近年来我国中学生体质状况一直不容乐观，北京市城区中学生的体质状况处于怎样的一个水平呢？作者采用问卷调查法、文献资料法、访谈法、数理统计法及逻辑分析等方法，以三帆中学中学生为研究对象，对三帆中学2005年和2008年初三学生体质健康测试结果进行比较，并对影响体质的若干因素进行研究分析。结果表明：目前北京市三帆中学中学生身体形态发育总体情况良好，但是超重肥胖现象严重；身体机能，呼吸机能和心血管机能下降；在身体素质方面，中学生下肢的爆发力减弱，上肢的力量有所增强。通过对三帆中学300名中学生随机问卷调查和教师访谈调查得出：缺乏良好的锻炼习惯、锻炼时间不能保证、运动强度和运动量不符合要求是影响中学生体质健康水平的主要因素。调查结果同时显示营养问题和家庭因素也是影响中学生体质健康水平的重要因素。论文针对以上情况和亟待解决的问题提出了若干建议。

In recent years, the physical health condition of students in secondary school is not optimistic. How about the situation in urban districts of Beijing? In this paper, the author mainly studies the health condition of students from San Fan Middle school. He adopts the methods of questionnaire survey, library study, interview, mathematical statistics and logical analysis to study the influencing factors to the physical condition. The author compare and contrast the health test result of 2005 and 2009, mainly of the students from junior three of San Fan Middle school. The result shows that the physical development of students in San Fan is in good condition on the whole. However, the explosion of obesity is serious now. What’s more the body functions such as breath strength and heart strength is decaying. From the aspect of physical strength, explosive strength of the lower extremities is reduced, while the power of upper extremities is developed. According to the random questionnaire survey among 300 students and interview with PE teachers, we come to the conclusion that there are three reasons for this change: absence of regular exercises, unsuitable exercise intensity and unsuitable exercises quality. Moreover, nourishment and family factors are also influencing factors to students’ health condition. At the end of this paper, the author also provides some suggestions which aim at the current situation.
