我国重点城市U13男子足球运动员的神经类型和反应时的研究     

段再复  孟妍 《辽宁体育科技》2012,34(4):42-45

选取我国重点城市U13足球比赛的15支队伍中的206名男子运动员作为研究对象,对其神经类型和反应时进行了测定和分析,结果表明:参加我国重点城市U13足球比赛的运动员中有50％的运动员为优秀神经类型,适合于从事体育运动;13岁组和训练年限较多组中的优秀神经类型所占的比例较大,说明随着年龄的成熟和训练的深入,神经过程会得到优化;不同年龄、训练年限、神经类型的个体在反应时上无差异,选择反应时短的运动员并不能反映其具有较优秀的神经类型.  相似文献   

有氧运动对大鼠海马神经元BDNF表达的影响     

杨尚明  李红 《四川体育科学》2012,(4):28-31

本文意在通过观察适宜游泳运动后大鼠海马脑源性神经营养因子(BDNF)表达的变化,探讨有氧运动促进大脑健康的神经生物学机制。研究将24只SD大鼠随机分为对照组和运动组,运动组又分为3,7,12天三个亚组。采用SABC免疫组化染色法观察分析海马CA1区神经元BDNF阳性表达的数量。结果表明CG大鼠海马有BDNF阳性细胞的蛋白表达,并以神经元表达为主。与CG相比,7SG大鼠海马CA1区BDNF阳性细胞数量增加达显著水平(P<0.05),12SG大鼠海马CA1区BDNF阳性细胞数量增加达极显著水平(P<0.01)。因此,适量的有氧运动可增加BDNF的表达,促进大脑神经可塑性。  相似文献   

少年和成年业余长跑运动员急性耐力运动后心脏自主神经恢复观察研究     

黄传业  田野  聂金雷 《体育科学》2012,32(9):11-16

目的:观察少年和成年男子业余跑运动员一次急性耐力运动后心率变异(HRV)变化特征,并探讨运动后HRV变化生理学意义。方法:少年(14.4±1.3岁)与成年(25.7±2.8岁)受试者各10名,进行1次90min、强度为95%个体无氧阈强度跑台运动。在运动前、运动后15min以及运动后6h测定HRV。结果:运动后15min,TPLn、HFnu和HRV各时域指标明显低于运动前水平,LFnu和LF/HF显著升高;少年受试者HFnu降幅、LFnu和LF/HF升幅明显低于成年受试者(P<0.05)。运动后6h,HRV各指标均已恢复,其中,TPLn、SDNN、HFnu和RMSSD有反弹的迹象。运动后HFnu相对运动前的降幅与受试者年龄呈负相关关系(r=-0.645,P<0.01,n=20);另外,HFnu、TPLn相对运动前降低程度与运动前水平高度负相关(P<0.05,n=20)。结论:一次急性耐力运动后HRV出现短暂抑制现象,少年受试者运动后HRV降低幅度相对成年较低,可能与发育成熟度不同有关,急性运动后HRV变化可能是运动适应的生理表现。  相似文献

Rites of Passage: Does adaptation to university mean severing connections?     

Wardley  Leslie  Bélanger  Charles 《Tertiary Education and Management》2013,19(1):32-51

Many factors go into the decision of selecting a university, ranging from the overall costs and the programme of study to the institute’s reputation; however, accommodation while at university and proximity of the university to one’s permanent abode also play important roles in this decision-making process. Thus, first-year students experience different stages of separation from their prior networks depending on their individual situations. The results of this Ontario (Canada) 2012 study add to prior research by indicating that separation of students’ living arrangements and distance from home impact on transition and incorporation variables, which influenced students’ adaptation to university.  相似文献   

Conceptions of quality in four different disciplines     

Ole‐Jacob Skodvin 《Tertiary Education and Management》2013,19(1):65-80

Abstract

The paper is based on a book (written by the author and his colleague Markku Lehikoinen) dealing with definitions of quality and views on the applicability of different methods of quality assessment to four different disciplinary fields: physics, biology, sociology and history. The paper focuses on conceptions and definitions of quality voiced by scholars representing the different disciplines. The study involved semi‐structured in depth interviews with 33 experienced scholars. The disciplines under study were chosen to represent diverse disciplinary cultures, with the aim of finding out about the potential impact of (social and cognitive) cultural characteristics of the disciplines on conceptions of quality. The findings show both common views across disciplinary fields and disciplinary differences.  相似文献   

浅议人才测评在医学院校人才招聘中的应用     

蒋明思  张万信 《鸡西大学学报》2013,(6):10-12

医学院校在人才招聘中使用人才测评技术是为了实现人事相宜、人尽其才、才尽其用的目标,但目前医学院校对人才测评技术的使用结果还不理想,存在诸多问题:人才测评要素不全;测评方法传统单一,缺乏科学性;人才测评专业化不高,缺乏创新等。医学院校在人才招聘工作中要科学、客观、合理地运用人才测评技术,全面制定人才测评要素;使测评方法多样化,实现人才测评合理化、专业化和规范化,提高创新能力。  相似文献

Assessment of Middle Ear Anatomy Teaching Methodologies Using Microscopy versus Endoscopy: A Randomized Comparative Study     

Lukas Anschuetz  Sören Huwendiek  Daniel Stricker  Abraam Yacoub  Wilhelm Wimmer  Marco Caversaccio 《Anatomical sciences education》2019,12(5):507-517

Teaching methodologies for the anatomy of the middle ear have not been investigated greatly due to the middle ear’s highly complex structure and hidden location inside of the temporal bone. The aim of this randomized study was to quantitatively compare the suitability of using microscope- and endoscope-based methods for teaching the anatomy of the middle ear. We hypothesize that the endoscopic approach will be more efficient compared to the microscopic approach. To answer the study questions, 33 sixth-year medical students, residents and otorhinolaryngology specialists were randomized either into the endoscopy or the microscopy group. Their anatomical knowledge was assessed using a structured anatomical knowledge test before and after each session. Each participant received tutoring on a human cadaveric specimen using one of the two methods. They then performed a hands-on dissection. After 2–4 weeks, the same educational curriculum was repeated using the other technique. The mean gains in anatomical knowledge for the specialists, residents, and medical students were +19.0%, +34.6%, and +23.4%, respectively. Multivariate analyses identified a statistically significant increase in performance for the endoscopic method compared to the microscopic technique (P < 0.001). For the recall of anatomical structures during dissection, the endoscopic method outperformed the microscopic technique independently of the randomization or the prior training level of the attendees (P < 0.001). In conclusion, the endoscopic approach to middle ear anatomy education is associated to an improved gain in knowledge as compared to the microscopic approach. The participants subjectively preferred the endoscope for educational purposes.  相似文献
