A Comparative Study Of The Youth Physical Health Of Students In Southern, Northern And Middle Jiangsu

Research purposes:this study combined with jiangsu province primary and middle school students physical health baseline, southern jiangsu and northern jiangsu of jiangsu province in2011are compared with those of the middle717-year-old young students body shape, body function, the healthy development of the sports quality status, and discusses the dynamic changes of the youth physical health of students in jiangsu province trend and regional differences in characteristics. Leading to local government, society, schools and families focus on adolescent students’ body development, strengthen the education of physical education and health care, in order to further improve and balance the child and adolescent students physique and health condition in our province to provide scientific basis.Research results:1. The body shape aspects:compared with the baseline in2010, the average height of students in the south of jiangsu, northern jiangsu and middle students decline phenomenon. Southern jiangsu, northern jiangsu and middle height:compared to the same gender students to junior middle school stage (12-14) jiangsu subei is obviously better than the height growth of students (p<0.01); Elementary school, high school (7-11,15-17) jiangsu height confrontation is obviously better than the development of students (p<0.01); Subei students as a whole is better than that of middle students (p<0.05);Compared with the baseline in2010, the southern jiangsu and northern jiangsu student body weight are middle students is lower than the2010baseline. Southern jiangsu, northern jiangsu and middle:compared to the same gender students to weight the subei students overall higher than students in the south of jiangsu, boys weight mean difference0.3, female0.2; Sunan students overall superior to middle students, the male weight mean difference0.5, female0.4;(10-12) subei weight significantly higher than the middle students (p<0.01);Baseline with2010, north jiangsu student chest rise is bigger, sunan students chest development situation is more stable, while the middle students to bust a downward trend. Southern jiangsu, northern jiangsu and the confrontation with the bust (11-12) compared to the same gender students subei students is bigger than the bust sunan chest (p<0.01);(11,14,12years old) students in the south of jiangsu is bigger than the bust middle students chest (p<0.01);(7-11,15-17) subei students is bigger than the bust middle chest circumference (p<0.01).2. The body function. Southern jiangsu, northern jiangsu and middle students form index level as a whole, the index of lung capacity to keep the consistency of development. Basic on vital capacity mean in middle> south of the north jiangsu. Compared with baseline year of2010, the southern jiangsu and middle lung capacity have male and female students is greatly improved, subei male, the female students significantly decline. Southern jiangsu, northern jiangsu and the confrontation with gender vital capacity (7-17) compared to the vital capacity in the south of jiangsu is significantly higher than subei vital capacity (p<0.01), boys average lung capacity by304,258.7; Middle subei vital capacity, vital capacity as a whole is higher than the difference is not obvious; Vital capacity (7-17) middle students is significantly higher than subei vital capacity (p<0.01), boys average lung capacity difference of319.7,217.4girls.As2010baseline, southern jiangsu and northern jiangsu boy mean grip strength index declined, the confrontation male students increased; Girls, on average, grip strength index development situation is more stable, increased from2010, the middle female students increase the largest. Southern jiangsu, northern jiangsu and the confrontation with gender students grip strength index, compared to the middle students to maximum grip strength index, subei students to a minimum.3. The movement quality. Compared with baseline,2010, the southern jiangsu and middle speed quality of male and female students has increased, and subei students speed quality slightly down compared with2010. Southern jiangsu, northern jiangsu gender students ran50meters with the confrontation:compared to the south of jiangsu and middle difference, were significantly better than students in north jiangsu,11-15age group has significant difference on statistical significance (p<0.01);Southern jiangsu and northern jiangsu student power quality was increased from2010, and China compared with2010for men and women students decline phenomenon. Students in the south of jiangsu and north jiangsu, middle students gap mainly appears in the stage of primary school (7-12years of age), the gap is more obvious, has obvious differences in statistical significance (p<0.01); Subei mainly appeared in the high school students and middle gap (12-17years of age), has obvious differences in statistical significance (p<0.01);Endurance quality aspect, southern jiangsu and northern jiangsu and middle students has increased from2010, the biggest students improve in the areas of southern jiangsu, northern jiangsu area students improve amplitude is smaller. Significantly better than students in the areas of southern north jiangsu and middle students,13-15years old age gap is bigger, has obvious differences in statistical significance (p<0.01). Subei students with middle gap mainly embodies in the junior middle school stage (12-14years of age), middle students’endurance quality is superior to the subei students (p<0.01).Research conclusions:4.1.1In2011, our province primary and middle school students’ body form development status from2010has further improvement, height, weight and chest circumference are generally higher than in2010. With the same age stage of the northern and middle students, compared to the height of students in the south of jiangsu development level is relatively good, significantly higher than that of north jiangsu and middle students, the northern and middle students difference; With the same age stage of male students compared to middle students, subei students the highest level, body weight, chest circumference development but at the same time, subei students obesity rate was the highest in three areas of performance;4.1.2In2011, our province primary and middle school students of various physiological functions in general from2010annual average have improved, primary school, middle school and high school male and female students, on average, vital capacity, vital capacity index weight are higher than level2010. With same age stage of the northern and southern jiangsu students compared to middle students1body development is relatively good, the development of the vital capacity index and subei students has obvious difference, slightly higher than southern jiangsu;4.1.3Holdings compared with2010,2011, our province students’physical quality further improve overall, most ages, the speed of the upper body strength, endurance, explosive force of lower limb, flexibility and other quality indicators are improved. With the same age stage of the northern and middle students, compared to southern jiangsu students speed quality, strength, quality, endurance quality are the highest in the three regions with gender students. Including middle students speed quality, endurance quality better than that of north jiangsu, northern jiangsu power quality better than middle students.
