The key to success in elite athletes? Explicit and implicit motor learning in youth elite and non-elite soccer players

In sports, fast and accurate execution of movements is required. It has been shown that implicitly learned movements might be less vulnerable than explicitly learned movements to stressful and fast changing circumstances that exist at the elite sports level. The present study provides insight in explicit and implicit motor learning in youth soccer players with different expertise levels. Twenty-seven youth elite soccer players and 25 non-elite soccer players (aged 10–12) performed a serial reaction time task (SRTT). In the SRTT, one of the sequences must be learned explicitly, the other was implicitly learned. No main effect of group was found for implicit and explicit learning on mean reaction time (MRT) and accuracy. However, for MRT, an interaction was found between learning condition, learning phase and group. Analyses showed no group effects for the explicit learning condition, but youth elite soccer players showed better learning in the implicit learning condition. In particular, during implicit motor learning youth elite soccer showed faster MRTs in the early learning phase and earlier reached asymptote performance in terms of MRT. Present findings may be important for sports because children with superior implicit learning abilities in early learning phases may be able to learn more (durable) motor skills in a shorter time period as compared to other children.     

Multivariate analyses of individual variation in soccer skill as a tool for talent identification and development: utilising evolutionary theory in sports science

The development of a comprehensive protocol for quantifying soccer-specific skill could markedly improve both talent identification and development. Surprisingly, most protocols for talent identification in soccer still focus on the more generic athletic attributes of team sports, such as speed, strength, agility and endurance, rather than on a player’s technical skills. We used a multivariate methodology borrowed from evolutionary analyses of adaptation to develop our quantitative assessment of individual soccer-specific skill. We tested the performance of 40 individual academy-level players in eight different soccer-specific tasks across an age range of 13–18 years old. We first quantified the repeatability of each skill performance then explored the effects of age on soccer-specific skill, correlations between each of the pairs of skill tasks independent of age, and finally developed an individual metric of overall skill performance that could be easily used by coaches. All of our measured traits were highly repeatable when assessed over a short period and we found that an individual’s overall skill – as well as their performance in their best task – was strongly positively correlated with age. Most importantly, our study established a simple but comprehensive methodology for assessing skill performance in soccer players, thus allowing coaches to rapidly assess the relative abilities of their players, identify promising youths and work on eliminating skill deficits in players.     

济南市举办第十一届全运会经济及社会效应研究

本文在分析第十一届全运会对济南社会经济发展影响作用的基础上，着重对全运会经济及社会效应进行了理论探讨，认为全运会效应具有很强的正负影响效果。全运会正效应具体表现为经济效应、社会效应、环境效应；负效应表现为虹吸效应、低谷效应和风险效应。应充分利用全运会的正效应，规避负效应。进而提出：为实现全运会经济社会效应最大化，应调整政府在全运会承办中的职能，推行全运会市场化运作；并给出实施第十一届全运会市场化运作的具体建议措施。     

蔬菜栽培课程产学合作教育的实践与思考

选择具有日光温室、塑料大棚、中棚及露地等多种生产方式，蔬菜种类较多，面积较大，种植蔬菜历史较长，交通便利的村寨作为蔬菜栽培课程产学合作教育的基地。把学生分配到农户，每户3～4名学生为一组，与蔬菜生产实际紧密结合，让学生接受培养土的配制，种子处理与播种，苗床管理，定植，田间管理及嫁接育苗等环节的训练。结果表明：学生获得了两个层面的训练。在第一个层面上，学生熟练掌握了蔬菜栽培基本环节的技术要求和要领，动手能力得到明显提高，培养了学生的基本技能；在第二个层面上，学生掌握了蔬菜设施栽培、无公害生产综合配套等高层次技术，培养了学生综合技术应用能力。今后应特别注意学生和生产者(企业或农户)的双向参与，信息的双向传递，学校与生产者(或企业或农户)双赢，以及培养学生创新能力即第三个层面的训练。
