有关休闲体育的各种研究越来越多,但对休闲体育环境的建设却少有问津。良好的环境支撑是休闲体育可持续发展的必要条件,而休闲体育的良性发展也将优化环境。自然环境是休闲体育良性发展的根本,社会环境则是休闲体育良性发展的摇篮。建设良好的休闲体育环境是现今休闲体育亟需研究的重要课题。 相似文献

为检验中文期刊全文数据库实际收录年限与数据库商声明的收录年限是否相符以及相符程度如何,提出"收录年限相符度"的概念。以"中国学术期刊网络出版总库"、"中文科技期刊数据库"、"万方学术期刊数据库"为例,对"收录年限相符度"进行计算,三库"收录年限相符度"依次为:73.8%、31.7%、7.5%。对"收录年限相符度"两大影响因素的研究显示,三库均有一定比例的期刊应收未收,但更名刊处理方式对收录年限相符度影响不大。指出"收录年限相符度"便于用户准确把握数据库的收录年限,避免错误认知对图书馆工作的影响。 相似文献

To inform recruitment, selection, training and testing of male and female rugby sevens players game running movement patterns and physical characteristics were quantified across junior, senior, and elite playing levels. Anthropometric and physical testing (40 m sprint, vertical jump, Yo-Yo IR1) occurred prior to players’ national championships or international tournaments (n = 110 players), while game movements were obtained via GPS (n = 499 game files). The game movements of male players were similar across playing levels except for number of impacts >10 g which were 2 to 4-fold higher in elite (25.0 ± 11.2 impacts · game?1; mean ± SD), than junior (6.3 ± 3.5) and senior (11.8 ± 6.6) players. In men, there were fewer substantial correlations between on- and off-field measures which may reflect similar physical attributes across playing levels, and that other (strength, technical or tactical) factors may better differentiate these players. In females, elite players had more favourable on- and off-field performance measures than juniors and seniors, with moderate to strong correlations between on- and off-field variables. Female players should benefit from additional fitness training, while male players need to balance fitness with other technical and tactical factors. 相似文献
