试论我国《体育法》的修改、完善   总被引：6，自引：1，他引：5  

蒙雪  黄明 《天津体育学院学报》2003,18(4):72-74

《中华人民共和国体育法》作为我国体育基本法于1995年8月29日颁布以来，发挥了重大的作用。但随着时代的变迁以及《体育法》受“宜粗不宜细”立法思想的指导，本身存在许多缺陷，以至愈来愈不能满足我国体育事业发展过程中对法的需求。因此，修改、完善《体育法》势在必行。运用立法法、行政法、比较法的基本原理对我国《体育法》存在的问题作逐一分析，并在此基础上提出修改《体育法》的具体意见。  相似文献

第25届奥运会女子高低杠规定动作主要难度的运动学分析     

俞继英  邹亮畴  郊耘  钟冶 《上海体育学院学报》1991,(3)

本文利用计算机解析系统,对第25届奥运会女子高低杠规定动作中的主要难度动作的参数进行了运动学定量分析。解析结果表明,由面对低杠的高杠倒立开始的大摆动作,屈髋(腿加速)开始于过杠垂面之前,这与传统的摆动动作技术原理相悖。  相似文献   

Cerebral activity prior to motion task performance: an electroencephalographic study     

D Collins  G Powell  I Davies 《Journal of sports sciences》1991,9(3):313-324

Cerebral activity, as reflected by power in the alpha waveband (8-13 Hz), was examined prior to the performance of three tasks with different effort and accuracy requirements. The study aimed to further investigate changes in activity observed in an earlier study in which expert karate performers exhibited significant increases in alpha band power during preparation for a training task. In contrast to the earlier research, the high effort task produced a significant decrease in 'alpha' power prior to performance. 'Alpha' power prior to the high accuracy task showed significant differences mediated by the outcome. Successful performance was preceded by higher levels of 'alpha' power than unsuccessful attempts. The reported use of a cognitive strategy on the first task produced a significant difference in activity, lower alpha power being associated with the use of such a technique.  相似文献   

Postexercise energy expenditure following upper body exercise     

D A Sedlock 《Research quarterly for exercise and sport》1991,62(2):213-216

This study was designed to examine the magnitude and duration of excess postexercise oxygen consumption (EPOC) following upper body exercise, using lower body exercise for comparison. On separate days and in a counterbalanced order, eight subjects (four male and four female) performed a 20-min exercise at 60% of mode-specific peak oxygen uptake (VO2) using an arm crank and cycle ergometer. Prior to each exercise, baseline VO2 and heart rate (HR) were measured during the final 15 min of a 45-min seated rest. VO2 and HR were measured continuously during the postexercise period until baseline VO2 was reestablished. No significant difference between the two experimental conditions was found for magnitude of EPOC (t [7] = 0.69, p greater than .05). Mean (+/- SD) values were 9.2 +/- 3.3 and 10.4 +/- 5.8 kcal for the arm crank and cycle ergometer exercises, respectively. Duration of EPOC was relatively short and not significantly different (t [7] = 0.24, p greater than .05) between the upper body (22.9 +/- 13.7 min) and lower body (24.2 +/- 19.4 min) exercises. Within the framework of the chosen exercise conditions, these results suggest EPOC may be related primarily to the relative metabolic rate of the active musculature, as opposed to the absolute exercise VO2 or quantity of active muscle mass associated with these two types of exercise.  相似文献   

CONCERN FOR THE ENVIRONMENT: A CROSS-NATIONAL PERSPECTIVE     

Skrentny  John D. 《Int. Journal of Public Opinion Research》1993,5(4):335-352

Data from the International Social Survey Program indicate considerablevariation in the desire of respondents for increased spendingon the environment in Australia, Austria, Great Britain, theUnited States, and West Germany. This paper explores this variationwith the following objectives: (1) to determine the extent towhich the social bases of environmental concern are consistentacross nations; (2) to determine how the issue of the environmenthas been politicized in the five industrialized nations, focusingon the association of Old Leftist concerns and environmentalconcern; and (3) to determine the extent to which the socialbases of environmental concern can explain the cross-nationalvariation. The study usesa regression analysis, testing variablesrepresenting the social bases of environmental concern frompast research in the United States, a scale representing commitmentto the platform of the Old Left, and dummy variables for eachcountry. The results show that the social bases of environmentalconcern are the same in the five countries studied, includinga consistent positive association of Old Leftism with environmentalconcern. However, substantial variation between countries inthe overall level of concern remains. Potential sources of theremaining variation are examined.  相似文献
