Identifying profiles of actual and perceived motor competence among adolescents: associations with motivation,physical activity,and sports participation

The present study identified adolescents’ motor competence (MC)-based profiles (e.g., high actual and low perceived MC), and accordingly investigated differences in motivation for physical education (PE), physical activity (PA) levels, and sports participation between profiles by using regression analyses. Actual MC was measured with the Körperkoordinationstest für Kinder. Adolescents (n = 215; 66.0% boys; mean age = 13.64 ± .58 years) completed validated questionnaires to assess perceived MC, motivation for PE, PA-levels, and sports participation. Actual and perceived MC were only moderately correlated and cluster analyses identified four groups. Two groups of overestimators (low – overestimation, average – overestimation) were identified (51%), who particularly displayed better motivation for PE when compared to their peers who accurately estimated themselves (low – accurate, average – accurate). Moreover, adolescents with low actual MC, but high perceived MC were significantly more active than adolescents with low actual MC who accurately estimated themselves. Results pointed in the same direction for organised sports participation. Underestimators were not found in the current sample, which is positive as underestimation might negatively influence adolescents’ motivation to achieve and persist in PA and sports. In conclusion, results emphasise that developing perceived MC, especially among adolescents with low levels of actual MC, seems crucial to stimulate motivation for PE, and engagement in PA and sports.     

Les repre´sentations des futurs enseignants que´becois du primaire au regard de la formation initiale et des responsabilite´s des formateurs

Dans cet article, nous faisons état des résultats d'une recherche menée auprès des divers intervenants du processus de formation initiale à l'enseignement préscolaire et primaire à l'Université de Sherbrooke. L'objectif de la recherche était de dégager les représentations sociales des diverses catégories d'intervenants au regard des concepts de compétence, de pédagogie et de didactique, ainsi que sur la place et les fonctions attribuées par les étudiants aux différents types de formateurs. Les résultats suggèrent que les étudiants ont des positions beaucoup plus rapprochées de celles des enseignants du primaire que de celles des formateurs universitaires. Ils montrent également plusieurs distinctions quant à l'attribution des compétences de formation aux divers types d'intervenants et quant aux lieux privilégiés de formation. Ces constats soulignent l'importance d'établir un dialogue plus étroit entre les divers partenaires de la formation initiale des futurs enseignants. In this paper, we present various results of a piece of research undertaken with different partners involved in the teacher education programme offered by the University of Sherbrooke (Canada). The main purpose of the research was to identify the place and role that should be taken by various categories of trainer. Our results suggest that students align their behaviour far more closely to that of serving teachers than they do to those of academics. Results also reveal many distinctions between students' categories about what are the specific competencies of the trainers as well as what is the best training context. These results confirm the importance that should be given to improving dialogue between the various partners in programmes of teacher education. En este artículo tratamos de los resultados de una investigación realizada con los varios actores del proceso de formación inicial docente al preescolar y al primario en la Universidad de Sherbrooke. El objectivo central de esta investigación era de indicar las representaciones sociales de dichas categorías de actores a propósito de los conceptos de competencia, de pedagogía y de didáctica, asíque el lugar y la función atribuida, de parte de los estudiantes, a las varias categorias de formadores. Segun los resultados de la investigación, las representaciones de los estudiantes quedan mucho mas cercanas de aquellas compartidas por los docentes del medio (preescolar y primario) que de las representaciones de los docentes universitarios. Se notan también muchas diferencias en terminos de reconocimiento de unas competencias a la formación y de lugares de formación mas importantes atribuidas a las varias categorias de formadores. Estos logros van en el sentido de mejorar el diálogo entre los varios partenarios de la formación de los docentes. In diesem Artikel stellen wir die Ergebnisse einer wissenschaftlichen Forschungsarbeit gegenüber verschiedener Intervenienten im Entwicklungsprozess der Grundausbildung in der Kindergartenausbildung sowie in der Grundschulausbildung auf der Universität von Sherbrooke vor. Vorhaben dieser Forschung war es die sozialen Vorstellungen der verschiedenen Kategorien von Interventienten gegenüber der Vorstellung von Kompetenz, Pädagogik und Didaktik, sowie die Stellung und Funktion verschiedener Ausbildungstypen hervorzuheben. Die Ergebnisse lassen darauf schliessen dass der Standpunkt der Studenten näher an den der Grundschullehrer herankommt als an den der Universitätsausbilder. Sie zeigen auch grundlegende Unterschiede in der Zuteilung der Kompetenzen der Ausbildung in den verschiedenen Interventionstypen sowie in den bevorteiligten Ausbildungsorten. Diese Feststellung unterstreicht die Wichtigkeit eines engeren Dialogs zwischen den verschiedenen Partnern der Grundausbildung des zukünftigen Lehrpersonals.     

