The effect of smartphones and playing video games on decision-making in soccer players: A crossover and randomised study

ABSTRACT

The objective of this study was to analyse the effect of the use of social networks in smartphones or playing video games on the passing decision-making performance in professional soccer athletes. Participants were 25 male professional soccer athletes (mean ± SD: age 23.4 ± 2.8 years). The participants performed three randomised conditions divided into three groups: control (CON), smartphone (SMA), and video game (VID). Before and after each experimental condition, the Stroop Task assessed the level of induced mental fatigue. Then, the athletes performed a simulated soccer match. A CANON® camera recorded the matches for further analysis on passing decision-making performance. A group effect was identified (p < .01) with impairment on passing decision-making performance for the SMA (p = .01, ES = 0.5) and VID (p = .01, ES = 0.5) conditions. We concluded that the use of social networks on smartphones and/or playing video games right before official soccer matches might impair the passing decision-making performance in professional soccer athletes.

体育非物质文化遗产福建地术拳传承模式与传承路径探析

体育非物质文化遗产是我国传统体育文化的重要组成部分,对体育非物质文化遗产的保护和传承具有重要的意义。本文运用文献资料法、田野调查法对福建地术拳的传承发展的历史、现状及传承模式和传承路径进行梳理和归纳。研究发现福建地术拳并非单纯沿用传统的自然传承模式,而是在近一个世纪的传承过程中逐渐摸索出一条“以政宣武,以商养武,以武助商”的具有自我特色的传承模式和“六进”的传承路径。     

舞蹈艺术的意境创造——兼论中国书画与舞蹈的共通性

境界说是我国传统文艺美学的重要理论,主张艺术作品要创作出"象外之象""景外之景""韵外之致"和"味外之旨",以达到"言有尽而意无穷"艺术境界的审美要求,并认为只有创造出具有一定艺术境界的作品,才是具有高格的上品。本文以《扇舞丹青》这部作品为入径进行分析,探寻古典舞蹈与中国传统书画艺术相结合的艺术境界。

An Informetric Investigation into the Potential for Change in Belgian Art Education at the Beginning of the Twentieth Century

The beginning of the twentieth century was a period of pedagogical enthusiasm and renewal in the field of education. Based on a list of articles concerning art education published in Belgian periodicals between 1903 and 1923, the author undertakes an analysis of the title words in order to study how the subject was able to evolve. For this purpose, the pertinent title words are grouped into content categories. It can be seen that these content categories demonstrate specificity compared to other periods. The specificity of the subject at a given moment implies that the transformation of the subject consists of the emergence, the decline or the exchange of categories, which can also be demonstrated. The connections of these variations to historical facts are substantiated. It can therefore be stated that these variations represent the historical evolution of the subject. However, such emergence, decline and exchange of categories is only possible on condition that each category is able to vary independently of the others. This is shown by an autonomy index as well as by an 2‐test. Thus, art education did not drop from the sky as a ready‐to‐teach school subject. Art education is always what the people make of it, which makes reflection on what it could be or has to be so important at any given moment too.
