Dribbling speed in soccer is considered critical to the outcome of the game and can assist in the talent identification process. However, little is known about the biomechanics of this skill. By means of a motion capture system, we aimed to quantitatively investigate the determinants of effective dribbling skill in a group of 10 Under-13 sub-elite players, divided by the median-split technique according to their dribbling test time (faster and slower groups). Foot-ball contacts cadence, centre of mass (CoM), ranges of motion (RoM), velocity and acceleration, as well as stride length, cadence and variability were computed. Hip and knee joint RoMs were also considered. Faster players, as compared to slower players, showed a 30% higher foot-ball cadence (3.0 ± 0.1 vs. 2.3 ± 0.2 contacts · s^?1, P < 0.01); reduced CoM mediolateral (0.91 ± 0.05 vs. 1.14 ± 0.16 m, P < 0.05) and vertical (0.19 ± 0.01 vs. 0.25 ± 0.03 m, P < 0.05) RoMs; higher right stride cadence (+20%, P < 0.05) with lower variability (P < 0.05); reduced hip and knee flexion RoMs (P < 0.05). In conclusion, faster players are able to run with the ball through a shorter path in a more economical way. To effectively develop dribbling skill, coaches are encouraged to design specific practices where high stride frequency and narrow run trajectories are required.  相似文献

言语技能的掌握与外语基本能力的培养     

郝勇 《湖北广播电视大学学报》2006,23(1):51-53

掌握外语不仅要掌握关于外语的知识,重要是熟练运用外语的各种言语技能。外语的各种技能之间有着不同程度的依存关系,或相互影响,或相互补充,对一种技能的掌握有利于另一种技能的发展。从学习者的心理特点上看,掌握外语言语技能可以分为三个层级。提高外语教学质量的关键就在于如何有效地推动和加速三个掌握层级上的发展和变化,而加速三个掌握层级的发展变化的基本途径就是要培养学习者的基本外语能力。  相似文献

Key Concepts From Health Promotion Evaluations: What Psychology Needs to Know     

Shelly Russell-Mayhew 《International journal for the advancement of counseling》2006,28(2):167-182

Competing perspectives and debates about the meaning of health promotion and the best ways to evaluate the effectiveness of initiatives that focus on enhancing wellness pervade the literature. Given the emergence of health promotion, the impetus for outcomes-based practice in psychology, and the push for evidence-based care in the health system (Thorogood & Coombes, 2000), demonstrations of value and effectiveness are fundamental to the sustainability of mental health promotion activities. Psychology (and counseling as a sub-set field) needs to place itself as a profession vital to the sustainability of wellness initiatives. This paper proposes that psychologists’ awareness and understanding of six key concepts from health promotion evaluation are essential for advancing psychology as a profession and enhancing applied practice for wellness initiatives. The key concepts include: formative, process and outcome evaluations, the qualitative/quantitative debate, the ecological nature, the participatory approach, the focus on community and the underlying philosophies of empowerment and utilization. The use of key concepts from health promotion evaluation strategies support psychologists to a) deal with issues of major public health importance and b) collaborate with other disciplines for the benefit of the public (Sartorius, 1999). Finally, this paper makes recommendations to secure psychology’s place as a vital contributor to future research directions in health promotion, in part because of adherence to the scientist-practitioner model.Whilst Psychology is the generic term used here to represent the broad field, counseling as a sub-set in the discipline is particularly relevant for the ideas and issues discussed. Rather than adding the sub-set qualifier each time the broad field is referred to, the reader in this context is encouraged to hold this perspective of the place of counseling in regard to psychology as they work through the materials presented.  相似文献   

试论歌唱艺术的再创作

音乐是一门表演艺术。在音乐表演中将作曲家的创作称为第一次创作，而表演者的表演则称作再创作。对于声乐演唱而言，具有高超的演唱技巧与技术是进行再创作的重要前提。只有二者共同存在着完美融合，才会产生令人心动的音乐，两者缺一不可。  相似文献
