需求响应对提高仰卧起坐成绩的研究

Research on Demand Response to Improve the Performance of Sit-ups

目前,仰卧起坐作为全国各省市体育中考选考项目之一,也是女生选考项目中最易得分的考核内容之一。在做仰卧起坐时,主要是腰部和腹部发力,是腹肌参与一个力量耐力型项目。以深圳市体育中考为例,仰卧起坐选考项目为15分,大部分初三女学生对仰卧起坐的需求响应非常大,但目前很多初三女学生对于该项目成绩难以实现更大突破,还有部分肥胖考生根本完成不了1个标准仰卧起坐。因此,本文基于初中女生对仰卧起坐的需求,通过文献资料法、实地考察法和教学实践等方法,针对提高仰卧起坐成绩过程中出现的常见错误、产生原因和纠正手段进行研究,以期能够为体育教学工作者提供一定的理论支撑,使其通过最有效的教学手段进行干预提高。

At present,sit-ups are one of the sports examination items in all provinces and municipalities in China,and also one of the easiest scoring items for girls.When doing sit-ups,the main force is the waist and abdomen;the abdominal muscles participate in a strength endurance project.Taking the Shenzhen Physical Education Secondary Examination as an example,the sit-ups are 15 points.Most of the female students in the third grade of junior middle school respond very much to the need for sit-ups.However,at present,many female students in the third grade of junior middle school are difficult to achieve greater breakthroughs in this project,and some obese candidates can not complete a standard sit-ups at all.Therefore,based on the demand of girls in junior middle school for sit-ups,this paper studies the common mistakes,causes and corrective measures in the process of improving sit-ups through the methods of documentation,field investigation and teaching practice,so as to provide some theoretical support for physical education teaching workers and make them intervene and improve through the most effective teaching methods.
