The Study About The Characteristics Of Physical Fitness Of 3 To 6 Years Old Children In Shanxi Province

Shanxi lies in the center of China, including 11 areas. The different economic conditions and life styles have great effects on the physical health of the infants. So it is very important to research physical fitness that is the composition of constitution of infants in the view that infants are the hope of the country.The development of physical fitness of infants in 3 to 6 years old have close relation with their height, weight, and physical health of body constitution. It is still rare at present about the research of sex difference and increasing degree and rate of increasing of body constitution in running, jumping, throwing, pliable and tough, coordination. So, it is very necessary to carry on the research.This Research uses the statistics of the indexes about height, weight, bust, sebaceous, quiet heart rate , seat crook in front of the body , standing long jump, tennis throw far, 10 turning back run , both feet jump and walk balance beam in the national physique monitoring to study the characteristics of the infants' physical fitness of 3~6 years old in Shanxi, the differences of physical fitness in urban and rural areas, increasing rate. This research makes spot check into 5504 infants (male infants 2789, female infants 2715) in 2005 national physical monitoring. The results are as follows:The pliability and toughness quality of Shanxi 3~6 -year- old female infants is better than those of male infants. In equilibrate ability, strength quality and sensitive quality;male infants are better than female infants. Both- feet- jump remains to be proved in further research. That 3~ 6-year-old male infants are better than female infants in every shape and function in Shanxi, it proves that in the age bracket heredity mainly determines quality of body constitution.In Shanxi province, it is from 3 to 5 that the physical fitness of 3~ 6-year-old children develops relatively rapidly. The increasing of strength, and balance level are obviously farther than other quality.The physical fitness of rural infants from 3 to 4 are better than that of urban infants, however, urban infants are better than rural infants from 5 to 6, especially in 6. It is illustrated that the heredity of the infants' physical fitness in 2001 is better than that in 2005,and perhaps postnatal environment of the infants in 2005 is better than that in 2001.In comparison of the physical fitness of infants in Shared, it is found that the cities with high economic conditions are relatively better such as the physical fitness in Taiyuan,Changzhi, and Yuncheng is obviously better than that in Lvliang. It is proved that the economic conditions and environment have great effects on the development of physical fitness.In comparison of the physical fitness of infants in year 2001 and 2005, the physical fitness in year 2001 of infants from 3 to 4 is better than that in year 2005, however, in year 2005 of infants from 5 to 6 is better than that in year 2001;it illustrates that the infants' physical fitness has been declining with improving of living conditions and declining of the outdoor activities. But the physical fitness of infants from 5 to 6 is obviously better than that in 2001 in the view that the infants' natural enjoyment of activities and enough nutrition in addition to the favorable facilities of game activities.
