Physical Activities through Postcolonial Eyes: A Place of Epistemologic and Historiographical Experimentation

This contribution has a triple objective. The first is historical; it is to identify works, analysis, and perspectives covering the history of sport, which relate to the field of Postcolonial Studies developed elsewhere. By discussing anglophone and francophone works, we try to show the differentiated dynamics of research carried out in these two areas, while highlighting what each one owes to the other and vice versa. The second aim is analytical. We try to bring out the main themes of these works while proposing – from a postcolonial perspective – possible areas of research to pursue. Finally, the last objective is epistemologic. It discusses some problematic areas of interpretation around the role of physical activities in the process of colonization and decolonization.     

Survey Exploring Views of Scientists on Current Trends in Chemistry Education

A survey exploring the views of scientists, chemists and chemical engineers, on current trends in Chemistry Education was conducted in Greece. Their opinions were investigated using a questionnaire focusing on curricula (the content and process of chemistry teaching and learning), as well as on the respondents’ general educational beliefs and their underlying epistemological views. The aim of this work was to investigate the respondents’ opinions and, if possible, to identify the areas where convergence or even consensus occurred. The results showed that some of the items on the research questionnaire produced a high degree of agreement with the respondents’ views, while a few others were exactly the opposite. These items are considered to be representative of more widespread views. In order to explore the diverging opinions, the items on the research questionnaire that showed great variance were analyzed to determine, whether or not there were significant inter-item correlations among subgroups of participants with different demographic characteristics. Postgraduate studies, professional occupation, age/experience, and career within or outside the wide educational sector were among the main factors that significantly influenced the research results. The study did not reveal any single belief framework underlying the opinions of the respondents. Nevertheless, three specific approach frameworks—ACADEMIC, CONSTRUCTIVIST and SCIENTIFIC REALISM—were analyzed to determine which had the highest degree of agreement. It was found that the SCIENTIFIC REALISM framework and the curriculum emphasis characteristic of the context-based CTSE (Chemistry, Technology, Society and Environment) prevailed, as they produced a significantly higher mean score. The ACADEMIC framework followed with a moderate mean score and the CONSTRUCTIVIST framework had a lower mean score.     

Contagious Media Effects: How Media Use and Exposure to Game-Framed News Influence Media Trust

The purpose of this study is to investigate the extent to which trust in media is affected by personal media use and the framing of politics as a strategic game. The study is based on a four-wave panel survey matched with media content data, which allows us to investigate not only correlations but also individual-level effects on media trust. In accordance with previous research, our analyses show that the use of specific media types leads to more trust in those specific media. The results also show that media framing of politics as a strategic game has a negative effect on trust in the media. The more citizens are exposed to game-framed news, the less they tend to trust the media, with the exception of tabloid newspapers. Overall, these results lend support to the assumption of contagious effects of game-framed news. In a concluding section, we sum up our results and discuss the implications of our findings.     

Effects of Training on the Estimation of Muscular Moment in Submaximal Exercise

Abstract

The purpose of this study was to observe the effects of a submaximal isometric training program on estimation capacity at 25, 50, and 75% of maximal contraction in isometric action and at two angular velocities. The second purpose was to study the variability of isometric action. To achieve these purposes, participants carried out an isokinetic extension movement of the dominant lower limb during six test sessions and nine training sessions. Following the training program, estimation capacity in the different actions did not improve. However, an improvement in performance was observed with a reduction in the variability of submaximal isometric actions. The proprioceptors activated in isometric action seemed to adapt to the training program itself, which would promote better adaptation by a greater solicitation of internal feedback.     

The Relative Age Effect in Elite Sport

The relative age effect (RAE) is considered a common phenomenon in elite sport. However, it has not been examined systematically in previous research, and the mechanisms likely to generate or to limit such an effect are little understood. This paper investigates the prevalence of the RAE in French professional championship-level players, taking into account the potential influence of gender. Among all investigated sports, no statistically significant RAE was found, except for male ice hockey. For male handball and rugby union a trend was detected, but the RAE did not appear statistically significant. In line with previous studies, no significant RAEs were found in female elite sports. The results are discussed with regard to the potential mechanisms underlying RAE.     

Interdisciplinary Research: A Promising Approach to Investigate Elite Performance in Sports

While the call for interdisciplinary studies has been loud and clear over the last decade or so, the number of interdisciplinary publications in sport sciences is rather limited. One of the reasons for this scarcity is the complexity of the research process itself. Still, the combination and integration of information from different scientific disciplines seems to be important to better explain how elite performance comes about. In this article, we focus on this issue and discuss the advantages of interdisciplinary research for understanding how elite athletes are able to achieve such high-proficiency levels. The first section provides an overview of the studies that investigated elite performance in sports. In the second section, we focus on the issue of interdisciplinarity and illustrate how the ecological–dynamical approach and the concept of dimensional reduction can be used to explain how elite performers cope with the complex nature of sport skills. In the last section, we present a research outline and some practical considerations that can be helpful for researchers who aim to study sport skills from an interdisciplinary perspective.
