In order to understand the lines calisthenics 3-5 grade of schoolchild the effects of physical and psychological health, this paper, methods of documentation,experimental method, a questionnaire survey method, such as mathematical statistics, Dalang of Dongguan City shui lin school students in grades 3-5 research; 3-5 of schoolchild calisthenics training and physical fitness of students measured before and after training (height, weight, vital capacity, Sit and Reach, standing long jump, pulse) and psychological health; The results show that the contact schoolchild to promote the physical and psychological health, and social adaptability significant effect.

为了解健美操练习对小学3-5年级学生身心健康的影响，本文采用文献资料法、实验法、数理统计法等，对东莞市大朗水霖学校3-5年级学生进行了研究；对小学三到五年级学生进行健美操训练，并测定训练前后学生身体素质（身高、体重、肺活量、坐位体前屈、立定跳远、脉搏）和心理健康状况；结果表明，健美操练习对促进小学生身心健康以及社会适应能力方面有显著效果。

The correlation between the items of physical fitnees can be divided into two groups: pull-ups, flexed-arm-hanging, sit-up, standing long jump and soft-ball throw for distance are in one group, and 50 meter sprint, shuttle run and endurance run are in another group.

又体能测验各项目之间的相关，发现八项体能测验分成两组：第一组是引体向上、屈臂悬垂、仰卧起坐、立定跳远、和垒球掷远等五项；第二组是50公尺短跑、折返跑、和耐力跑等三项。

Methods The triceps and subscapular skinfolds were measured and the body composition were estimated by using Changling's and Brozek's models in a total of 376 twin pairs of Han nationality,including 245 monozygotic and 131 likesex dizygotic twin pairs aged 6 to 18 years.Modelfitting method with Mx package was performed to evaluate the proportion of variance components and to analyze the effect of sex,age and development period on the skinfold thickness and body composition.
