In basketball, the defender’s reaction to a pass is slower and more error prone if the attacking player gazes into the opposite direction. This so-called head-fake effect might be modulated by context information, that is, the frequency and the sequence of head fakes occurring. Accordingly, the present study investigates the head-fake effect for different frequency proportions (20% vs. 50% vs. 80%). The results show that the head-fake effect decreases when the head fake occurs more often. Furthermore, a potential influence of previous fake experience (i.e., congruency-sequence effect) on the size of the head-fake effect was investigated. Importantly, previous fake experience did not cause the frequency-based modulation of the general size of the head-fake effect. These findings bare important implications for sports practice, especially when it comes to instructing players about the tactical use of deceptive actions.  相似文献

Abstract

Germany is both the country of origin of Protestantism and of Turnerism, which has led to a specific concept of national gymnastics. In 2017, the 500th anniversary of Martin Luther´s act of nailing his theses to the door of the Church of Wittenberg (on 31 October 1517) was celebrated. About 300 hundred years later, Ludwig Jahn, son of a Protestant minister, started to run a gymnastics ground at a park in Berlin, where young boys and students were educated in ‘body and mind’ according to Jahn’s slogan (which later became the brand of the German Turner movement) frisch, fromm, fröhlich, frei (‘fresh, pious, cheerful, free’). The notion of piety has been widely discussed by contemporary gymnasts, because even then, some regarded piety as old-fashioned and in fact incompatible with a free and enlightened world. The purpose of this paper is to consider the Christian impact on German gymnastics and sport since the beginning of a civil movement of body culture in clubs and societies in the nineteenth century. The paper is based on a wide range of academic research and other selected sources.  相似文献

The Central Institute for Higher Education of Berlin is introduced and a short history of the institution is given. Founded in 1982, it is an example of a centralized national centre for research on higher education, having had responsibility for higher education research in the whole of the former German Democratic Republic. In order for the Institute to survive in the new, reunited Germany, it has had to change its strategies and the scope of its investigations which will now be arranged around four major fields of investigation. Having acquired great expertise in the study of higher education in the former German Democratic Republic and also having done work on the higher education systems of the other European socialist countries, the Institute is currently well suited to continue its specialization in eastern European higher education affairs and to make very positive contributions in the future.  相似文献

Knee joint forces during downhill walking with hiking poles   总被引:1,自引:0,他引:1  
The aim of this study was to determine external and internal loads on the knee joint during downhill walking with and without hiking poles. Kinematic, kinetic and electromyographic data were collected from eight males during downhill walking on a ramp declined at 25 degrees. Planar knee joint moments and forces were calculated using a quasi-static knee model. The results were analysed for an entire pole-cycle as well as differentiated between single and double support phases and between each step of a pole-cycle. Significant differences between downhill walking with and without hiking poles were observed for peak and average magnitudes of ground reaction force, knee joint moment, and tibiofemoral compressive and shear forces (12-25%). Similar reductions were found in patellofemoral compressive force, the quadriceps tendon force and the activity of the vastus lateralis; however, because of a high variability, these differences were not significant. The reductions seen during downhill walking with hiking poles compared with unsupported downhill walking were caused primarily by the forces applied to the hiking poles and by a change in posture to a more forward leaning position of the upper body, with the effect of reducing the knee moment arm.  相似文献
