TY - JOUR A1 - Sallen, Jeffrey A1 - Hemming, Karen A1 - Richartz, Alfred T1 - Facilitating dual careers by improving resistance to chronic stress BT - effects of an intervention programme for elite student athletes JF - European journal of sport science : official journal of the European College of Sport Science N2 - The starting point of this contribution is the potential risk to health and performance from the combination of elite sporting careers with the pursuit of education. In European sport science and politics, structural measures to promote dual careers in elite sports have been discussed increasingly of late. In addition to organisational measures, there are calls for educational-psychological intervention programmes supporting the successful management of dual careers at the individual level. This paper presents an appropriate intervention programme and its evaluation: stress-resistance training for elite athletes (SRT-EA). It comprises 10 units, each lasting 90 minutes. It is intended for athletes and aims to improve their resistance to chronic stress. The evaluation was carried out in a quasi-experimental design, with three points of measurement (baseline, immediately after, and three months after) and two non-randomised groups: an intervention group (n=128) and an untreated control group (n=117). Participants were between 13 and 20 years of age (53.5% male) and represented various Olympic sports. Outcome variables were assessed with questionnaires. Significant short- and mid-term intervention effects were explored. The intervention increased stress-related knowledge, general self-efficacy, and stress sensitivity. Chronic stress level, stress symptoms, and stress reactivity were reduced. In line with the intention of the intervention, the results showed short- and mid-term, small to medium-sized effects. Accordingly, separate measurements at the end of the intervention and three months later showed mostly positive subjective experiences. Thus, the results reinforce the hope that educational-psychological stress-management interventions can support dual careers.

The availability of low-cost camera hardware on the market today and recent advances in Machine Learning enable a wide range of clinical and health-related applications, such as patient monitoring or exercise recognition at home. In this study, we evaluated the motion tracking performance of the latest generation of the Microsoft Kinect camera, Azure Kinect, compared to its predecessor Kinect v2 in terms of treadmill walking using a gold standard Vicon multi-camera motion capturing system and the 39 marker Plug-in Gait model. Five young and healthy subjects walked on a treadmill at three different velocities while data were recorded simultaneously with all three camera systems. An easy-to-administer camera calibration method developed here was used to spatially align the 3D skeleton data from both Kinect cameras and the Vicon system. With this calibration, the spatial agreement of joint positions between the two Kinect cameras and the reference system was evaluated. In addition, we compared the accuracy of certain spatio-temporal gait parameters, i.e., step length, step time, step width, and stride time calculated from the Kinect data, with the gold standard system. Our results showed that the improved hardware and the motion tracking algorithm of the Azure Kinect camera led to a significantly higher accuracy of the spatial gait parameters than the predecessor Kinect v2, while no significant differences were found between the temporal parameters. Furthermore, we explain in detail how this experimental setup could be used to continuously monitor the progress during gait rehabilitation in older people.

Die Forschungsarbeit entstand aus der wachsenden Erkenntnis heraus, dass es nicht mehr nur um die Entwicklung und Durchführung kommunaler oder sozialer Projekte geht, sondern zunehmend darauf ankommt, die Projektarbeit zu evaluieren, um ihren Einfluss auf die kommunale, soziale und personale Entwicklung zu prüfen und in der Folge die Implementierung zu optimieren. Die unterschiedlichen Schritte in der Definition des theoretischen Rahmens, der Datenanalyse sowie der Erarbeitung der evaluativen Empfehlungen wurden unternommen mit dem Anspruch auf Modellcharakter, um für zukünftige Evaluationsvorhaben entsprechende Standards zu setzen. Die Grundidee des kommunalen Sportprojekts „Straßenfußball für Toleranz“ ist innovativ: Mädchen und Jungen erobern durch gemeinsames Fußballspielen den öffentlichen Raum. Sie spielen ohne Schiedsrichter und nach speziellen Regeln. Das Projekt richtet sich ausdrücklich an sozial benachteiligte Jugendliche und bezieht gleichermaßen Jungen wie Mädchen ein. N2 - The objective of the study is the evaluation of a community sports project. The thesis originated from the growing perception that it is not only about initiating and implementing a communal or social project but that the focus is increasingly also on the evaluation of the project work in order to measure its impact on communal, social and personal development and to optimise the implementation as a consequence. The different steps in the definition of the theoretical framework, the data analysis as well as the formulation of the evaluative recommendations were conducted with the pretension to set standards for future evaluation projects. The basic concept of the community sports project “Street Football for Tolerance” is innovative: boys and girls jointly conquer public spaces by playing football. They play without a referee and according to special rules. The project explicitly reaches out to socially disadvantaged adolescents, with the aim that boys and girls are equally involved.

Method: We examined the relation between creative and intuitive decision making in two studies-one involving coaches and one involving soccer players-using video footage of real soccer matches. Additionally, we analyzed whether this relation is culture generic or culture specific by conducting matched cross-cultural studies in a European and a South American country. Results: In Study 1, results indicate a conceptual overlap of creativity and intuition for Brazilian and German soccer coaches. Furthermore, coaches did not differ in their evaluation of creative and intuitive actions of players of both cultures. In Study 2, we found that for both subsamples the total number of generated options was positively correlated with the quality of the first and the final option and that the quality of players' first (intuitive) option was higher than that of options generated later. Moreover, results indicate a positive correlation between a player's creativity score and the quality of the first generated option for the whole sample. Conclusion: Overall, our findings provide meaningful information regarding athletes' and coaches' option-generation processes in decision making in complex team sports.
