Health-related fitness knowledge growth in middle school years: Individual- and school-level correlates

BackgroundHealth-related fitness knowledge (HRFK) has been an essential concept for many health and physical education programs. There has been limited understanding and longitudinal investigation on HRFK growth. This longitudinal study examined HRFK growth and its individual- and school-level correlates in middle school years under 1 curriculum condition: Five for Life.MethodsParticipants were 12,044 students from 47 middle schools. Data were collected at both individual/participant and school/institution levels. Individual-level variables included gender, grade, and HRFK test scores. School-level variables included percentage of students receiving free and reduced meals (FARM), student-to-faculty ratio for physical education, and school academic performance (SAP). We used hierarchical linear modeling to examine HRFK 3-year growth in relation to individual- and school-level correlates.ResultsThe average HRFK score at 6th grade for females was 42.81% ± 1.32%. The predicted HRFK growth was 17.06% ± 1.02% per year, holding other factors constant. A 1-standard deviation increase in FARM correlated with a 14.68%-point decrease in predicted test score (p = 0.02). A 1-standard deviation increase in SAP was associated with an 11.90%-point increase in HRFK score. Males had a significantly lower growth rate than females during the middle school years (0.78%/year, p = 0.02).ConclusionThe result showed that both individual- and school-level variables such as gender, FARM, and SAP influenced HRFK growth. Educators should heed gender differences in growth curves and recognize the correlates of school-level variables.

建设体育强国背景下体育经济重要地位及其发展策略

加快体育强国建设已成为一项国策,研究如何提高和建设可持续发展性的体育产业经济以解决人民日益增长的美好体育生活需要和不平衡不充分的发展之间的矛盾对建设体育强国具有重要意义。采用哲学辩证理论分析体育产业经济对体育强国构建的重要性,统计分析目前我国体育产业经济发展现状及其与发达国家的差距,结合十九大新时代背景下给出未来体育产业经济发展策略以期寻求为构建体育强国给出一些指导意见。认为：体育经济是体育强国的重要基石;开展全民健身运动、优化体育产业结构、政府政策导向市场化、跨产业融合增加与其他产业的结合度对构建体育强国具有重要的意义。     

新时代背景下武术与民族传统体育专业教育招生改革路径研究*

当前,学校体育改革进入破解新旧问题的攻坚期,仍需采用不同视角及理论对学校体育政策执行中的“跨域”现象予以新认识,发现新问题,提出新对策。研究从“条块关系”视角入手,运用文献资料、逻辑分析等方法,对学校体育政策执行中的“条块关系”特征（“条条”嵌入、“块块”统筹和“条块”整体）及问题（“条条”冲突、“块块”封闭和“条块”分割）进行解析,并结合整体性治理理念,提出重塑公共理念、加强制度建设、强化责任意识、培育信息共享和树立利益意识等对策,以期纾解“条块”问题,改善执行基础。     

Temporal trends in 6-minute walking distance for older Japanese adults between 1998 and 2017

BackgroundThe 6-minute walking distance (6MWD) is an excellent measure of both functional endurance and health. The primary aim of this study was to estimate temporal trends in 6MWD for older Japanese adults between 1998 and 2017; the secondary aim was to estimate concurrent trends in body size (i.e., height and mass) and self-reported participation in exercise/sport.MethodsAdults aged 65–79 years were included. Annual nationally representative 6MWD data (n = 103,505) for the entire period were obtained from the Japanese Ministry of Education, Culture, Sports, Science and Technology. Temporal trends in means (and relative frequencies) were estimated at the gender–age level by best-fitting sample-weighted linear/polynomial regression models, with national trends estimated by a post-stratified population-weighting procedure. Temporal trends in distributional variability were estimated as the ratio of coefficients of variation.ResultsBetween 1998 and 2017 there was a steady, moderate improvement in mean 6MWD (absolute = 45 m (95% confidence interval (95%CI): 43–47); percent = 8.0% (95%CI: 7.6%–8.4%); effect size = 0.51 (95%CI: 0.48–0.54)). Gender- and age-related temporal differences in means were negligible. Variability in 6MWD declined substantially (ratio of coefficients of variation = 0.89, 95%CI: 0.87–0.92), with declines larger for women compared to men, and for 75–79-year-olds compared to 65–74-year-olds. Correspondingly, there were moderate and negligible increases in mean height and mass, respectively, and negligible increases in the percentage who participated in exercise/sport at least 3 days per week and at least 30 min per session.ConclusionThere has been a steady, moderate improvement in mean 6MWD for older Japanese adults since 1998, which is suggestive of corresponding improvements in both functional endurance and health. The substantial decline in variability indicates that the temporal improvement in mean 6MWD was not uniform across the distribution. Trends in 6MWD are probably influenced by corresponding trends in body size and/or participation in exercise/sport.     

东京奥运会延期举办背景下东道主形象修复策略研究

中国茶叶国际竞争力分析与政策建议

本文运用FAO的统计资料，利用国际市场占有率、显示性比较优势、生产者价格指数3个显性评价指标和单产这个隐性评价指标，测算了20世纪80年代以来中国与印度、斯里兰卡、肯尼亚和印尼茶叶的国际竞争力变化。分析表明，中国茶叶在4个评价指标上基本处于劣势地位,尤其表现在显示性比较优势、生产者价格指数和单产3个指标上。本文基于波特教授的“国家钻石”模型中国际竞争力的5个决定因素，提出提升中国茶叶国际竞争力的相应对策与建议:①在要素禀赋层面，重点解决低下的要素的生产率问题，要创造新的生产要素并将之导入茶叶产业;②在公司层面，要顺应国际茶叶竞争潮流，推行联合规模经营，走名茶名牌之路;③在关联产业层面，要积极发展专业化生产，为茶叶生产提供专业性的生产资料;④在需求层面，要在稳固传统市场的基础上，大力开拓新兴市场，降低出口市场的集中度;⑤在政府层面，要明确在WTO框架下的职能边界，重点解决好茶叶的标准化问题，从源头和末端对混乱的茶叶出口秩序进行有效的治理。与其它4个层面相比，对茶叶产业而言，政府的行为可能更为关键，因为中国的实际情况决定了这一点。     

国家安全视域下宗教在高校的传播及对大学生的影响研究

宗教在我国具有悠远的传播历程,宗教中的优秀内容和丰厚的艺术积淀也一度为中华文明的发展提供了良好的借鉴。但宗教传播从一开始就泥沙俱下,和平时期亦是屡见不鲜。高校作为大学生思想政治教育工作的重要阵地和平台,必须从国家安全的视域下,明辨宗教在学生中传播的优劣,在维护国家宗教政策的同时,摒弃不良影响和可能危害国家安全的内容,培养出更多有学识、有担当的社会主义合格建设者。     

抗战前南京国民政府土地立法的进程