Formation à l'enseignement et interdisciplinarité: Un mythe ou une exigence? Dépasser l'interdisciplinarité et penser circumdisciplinarité

L'article a pour objectifs de discuter des rapports existant entre le système des disciplines scientifiques et la formation à l'enseignement conçue dans une perspective de professionnalisation. Après un rapide rappel historique du processus d'inféodisation de la formation professionnelle par le système des sciences, l'article introduit une distinction entre l'interdisciplinarité en éducation et l'interdisciplinarité scientifique. Il met en exergue, à la suite de ce double éclairage, la complexité des interrelations entre les différents types de savoirs dans un contexte de formation professionnelle à l'enseignement et la nécessité de dépasser les perspectives interdisciplinaires pour prendre en compte la circumdisciplinarité, c'est-à-dire l'insertion des savoirs qui résultent des pratiques professionnelles elles-mêmes au sein même de la formation. This paper discusses the existing relationships between the scientific subject matter system and teacher education from a professionalisation perspective. After a brief historical reminder of how professional training was subjugated by the scientific system, we introduce a distinction between interdisciplinarity in education and scientific interdisciplinary. The article then highlights the complexity of interrelationships between different types of knowledge, in a context of the professional training that is teacher education, and the necessity of going beyond interdisciplinary perspectives in order to take into account the circumdisciplinarity, which means the integration of knowledge that results from the very professional practice that is at the center of the teacher education. El objetivo central de este articulo es el de discutir de las relaciones entre el sistema de las disciplinas científicas y la formación a la enseñanza, dentro de una perspectiva de profesionalización. Después de una breve descripción del proceso histórico que llevó a la sumisión de la formación profesional al sistema de las ciencias, se introduce una distinción entre los conceptos de la interdisciplinaridad en la educación y la interdisciplinaridad científica. Se subraya el carácter complejo de las interrelaciones entre varios tipos de conocimientos dentro de un contexto de formación profesional a la enseñanza y de la necesidad de ir mas allá de las perspectivas interdisciplinarias para tomar en cuenta la circumdisciplinaridad. Este ultimo concepto suele significar la integración de los conocimientos o de los conocimientos que resultan de las prácticas profesionales en se, dentro del proceso de formación. Dieser Artikel untersucht die bestehenden Beziehungen zwischen den wissenschaftlichen Disziplinen und der Lehrerausbildung mit einer Professionalisierungsperspektive. Nach einem kurzen historischen Rückblick, wie das System der Berufsausbildung durch das Wissenschaftssystem geprägt wurde, unterscheidet der Artikel zwischen der Interdisziplinarität in der Lehrerausbildung und der in den Wissenschaften. Nach dieser Unterscheidung hebt er die Komplexität der Verhältnisse verschiedener Wissenstypen in einem Kontext der Berufsausbildung hervor, sowie die Notwendigkeit interdiziplinäre Perspektiven zu überschreiten, um die Zirkumsdiziplinarität zu berücksichtigen, das heißt, das Wissen, das sich aus der Praxis ergibt, in die Lehrerbildung einzubeziehen.     

Predictive models reduce talent development costs in female gymnastics

This retrospective study focuses on the comparison of different predictive models based on the results of a talent identification test battery for female gymnasts. We studied to what extent these models have the potential to optimise selection procedures, and at the same time reduce talent development costs in female artistic gymnastics. The dropout rate of 243 female elite gymnasts was investigated, 5 years past talent selection, using linear (discriminant analysis) and non-linear predictive models (Kohonen feature maps and multilayer perceptron). The coaches classified 51.9% of the participants correct. Discriminant analysis improved the correct classification to 71.6% while the non-linear technique of Kohonen feature maps reached 73.7% correctness. Application of the multilayer perceptron even classified 79.8% of the gymnasts correctly. The combination of different predictive models for talent selection can avoid deselection of high-potential female gymnasts. The selection procedure based upon the different statistical analyses results in decrease of 33.3% of cost because the pool of selected athletes can be reduced to 92 instead of 138 gymnasts (as selected by the coaches). Reduction of the costs allows the limited resources to be fully invested in the high-potential athletes.     

