对四川省手球运动员关节肌力训练的实验研究     

张和莉  田虹  潘建武  李小蓉 《成都体育学院学报》1996,(4)

】采用ＣＹＢＥＸＩ＋等速测力系统及ＫＩＳＴＬＥＲ三维测力系统分别对运动员的膝、踝、肩、肘关节肌力和下肢爆发力进行冬训前后的测试，结果表明：冬训后，运动员膝伸肌、肩内旋肌、肘屈肌群的爆发力有很大提高；肘伸肌爆发力快速时有增长；踝关节屈伸肌力虽有增长，但不显著。手球专项运动员关节肌力特点：膝、踝、肘关节肌群峰力矩值和总功随运动速度的加快而下降，肩关节肌群峰力矩值和总功随运动速度的加快变化不大；膝、肩、肘关节肌群的平均功率和加速能随运动速度的加快而增大，踝关节肌群的平均功率和加速能随运动速度的加快在快速时呈下降趋势  相似文献   

金融企业职工人体成分分析及与血压关系研究     

李秋桂  姬芳勤  程合理 《科教文汇》2014,(36):111-112

目的：了解和评价金融企业职工的身体状况,指导对自身健康进行有效的管理。方法：选择某金融企业体检者497名,排除严重心脑肝肾疾病,肿瘤患者,急性炎症患者及长期服药者等。通过Biospace InBody 220人体成分分析仪对身体水分含量、蛋白质、无机盐、体脂肪、骨骼肌含量、体质指数、体脂百分比、腰臀脂比等指标进行测定。同时测定血压。所有指标的测定均由我院医护人员经过统一培训后进行操作。结果：除体脂肪外,身体水分、蛋白质、无机盐、骨骼肌肉量、体质指数、体脂百分比、腰臀脂比均受性别的影响（p＜0.05）。除身体水分外,人体成分中蛋白质、无机盐、体脂肪、骨骼肌肉量、体质指数、体脂百分比及腰臀脂比均与收缩压、舒张压水平密切相关（p＜0.001）。结论：金融企业职工倾向于体脂肪超标,人体成分与血压水平密切相关。通过对人体成分的分析,可早期发现人体成分的异常变化,指导改变不良的生活方式和行为,对自身健康进行有效的管理,预防相关疾病的发生。  相似文献

Is firm-specific innovation associated with greater value appropriation? The roles of environmental dynamism and technological diversity     

Heli Wang  Wei-Ru Chen 《Research Policy》2010,39(1):141-154

This paper extends the resource-based theory of the firm to examine the contingencies that either intensify or reduce the relationship between firm-specific innovation and value appropriation. Based on a large-scale analysis of a sample of US manufacturing firms, we found that greater innovation rents appropriation is associated with an increase in firm specificity of its innovative knowledge. But the positive relationship between firm-specific innovations and firm value appropriation tends to decrease when the product or technology market is highly dynamic. Further, under high environmental dynamism, firms should increase the diversity in their knowledge composition in order to mitigate the risk of value erosion associated with firm-specific innovations.  相似文献   

Meaningful learning with mobile devices: pre-service class teachers’ experiences of mobile learning in the outdoors     

Tomi Kärki  Heli Keinänen  Anu Tuominen  Marianna Hoikkala  Eila Matikainen  Hanna Maijala 《Technology, Pedagogy and Education》2018,27(2):251-263

The authors consider the use of mobile learning environment ActionTrack in teacher education. Pre-service class teachers’ (N = 277) experiences of the mobile learning environment were measured with a 7-point Likert-scale questionnaire based on seven attributes of meaningful learning. Students’ ratings for different attributes were analysed quantitatively. The authors conclude that, based on this analysis, it is possible to create meaningful learning experiences using ActionTrack. All the measured attributes of meaningful learning obtained positive values. In the mobile learning events of this study, three attributes arose as the essential features: mobile learning in the outdoors was primarily considered collaborative, active and contextual.  相似文献   

Creative and playful learning on technology-enriched playgrounds: an international investigation     

Justus J. Randolph  Marjaana Kangas  Heli Ruokamo  Pirkko Hyvönen 《Interactive Learning Environments》2016,24(3):409-422

The purpose of this quasi-experimental study was to determine the degree that creative and playful learning (CPL) in a technology-enriched playground influences academic achievement of students and what factors are responsible for successes. The participants were 276 students from 12 elementary classrooms in the Netherlands and Finland. The research used a pretest–posttest, without control design. The dependent variable was academic achievement on teacher-created tests; the independent variable was participation in the intervention; and the control variables were pretest scores, gender, academic subjects previously studied, age, satisfaction with schooling, country of the school, and classroom within the school. The results showed that there were significant gains in academic achievement and that the pretest was the only significant predictor of posttest achievement. Other variables, including gender, academic subjects studied, age, satisfaction with schooling, country of school, and classroom, were not statistically significant predictors of posttest scores. While students’ academic achievements are only one measure of progress in the current debate about learning in the education system, this article provides insight on education through analyses of the relationships among the integration of curriculum-based learning, CPL practices, and outdoor playgrounds.  相似文献

男子400m个人混合泳分段速度变化特征及主成分分析     

张和莉 《成都体育学院学报》2011,37(3)

对男子400m个人混合泳运动员各分段成绩研究发现:第1段游速最快,第6段游速最慢,第4段出现途中游加速即1加现象,这是运动员在第1段快速加速后身体适应性调整的必然结果。主成分提供的第23、段、第4段和第8段信息是全程速度变化研究的重点,第8段冲刺能力受前7段制约,因此,体能研究重点更多是对第23、段和第4段分配合理性的分析,第1段的游速对全程体能分配具有至关重要的作用。  相似文献   

基于线性规划的回归支撑向量机   总被引：1，自引：1，他引：0  

谢宏魏江平  刘鹤立 《上海海事大学学报》2006,27(1):49-52

在结构风险中采用l∞-范数来控制模型复杂性的基础上,提出基于线性规划的支撑向量机,并通过求解对偶规划来提高单纯形学习算法的计算速度.数值试验结果表明,此类支撑向量机的学习效果与经典的支撑向量机的学习效果相似,当学习样本个数增加时线性规划支持向量机的学习时间增加的要少得多,但是支撑向量个数比较多.  相似文献
