Grip strength increased with age, and the mean grip strength is lower than the national average level of the same age, there was a significant difference between boys and girls in each age grip(P <0.01); zuoweiti proneness change with the age growth, the age between body antexion was higher than the national average level of the same age, 7, 8 12 years old, male and female students sit and reach significant difference(P <0.05); standing long jump with age increased, 8 year old men and women live in a very significant difference(P <0.01); 50 meters with the increase of age changes, boys 50 meter race with age decreased 8, 11, 9, and 12 year old men and women live in a very significant difference(P <0.01), 10 year old men and women live in significant difference(P <0.05); skipping changes with age, 7, 12 year old men and women live in very Significant differences(P <0.01), the 8 year old male and female students have significant difference(P <0.05); one minute sit up with the increase of age and different, 7, 11 year old male and female students have very significant difference(P <0.01), 8 years of age between male and female students have significant difference(P <0.05); 50 * 8 round-trip run changes with the increase of age, there was significant difference between the 9, 10, 11, 12(P <0.01) between male and female students aged 7-12 in rural areas; Bai students’ overweight and obesity in Zhangjiajie city the proportion is not high, but the low weight ratio of outstanding, low birth weight is the highest proportion of a year(39%) the first grade boys and girls(36.6%), the proportion of male and female students with overweight and obesity is increasing with the increase of the grade; visual Bai students in rural normal ratio 58.3%, mild 29.2%, moderate poor eyesight of poor eyesight was 8.3%, severe vision 4.2%, but with increasing age poor eyesight detection rate at elevated; rural Bai students Ascaris infection situation is more serious, male Ascaris infection rate accounted for 55.4%, girls accounted for 45.2%; rural Bai students flatfoot detection, detection of mild flat rate is higher, the male students left, right foot mild flatfoot detection rate accounted for 67% and 78% respectively, girls accounted for 69.4%, 80%, detection of flatfoot in boys higher than girls(P < 0.05). Zhangjiajie City, the level of physical development of 7-12 years old in rural area of Bai nationality students overall behind the national average, the quality of the parts of the body is higher than the average level of the same age, but upper body strength and endurance level is poor, the health situation is concerns.In order to learn about the situation of the Bai nationality students’ physical.and health that are from the countryside of Zhangjiajie city.the students’ age is from 7 to 12.At the same time.we can provide the gist of reference so that it can improve students’ healthy level of the national minority in Zhangjiajie city.I Extracted 473 students of the Bai nationality that they are 7 to 12 by random.they are from the countryside of Zhangjiajie city. I used many ways that I tested their physical,height,weight,the chest,the pulse,blood pressure, lung’s capacity and grip, standing long jump,zuo wei Ti Proneness,jump rope for one minute,sit-ups for one minute,running for so meters,twice run back and forth for somx8,sight,flat feet the infection of roundworm.At the same time,I have analyzed the mathematical statistics.Result:(1) The Bai nationality students are from Zhangjiajie.their age is from 7 to 12.Their age influences their height,weight,the chest and the thickness of crease.They have arresting differences between the 8-year-old boy and the 8-year-old girl.(p<0.01);They also have arresting differences between the boys and girls of 7,8,9,10,11 and 7,11,12.The arresting differences are the thickness of upper arm crease and the thickness of the abdomen crease.(p<0.01);The Bai nationality students change their pulse and blood pressure according to their age. The lung’s capacity caw increase according to their age.They have arresting differences about lung’s capacity between boys and girls of 8,9(p<0.05). There are arresting differences about the pulse between boys and girls of 11,12.(p<0.05);Their physical qualities have some different changes according to their age. The grip increases according to age.But the level is lower than the other children in china. There are many differences between boys and girls according to different ages.The Bai nationality students’ ratio of overweight and obesity is not high.But the ratio of low weight is very arresting;Conclusion:The Bai national students are 7 to 12.They are from ZJJ city.Their growth is lower than the average level of china.But a few are higher than the average level in china.Their upper body strength and endurance level are poor.I do worry about their health.Suggestion:We must promote the country side economy development of zhangjiajie.We should carry out the guiding ideology “health first”.We also should strengthen training of endurance quality.We must improve the nutritional status of the Bai nationality students.Thus we can improve the physical health level of students. |
