晋陕蒙边界地区武术文化发展及成因          下载免费PDF全文

郭维维 《河北体育学院学报》2017,31(3):90-96

运用文献资料法和逻辑分析法,对晋陕蒙边界地区武术文化发展及成因进行研究.指出,该地区地处特殊的文化地理位置,形成了明显有别于农耕与游牧的半农半牧社会文化生态体系.伴随着两种文明的不断碰撞与交融,武术这一身体文化也在该地形成了独特的文化形态,并对摔跤、射箭和武术文化进行具体分析.对成因的探究显示,黄河是凝聚农耕思想的武术身体文化在晋陕蒙边界地区传播发展的根基与命脉,长期的民族冲突为武术技击的传承与发展提供了动力,移民则是武术文化在该地区传播的载体.  相似文献

明清捶丸运动的兴衰及其对当代高尔夫运动启示     

殷怀刚    陈〓刚  韩〓冬 《广州体育学院学报》2017,37(1):69-72

捶丸运动素有“中国式高尔夫”之称,其兴衰与变迁蕴含着复杂的社会成因,从中探求有益启示,为当代高尔夫发展提供借鉴.采用文献资料等方法,对明清时期捶丸运动的兴盛与衰落脉络进行梳理,探究明清捶丸运动流变的深层原因与当代启示.结论如下:清代统治阶级的娱乐导向是捶丸运动走向衰落的主要原因,该时期民族文化的融合与渗透、社会习俗与社会风气的变迁是其重要原因;当前高尔夫发展背离了正常的发展轨道,其生存与发展的社会环境面临着诸多困难;历史的经验给予我们启示,社会基础和社会需求是高尔夫球发展不可忽视的重要条件,而政府的导向作用对高尔夫的发展起到至关重要的作用.  相似文献   

In-house consultation to support professionals’ responses to child abuse and neglect: Determinants of professionals’ use and the association with guideline adherence     

《Child abuse & neglect》2017

This study examined the presence and strengths of determinants associated with consultation of an in-house expert on child abuse and neglect (CAN) by preventive child health care professionals who suspect CAN. This study also assessed the relationship between in-house CAN expert consultation and professionals’ performance of six recommended activities described in a national guideline on preventing CAN for preventive child health care professionals. A total of 154 professionals met the study’s inclusion criteria. They filled in a questionnaire that measured in-house consultation practices and twelve determinants associated with the professional, the in-house expert, and the organizational context. Bivariate and multivariate regression analyses were performed. Almost half of the participants (46.8%) reported to consult the in-house expert in (almost) all of their suspected CAN cases. Professionals who reported better recollection of consulting the in-house expert (i.e. not forgetting to consult the expert) (p = .001), who were more familiar with consultation (p = .002), who had more positive attitudes and beliefs about consultation (p = .011) and who reported being more susceptible to the behavior (p = .001) and expectations/opinions (p = .025) of colleagues regarding in-house expert consultation were more likely to consult the in-house expert. Furthermore, in-house expert consultation was positively associated with two of six key guideline activities: consulting the regional child protection service and monitoring whether support was provided to families. The implications of these results for improving professionals’ responses to CAN are discussed.  相似文献   

Nrf2在有氧运动训练中对小鼠骨骼肌抗氧化能力的作用     

何诗依  张缨 《北京体育大学学报》2017,40(12):50-54

摘要：目的：Nrf2是机体氧化还原平衡的主要调节因子，本研究试图探讨Nrf2在有氧运动训练中对小鼠骨骼肌抗氧化能力的作用。方法：8周龄野生C57BL/6J小鼠和Nrf2敲除小鼠40只，雌雄各半。进一步各为安静组和运动组，每组10只，共4组：分别为野生安静组（WC），野生运动组（WE），敲除安静组（KC）和敲除运动组（KE）。运动组进行4周运动强度为70%VO2max跑速的跑台运动，每周运动6 d，每天运动1 h。运动组最后一次运动后休息48 h脱颈处死，取小鼠后腿骨骼肌。RT-PCR测量Nrf2及Nrf2介导的抗氧化基因mRNA表达量；Western blot法测定骨骼肌Nrf2及抗氧化蛋白含量； GSH试剂盒测量GSH/GSSG比值。结果：1）在安静情况下，KC组和WC组相比，骨骼肌中GSR、NQO1、GCLc、GPX、HO-1和SOD2这6个抗氧化蛋白表达以及GSH/GSSG值没有显著性改变。 2）4周有氧运动训练之后，Nrf2敲除运动组的大部分抗氧化蛋白（CAT, NQO1-1, GCLc, HO-1 and SOD2）和GSH/GSSG值都要显著低于野生运动组。结论：4周70%VO2max强度的有氧运动训练，增加了成年Nrf2敲除和野生鼠骨骼肌抗氧化蛋白表达量和GSH/GSSG比值的差异，而在无训练安静情况下在两种鼠中这些指标的差异不大。说明Nrf2对有氧运动训练中骨骼肌的抗氧化反应起着非常重要的作用。  相似文献   

Biomechanics of judo backward breakfall for different throwing techniques in novice judokas     

Sentaro Koshida  Takanori Ishii  Tadamitsu Matsuda  Toshihiko Hashimoto 《European Journal of Sport Science》2017,17(4):417-424

It is generally accepted that proper learning of the breakfall technique during early judo training is essential for attenuating the risk of judo-related head injury. Therefore, it is critical to understand the kinematics and head injury risks of breakfall motion to design a more safe and effective judo teaching paradigm that results in reduction of injury risk. We aimed to investigate the biomechanics of judo backward breakfalls by comparing osoto-gari and ouchi-gari in novice judokas. Twelve male novice judokas (age: 21.3 years, SD?=?0.6 years; height: 1.74?m, SD?=?0.04?m; body weight: 71.3, SD?=?6.4?kg; body mass index: 23.5, SD?=?2.3) volunteered to participate in this study. The kinematic data of the breakfall motion for both osoto-gari and ouchi-gari were collected using a three-dimensional motion analysis technique (200?Hz). We observed significant differences between the movement patterns for the two techniques, especially in the lower extremity movements. In addition, a significantly greater peak extension momentum (osoto-gari: 1.29, SD?=?0.23?kg?m^2?s^?1; ouchi-gari: 0.84, SD?=?0.29?kg?m^2?s^?1) and lower head position along the vertical axis (osoto-gari: 0.18, SD?=?0.05?m; ouchi-gari: 0.31, SD?=?0.08?m) with a large effect size were found in the breakfall for osoto-gari. Our results suggest that a different paradigm is needed for effectively teaching each breakfall technique that will enable us to substantially lower the risk of judo-related head injuries in novice judokas.  相似文献

从理论宣传角度审视五四时期“问题与主义”之争     

葛传根 《信阳师范学院学报(哲学社会科学版)》2011,(3):11-14

20世纪初的＂问题与主义＂之争早已尘埃落定,但它所警告的教条主义空谈理论的危险并没有随之消失。＂问题与主义＂之争中提出的宣传＂主义＂和＂学理＂的方法,对我们今天的理论宣传仍有很大启发。  相似文献
