The coordination of body limbs and the timing during performing of a Baseball-pitch and its different movement phases are relatively unknown. The purpose of the present study was to describe and compare the coordination between the shoulder-elbow joints and timing during execution of a Baseball-pitch by skilled and unskilled subjects emphasizing movement phases. The subjects consisted of a skilled male pitcher and eight beginner pitchers. Intra-limb coordination was obtained for the shoulder-elbow joints and was shown by angle-angle plots. Start and end points of all pitchers were normalized by linear interpolation method to 250 points. Timing, angles of the beginning and end of each phase, and the minimum and maximum angles of shoulder and elbow joints in each phase were compared between skilled and unskilled pitchers. The results indicated that there is a relatively clear difference in the coordination patterns between the joints of the shoulder-elbow, especially in the first and second phases between skilled and unskilled pitchers. There were also many differences between unskilled pitchers with the skilled pitcher at the beginning and end as well as the minimum and maximum angles of shoulder and elbow joints in different phases. Considering the timing variable, the time of performing the whole movement and the first, fourth, and fifth phases in unskilled pitchers was significantly shorter than that of the skilled pitcher. The results were discussed with regard to spatiotemporal characteristics of the performing Baseball-pitch in skilled and unskilled pitchers. Also, were discussed practical considerations for improving skills and preventing injury. [less ▲]

L'examen systématique des compétences des élèves prend de plus en plus d'impor-tance dans le domaine de l'éducation. Dans le domaine de l'éducation à la motricité, l'approche MOBAK (Motorische Basiskompetenzen) s'est imposée dans l'évaluation des compétences motrices de base. Les outils de test MOBAK, développés pour la classe de première (cycle 2.1) et la classe de troisième (cycle 3.1) par l'Université du Luxembourg sur mandat du SCRIPT, sont régulièrement utilisés sur une base volontaire au niveau national depuis l'année scolaire 2014/2015. Les résultats de ces enquêtes montrent qu'environ un tiers des élèves du Luxembourg a besoin de soutien dans au moins une compétence motrice. Les filles réussissent moins bien que les garçons, en particu-lier dans le domaine « Manipulation d'un objet ». [less ▲]

At the 12th FIEP European Congress in Luxembourg, leading researchers and educationalists from all over Europe and beyond addressed current challenges and developments in the field of physical education. The present book includes contributions from all keynote speakers, as well as from the invited symposia hosted by international umbrella organizations, such as FIEP, the International Council of Sport Science and Physical Education (ICSSPE), the European Physical Education Association (EUPEA), the European Primary Physical Education Network (EPPEN) or the International Federation for Adapted Physical Activity (IFAPA). Furthermore, selected contributions to the parallel oral sessions and the FIEP New Leaders Program were included. All the contributions focus on the following congress key topics: • Physical Education in Early Childhood and Primary Education • Physical Education in Secondary Education • Physical Literacy • Physical Education Teacher Education • Physical Education and Physical Activity in Active School Communities • Intercultural Learning and Inclusion in Physical Education • Physical Education and New Technologies [less ▲]

Founded in 1923 in Brussels, the Fédération Internationale d'Éducation Physique (FIEP) is an independent and globally engaged organization, aimed at promoting a broad range of activities in the fields of physical education, sport for all, fitness and health, and recreation for people of all ages. It provides a network of contacts and a means of communication and exchange amongst scientists and organizations. <br /> <br />At the 12th FIEP European Congress in Luxembourg, leading researchers and educationalists from all over Europe addressed current challenges and developments in the field of physical education, for example, the physical activity behavior of young people, intercultural learning and inclusion and the use of digital technologies.

Das Konzept der Bewegten Schule geht auf den Schweizer Pädagogen Urs Illi zurück, der es Mitte der achtziger Jahre vor allem für den Primarbereich entwickelte (Illi, 1995). Ausgehend von einer medizinisch-gesundheitlichen (Bewegung als Gesundheitsressource) und entwick-lungs- und lerntheoretischen (Bewegung als zentrales Element der Kindesentwicklung, Bewe-gung als zusätzlicher Sinnes- und Erfahrungskanal) Begründung, geht es in diesem Konzept grundsätzlich darum, mehr Bewegung in die traditionelle „Sitzschule“ zu bringen. Am Projekt „Bewegter Unterricht in Luxemburg“ nahmen die SchülerInnen und Lehrkräfte der Grundschulen in Angelsberg, Larochette, Nommern, Lintgen und Vichten teil. An den Schulen Angelsberg, Larochette und Nommern fand im Untersuchungszeitraum von September 2014 bis Juni 2016 durchgehend Bewegter Unterricht statt. Diese Schulen werden im Weiteren als „Projektschulen“ bezeichnet. An den Schulen in Lintgen und Vichten wurde nicht „bewegt“ unterrichtet; diese Schulen dienten somit als Kontrollschulen. [less ▲]

Traditionally, motor learning scientists have evaluated the process of learning a new motor skill by considering the skill as a whole. Yet, motor skills comprises various phases, and in the motor learning literature, it is not clear whether new learner show similar or different learning across various phases. We provide exploratory data on learning movement phases by novices, using baseball pitching as the learning task. Eight participants (four male, four female, M age ¼ 23.7 years, SD ¼ 2.4) performed five trials each in the pretest followed by three blocks of 10 trials each in the acquisition phase. Finally, two retention tests of five trials were conducted by each participant 10 minutes and 7 days after the last acquisition block, respectively. Intraand interlimb coordination of upper and lower body segments were measured as dependent variables. We found significant differences between the stride phase and the other phases at pretest, during the acquisition phase, and on both retention tests across all kinematic variables. Participants experienced more trouble coordinating the stride phase than the other phases of pitching, perhaps because the stride phase is the only phase in which the participants had to move their upper and lower body parts simultaneously. We discuss implications for motor learning generally. [less ▲]
