【摘要】：在儿童时期人体的柔韧素质发展最快。从人体生理学的角度上讲:儿童处于柔韧素质发展的敏感期,如果在这段时间内进行柔韧性练习会较大的促进柔韧素质的发展,提高儿童的体质健康水平。而且在儿童时期,由于心脏和肌肉发育的不完全,不应该在练习中加入过多的力量和耐力素质练习。在这一时期内进行较多的柔韧性练习是最为合适的。论文以中国石油大学附属小学二年级学生为例,随机抽取中国石油大学附属小学二年级4个班学生为实验对象,5班和6班为实验组,7班和8班为对照组。实验时间为16周。实验前先进行一次测试,实验后再进行一次总测试,测试的指标大部分采用国家小学生二年级体制健康测试指标(50米、侧向投沙包、400米跑、坐位体前屈、10米折返跑、10米榴莲球)。16周后,收集实验前后的测试数据,并对实验组和对照组二年级学生在实验前和实验后的各项身体素质指标(速度、力量、耐力、柔韧、灵敏、平衡)进行归纳、分析和总结,探索柔韧性练习对于7-8岁儿童身体素质发展的影响。研究结论主要有:1.柔韧性练习大幅度的促进了7-8岁儿童柔韧素质的发展。2.柔韧性练习对7-8岁儿童速度素质的发展有较大的促进作用。3.柔韧性练习促进了7-8岁儿童灵敏素质的发展。4.柔韧性练习可以促进7-8岁儿童平衡素质的发展。5.在实验组和对照组测试成绩增长幅度的配对样本T检验中发现两组学生力量、耐力素质的增长幅度没有显著性差异,柔韧性练习对7-8岁儿童的耐力素质和力量素质发展的作用并不突出,但是实验组耐力素质的增长幅度要大于对照组,表明柔韧性练习对于7-8岁儿童的耐力素质发展还是有一定的促进作用。
[Abstract]:The body's flexibility develops fastest in childhood. From the point of view of human physiology, children are in the sensitive period of flexibility development. If flexibility exercises are carried out during this period, it will promote the development of flexibility and improve the physical health of children. And in childhood, due to incomplete heart and muscle development, too much strength and endurance should not be added to the exercise. It is most appropriate to do more flexibility exercises during this period. Taking the sophomore students of the affiliated primary schools of China University of Petroleum as an example, this paper randomly selected 4 students from the second grade of the affiliated primary schools of China University of Petroleum University as the experimental objects, five and six classes as the experimental groups, and seven and eight classes as the control groups. The experimental time was 16 weeks. A test was conducted before the experiment, and then a general test was conducted after the experiment. Most of the indicators used in the test were the national primary school students' second grade system health test index (50m, lateral sandbag, 400m run, sitting position forward flexion, 10m reverse run). After 16 weeks, the test data were collected before and after the experiment, and the physical quality indexes (speed, strength, endurance, flexibility and agility) of the second graders in the experimental group and the control group were measured before and after the experiment. To explore the effects of flexibility exercises on the physical development of children aged 7-8. The main conclusions are as follows: 1. Flexibility exercises greatly promoted the development of flexibility of children aged 7-8. 2. Flexibility exercises have a greater role in promoting the development of speed quality of children aged 7-8 years. 3. Flexibility exercises promote the development of sensitive qualities in children aged 7-8. 4. Flexibility exercises can promote the development of balance quality of children aged 7-8. 5. There was no significant difference in strength and endurance quality between the two groups in the matched sample T test of the increasing range of test results in the experimental group and the control group. The effect of flexibility exercise on endurance quality and strength quality development of children aged 7-8 years was not prominent, but the increase of endurance quality in experimental group was larger than that in control group. The results indicate that flexibility exercises can promote the development of endurance quality of children aged 7-8 years.
