Identity and motivation of adolescent student-athletes in school and elite sport: an investigation of the relationship within- and cross-domains
Introduction: Previous studies have highlighted the effects of motivation and identity on dual careers (DC) separately.Methods: The present study investigated the mutual relationship among 495 student-athletes (mean age = 17.0, males = 56.6%) in upper secondary school. The Student Identity Measurement Scale (SIMS), Academic Identity Measurement Scale (AIMS), and Student-Athletes’ Academic and Athletic Motivation Scale (SAAMS) were used in a cross-sectional design.Results: Findings revealed that student-athletes expressed higher identity than motivation within each domain. Athletic identification and motivation were stronger than those for academics. Correlation models revealed strong relations between identity and motivation within a domain, but not across domains. Gender differences emerged, with female student-athletes reporting higher academic identity and motivation compared to males.Discussion: The study supports the notion that balancing both academia and sports is vital to prevent identity foreclosure and enhance a successful DC. Additionally, the need for individualised support and talent identification strategies for student-athletes is emphasised.

Student–Athletes’ Academic and Athletic Motivation Scale (SAAMS) for adolescents in secondary school: development, evaluation, and psychometric properties
Previous dual-career (DC) research focused on measuring student–athletes’ motivation in the academic and athletic contexts. Existing measurement instruments are insufficient for adolescent student–athletes and countries with independent education and sport systems. The Student–Athletes’ Academic and Athletic Motivation Scale (SAAMS) was developed based on the expectancy–value framework (EVF) with its dimensions ability beliefs, expectations, importance, interest, usefulness, and cost. The development of the SAAMS followed three phases: (1) item development, (2) scale development, and (3) scale evaluation. The initial version was tested with 346 student–athletes (mean age = 17.3 years; females = 47.7%). A revision phase resulted in a final SAAMS tested with 497 student–athletes (mean age = 17.0 years; females = 42.9%). Exploratory and confirmatory factor analyses were conducted for the evaluation. Several models were tested with the best results for a six-factor model as assumed by the EVF. The SAAMS is suitable for an extensive range of research and practical applications.

Talented athletes as high achievers—only in sports? Analysis of academic performance and the impact of dual career assistance programmes in upper secondary school
The simultaneous pursuit of success in elite sport and the highest school qualification is considered to be one of the challenges for adolescents who are sporting talents. Dual career assistance programmes (DCAPs) for student-athletes are designed to help master this challenge in the best possible way. This study focusses on the upper secondary school performance of 200 student-athletes from an elite sports school. First, the school performance of student-athletes enrolled in two different DCAPs was compared. In addition to the educational services in DCAP‑1, DCAP‑2 includes a 1-year extension of the school period and the option of spreading the final exam phase out over several school years. Second, the school performance of student-athletes was compared with the performance of the entire student population. The analyses yielded the following findings: 1) student-athletes’ school performance is well above the average of the entire student population. 2) Although, DCAP‑2 users are much more involved in elite sport, their school performance and performance development do not differ from DCAP‑1 users. These results do not provide any indication of a systematic neglect of student-athletes’ academic career in favour of their athletic career. DCAPs appear to ensure the success of student-athletes’ academic careers effectively.

Does quantity make the difference? Associations between the amount of physical education and children’s basic motor competencies
Basic motor competencies (BMC) belong to the main learning goals of physical education (PE) in primary school and are needed to actively take part in the culture of sport and human movement. BMC levels between European countries differ widely and individual determinants like age, sex, and extracurricular physical activity participation consistently predict BMC levels (Wälti et al., 2022), but also structural aspects of PE are important factors of learning outcomes. In this study, we wanted to investigate if the weekly amount of PE accounts for differences in BMC levels across countries. We assessed BMC (object movement, self-movement), anthropometric data (sex, age, body-mass-index) and participation in extracurricular physical activity (ball sports, individual sports) in 3,069 6- to 10-year-old primary school children using the MOBAK-1-4 and structural aspects (amount of PE) in 179 teachers from eight European countries. Latent multilevel regression analyses were corrected for children’s sex, age, body-mass-index, extracurricular physical activity participation and region of assessment. Despite differences in the weekly amount of PE in the assessed samples, there were no significant associations between the amount of PE and object movement or self-movement in either the 6- to 8-year-old or the 8- to 10-year-old children. The covariates age, sex, body-mass-index and participation in ball sports were significant predictors of object movement in all children. Body-mass-index and participation in any kind of extracurricular physical activity were significantly associated with self-movement in children aged 6-8 years. In children aged 8-10 years, all anthropometric variables as well as participation in any kind of extracurricular physical activity were significant predictors of self-movement. Other country-specific or PE-related factors might be more crucial for the differences in BMC levels than the amount of PE (García-Hermoso et al., 2020). A focus on the quality and content of PE lessons as well as on the qualification and goals of PE teachers is suggested. Nevertheless, for children who do not participate in extracurricular physical activity, PE can be crucial for BMC development. References García-Hermoso, A., Alonso-Martínez, A.

