Abstract: Based on the survey of physical development of students in 1985 and 1995 in China, initiated by state Education commission, State physical culture commission, Ministry of public health , State nationalities affairs commission and State science commission, based on the survey of physical development of students after the 30 's of the 20th century in several provinces and cities, the author conducted further statistics and obtained the results of acceleration of growth both in Chinese Han nationality students and Chinese minorities students, separately.
Through analyses of the results, the current condition of physical development both of them is mastered. Meanwhile the comparison between Chinese students and Japanese students also was dealt with. Firstly the stature and weight in 1995 were compared, and then the acceleration of growth was compared. The differences of physical development between Chinese students and Japanese students were revealed.
At present, the level of physical development of Chinese students is not very strong , but the values of acceleration of growth of Chinese students are larger than that of Japanese students. The value of acceleration of growth in stature is 2. 10cm ( male students) and 1. 65cm ( female students) larger than that of Japanese students. The value of acceleration of growth in weight is 2. 22kg ( male students) and 1. 54kg ( female students) larger than that o f Japanese students. The stature and weight present a larger secular increase trend, a kind of latent development. So there is a possibility of enhancement in physical development of Chinese students. Not quite the same with stature and weight, in China the value of acceleration of growth in chest girth in countryside students is rather lower than in the city students. It will make a notable impact on the physical quality and will retard the overall physical development of growth.
This situation w ill provide a reliable scientific foundation for making the policy and measurements. The economics in China now is being developed quickly. Some good actions have been made to improve the nutrition of students and to enhance the physical exercises. Therefore, the effects of promotion on physical development of Chinese students definitely will be confirmed in the future.
