2005年济南市槐荫区部分儿童少年皮脂厚度与运动素质调查

Investigation on Sebum Thickness and Sport Quality among Children and Teenagers in Huaiyin District,Ji'nan,2005

[目的]了解儿童少年的皮脂厚度,评价其与运动素质的关系。[方法]2005年10月,在济南市槐荫区抽取部分城乡中小学生进行调查。[结果]调查城区男生309人,乡村男生394人,城区女生297人,乡村女生285人。女生皮脂厚度随年龄的增长而不断增长;男生青春期前随年龄的增长而增长,青春期后缓慢下降;皮脂厚度17岁女生城乡之间的差异无统计学意义(P>0.05),其他各年龄组男女生的均为城区大于乡村,差异有统计学意义(P<0.01)。男女各年龄组皮脂厚度与速度、耐力、爆发力、柔韧性均呈不同程度的负相关关系,多数相关有显著性(P<0.05或<0.01)。[结论]儿童少年皮脂厚度与运动素质关系密切,皮脂厚度增加对身体素质发展不利。

To understand the sebum thickness of the children and teenagers, evaluate its relationship with sport quality. [Methods]investigation was conducted among some primary and middle school students from urban and rural areas in Huaiyin District in October,2005. [Results]309 and 394 boy students from urban district and rural areas, 297 and 285 girl students from urban district and rural areas were investigated. Girl students＂ sebum thickness increased along with the increase of the age. The boy students＂ sebum thickness increased along with the increase of the age during adolescence and decreased slowly after adolescence. There was no difference of sebum thickness in girl students aged 17 from urban and rural areas （ P 〈0.05）. The sebum thickness of boys and girls in other aged groups from urban areas is thicker than that from rural areas. There was a difference （ P 〈0.01）. There was a negative correlation of the sebum thickness of boys and girls in all aged groups to the speed, endurance, sudden power and flexibility levels to some extents. And most rela- tions were significant （ P 〈0.05 or〈0.01）. [Conclusion]The sebum thickness of children and teenagers was closely related with their sport quality and the increase of sebum thickness will do harm to the development of their physical quality.
