研究表明,儿童少年时期所受的各方面影响与其成年后的健康状况密切相关,因此,认识儿童少年生长发育规律和理论具有十分重要的现实意义及战略价值。本文应用文献资料法、实验测定法和统计学方法,对晋城市7-18岁中小学生身体形态、机能和素质三类十一项指标进行了动态分析。结果显示,近15年晋城市7—18岁中小学生身体形态方面均有不同程度增长,素质指标中速度素质的发展在15年内基本上保持稳定,略有下降。其余各项素质之中,男生除力量素质有一定程度提高外,耐力素质和柔韧素质则表现出明显的负增长趋势;而女生的各项素质指标都有不同程度的下降。此外,男女学生身体机能的现状不容乐观,肺活量和肺活量/体重在15年内整体呈现下降趋势。

Therefore, it is of great practical significance and strategic value to recognize the law and theory of adolescent growth and development. In this paper, using literature, experimental determination and statistical methods, dynamic analysis of eleven indicators of body shape, function and quality of primary and secondary school students aged 7-18 in Jincheng City was carried out. The results show that the body shape of primary and secondary school students aged 7-18 years in Jincheng City have all increased to some extent in recent 15 years. The development of speed quality in quality indicators remained basically stable and declined slightly in 15 years. Among all the other qualities, the male students showed a significant negative growth trend in strength except their strength and quality. However, all the quality indicators of the girls decreased in varying degrees. In addition, the status quo of male and female students’ body function is not optimistic. The vital capacity and vital capacity / body weight overall show a downward trend in 15 years.
