广东省第三届高校体育教育专业学生基本功大赛田径专项成绩分析

本文对广东省第三届高校体育教育专业大学生基本功大赛田径专项的竞赛成绩进行分析。研究得出:(1)专项技能方面,师范类院校和体育院校的专项技能展示比综合性院校较好;大部分院校男生的专项技能展示比女生的成绩突出;(2)教学技能方面,各个学校之间存在较大差异,综合性大学也有优异的表现。因此,对于体育教育田径专项人才培养方面,既要有理论的基础学习,又要发展学生的运动技能。

Challenges to Brand Australia: international students and the problem with speaking

Although communication skills in English are important for both their career prospects and the success of their overall study experience, many international students find their spoken English a barrier to employment after graduation. In this paper, we draw on longitudinal interview data from international postgraduates to investigate the individual and social factors that impacted on the development of their speaking skills as they studied in Australia. Our findings suggest that, despite high levels of motivation to improve, they received little instruction in such skills on their English for Academic Purposes programs and had little access to them in the community. We argue that for compelling moral as well as economic reasons universities urgently need to address these issues through both instruction and social integration initiatives if they are to safeguard their lucrative but vulnerable overseas markets.     

Examining the influence of grip type on wrist and club head kinematics during the golf swing: Benefits of a local co-ordinate system

Wrist movements have been identified as an important factor in producing a successful golf swing, with their complex motion influencing both club head velocity and orientation. However, a detailed analysis of wrist angles is lacking in the literature. The purpose of this study was to determine kinematics across wrists and club head characteristics during the golf swing under weak, neutral and strong grip conditions. Twelve professional male golfers executed 24 shots using a driver under three grip conditions. A six degrees of freedom analysis of the hand with respect to the distal forearm was performed using a 10-camera three-dimensional motion capture system. Differences in joint angles were explored using repeated measures ANOVAs at key swing events (onset, top of backswing and impact), in addition club head velocity and clubface angle at impact were also explored. Main findings revealed significant differences in flexion/extension and internal/external rotation for both wrists at all swing events, whereas fewer significant interactions were found in ulnar/radial deviation across grips for both wrists at all events. Clubface angle only differed significantly between the weak and the strong and neural grips, presenting a more ‘open’ clubface to the intended hitting direction. This study is the first to explore tri-planar wrist movement and the effect of different grips, such analysis has implications for coaching knowledge and practice and should inform future research into different aspects of skill, technique analysis and may inform injury mechanisms/prevention.     

基于HHD测试的男子羽毛球运动员肩关节旋转特征分析

目的:通过观察男子羽毛球运动员肩关节旋转活动度及肌力的特征,为羽毛球运动员肩关节损伤的预防和康复提供参考。方法:以16名专业羽毛球男子运动员为受试对象,同时以9名普通男子为对照,使用手持式测力计(HHD)测定优势侧及非优势侧肩关节的旋内、旋外肌力;同时,测量其旋转被动活动度。结果:(1)男子羽毛球运动员肩关节旋外被动活动度大于旋内被动活动度。(2)男子羽毛球运动员肩关节优势侧旋内、旋外肌力均大于非优势侧,但旋外/旋内比例不存在双侧差异。结论:(1)男子羽毛球运动员肩关节旋转活动度存在双侧差异。(2)男子羽毛球运动员优势侧肩关节旋内、旋外肌力均大于非优势侧。     

Effectiveness of physical education to promote motor competence in primary school children

Background: Motor skill (MS) competence is an important contributing factor for healthy development.

Purpose: The goal was to test the effectiveness of primary school physical education (PE) on MS and physical fitness (PF) development.

Methods: Three classes (n?=?60, aged 9.0?±?0.9) were randomly assigned to three diverse conditions during a school year: two PE lessons/week (PE-2), three PE lessons/week (PE-3), and no PE lessons control group (CG). BMI, skinfolds, PF (9-min run/walk, sit-up, modified pull-ups), gymnastics, soccer, handball, basketball and track-and-field skills were evaluated. Effect sizes (d) were reported as magnitude of change.

Results: Skinfolds significantly increased only in CG (d?=?1.21). PF composite z-scores improved in PE-3 (d?=?0.61), but decreased in PE-2 (d?=?0.57), and had no changes in CG. Statistically significant improvement was verified in gymnastics and handball skills in both experimental groups (gymnastic: d?=?2.95 and d?=?2.61 for PE-3 and PE-2, respectively; handball: d?=?1.87 and d?=?0.57 for PE-3 and PE-2, respectively), and no changes were seen in CG. In soccer, there were improvements only in the PE-3 (d?=?0.55), and in basketball only in PE-2 (d?=?0.46). There were no changes in any group for track-and-field skills.

Conclusions: PE programs can effectively promote PF and MS development.
