不同收入的城镇居民对体育消费结构和体育消费需求的影响*     

于〓乐  程〓蕾 《广州体育学院学报》2019,(5):26-30

采用问卷调查和数理统计方法,研究了不同收入的居民对体育消费结构和体育消费需求的影响。结果表明,随着居民收入的增加,各类体育消费都呈现上升趋势,实物型体育消费增长速度变慢,观赏型体育消费和健身型体育消费增长速度变快,当居民年收入在10万以上时,观赏型体育消费和健身型体育消费开始急剧增加。制约体育消费需求的主要因素是居民的收入、体育消费的价格、体育消费结构和居民的可支配时间。  相似文献   

馆校协同教学:馆校合作教学模式的理论探索     

王乐  涂艳国 《北京广播电视大学学报》2017,22(5)

当前场馆与学校的联系还停留在偶然性的场馆参观和随意性的校内展览,亟待寻得一种科学、便捷、可行的馆校合作模式.馆校协同教学是以"一般学习结果理论"的五维价值为核心的,场馆资源系统与学校教学系统可协同运作的合作模式和理论体系,其包括知识与理解,技能,态度与价值观,娱乐性、启发性和创新性,活动、行为和成长五方面内容.同时,馆校协同教学还表现出目的性、开放性和民主性三方面的教育规定性.活动范式上,它又包括物理参与、情感参与、智识参与和社交参与四种类型.  相似文献   

传统运动养生文化对城镇社区体育锻炼的影响     

张国梁  蔡峰  张乐  李静 《四川体育科学》2017,(1)

在中国几千年的历史发展中,运动养生文化能滋生繁衍、常青不衰,有其自身的存在价值.着重探讨中国传统运动养生文化对现代社会社区体育锻炼的影响,是为了更好地继承与弘扬中国传统运动文化,继而为社区居民体质的提高和体育锻炼发展,提供宝贵的运动养生资源.讨论在城镇化进程加快的过程中,社区居民单一的生活和休闲方式,还有社区体育锻炼缺乏等方面,运用运动养生进行体育锻炼能有效增强社区居民的体质健康和丰富居民的生活方式.  相似文献

Steps counts among middle school students vary with aerobic fitness level     

Le Masurier GC  Corbin CB 《Research quarterly for exercise and sport》2006,77(1):14-22

The purpose of this study was to examine if steps/day taken by middle school students varied based on aerobic fitness classification. Middle school students (N = 223; 112 girls, 111 boys) were assigned to three aerobic fitness categories (HIGH, MOD, LOW) based on results of the FlTNESSGRAM PACER test. Four weekdays of pedometer monitoring determined activity levels (steps/day). Boys accumulated significantly more steps/day than girls, 11,589 +/- 3,270 and 10,232 +/- 2,517 steps/day, respectively; F(1,219) = 16.0, p < .001, eta2 = .055. There were no differences in steps/day between grades. HIGH fit participants accumulated significantly more steps/day, F(2, 217) = 12.2, p < .101, eta2 = .101, than moderately fit and low fit participants (approximately 1,491 and ; 2,867 steps/day, respectively). Middle school students who participated in sports in addition to physical education (PE) accumulated significantly more steps/day (approximately 980 steps/day) than those participating in PE only, F(1, 219) = 10.0, p < .01, eta2 = .044. Although the relationship between physical activity and aerobic fitness was moderate (0.35; p < .01), these data demonstrated significant differences in accumulated steps/day among youth of varying aerobic fitness levels. Whether improved fitness levels were the result of additional activity or the cause of it remains to be determined. Regardless, the fittest middle school students were also the most active and accumulated a significant amount of steps/day through organized extracurricular physical activities.  相似文献

CERN document server: Document management system for grey literature in a networked environment     

Martin?VeselyEmail author  Thomas?Baron  Jean-Yves?Le?Meur  Tibor?Simko 《Publishing Research Quarterly》2004,20(1):77-83

Conclusion In this paper we briefly described the current status of research in the field of digital libraries interoperability, mainly with respect to federated data processing such as permitted within the Open Archive Initiative framework. We then presented the CERN Document Server Software suite that is a free software package main-tained by CERN providing an online digital library solution for mid- to large-sized document repositories. The set of CDSware modules was described and the differ-ences with other existing tools briefly mentioned. Finally we have mentioned a typical usage statistics illustrating the scope of grey literature and networked con-ditions of the CERN Document Server. We pointed out that the current trend in grey literature management goes toward institutional repositories build upon the distributed and federated model. Further research is going on within the CDS collaboration in this area, focused particularly on (i) semantic interoperability using ontologies in distributed and federated data processing and (ii) ranking technologies when searching grey literature in OAI compliant repositories.  相似文献
