is still low, as most findings were not yet replicated across multiple study populations.

A total of 491 older people (M = 72.68 years; SD = 5.47) attending a health exercise program participated in this study. Cronbach's alpha was found to be high (alpha = .90). Satisfaction with the exercise professional correlated moderately with the short Health Care Climate Questionnaire mean value (r = .38; p < .01). The mediator analyses yielded support for the self-determination theory process model in older adults by showing both basic need satisfaction and frustration as mediating variables between perceived autonomy support and depressive symptoms. The short Health Care Climate Questionnaire is an economical instrument for assessing basic need satisfaction provided by the exercise therapist from the participant's perspective. Furthermore, this cross-sectional study supported the link from coaching style to the satisfaction/frustration of basic psychological needs, which in turn, predicted mental health. Analyses of criterion validity suggest a revision of the construct by integrating need frustration.

Neben der medikamentösen Blutdruck- und Lipideinstellung auf leitlinienorientierte Zielwerte ermöglichen moderne Antidiabetika eine Optimierung des glukometabolischen Kontinuums und eine Prognosebesserung. Die Lebensstiloptimierung setzt sich aus koronarprotektiver Ernährung, einer individualisierten Trainingstherapie, einer konsequenten Nikotinkarenz und stressreduzierenden Maßnahmen zusammen. Die kardiologische Rehabilitation (Phase II) schließt sich idealerweise unmittelbar einem stationären Aufenthalt wegen eines akuten Koronarereignisses an, kann aber auch im Rahmen einer stabilen Koronarsituation im Rahmen eines allgemeinen Antragsverfahrens durchgeführt werden. Randomisierte und prospektiv angelegte Interventionsstudien belegen die prognostische Wertigkeit der kardiologischen Rehabilitation auch im Zeitalter akuter Revaskularisationstherapie mit 24-h-PCI und moderner Pharmakotherapie. N2 - Secondary prevention of coronary artery disease includes pharmacological and lifestyle-based therapy that ideally interact and potentiate. In addition to blood pressure and lipid adjustment to guideline-oriented target values, modern antidiabetic agents enable an optimization of the glucometabolic continuum and improve prognosis. Lifestyle optimization consists of coronary protective nutrition, individualized training therapy, consistent nicotine withdrawal and stress-reducing measures. Cardiological rehabilitation (phase II) ideally immediately follows an inpatient stay due to an acute coronary event, but can also be carried out in the context of a stable coronary situation. Randomized and prospective intervention studies prove the prognostic value of cardiological rehabilitation even in the age of acute revascularization therapy with 24-hour PCI and modern pharmacotherapy.

We used the brief window of global lockdown in the months of March/April/May 2020 as an opportunity to investigate the effects of externally imposed restrictions on exercise-related routines and related changes in subjective well-being. Statistical analyses are based on data from 13,696 respondents in 18 countries using a cross-sectional online survey. A mixed effects modeling approach was used to analyze data. We tested whether exercise frequency before and during the pandemic would influence mood during the pandemic. Additionally, we used the COVID-19 pandemic data to build a prediction model, while controlling for national differences, to estimate changes in exercise frequency during similar future lockdown conditions depending on prelockdown exercise frequency. According to the prediction model, those who rarely exercise before a lockdown tend to increase their exercise frequency during it, and those who are frequent exercisers before a lockdown tend to maintain it. With regards to subjective well-being, the data show that those who exercised almost every day during this pandemic had the best mood, regardless of whether or not they exercised prepandemic. Those who were inactive prepandemic and slightly increased their exercise frequency during the pandemic, reported no change in mood compared to those who remained inactive during the pandemic. Those who reduced their exercise frequency during the pandemic reported worse mood compared to those who maintained or increased their prepandemic exercise frequency. This study suggests that under similar lockdown conditions, about two thirds of those who never or rarely exercise before a lockdown might adopt an exercise behavior or increase their exercise frequency. However, such changes do not always immediately result in improvement in subjective well-being. These results may inform national policies, as well as health behavior and exercise psychology research on the importance of exercise promotion, and prediction of changes in exercise behavior during future pandemics.

T1 - The Long-Run Effects of Sports Club Vouchers for Primary School Children T2 - CEPA Discussion Papers N2 - Starting in 2009, the German state of Saxony distributed sports club membership vouchers among all 33,000 third graders in the state. The policy’s objective was to encourage them to develop a long-term habit of exercising. In 2018, we carried out a large register-based survey among several cohorts in Saxony and two neighboring states. Our difference-in-differences estimations show that, even after a decade, awareness of the voucher program was significantly higher in the treatment group. We also find that youth received and redeemed the vouchers. However, we do not find significant short- or long-term effects on sports club membership, physical activity, overweightness, or motor skills.
