为探究现下高中学生在校期间体质健康水平发展不平衡的状况，运用文献综述法、问卷调查法、数理统计法将呼和浩特市铁路第一中学2019年参加国家体质健康测试的三个年级学生作为研究对象，对比分析三个年级学生的国家体质健康测试成绩，利用问卷的形式找出各年级学生体质发展不平衡的因素。结果表明：三个年级学生的身体形态，身高、体重并无显著差异(P > 0.05)；肺活量指数出现显著差异性(P < 0.05)；速度素质、耐力素质、力量素质出现了显著差异性(P < 0.05)。
In order to explore the current unbalanced development of high school students’ physical health during school, three grades of students from Hohhot Railway No. 1 Middle School who participated in the national physical health test in 2019 were analyzed by literature review, questionnaire survey and mathematical statistics. As the research object, the results of the national physical health test of the three grades were compared and analyzed, and the factors of unbalanced physical development of the students of each grade were found out by means of questionnaires. The results showed that there were no significant differences in body shape, height and weight among the three grades (P > 0.05); Significant differences in vital capacity index (P < 0.05); Significant differences in speed quality, endurance quality, and strength quality (P < 0.05).
