我国大学生体质监测管理模式的重构          下载免费PDF全文

赖锦松 《河北体育学院学报》2016,30(4):47-52

我国现行的大学生体质监测管理模式分为行政统筹型和高校自主型两类,其实效性明显不足,为实现管理工作的长效规范和切实增进大学生体质健康,迫切需要重构大学生体质监测管理模式.认为,应在现状基础上构建三级、分类、联网的大学生群体体质监测管理模式和标准化投入、规范化监测、人性化服务相结合的大学生个体体质监测管理模式,并在国家、省、高校之间规范机构设置,完善机构职能,建立质量评估体系,提高运行效率,完善保障措施,落实服务与干预,以促进大学生体质监测管理工作取得实效.  相似文献   

A new footwear technology to promote non-heelstrike landing and enhance running performance: Fact or fad?     

Janet H. Zhang  Aislinn J. C. McPhail  Winko W. An  Waqar M. Naqvi  Daniel L. H. Chan  Ivan P. H. Au 《Journal of sports sciences》2017,35(15):1533-1537

This study sought to compare the kinetics and kinematics data in a group of habitual shod runners when running in traditional running shoes and newly designed minimalist shoes with lug platform. This novel footwear design claims to simulate barefoot running and reduce energy loss during impact. We compared footstrike angle (FSA), vertical average (VALR) and instantaneous (VILR) loading rates, energy loss and initial vertical stiffness between two shoe conditions. Runners demonstrated a decreased FSA while running in minimalist shoes with lug platform than traditional shoes (P = 0.003; Cohen’s d = 0.918). However, we did not observe a landing pattern transition. VALR and VILR between two footwear conditions showed no significant difference (P = 0.191–0.258; Cohen’s d = 0.304–0.460). Initial vertical stiffness (P = 0.032; Cohen’s d = 0.671) and energy loss (P = 0.044; Cohen’s d = 0.578) were greater when running in minimalist shoes with lug platform. The results show that minimalist shoes with lug platform reduce the FSA but may not lead to a landing pattern switch or lower vertical loading rates. Interestingly, the new shoe design leads to a greater energy loss than traditional running shoes, which could be explained by a higher initial vertical stiffness.  相似文献   

基于波束扫描的DBF天线方向图测试方法     

周建卫  李道京  胡烜 《中国科学院大学学报》2016,33(4):542-547

DBF天线安装后，一般不具备可机械旋转的常规测试条件。研究DBF天线方向图的间接测试问题，提出一种基于波束扫描的测试方法，给出其测试原理和测试流程。针对波束宽度、副瓣水平和波束指向等天线主要参数，用仿真比对该方法与常规方法的测试结果和误差。在DBF天线方向图正常和异常两种情况下，两种方法可得到相近的仿真测试结果，证明间接测试方法的有效性。  相似文献

Neuro-mechanical adjustments to shod versus barefoot treadmill runs in the acute and delayed stretch-shortening cycle recovery phases     

Cedric Morio  Violaine Sevrez  Pascale Chavet  Eric Berton  Caroline Nicol 《Journal of sports sciences》2016,34(8):738-745

In habitually shod recreational runners, we studied the combined influence of footwear and stretch-shortening cycle (SSC) fatigue on treadmill running pattern, paying special attention to neuro-mechanical adjustments in the acute and 2-day delayed recovery periods. The SSC exercise consisted of a series of 25 sub-maximal rebounds on a sledge apparatus repeated until exhaustion. The acute and delayed functional fatigue effects were quantified in a maximal drop jump test. The neuro-mechanical adjustments to fatigue were examined during two submaximal treadmill run tests of 3 min performed either barefoot or with shoes on. Surface electromyographic (EMG) activities, tibial accelerations and kinematics of the right lower limb were recorded during the first and last 15 s of each run. The main result was that neuro-mechanical differences between the shod and barefoot running patterns, classically reported in the absence of fatigue, persisted in the fatigued state. However, in the delayed recovery phase, rearfoot eversion was found to significantly increase in the shod condition. This specific footwear effect is considered as a potential risk factor of overuse injuries in longer runs. Therefore, specific care should be addressed in the delayed recovery phase of SSC fatigue and the use of motion control shoes could be of interest.  相似文献   

维吾尔语动词动元的配价研究     

关靥旻 《喀什师范学院学报》2007,28(2):52-56

维吾尔语是典型的有形态标志的语言,与动词联系的从属成分一定有“格”的标志,这种形态变化就决定了这些从属成分特定和相对应的句法位置及语义关系。动词和从属成分之间的选择关系十分复杂,直接影响着动词的分类。论文用配价理论来分析研究维吾尔语动词是如何跟其他成分发生关系的,动词“价”的分类以及动词和“价”同现的条件。这将有利于研究维吾尔语动词次类的划分,从而进一步揭示维吾尔语动词的内在规律和特点。  相似文献
