A scale-based approach to interdisciplinary research and expertise in sports

After more than 20 years since the introduction of ecological and dynamical approaches in sports research, their promising opportunity for interdisciplinary research has not been fulfilled yet. The complexity of the research process and the theoretical and empirical difficulties associated with an integrated ecological-dynamical approach have been the major factors hindering the generalisation of interdisciplinary projects in sports sciences. To facilitate this generalisation, we integrate the major concepts from the ecological and dynamical approaches to study behaviour as a multi-scale process. Our integration gravitates around the distinction between functional (ecological) and execution (organic) scales, and their reciprocal intra- and inter-scale constraints. We propose an (epistemological) scale-based definition of constraints that accounts for the concept of synergies as emergent coordinative structures. To illustrate how we can operationalise the notion of multi-scale synergies we use an interdisciplinary model of locomotor pointing. To conclude, we show the value of this approach for interdisciplinary research in sport sciences, as we discuss two examples of task-specific dimensionality reduction techniques in the context of an ongoing project that aims to unveil the determinants of expertise in basketball free throw shooting. These techniques provide relevant empirical evidence to help bootstrap the challenging modelling efforts required in sport sciences.     

Age and sex influences on running mechanics and coordination variability

The purpose of this study was to examine the impact of age on running mechanics separately for male and female runners and to quantify sex differences in running mechanics and coordination variability for older runners. Kinematics and kinetics were captured for 20 younger (10 male) and 20 older (10 male) adults running overground at 3.5 m · s^?1. A modified vector coding technique was used to calculate segment coordination variability. Lower extremity joint angles, moments and segment coordination variability were compared between age and sex groups. Significant sex–age interaction effects were found for heel-strike hip flexion and ankle in/eversion angles and peak ankle dorsiflexion angle. In older adults, mid-stance knee flexion angle, ankle inversion and abduction moments and hip abduction and external rotation moments differed by sex. Older compared with younger females had reduced coordination variability in the thigh–shank transverse plane couple but greater coordination variability for the shank rotation–foot eversion couple in early stance. These results suggest there may be a non-equivalent aging process in the movement mechanics for males and females. The age and sex differences in running mechanics and coordination variability highlight the need for sex-based analyses for future studies examining injury risk with age.

教育观念与英语交际能力的培养——以非英语专业博士研究生为例

传统的教育观念、语法翻译教学法和汉语教学模式对英语交际能力发展存在消极影响.交际法教学比语法翻译法更有利于英语交际能力的发展,本文以非英语专业博士研究生为研究对象,通过革新教学理念、课程体系、学习策略和教学手段等,对博士研究生英语教学进行改革,可以有效地提高博士研究生的英语交际能力.     

Engaging mothers with substance use issues and their children in early intervention: Understanding use of service and outcomes

Mothers who use substances need integrated, multi-sectoral intervention services to support substance use discontinuation. We explored mothers’ service use at Breaking the Cycle, an early intervention and prevention program for pregnant and parenting women and their young children in Toronto, Canada. We conducted retrospective analyses of families’ service records and client charts (N = 160). Aims were to 1) describe women’s use of service, 2) examine how early engagement of pregnant women related to postnatal service use, and 3) examine the circumstances in which women ended their service relationship with Breaking the Cycle. Specifically, we examined circumstances at service ending relating to women’s service goals; custody status with children; and global substance-use, parent-child relationship, and child development outcomes. We found that these vulnerable women were actively engaged in many services and for a long duration, early engagement was associated with greater service use, and greater service use was associated with more positive circumstances upon ending service. Results provide support for a relational approach to service that promotes not only the relationship between mother and child, and mother and service provider, but also highlights relationships among staff, between staff and management, and between community partners as integral to effective service delivery. Integrating positive relationships at all levels is critical to support vulnerable families with complex needs.     

中外男子撑竿跳高优秀运动员最后两步助跑至起跳技术相关运动学参数的比较研究

最后2步助跑至起跳技术是撑竿跳高中的关键技术环节。本文采用文献资料法、比较研究法,数理统计等方法对中外优秀男子撑竿跳高运动员最后2步助跑至起跳技术相关运动学参数进行对照。结果表明,我国优秀男子撑竿跳高运动员在身体重心运动轨迹变化、摆动膝角等多项指标中与世界优秀选手均存在一定差距,揭示我国优秀男子撑竿跳高运动员最后两步助跑至起跳技术的一般性规律与特征。为我国优秀男子撑竿跳高运动员的科学训练提供定量化参考依据。     

国内外优秀男子跳远运动员部分技术指标差异性分析

对国内外优秀跳远运动员和世界顶级跳远运动员的助跑速度利用率、短程和全程助跑跳远成绩差、K值三项指标进行对比分析,发现我国优秀男子跳远运动员助跑速度利用率明显高于世界顶级选手,但技术评定等级低于世界顶级选手,主要原因是起跳环节存在差距。不同运动员最佳的助跑速度利用率存在差别,高助跑速度利用率需要有与之相对应的起跳能力和跑跳结合能力。     

体育术科高考乒乓球专项考试方法与标准的探讨

本文通过对１９９７年浙江省体育术科高考宁波师院考点各项成绩的对比分析和乒乓球专项考试原始成绩的统计分析，认为乒乓球专项成绩远远优于其它项目，主要原因是其考试方法不够科学，评分标准明显偏低所致。因此，重新审定乒乓球考试方法和标准是深化我省体育术科高考改革中急待解决的重要课题之一。