Host society's dislike of the Islamic veil: The role of subtle prejudice, values, and religion

The wearing of the Islamic veil by Muslim women has become a source of tensions in Western European countries. In order to investigate majority members’ attitudes towards the veil, the present two studies (Ns = 166 and 147), carried out in Belgium, integrated three lines of research that have focused on (a) the role of subtle prejudice/racism on the host society's attitudes towards immigrants, (b) the role of values on acculturation, and (c) the role of religious attitudes on prejudice. Results revealed the effects of subtle prejudice/racism, values (self-enhancement values and security versus universalism), and religious attitudes (literal anti-religious thinking versus spirituality), in predicting greater levels of anti-veil attitudes beyond the effects of other related variables such as age and political conservatism. The studies also suggest the importance of including religious attitudes as part of the intergroup-relation factors that predict attitudes towards immigrants, at least with regard to specific components of intercultural relations.     

The role of engineering in fatigue reduction during human locomotion — a review

The purpose of this review is to discuss how an athlete’s fatigue can be limited by using recent innovations in sports engineering. The review focuses on human locomotion, i.e. mainly fatigue during endurance sports. First, through a general definition and illustrations of means of locomotion such as running, cycling, walking/hiking or speed skating, several aspects of fatigue reduction will be presented. With regards to the mechanical stress, it has been shown that (i) contrary to ‘invitro’ experiments and, in comparison with hard shoes, soft shoes do not appear to reduce impact forces during running and (ii) too much cushioning can have side effects in terms of energy cost and thus in terms of fatigue in running and mountain biking. On the contrary, the equipment weight-that also depends on the weight repartition may have dramatic effects in terms of fatigue. Any equipment allowing better mechanical efficiency (e.g. chainrings, klapskate) or work distribution (e.g. walking with poles) can potentially reduce an athlete’s fatigue under similar conditions without this equipment. However, among elite athletes, the use of technical innovation does not seem to affect fatigueper se but provides performance improvement with similar fatigue occurrence. It appears that fatigue-related improvements caused by technical innovations only occur among sportsmen exercising for leisure. In the second part of this review, recent textile innovations aimed at decreasing fatigue by the use of elastic compression stockings or at regulating temperature will be discussed. Finally, two methods designed to improve recovery after training or competition (elastic compression and electromyostimulation) will be discussed. Both these techniques are widely used by elite athletes despite relatively poor scientific evidence of their efficiency, with the exception of recovery after eccentric exercise.     

The measurement of competitive anxiety during balance beam performance in gymnasts

The purpose of the present study was to investigate competitive anxiety during balance beam performance in gymnasts. Competitive anxiety was assessed continuously by heart rate monitoring and by retrospective self-report of nervousness in eight female national level gymnasts during their balance beam routine during one competition and two training sessions. A significant negative correlation was found between the score of the retrospective self-report of nervousness and performance during the routine. There were no significant differences in performance score by the judges between the three test sessions. There were also no differences in the retrospective self-report of nervousness. However, heart rate was significantly higher during the competition session than during the training sessions. The potential value of the retrospective report of nervousness for the study of critical events during gymnastic performance is illustrated. The results are discussed in the light of catastrophe theory.     

Effects of contrasting colour patterns of the ball in the volleyball reception

The effects of three different colour patterns on the surface of volleyballs (versus that of a plain white ball) on the behaviour of a reception player were examined by presenting sidespin volleyball serves. Expert (n = 10) and novice (n = 10) volleyball players intercepted volleyballs projected straight at them or at an initial angle of 9.5 degrees outwards but eventually curving towards the players' original position. In the latter trajectories, players generally took one or more steps laterally before returning to the landing position of the ball. These excursion patterns were significantly more pronounced with the white balls than the coloured balls. Differences between balls of different colour combinations were also observed. The first finding supports the thesis that next to a prospective type of control, such as on-line maintenance of a certain spatiotemporal relationship between the player and the ball, properties of the ball itself allow prediction of the future path of the ball. Differences between types of colour patterns are explained within the framework of the between-colours wavelength contrasts of each type of ball.     

Functional impact of emotions on athletic performance: Comparing the IZOF model and the directional perception approach

A plausible explanation for the ancient long jump records from Greek antiquity is sought on the basis of pictorial and written sources, and corroborated with practical tests. Ancient sources report that athletes jumped more than 15?m with weights in their hands, which enabled them to jump further than without these weights. It is proposed that the ancient Greek long jump was a continuous succession of five standing broad jumps, in which the landing phase of one jump was also the countermovement for the next jump. Four trained athletes jumped further with (14.64?±?0.76?m, range 13.64?–?15.63?m) than without weights (13.88?±?0.70?m, range 12.60?–?14.75?m; P = 0.001). These results show that this technique is executable, fits with ancient written and pictorial sources, and allows trained modern athletes to jump distances well over 15?m. The extra distance jumped when using weights may be due to changes in the position of the jumper's centre of mass at take-off and at landing, and an increase in take-off velocity stemming from several biomechanical mechanisms.
