对高水平竞技体育训练的适应机制及其主要观点的思考 总被引:4,自引:0,他引:4

本文作者认为中国体能类项目落后的主要原因不在于“遗传、训练条件和训练的具体手段”等问题,而是缺乏科学训练的理念,在训练方向和指导思想方面没有跟上世界的发展。本文着重阐述了运动训练的生化基础,强调了训练必须遵循生物适应的原则,提出“最大的训练负荷并不能获得最佳的适应,适应的‘最佳’区域肯定位于运动员可承受负荷之下” 相似文献

Zusammenfassung. Industrielle Konfigurationsprozesse sind, bedingt durch die vorherrschende Variantenvielfalt, sehr komplex. Aufgrund der
inh?renten Potentiale ist die Realisierung von effizienten, flexiblen Konfigurationsprozessen ein zentrales Ziel vieler Unternehmen.
Wir haben einen Ansatz für die Konfiguration und Rekonfiguration von Produkten entwickelt, der auf Constraint-basierter Modellierung
über endlichen Dom?nen basiert. Das auf diesem Ansatz beruhende System ConBaCon deckt eine breite Palette von Konfigurationsproblemen
ab und erm?glicht eine effiziente L?sung, die sowohl automatisch als auch gesteuert durch hoch flexible Nutzerinteraktion
erfolgen kann. Wendet man das System jedoch auf gro?e Konfigurationsprozesse an, so treten Performanzprobleme auf. Als zwei
wesentliche Modellerweiterungen, die diesem Mangel entgegenwirken, stellen wir in dieser Arbeit einerseits eine Modell-Clusterung
und andererseits die Behandlung gro?er Netze arithmetischer Constraints vor.

Higher education research isclosely linked to the debates on highereducation policy and practice. It provides theinformation basis for decisions about thefuture of higher education. As the themes of the public debate on problems and reform needs in higher education change quickly, higher education research has to anticipate future problems andthemes of debates in order to develop conceptsand to generate knowledge well in advance.Future-conscious higher education researchmight aim to identify likely future changes inthematic areas which are already in thelimelight of public attention, as trends in theareas of expansion of higher education,diversification of structures of the highereducation system, system steering andinstitutional management as well asinternationalisation and globalisation suggest.Moreover, future-conscious higher educationresearch should try to identify thematic areasnot frequently discussed at present but likelyto be major issues in the future. For example,professionalisation of higher education interms of the emergence and expansion of newadministrative and service professions inhigher education institutions might havefar-reaching implications in the future and isworth to be paid attention by higher educationresearchers. 相似文献

Bicycle riding is a functional motor skill that increases physical activity opportunities, social interaction, and independence. However, bicycle riding is difficult for youth with autism spectrum disorder (ASD) to learn. This study examined the effectiveness of home-support consultation (HSC) on increasing the maintenance of independent bicycle riding following initial skill acquisition. Fifty-one youth with a confirmed ASD diagnosis learned to ride a two-wheeled bicycle during a training camp. Twenty-nine riders enrolled in a HSC intervention to promote distributed practice of the learned skill. The control cohort (N = 22) was exempt from the HSC intervention. One year following initial skill acquisition, 62.07% of the HSC cohort compared to 36.36% of the control cohort still reportedly displayed the skill. Within the HSC cohort, riders who reported at least 8 weeks of practice following acquisition on average maintained the skill. Implications of home consultation are discussed. 相似文献

In this article, a new research model for the study of pedagogical content knowledge (PCK) is presented which aims to improve teacher education. This model called “educational reconstruction for teacher education” (ERTE) represents the framework for an integrative approach to the study of science teachers’ topic specific PCK, which is a largely unexplored field. By integrating the PCK concept, originating in the American Curriculum tradition, into the German (Fach)didaktik tradition, this model adds a new perspective to (Fach)didaktik. This paper, therefore, also aims to clarify the PCK concept and its relation to Fachdidaktik. 相似文献

In the context of gross anatomy education, novel augmented reality (AR) systems have the potential to serve as complementary pedagogical tools and facilitate interactive, student-centered learning. However, there is a lack of AR systems that enable multiple students to engage in collaborative, team-based learning environments. This article presents the results of a pilot study in which first-year medical students (n = 16) had the opportunity to work with such a collaborative AR system during a full-day gross anatomy seminar. Student performance in an anatomy knowledge test, conducted after an extensive group learning session, increased significantly compared to a pre-test in both the experimental group working with the collaborative AR system (P < 0.01) and in the control group working with traditional anatomy atlases and three-dimensional (3D) models (P < 0.01). However, no significant differences were found between the test results of both groups. While the experienced mental effort during the collaborative learning session was considered rather high (5.13 ± 2.45 on a seven-point Likert scale), both qualitative and quantitative feedback during a survey as well as the results of a System Usability Scale (SUS) questionnaire (80.00 ± 13.90) outlined the potential of the collaborative AR system for increasing students' 3D understanding of topographic anatomy and its advantages over comparable AR systems for single-user experiences. Overall, these outcomes show that collaborative AR systems such as the one evaluated within this work stimulate interactive, student-centered learning in teams and have the potential to become an integral part of a modern, multi-modal anatomy curriculum. 相似文献
