Zhejiang Province From 1985 To 2000 Students To The Laws Of Physical Development And Dynamic Studies

Superior material life is based on economic development, which , however, at the same time has negative influences on human beings. "Health problem" is one of them. How can human beings not only enjoy abundant material life but also have sound body and mind? It has been proved in practice and research in all countries of the world that it is effective to prevent "health problem" by improving people's physical constitution. Therefore, it has been a top priority for all countries to pay close attention to children's health by examining the characteristics of children's physical and mental development and finding ways to improve children's physical constitution, which is also a hot point in physique research. Zhejiang is one of the provinces whose economy develops most rapidly since 1978 when China started to put into effect the policies of reform and opening to the outside world. During this period, only a little can be found of research on children's physical constitution in the Province. On this practical basis and with experiences learned from the literature at home and abroad, a study was done in this paper on students' physical constitution of Zhejiang province through mathematical statistics, questionnaire and visit.A comparative analysis was made in the study on the constitution of students aging from 7 to 22 between 1985 and 2000 in Zhejiang province in morphological indexes (height and weight), functional index (vital capacity) and athletic performance indexes ( 50-meter sprint, standing long jump, toe-touch, slope pull-up for students of 7-12, shuttle run, pull-up for students of 13-22, 1000-meter running for boy students, 800-meter runningfor girl students and sit-up for girl students). All the students were divided into four groups: they were urban boy students, rural boy students, urban girl students and rural girl students. The characteristics of dynamic changes of physical constitution within the four groups in a period of 15 years were found as follows: during "the rapid growth period" all the girl students are advanced in morphological and functional indexes and the boy students remain unchanged in morphological indexes but advanced in functional index; during "the growth slow-down period" the boy students remain unchanged in vital capacity, the whole slow-down length is prolonged for the rural girl students in height, weight and vital capacity, all the rest indexes show the tendency of shortening in the slow-down length ; at "the first growth-stop age" and "the growth peak age" all the groups are tending to advance in all the indexes except that the index of weight of the rural girl students and the index of vital capacity of urban girl students are postponed and each group has its own characteristics in the indexes of athletic performance, other findings are that since 1985 students of Zhejiang province are slowing down in the average growth rate in morphological development, the vital capacity is getting smaller and smaller and some indexes of athletic performance show a declining tendency. In the light of the above findings the author put forward some constructive suggestions.
