Abstract

This study was designed to assess the effects of a specifically designed perceptual-motor training program on the level of perceptual-motor development, self-concept, and academic ability of kindergarten children. Subjects for the study were 40 kindergarten children randomly assigned to 1 of 2 groups. Each group received the same kindergarten program with one exception, the experimental group was exposed to a specifically designed perceptual-motor program 30 min daily for 5 mo, while the control group received a free play period for 30 min daily. Results of the study indicated that the data tended to support the specificity of training concept. The variables showing the greatest change were the perceptual-motor tests which measured changes on specific aspects of the training program. There appeared to be some immediate transfer to academic abilities but this was not pronounced enough to suggest that perceptual-motor training was of real benefit in developing academic abilities for normal kindergarten children. In addition the follow-up test indicated no long term effects on academic performance.  相似文献   

Agreement in Body Fat Estimates Between a Hand-Held Bioelectrical Impedance Analyzer and Skinfold Thicknesses in African American and Caucasian Adolescents

Purpose: The aim of this study was to examine the effect of active versus passive recovery on 6 repeated Wingate tests (30-s all-out cycling sprints on a Velotron ergometer). Method: Fifteen healthy participants aged 29 (SD = 8) years old (body mass index = 23 [3] kg/m²) participated in 3 sprint interval training sessions separated by 3 to 7 days between each session during a period of 1 month. The 1st visit was familiarization to 6 cycling sprints; the 2nd and 3rd visits involved a warm-up followed by 6 30-s cycling sprints. Each sprint was followed by 4 min of passive (resting still on the ergometer) or active recovery (pedaling at 1.1 W/kg). The same recovery was used within each visit, and recovery type was randomized between visits. Results: Active recovery resulted in a 0.6 W/kg lower peak power output in the second sprint (95% confidence interval [CI] [ ? 0.2, ? 0.8 W/kg], effect size = 0.50, p < .01) and a 0.4 W/kg greater average power output in the 5th and 6th sprints (95% CI [+0.2,+0.6 W/kg], effect size = 0.50, p < .01) compared with passive recovery. There was little difference between fatigue index, total work, or accumulated work between the 2 recovery conditions. Conclusions: Passive recovery is beneficial when only 2 sprints are completed, whereas active recovery better maintains average power output compared with passive recovery when several sprints are performed sequentially (partial eta squared between conditions for multiple sprints = .38).  相似文献

宋彬蔚  李宗香  费红敏  冷显志  刘来喜  曹蓓娟 《体育科技文献通报》2013,21(4):96-98

为了解女大学生对体重、肥胖及对瘦身行为的认知情况,本文运用文献资料法、抽样调查法、问卷调查法、数理统计法等方法对师院女大学生的身体现状、肥胖观念、减肥认知等进行分析研究。结果显示,相对较大比例的湖北师女大学生在对自身肥胖定义和减肥方式选择等方面存在着诸多误区,本文针对这些误区提出了相关的可行性建议。  相似文献

Apocalyptic public health: exploring discourses of fatness in childhood ‘obesity’ policy     

《教育政策杂志》2012,27(1):3-22

ABSTRACT

Recent ‘obesity’ preventions focus heavily on children, widely regarded as the future of society. The National Child Measurement Programme (NCMP) is a flagship government programme in England that annually measures the Body Mass Index (BMI) of children in Reception (aged 4–5) and Year 6 (aged 10–11) in order to identify ‘at risk’ children and offer advice to parents. Using Foucauldian discourse analysis this study explores how discourses within the programme construct fatness. The NCMP materials contain three key interrelated themes (concerning the hidden threat of ‘obesity’, the burden of ‘obesity’, and bodies that pose a greater risk) that combine to construct a ‘grotesque discourse’ of apocalyptic public health. ‘Obesity’ is constructed as a social and economic catastrophe where certain bodies pose a greater threat than others. We argue that this discourse has the potential to change health service policy in markedly regressive ways that will disproportionately impact working-class, Black, Asian, and mixed race families.  相似文献

目的：评价超声测量内脏脂肪厚度对非酒精性脂肪性肝病（NAFLD）的诊断和分级的价值。方法：收集2010年8月至2011年4月在某院体检中心进行健康体检资料共122例,NAFLD组74例,非NAFLD组48例,经超声测量内脏脂肪厚度。结果：超声测量内脏脂肪厚度在NAFLD组和非NAFLD组之间差异有显著性统计学意义（P=0．004）。轻度、中度、重度NAFLD组测量的内脏脂肪厚度经方差分析结果为差异有统计学意义（F=9．91,P〈0．001）,进一步用LSD法分析显示两两之间都有差异。经超声测量的VFT诊断NAFLD的ROC曲线下面积为0．794,p=0．011,诊断切点值为2．70cm。结论：经超声测量的内脏脂肪厚度可作为NAFLD诊断和分级的指标。  相似文献   

Pupil Cheating: Study of Dishonesty in a School     

Lyle H. Johnson 《Clearing house (Menasha, Wis.)》2013,86(2):72-74

Health and fitness are important issues for high school administrators, teachers, and students. Obesity is a growing concern for all ages, and it is particularly relevant for adolescents because they are at a stage in which they may be establishing habits that will last a lifetime. It is also a critical problem at this level because there is frequently limited time for physical education in the high schools. High school faculty can have an important impact by serving as role models for students, reinforcing good health habits, integrating movement into their courses, collaborating with parents and professionals, and sharing ideas about community resources and activities with their students.  相似文献

田吉明  汪军  王瑞元 《北京体育大学学报》2008,31(11)

研究一次性运动对肥胖大鼠脂肪组织HSL、perilipin蛋白含量及脂肪水解的影响。方法:116只3周龄SD雄性大鼠,110只给予10周高脂饲料,建立高脂饮食诱导肥胖大鼠模型。随机分为:安静对照组,运动后即刻、1、31、2和24 h组。用化学法测试血清FFA和甘油、脂肪组织HSL活性;用Western Blotting法测试HSL和perilipin蛋白表达。结果:与对照组相比,运动后FFA和甘油、HSL活性和含量出现不同程度升高;而perilipin含量除即刻组出现显著升高外,其它各组均显著降低。结论:一次性运动导致肥胖大鼠运动后脂解增加,可能与其脂肪组织HSL活性、HSL蛋白含量上调及perilipin蛋白含量下调有关。  相似文献
