乡村民俗体育文化综合评价体系的研究

乡村生活的现代化使乡村民俗体育文化的生存环境恶化,因此有必要采取有力措施对乡村民俗体育文化进行保护。从民俗体育项目的普查、筛选与评测到保护的实施再到反馈,各个环节都不容忽视。民俗体育文化的保护需要找到科学系统的体系,又能得到国内外公认的操作办法,因此,有必要建立起乡村民俗体育文化的综合评价体系。     

Comparison of different theoretical models estimating peak power output and maximal oxygen uptake in trained and elite triathletes and endurance cyclists in the velodrome

Abstract

The primary objective of this study was to examine the relationship between heart rate intensity and pedometer step counts in adolescents. To determine cardiorespiratory fitness, 106 participants (47 boys, 59 girls, mean age 14.2 years, s = 0.8) completed the Queen's College Step Test and were classified as having low, moderate or high cardiorespiratory fitness. Adolescents also completed a 10-min treadmill trial while wearing a pedometer and heart rate monitor. The participants were instructed to maintain their heart rate between 65 and 75% of their maximum heart rate while running or walking on a treadmill. A heart rate of 65–75% maximum was associated with 146 steps per minute (s = 22) in boys and 137 steps per minute (s = 22) in girls. Results of analysis of variance indicated that there was a main effect for level of fitness (F _2,102 = 9.36, P < 0.001). The correlation between mean steps per minute and estimated maximum oxygen consumption was statistically significant (r = 0.44, P < 0.001). The results from this study suggest that a step rate of 130 steps per minute is equal to 65–75% maximum heart rate in low-fit adolescents and achieving 130 steps per minute could be used as an initial goal to improve fitness.     

Laboratory versus field testing in cricket bowling: A review of current and past practice in modelling techniques

In cricket bowling, the reconstruction of elbow angle data is of utmost importance to the bowling versus throwing argument. This paper reviews system and modelling errors inherent in three-dimensional reconstruction processes with respect to the elbow extension tolerance set by the International Cricket Council. An understanding of these factors will enable more informed decisions about the choice of in-field versus laboratory testing in the calculation of elbow extension during bowling in cricket. Although there is a paucity of objective data related to in-field and laboratory testing, biomechanists must be guided by the greater accuracy of opto-reflective than video-based systems and so testing, at least for the present, should be conducted in a laboratory setting.     

日本终身学习体系构建的保障及其启示

上世纪70年代左右,终身教育和终身学习理念的相继提出给世界各国发展教育提供了新的视野。日本终身教育在四十多年发展过程中积累了丰富的理论和实践经验,走在了亚洲甚至是世界的前列。因此,探讨日本终身学习体系构建的保障,从法律法规体系、机构设施体系和财政投入体系三方面进行解析,对我国构建和发展终身教育有借鉴作用。     

System Analysis for Oxygen Uptake Kinetics with Step and Pseudorandom Binary Sequence Exercise in Endurance Athletes

We examined whether the system analysis for step and pseudorandom binary sequence (PRBS) exercises could be useful to characterize oxygen uptake (VO₂) kinetics of female sedentary subjects and endurance athletes. Breath-by-breath VO₂ was determined during step- and PRBS-cycle ergometer exercises. The time course of the VO₂ kinetics was evaluated by the time constant of the second phase, which should reflect the adjustment of the oxidative metabolism at the skeletal muscle level. The VO₂ kinetics were significantly faster in long-distance runners than in sedentary subjects for both exercises. A significant relationship was observed in the VO₂ kinetics obtained from step and PRBS exercises. In each group, there was no significant difference in the VO₂ kinetics for step and PRBS exercises. These results indicated that the system analysis with PRBS exercises revealed the faster VO₂ kinetics in endurance athletes than in sedentary subjects.     

如何把握经济责任审计中的校长负责制

“党委领导下的校长负责制”是当前法定的高校管理体制,校长、书记这两个高校的“一把手”都是高校领导干部经济责任审计的审计对象,审计内容的侧重、问题责任的区分是高校领导干部经济责任审计的难点。“党委领导下的校长负责制”的法定含义,是解决这一审计难点的有效途径。     

基于CBR的网球技战术信息系统研究——以双手反拍为例

近年来,学者对网球运动技术的研究越来越多,但是对于网球技战术信息系统的研究和开发较少。本文通过对CBR应用于计算机辅助处置网球比赛中技战术运用行为的分析,设计了一个基于案例推理的网球技战术信息系统模型,即通过对案例库中记忆的网球技战术进行相似性搜索,在分析网球技战术实施方案的各项内容及实施后收到的效果的基础上,对目标行为的预案进行决策支持。     

中国体育制度之伤--《李元伟篮坛风云路》和《忠诚无悔：我与中国足球》的对比思考

通过对中国篮坛和足坛前掌门人李元伟与阎世铎的传记(《李元伟篮坛风云路》和《忠诚无悔：我与中国足球》)从上任与卸任、与媒体打交道、外教及执教环境以及危机处理4个方面的对比分析,得出以下结论：1)“民间传言+私露口风+正式委任”的任命机制,存在太多主观因素,从长远看不利于篮球、足球发展;2)“管办不分”一定程度上阻碍了篮、足球职业化改革进程;3)篮、足球管理仍以“人治”为主,缺乏“法制”根基。我国足球、篮球运动发展的不同轨迹表明,在改革中谋求发展,在发展中推进改革,是中国体育体制改革必由之路。     

阳光体育视野下高校体育课程价值取向及构建

本文通过分析我国关于开展阳关体育运动的有关规定和政策,在高校体育课程设置和建构过程中,从强调个体兴趣和需要的满足,以及人的自我实现的达成,进而实现有较强的个人倾向的、稳固的价值取向,为构建全面、综合、发展的体育课程结构模式和过程规范化、管理科学化的课程体系和评价体系提供一些参考,也为高校学生的身体健康和参与体育锻炼的提供一些指导。