Investigating levels and determinants of primary school children’s basic motor competencies in nine European countries
Basic motor competencies (BMC) belong to the key learning goals of Physical Education (PE) in primary school curricula in Europe. These competencies are necessary to participate in sports inside and outside of school. Children should therefore achieve age-adequate BMC in PE and any need for educational motor support should be identified at an early stage. Studies in German-speaking countries showed that various endogenous and exogenous factors are related to children’s BMC, but international studies are missing. In the present cross-sectional study, the two BMC areas object movement (OM) and self-movement (SM) as well as the associations with endogenous (age, sex, body mass index) and exogenous (participation in extracurricular sports) factors were investigated in 1721 8‑ to 10-year-old primary school children from nine European countries. Over 25% of the children showed need for educational motor support in OM and over 20% in SM. BMC levels differed significantly between the country-specific subsamples. In all subsamples, boys showed better performances in OM, while girls scored better in SM. Older children performed better in OM and SM than younger children. Higher body mass index predicted lower BMC scores in both competence areas. Participation in ball sports was positively associated with OM and SM, and individual sports participation was a significant predictor of SM. As exogenous and endogenous variables consistently predicted BMC in all subsamples, there must be other reasons for variation in BMC levels. Future studies should address country- and school-specific characteristics like content and amount of PE.

Measuring dual career motivation among German student-athletes using the Student Athletes’ Motivation Toward Sports and Academics Questionnaire
With the 2012 EU guidelines on dual careers (DC), DC research gained increasing awareness in Europe focussing particularly on student-athletes’ motivation. The Student Athletes’ Motivation toward Sports and Academics Questionnaire (SAMSAQ), arguably the most prominent instrument in this research area, has been used in various cross-cultural studies assessing DC motivation. The present investigation contributes to the cross-cultural discourse aiming to (1) adapt the SAMSAQ for the German context and adolescent secondary school student-athletes, and (2) evaluate the German pre-version. A sample of 208 student-athletes (52.4% females, mean age = 17.4 years, 49.5% at squad level) at three German Elite Sport Schools participated in the study. The investigation was split into two parts. First, the SAMSAQ was adapted to the German context and tested. In the second part, the first pre-version was revised. A series of exploratory factor analyses were applied to verify the factor structure of both German SAMSAQ pre-versions. Eight different factor models based on item removal were compared. Neither model demonstrated good results for the replication of previous findings or a meaningful solution in terms of content. Reasons for the deviations between the original and target SAMSAQ factor structures can be found in the different target groups and the culturally different approaches to career assistant programmes as well as in the theoretical background of the instrument. Since neither model was identified as acceptable, the findings indicate that a new instrument needs to be developed for assessing student-athletes’ DC motivation along their pathways in different cross-cultural contexts.

School Children’s Physical Activity, Motor Competence, and Corresponding Self-Perception: A Longitudinal Analysis of Reciprocal Relationships
Background: The relationship between engagement in physical activity and the development of motor competence (MC) is considered to be reciprocal and dynamic throughout childhood and adolescence. The 10-month follow-up study aimed to explore this reciprocal relationship and investigated whether the relationship is mediated by the corresponding self-perception of MC (PMC). Methods: A total of 51 children aged between 10 and 11 years (M = 10.27 [0.45]) participated in the study (52.9% boys, 47.1% girls). As an indicator for physical activity, the average vigorous physical activity (VPA) per day was measured by ActiGraph accelerometers. Two aspects of MC and PMC were recorded: self-movement and object movement. Saturated pathway models in a cross-lagged panel design with 2 measurement points were analyzed. Results: Reciprocal and direct relationships between VPA and MC object movement respectively MC self-movement were not found in longitudinal analyses with PMC as a mediator. Indirect effects of MC at t1 on VPA at t2 via PMC were identified (self-movement: β = 0.13, 95% confidence interval, 0.04 to 0.26; object movement: β = 0.14, 95% confidence interval, 0.01 to 0.49). Conclusion: The results highlight the importance of MC and PMC in promoting children’s VPA. However, VPA does not drive the development of MC.
