False-performance feedback does not affect punching forces and pacing of elite boxers

Prior research indicates that providing participants with positive augmented feedback tends to enhance motor learning and performance, whereas the opposite occurs with negative feedback. However, the majority of studies were conducted with untrained participants performing unfamiliar motor tasks and so it remains unclear if elite athletes completing familiar tasks respond in a similar fashion. Thus, this study investigated the effects of three different versions of false-performance feedback on punching force (N), pacing (force over time) and ratings of perceived exertion (RPE) in 15 elite amateur male boxers. Athletes completed a simulated boxing bout consisting of three rounds with 84 maximal effort punches delivered to a punching integrator on four separate days. Day one was a familiarisation session in which no feedback was provided. In the following three days athletes randomly received false-positive, false-negative and false-neutral feedback on their punching performance between each round. No statistical or meaningful differences were observed in punching forces, pacing or RPE between conditions (P > 0.05; ≤ 2%). These null results could stem from the elite status of the athletes involved, the focus on performance rather than learning, or they may indicate that false feedback has a less potent effect on performance than previously thought.  相似文献   

从“暴力美学”视域审视武术散打运动     

连美雪  马剑 《中华武术(研究)》2020,(1):124-125,83

从“暴力美学”视角对武术散打进行审视与分析,在社会的现代化发展中,武术徒手格斗形式运动项目中的散打与暴力美学的结合表达了当前社会人们对格斗竞技类项目的态度与观点。散打运动中体现着暴力美学,外在展现的暴力动作实际上是内心世界的写照,同时也是观众内心情感的寄托宣泄。如今的社会,散打运动的独特魅力吸引着更多的人来认识它,攻防技击的本质是散打运动发展的基石,也是对它的准确定位。  相似文献   

The ‘aggressive style’: genesis of an ambiguous resource for Swiss hockey and football players     

Orlan Moret  Alan Traclet  Alain Clémence 《Sport in Society》2019,22(3):399-415

In this study, we investigated what drives players to endorse an aggressive style in Swiss ice hockey and football. We selected a sample of 16 players on the basis of their penalty statistics. We used semi-directed retrospective interviews to collect players’; biographic narratives. The results show a socialization process into an aggressive style, supported by the dominant gender and socialization norms of the sport, which is under the influence of the structure of the sports organization. However, there are large differences between players, with only some of them adopting an aggressive style. Although many studies have underlined the influence of moral disengagement, the present results suggest that time also matters and that the diversity of career paths may explain the diversity in attitudes. Socialization differences in the sports field, bodily capital, a career path marked by thwarted reputation are the key factors that drive players to adopt an aggressive style.  相似文献   

身体关怀:徐英超体质教育思想的形成动因、内在逻辑与当代启示     

邵天逸  李启迪 《沈阳体育学院学报》2020,(3):23-28

徐英超是"体质教育思想"的首创者,这一思想在我国学校体育发展史中具有重要的地位。运用文献资料法、逻辑分析法,通过不同的视角深度剖析徐英超体质教育思想,旨在呈现徐英超体质教育思想的形成动因与内在逻辑,并挖掘体质教育思想对当前学校体育的启示。研究认为徐英超体质教育思想的成因在于反思体育的概念,内在逻辑包含3个方面:体育教学的视点应从技术传习回归身体教育,实证调研是揭示与掌握体质变化规律的关键,良好的心态与生活方式是促进体质健康的外部保障。徐英超体质教育思想的当代启示:正视增强体质与技术教学之关系;参考体测结果调整体育教学方向;建构面向生活的体育健康教育观。  相似文献

现藏于南京博物院的一批无款写真头像《明人十二像册》,是中国写实画的一座高峰。对于这个像册的绘画风格,现当代学者多半都偏向认为是受到西方绘画的影响。但经与西方圣像画比较研究,像册仍属于中国本土的绘画传统,受到了宋代山水画和花鸟画高度写真精神的影响。  相似文献   

When teachers learn how to provide classroom structure in an autonomy-supportive way: Benefits to teachers and their students     

《Teaching and Teacher Education》2020

In two experimentally-based and longitudinally-designed studies, secondary-level PE teachers were randomly assigned to participate or not in a new intervention to help them learn all of the following: support autonomy, provide structure, and provide structure in an autonomy-supportive way. In Study 1, teachers who participated in the intervention showed longitudinal gains in all five hypothesized teacher benefits (e.g., teaching efficacy, job satisfaction). In Study 2, students of teachers who participated in the intervention showed longitudinal gains in all four hypothesized student benefits (e.g., classroom engagement, skill development). Overall, teachers and students benefited after teachers provided structure in an autonomy-supportive way.  相似文献   

军事技术学:跨学科学的一个典型案例     

晏湘涛  匡兴华 《科学学研究》2005,23(Z1):49-54

一方面由于现代科学技术综合化的发展趋势,另一方面由于战场体系对抗和武器装备体系的发展,军事技术的综合化、体系化发展已经成为大势所趋,并且发展成为军事技术学。军事技术学学科体系可以分解成基础研究-应用研究-发展研究的过程模型,也可以分解为共性基础技术-应用技术的层次模型,并且在不同的军事技术学体系中有不同的带头学科。从初级概括、系统普遍化和综合的理解三个层面上来看,军事技术学具有跨学科学的本质特征。因此,军事技术学是跨学科学的一个典型案例。认识到这一点,对军事技术学与跨学科学研究都有重要的意义。  相似文献

Coping styles in youth exposed to maltreatment: Longitudinal patterns reported by youth in foster care     

《Child abuse & neglect》2017

Coping styles in youth living in foster care with a history of maltreatment were examined to determine the nature and stability of self-reported coping behavior over time. Participants included 542 (time 1), 377 (time 2), and 299 (time 3) youth ages 8–22 years (M = 13.28 years, SD = 3.04). Using the Behavioral Inventory of Strategic Control, a dimensional, continuous measure of coping, across four possible coping styles endorsed in reference to specific potentially stressful situations, the results indicated that direct action coping was the most frequently endorsed or preferred style for more than 50% of the sample at each time point. A number of youth endorsed using more than one coping style, indicating some flexibility in the approach to coping when problems occur. Although most youth endorsed a preferred style, coping style endorsed did vary somewhat over time. The coping style endorsed also varied depending on the type of problem referenced, but no statistically significant differences were noted across situations, including social, academic, general, and foster-specific situations. Effects for age were also examined and the results indicated no significant differences across the age range for type of coping most commonly endorsed. The present study is the first large-scale, longitudinal assessment of coping styles in youth in foster care and the results suggest that coping is not a simple, categorical-only construct and the implications for the endorsement of the direct approach for youth in foster care along with the other findings are discussed.  相似文献
