摘要
研究依据:根据大量的相关媒体报道,人们在社会经济和生活水平提高的背后影藏着的却是儿童素质的下降。回顾我国中小学校园体育的种种问题,尤其是在教学观念,教学方法,教学内容都已经满足不了现在学校体育的教学要求。其次由于青少年生长发育关键期的存在,此阶段身体系统的运动机能和运动能力发展的提高都非常敏感,所以在学校体育教学当中应该引起我们的高度重视,特别是在小学体育教学阶段。面对我国青少年体质所面临的瓶颈和我国田径在学校体育的开展之状,如何把青少年的体质健康与田径运动、田径与校园体育衔接起来显得至关重要。世界上最恐怖的电影
研究意义:本文着重从“少儿趣味田径”教学项目对(10-12)岁小学生身体机能各指标相互影响关系入手,最主要是通过与传统田径教学项目下的各项指标进行对比分析,分析讨论“少儿趣味田径”对小学生身体机能系统中各机能之间影响的特点和规律,为进一步推广“少儿趣味田径”和改善田径在小学体育中的开展现状、提高小学生的身体机能以及小学体育课程改革,特别是教学观念和教学方法的改进,为今后“少儿趣味田径”的引进和有效开展提供理论支撑和实践保障。
研究对象及方法:本实验随意选取陕西师范大学大兴新区实验小学五年级两个自然班共96名学生,通过实验前各项指标的测试,剔除数据差异过大的学生。本文着重采用实验法进行为期一学期的教学实践,然后采集数据分析实验前后小学五年级男、女生的循环机能、呼吸机能、感觉与神经机能、平衡机能等各个指标的变化情况。
研究结果:(1)实验前后实验组、对照组循环机能的变化,对照组男、女生的安静心率、运动后即刻心率、恢复到安静心率的时间、收缩压、舒张压、运动后即刻收缩压、运动后即刻舒张压(P>0.05)无显著性差异,台阶指数实验前后(P<0.05)有显著性差异;实验组男生的运动后即刻心率、恢复到安静心率的时间、台阶指数实验前后(P<0.01)有非常显著性差异;安静心率、收缩压、舒张压、运动后即刻收缩压、运动后即刻舒张压实验前后(P>0.05)无显著性差异,女生运动后即刻心率(P<0.05)说明实验前后有显著性差异,恢复到安静心率的时间、台阶实验指数(P<0.01)实验前后有非常显著性差异。
(2)实验前后实验组、对照组呼吸机能的变化,对照男、女生的肺活量、时间肺活量和最大通气量实验前后(p>0.05)无显著性差异;实验组男生的肺活量、时间肺活量实验前后(P<0.05)有显著性差异,最大通气量实验前后(P>0.05)无显著性差异,女生的肺活量实验前后(P<0.05)有显著性差异,时间肺活量实验前后(P<0.01)有非常显著性差异,最大通气量实验前后(P>0.05)无显著性差异。
(3)实验前后实验组、对照组感觉与神经机能的变化,对照组男、女生的感知跳跃距离测试和简单反应时实验前后(p>0.05)无显著性差异,选择反应时实验前后(P<0.05)有显著性差异;实验组男生的感知跳跃距离测试实验前后(P<0.01)有非常显著性差异,选择反应时实验前后(P<0.05)有显著性差异,女生的感知跳跃距离测试实验前后(P<0.05)有显著性变化,选择反应时试实验前后(P<自动挡挂挡
挥泪斩马谡的故事0.01)有非常显著性差异。
(4)实验前后实验组、对照组平衡机能的差异,实验前后对照组男生闭眼单脚站立、
侧跨跳平衡实验(p>0.05)无显著性差异;实验组男生的闭眼单脚站立实验前后(P<0.01)有非常显著性差异,测跨跳平衡实验前后(P<0.05)有显著性差异,对照组与实验组女生的闭眼单脚站立实验前后(p>0.05)无显著性差异,测跨跳平衡实验前后(P<0.05)有显著性差异。
研究结论:(1)“少儿趣味田径”教学对(10-12)岁少儿身体的大多数循环机能无显著性影响,但对部分身体机的循环机能有明显的改善作用,主要表现在运动后即刻心率、运动后恢复到安静心率时间、台阶指数等相关指标效果明显。
(2)“少儿趣味田径”教学能提高(10-12)岁少儿的部分呼吸机能,具体表现在肺活量、时间肺活量指标上有显著的效果,且较之常规体育课具有一定的优势。
(3)“少儿趣味田径”运动可以有效发展(10-12)岁少儿的感觉能力,使其形成正确的用力感觉,对最大限度的发挥少儿知觉选择性和肌肉与神经的高度协调大有裨益。
(4)通过“少儿趣味田径”运动可以有效提高(10-12)岁少儿的身体平衡能力,改善少儿腿部力量的有效用力顺序。网络惊魂

教学感悟Rearch basis: In the last year, the decline in physical fitness and the weakening of athletic ability of children and adolescents in the world have called for the reform of track and field sports. In the same time, my country to reform the school’sport, the time and content of track and field cours have undergone major changes. They are nsitive periods for the development of various physical qualities. Faced with the bottleneck faced by our country's adolescents' physique and in development of my country track and field in school sports, how to link the physical health of young people with track and field sports. Athletics and school sports are crucial.
Significance of rearch: This study comprehensively studied the impact of the Children's Interesting Track and Field Teaching Program on the physical functions of (10-12)-year-old primary school students, and compared and analyzed the indicators under the traditional track and field teaching program to explore children's interest in track and field. The characteristics and laws of the influence of primary school students on the physical mechanism provide reference for the further promotion of
children’s interest in track and field and improvement of track and field development in primary school sports, improvement of primary school students’ physical functions, and to reforming primary education cours in elementary school, especially for track and especial on athletics cours .
Rearch facilities and methods: on the experiment, 96 students from five natural class in the fifth grade of experimental primary school of Daxing New District, randomly lected by Shanxi Normal University. Through the test of various indicators before the experiment, students with excessive data discrepancies were excluded. To is ud literature review methods, expert interview, experimental methods, statistical methods, and comparative analysis methods, through testing, and then analyze the size of the body (height, weight, BIM) and the function of the movement of boys and girls in primary and condary schools before and after the experiment. Respiratory to nsory and neurological function, balance function and other indicators of change.
