京津冀区域经济错位互补研究     

王翔宇 《廊坊师范学院学报》2013,(2):94-97

京津冀作为环渤海地区的核心区域,是我国最具经济活力的区域之一。目前,虽然京津冀区域经济发展取得了重大进展,但是,京津冀区域经济在错位互补发展方面仍存在不少问题。因此,京津冀区域间有必要建立政府协调机制和利益平衡机制;优化区域空间产业布局,促进区域经济错位互补发展;建立资源共享和信息传导机制,促进区域统一市场的形成;加快基础设施建设一体化,为区域经济发展保驾护航;建立生态保障共享机制,促进区域经济可持续发展。  相似文献

高水平游泳运动员肩关节损伤的特征   总被引：7，自引：1，他引：6  

刘明辉  雷芗生  黄力生 《体育学刊》2001,8(6):62-64

采用献资料、问卷调查、访问调查和数理统计，对1999年全国游泳冠军赛和锦标赛的18个省市代表队120名优秀运动员的肩关节损伤进行调查。结果显示：我国优秀游泳运动员肩关节损伤高达47.4％，且多为训练年限在6～9年的健将级以上运动员。患急性肩关节损伤多为主项爬泳、仰泳或蝶泳的。肩关节损伤的症状不同，治疗手段亦不尽相同。损伤的主要原因有局部训练负荷过重、训练水平不够、技术动作不合理等。针对肩关节损伤的发病原因、机理、症状，提出预防和治疗肩关节损伤的可行性建议。  相似文献

姚则会  赵磊 《成都教育学院学报》2014,(3):65-68

中国作为正在崛起的发展中大国,社会经济结构与就业结构正发生深刻变化,必然要求人才输出的高等教育因势而动。作为以地方财政为主要办学经费支持的省属综合性院校需要结合自身办学资源及服务面向的实际,深刻认识形势变化,明确办学理念和服务面向定位,对学校各专业进行合理分类,系统地开展专业建设的探索与实践,力求从培养方案、课程体系、教学内容、课内外实践环节、学业评价机制改革等方面,全方位地进行专业的应用性建设。  相似文献   

错位:高师中国现当代文学教学与中学语文教育   总被引：2，自引：0，他引：2  

杜运通  杜兴梅 《教育理论与实践》2006,(22)

中国现当代作家的作品在中学语文教材里占有举足轻重的地位,高师中国现当代文学教学与中学语文教育质量息息相关。但从目前的现状来看,二者在教材文本、教学内容和教学方法上存在着严重的错位现象。纠正这种错位现象,疏理高师和中学语文教育的通道刻不容缓。  相似文献   

优秀游泳运动员肩关节疼痛的主要病因分析——冈上肌肌腱炎     

陈寅  杨贤罡  刘阳 《辽宁体育科技》2014,(5)

优秀游泳运动员中肩部疼痛是常见现象,但其发病机理仍不完全清楚。冈上肌肌腱炎可能是导致肩部疼痛的主要病因,训练的强度和持续时间均能使肌腱增厚,产生撞击综合症,引发肌腱炎,导致疼痛,其发生机制可能与重复性应力刺激激活了蛋白激酶表达,使得细胞凋亡增加,导致肌腱炎和最终的退行性病变。  相似文献   

Does a water-training macrocycle really create imbalances in swimmers' shoulder rotator muscles?     

《European Journal of Sport Science》2013,13(2):167-172

Abstract

The continuous execution of swimming techniques may cause muscle imbalances in shoulder rotators leading to injury. However, there is a lack of published research studies on this topic. The aim of this study was to analyze the influence of a competitive swim period on the shoulder rotator–cuff balance in young swimmers. A randomized controlled pretest–posttest design was used, with two measurements performed during the first macrocycle of the swimming season (baseline and 16 weeks). Twenty-seven young male swimmers (experimental group) and 22 male students who were not involved in swim training (control group) with the same characteristics were evaluated. Peak torque of shoulder internal and external rotators was assessed. Concentric action at 1.04 rad s^?1 (3 repetitions) and 3.14 rad s^?1 (20 repetitions) was measured using an isokinetic dynamometer (Biodex System 3). External/internal rotators strength ratios were also obtained. For both protocols, there were significant training effects on internal rotator strength and external/internal rotator ratios (p ≤ .05). This trend was the same for both shoulders. Within-group analysis showed significant changes from baseline to 16 weeks for internal rotators strength and unilateral ratios of the experimental group. Swimmers' internal rotator strength levels increased significantly. In contrast, a significant decrease of the unilateral ratios was observed. Findings suggest that a competitive swim macrocycle leads to an increase in muscular imbalances in the shoulder rotators of young competitive swimmers. Swimming coaches should consider implementing a compensatory strength-training program.  相似文献   

Inter-session Reliability of Glenohumeral Internal and External Rotation Range-of-motion Measurements is Unaffected by Use of Applied Load Feedback     

Chris Grant  Tyson A. C. Beach  Sheilah Hogg-Johnson  Michael Chivers 《Measurement in physical education and exercise science》2020,24(1):81-92

ABSTRACT

This study evaluated whether real-time applied load feedback and a predefined applied load limit improved inter-session reliability and measurement error of passive glenohumeral rotation range-of-motion measurements. Twenty-one male recreational overhead athletes completed two data collection sessions, approximately 1-week apart. Measurements of internal and external rotation range-of-motion and clinician-applied loads were obtained and side-to-side differences were calculated. A load limit of 4 Nm was used for feedback trials. Perception of a capsular end-feel was used for no-feedback trials. Intraclass correlation coefficients (ICCs), standard errors of measurement (SEMs) and minimal detectable changes (MDCs) were derived. ICCs from single trials with and without feedback ranged from 0.72–0.93 and 0.63–0.89, respectively. SEMs ranged from 2.6°-6.1° with feedback and 3.3°-6.0° without feedback. MDCs from single trials with and without feedback ranged from 7.2°-16.8° and 9.1°-16.7°, respectively. Applied load feedback did not improve, already moderate to excellent, inter-session reliability and SEM for passive glenohumeral rotation range-of-motion measurements.  相似文献
