构建我国学校体育保险机制的研究

随着学校体育运动的蓬勃开展,在体育教学、训练和比赛中出现的运动伤害事故逐渐增多,由此引发的学生、家长与学校之间关于运动伤害事故纠纷的案件频频出现.加强对我国学校体育保险机制的研究与探讨,能够有效地迎合我国学校体育活动的开展.建立我国学校体育保险机制,对解决学生在运动过程中出现伤害事故后带来的诸多问题,消除学生在运动过程中的后顾之忧,具有重要的意义和作用.     

高等体育院校投掷专项本科生运动损伤的调查分析及其预防

1前言投掷项目包括推铅球、掷铁饼、掷标枪和掷链球。虽然各项目中的器械形状、重量以及技术形式各不相同,但合理的技术动作都遵循着共同的规律。按项群理论的划分,投掷运动属于体能主导类快速力量性项目。投掷运动中各项目的技术动作过程均是由握持器械、助跑、最后用力、缓冲     

我国排球运动员的损伤研究(综述)

排球运动是世界上流行的运动项目之一，排球运动员的损伤率估计在二到五人每一千训练比赛小时，主要的损伤部位是在肩、腰、膝、踝等部位，运动损伤方面的研究目前还不成体系，因为各研究的损伤标准不一。为了减少运动损伤的发生率，从内外两个方面综述运动损伤发生的原因及其预防措施。     

Between-limb differences in running technique induces asymmetric negative joint work during running

Negative work, which is mainly generated by eccentric muscle contraction, has an important influence on the associated muscle damage. Generally, mechanical parameters are determined for one side of a lower extremity on the assumption of negligible between-limb differences. However, between-limb differences in the negative work of lower extremity joints during running remain unclear. This study examines between-limb differences in negative work and associated mechanical parameters during the contact phase of running. Twenty-five young adult males voluntarily participated in this study. Each participant was asked to run on a straight runway at a speed of 3.0?m?s^?1. Negative work, amplitude, duration of negative power, moment, and angular velocity were computed for both sides of the lower extremities. Significant differences were found in negative work between limbs for the hip (18.9?±?11.7%), knee (13.6?±?10.4%), and ankle (11.8?±?8.5%) joints. For the hip joint, asymmetric negative work was attributable to the between-limb difference in the amplitude of negative power owing to a corresponding difference in the moment. The between-limb differences concerning the duration and amplitude of negative power could explain the asymmetric negative work in the knee joint. The asymmetric negative work of the ankle joint was attributable to the between-limb difference in the amplitude and duration of the negative power and the moment. These results indicate that asymmetric negative work was generated in each lower extremity joint; however, the major mechanical parameters corresponding to the negative work are not the same across the joints.     

精英运动员运动损伤的心理预防： 理论模型和研究展望

为有效预防竞技运动损伤,促进业界重视心理因素在预防损伤中的作用,对国外竞技运动损伤心理预防的概念模型和框架进行梳理,发现各类心理因素对发生运动损伤的影响路径被进一步整合和细化,不同水平层次的社会心理学因素开始受到重视,无论是特质理论还是应激—损伤理论、行动理论、状态理论,都强调了压力反应这一重要变量,全面、多方位考察风险文化和行为以及生物心理社会因素互动的理论视角是该主题未来的趋势。未来需要规范运动损伤的定义和测量方法,有必要开展运动员及其有关情况的针对性调查,还应该注重重复测量研究设计以及使用被忽视的结构方程模型检验变量的中介效应。     

我国校园足球可持续发展的若干问题研究

发展校园足球是推进我国校园体育活动的重要力量,亦是提升我国足球运动水平的必然选择。虽然在相关政策的支持下,我国校园足球发展迅速,但依然面临经费短缺、师资不足、发展不均衡、学训矛盾突出、体制机制不完善、社会认可度不高、医疗保障体系不健全等问题。指出,学校应密切联系俱乐部、企业,多渠道获取发展资源;从内部培养与外部引进两方面充实师资力量;坚持全面发展原则,妥善解决学训矛盾,提升学生综合素质;加强足球文化建设,营造良好氛围,提升足球参与者的荣誉感;强化校园足球风险防范意识,加强风险管理。旨在促进我国校园足球健康可持续发展。     

困境与出路：我国性侵运动员犯罪行为的刑事规制探究

近年来,性侵运动员的犯罪行为频发,成为国际社会聚焦的热点。以此审视我国运动员性法益的保护,虽有强奸罪、强制猥亵罪的刑事立法,却缺乏对该犯罪行为特殊性的深入思考,既不能在惩治犯罪人方面达到理想效果,亦不能在预防犯罪方面发挥良好功能。同时,司法中的“以纪代法”、针对性缺乏、未回应被害人需求等诸多问题,亦使该犯罪行为的刑事规制效果大打折扣。所以,在该犯罪立法上应有针对性采用附属刑法进行修正,完善犯罪的特别预防与一般预防制度;司法上,积极回应被害人的诉求,努力克服刑事规制过程中的各种困境,让运动员的性法益得到全面而充分的保护。     

Sex differences in elbow and wrist joint loading during the cartwheel and round off with different hand positions performed by young gymnasts

The aim of the study was to determine if sex differences exist in the key elbow and wrist joint injury risk factors during different cartwheel (CW) and round-off (RO) techniques performed by young male and female artistic gymnasts. Sixteen active young gymnasts (8 males and 8 females) performed 30 successful trials of CW and RO with three different hand positions (parallel (10), T-shape (10) and reverse (10)). Synchronised kinematic and kinetic data were collected for each trial. Two-way repeated measures ANOVA (3 × 2, technique × sex) and effect-sizes (ES) were used for statistical analysis. In conclusion, female gymnasts exhibited greater normalised peak vertical ground reaction forces (VGRF), elbow and wrist compression forces and elbow internal adduction moments during CW and RO skills compared with male gymnasts. In both sexes, the parallel and reverse techniques increased peak VGRF, elbow and wrist compression forces and the elbow internal adduction moment. Increased elbow flexion resulted in decreased peak VGRF, elbow compression forces and elbow internal adduction moment. Injury risk factors including elbow extension and internal adduction moment with axial compression force suggest that a CW and RO in reverse and parallel techniques can be hazardous especially for young female gymnasts.     

乒乓球运动员以预防损伤为主的功能训练

功能训练的理念来源于康复领域,现已逐步应用到运动训练中。由于乒乓球运动的项目特征,乒乓球运动员肩关节、腰椎关节、膝关节、踝关节、腕关节等部位容易出现运动损伤。通过对乒乓球运动员常出现的功能问题进行分析,寻找存在的常见问题,进而提出相应的功能训练建议。乒乓球运动员可根据情况,增加改善肩关节、胸椎关节、髋关节、踝关节的活动范围的训练,提高肩胛骨、核心和下肢稳定性的训练,以及改善肩袖、躯干肌力不平衡的训练,通过针对性的功能训练有效减少乒乓球运动员损伤的发生。     

竞技游泳运动员运动性伤病情况调查分析

采用问卷调查法对浙沪两省市194名游泳运动员进行运动性伤病调查,主要从运动性伤病的类型、部位、性质方面对比分析不同竞技水平游泳运动员的伤病表型特征。结果显示：优秀运动员运动性损伤较常见,多以慢性劳损为主,损伤部位依次为肩关节、腰背部和膝关节;一般运动员常发生急性损伤,损伤部位依次为膝关节、肩关节和腰背部。两组运动员鼻炎和中耳炎均常见。因此,依据运动性伤病的可能原因与机制,需要制定有针对性的预防措施,以减少运动性伤病的发生。
