通过对福建省十所普通高校的肥胖大学生课外体育活动的现状进行调查与分析，结果表明：肥胖大学生参加课外体育活动的主要动机是想减肥健身、提高身体素质和娱乐身心等，但实际课外体育活动的现状不尽如人意，被调查参加课外体育活动3次/周以上仅占13.3％，每次运动时间30min以上仅占68.3%，且所选择的活动项目比较单一，缺少一些针对性的内容，也缺乏适宜运动强度的知识，难以达到减肥的效果。肥胖自身存在的问题、缺少场地器材、学习紧张、余暇时间少、缺少理论知识与实践指导、缺少伙伴、缺乏组织管理等是造成肥胖大学生课外体育活动现状不佳的主要因素，结合现状提出改善肥胖大学生课外体育活动现状相应的对策。 相似文献

The purpose of this study was to examine the mediating effect of resistance training skill competency on percentage of body fat, muscular fitness and physical activity among a sample of adolescent boys participating in a school-based obesity prevention intervention. Participants were 361 adolescent boys taking part in the Active Teen Leaders Avoiding Screen-time (ATLAS) cluster randomised controlled trial: a school-based program targeting the health behaviours of economically disadvantaged adolescent males considered “at-risk” of obesity. Body fat percentage (bioelectrical impedance), muscular fitness (hand grip dynamometry and push-ups), physical activity (accelerometry) and resistance training skill competency were assessed at baseline and post-intervention (i.e., 8 months). Three separate multi-level mediation models were analysed to investigate the potential mediating effects of resistance training skill competency on each of the study outcomes using a product-of-coefficients test. Analyses followed the intention-to-treat principle. The intervention had a significant impact on the resistance training skill competency of the boys, and improvements in skill competency significantly mediated the effect of the intervention on percentage of body fat and the combined muscular fitness score. No significant mediated effects were found for physical activity. Improving resistance training skill competency may be an effective strategy for achieving improvements in body composition and muscular fitness in adolescent boys. 相似文献

为促进超重和肥胖大学生积极参与体育锻炼,有效提高大学体育教学质量,以文献资料、问卷调查法对湖南省高校390名肥胖大学生的身体发育状况和体育态度、体育行为现状进行调查分析。结果表明：被调查的肥胖大学生体育态度基本处于低水平,极少甚至不参加课余体育锻炼。提出在体育教学设计中应区别对待超重和肥胖大学生,有针对性的提高其体育态度的认知成分水平。 相似文献

采用测试法、询问法和数理统计法,对三明市高校高级知识分子身体质量指数及相关影响因素进行研究．结果表明：高级知识分子超重、肥胖的现象已较为严重,而且在超重、肥胖的趋势上男性要大于女性．超重肥胖现象主要与高级知识分子日常的饮食习惯和体育锻炼不足有关,也与工作性质有一定的关系． 相似文献

目的在于通过运动和心理健康干预辅以行为矫正来对超重和肥胖大学生进行干预,探讨超重和肥胖大学生身体素质及心理健康干预的方法和效果。采用心理症状自评量表(SCL-90)和大学生体质测试等研究工具,通过搜集、整理青岛农业大学422名超重和肥胖学生的体质健康测试数据,对肥胖和超重学生的心理健康水平与其体质状况的相关性进行了多重比较和分析,探讨系统的运动与心理干预对超重和肥胖大学生产生的效果及其机制,预防超重向肥胖转化和对既成肥胖的大学生进行运动与心理健康干预。 相似文献

有关"过负"问题的研究,浩瀚无穷,但它是一个概念,还是一个判断,则始终没有提出过。这个缺失,直接制约了减负研究的深入,对减负政策及其实践都带来不利影响。本文认为,"过负"是概念与判断的复合体,但首先应作为一个概念来揭示,因为它应对着一种独立的社会现象和教育现象,它不是能在"课业""学业"或"课程"范畴中,可加以揭示和刻画的现象或问题。"过负"内涵,可以归结为四点:外驱化、高压化、片面化和高耗化。相应地,减负直接目的或目标由此归结为三个:保护或维护好儿童的身心材质这一民族的最根本的天赋资源;保障和落实儿童权利和权益;给儿童或学生留出自我发展或自主发展的必要时空。减负的这三大目的或目标,同时也体现为向"建设现代社会和现代教育"这一最终目标的努力和驱近。 相似文献

运用体质指数法、皮褶厚度法及生物电阻抗法,判断上海城区儿童青少年超重、肥胖发生率及其一致性。结果显示:3种方法在判断不同年龄、性别儿童青少年超重、肥胖上一致性较低;测量原理与精确性不同,青少年儿童体成分化学组成不成熟及诊断、筛查标准的差异可能是3种方法一致性较低的原因。提出应建立适合我国儿童青少年"多维模型"假设下的体脂率预测方程。 相似文献

This cross-sectional study analysed the association of sedentary behaviour (SB) and standing with waist circumference. Finnish adults aged 30-75 years from a sub-sample of population-based Health 2011 Study used a hip-worn tri-axial accelerometer (Hookie AM20, Traxmeet, Ltd, Espoo, Finland) for seven days. Those 1405 participants (57% women) who used accelerometer at least four days, minimum of 10 hours/day, were included. SB and standing were analysed in 6s epochs using validated algorithm. Daily total time, daily number and accumulated time from bouts (30s–5min,30s–10min,30s–15min,30s 30min,>5min,>10min,>15min, >30min) as well as daily number of sit-to-stand transitions were determined. Waist circumference (cm) was measured in standardized way. Participants’ mean age was 52 years (SD 12.2). Mean waist circumference was 97cm (SD 12.3) in men and 87cm (SD 12.7) in women. According to multivariable stepwise linear regression analysis, sit-to-stand transitions [standardised regression coefficient (β)= -0.14, 95%CI -0.20 to -0.09], standing bouts of 30s–5min (β= -0.21, 95%CI -0.26 to -0.15) and number of 30s-30min SB bouts (β=0.12, 95%CI 0.06 to 0.17) were most strongly associated with waist circumference. Besides assessing total SB time, future studies should assess also different bout lengths of SB and sit-to-stand transitions and standing times should be assessed separately. 相似文献

目的:基于决策树模型探讨引起幼儿超重的关键因素。方法:招募南昌市23所幼儿园5870名3~6岁幼儿,测量身高、体重;问卷调查幼儿身体活动、静坐行为、出生信息,父母的育儿方式、身体形态、锻炼行为和家庭情况,并将其划分为36个变量;采用IBM SPSS modeler软件创建CHAID决策树模型,筛选幼儿超重的关键性因素。结果:CHAID模型准确率达85.23%。CHAID模型结果显示,8个变量与幼儿超重有较强关联性,各变量按重要性排序依次为室外身体活动时间、父亲BMI、母亲BMI、父亲收入、室内身体活动时间、父亲受教育程度、喂养方式、看电视时间。结论:身体活动尤其是室外身体活动与幼儿超重的关系最为密切,父母肥胖程度、父亲收入与受教育情况、喂养方式、静坐行为也是导致幼儿超重的关键性因素。 相似文献
