| Physical fitness is not only the basis of human ability to work and activities,but also an important component of national quality.College students are the main force to realize China's dream of rejuvenation.Their physical health level is closely related to the future of the country,especially to the development of the nation.With the acceleration of social transformation,fierce academic competition,huge employment and psychological pressure,as well as unhealthy lifestyle,make the health status of this group worrying.In recent years,students' physical health has always been the focus of national and social attention."if the youth is strong,then China is strong",the students' physical development in the future is a great event related to the future of the country and the nation.This paper,based on the four-year undergraduate study of Nanchang Aviation University in 2014-2017,uses the methods of literature,experiment,contrast analysis and mathematical statistics to track and investigate the physical health of the 2014 undergraduates of Nanchang University of Aviation.The results show that:Compared with 2014,the BMI index of boys in 2015 and 2016 did not change significantly(P>0.05),and the BMI index in 2017 was significantly higher and the difference was very significant(P <0.01);the BMI index of girls in 2015 did not change significantly,and in 2016 and 201 It decreased significantly after 7 years(P<0.01).In 2015,2016 and 2017,the vital capacity of male and female students increased significantly(P < 0.01),and decreased significantly in 2017(P < 0.01),while the vital capacity of male and female students increased significantly in 2015,2016 and 2017(P<0.01).The average running time of 50 m in male and female was significantly decreased in 2015 and 2016(P < 0.01),but there was no significant change in 2017(P>0.05).Boys' standing long jump scores in 2015 and 2016 were significantly lower than those in 2014(P<0.01),and their standing long jump scores in 2017 were significantly lower than those in 2014(P< 0.01).The standing long jump scores of girls in 2016 and 2017 were significantly higher than those in 2014(P<0.05),but there was no significant change in 2015(P>0.05).The scores of male and female students in seat and body flexion from 2015 to 2017 were significantly higher than those in 2014(P<0.01).There was a significant change in boys' results of1000 m running in 2015 and 2017,with an increase in 1000 m running in 2015 and a decline in 1000 m running in 2017(P<0.01),and there was a significant difference between 2015 and 2 in girls(P<0.01).The 800-meter run in 016 rose and fell in 2017.There was a significant difference between 2015 and 2017(P<0.01).In 2015-2017,the scores of male students were significantly higher than those of 2014(P<0.01).Compared with 2015,the scores of male students in 2016 and one-minute sit-up in girls were significantly higher than those in 2014(P < 0.01).There was no significant change in the BMI index of girls(P>0 05),the BMI index of boys in 2017 was significantly higher than that of girls(P<0 01),and the BMI index of girls in2017 was significantly decreased(P<0 01).The vital capacity of boys in 2016 and2017 was lower than 20%.15 years(P<0.05),the vital capacity of female students in2016 was higher than that in 2015(P<0.05),and the vital capacity of female students in 2017 was significantly lower than that in 2015(P<0.01),and the 50 M running time of male and female students in 2016 was significantly shorter than that in 2015(P<0.01).In 2017,the running time of 50 m in male and female was significantly longer than that in 2015(P<0.01).There was no significant change in standing long jump between male and female in 2016(P>0.05),male in 2017,male in 2017.Girls' standing long jump scores were significantly higher than those in 2015(P<0.01).20 In 16 years and 2017,the results of male and female students were significantly higher than those of 2015(P<0.01).In 2016,there was no significant change in boys' results of 1000 m running(P>0.05),and the results of 800 m running of girls were significantly better than that of 2015(P<0.01).In 2017,the scores of male and female middle and long distance runners were significantly lower than those of 2015(P<0.01).In 2016,there was no significant change in male students' pull-up(P>0.05),and the one-minute sit-up scores of female students increased significantly(P<0.01).In 2017,boys and girls sit up and sit up for one minute.Compared with 2016,the BMI index of male students increased significantly in2017,while the BMI of female students had no significant change(P>0.05.The vital capacity of male and female students in 2017 and the 50 m running score of male and female students were significantly higher than that of 2016(P<0.01),and that of male and female students was significantly higher than that of 2016.The results of standing long jump in male and female students in 2017 were significantly higher than those in 2016(P<0.01),and the results of sitting and body flexion in 2017 were significantly lower than those in 2016(P<0.01),and that of male students in 2017 was significantly lower than that in 2016(P<0.01).Female students' performance in forward flexion in sitting position was higher than that in 2017.,but the change was not obvious(P>0.05).The results of the experiment are as follows:The overall physical health level of undergraduate students in Nanchang University of Aeronautics is general,the overall score is only in the pass level,and the grade distribution is mainly concentrated in the passing standard.The physical health performance of the undergraduate students of Grade 2014 shows the development trend of rising first and then decreasing during the period of school.In the sophomore and third-year period,the development was good,and there was a marked decline in the fourth-year period.The undergraduate students of Nanchang University of Aeronautics have a good level of body shape and quality,and their scores are in excellent level,and the distribution of grades is mainly concentrated in the normal standard.The height of both male and female undergraduates increased significantly,the weight of boys increased significantly,and the weight of girls tended to decrease.1)The overall physical function level of undergraduates in Nanchang University of Aeronautics is general,the score is in the pass level,the grade distribution is mainly concentrated in the passing standard,and the level of vital capacity is lower.The overall physical function of the students decreased significantly during the period of college,mainly in the fourth year of the decline,the overall level of vital capacity development is not good.2)The overall physical fitness level of the undergraduates in Nanchang University of Aviation is generally,the scores are mostly in the passing level,the power quality is the worst,and the quality of the male power has been at the level of failure.During the school,there is no obvious change in the speed quality,the explosive force,the flexibility,the strength and the quality of the whole are on the rise,and the overall endurance quality is in a downward trend.3)The overall physique of grade 2014 undergraduate students in Nanchang University of Aeronautics was the best in 2015 / sophomore period,and the overall physique of female students was better than that of male students.In view of the development of undergraduate physical health in Nanchang Hangkong University,the following countermeasures are put forward: strengthening the construction of teaching staff,strengthening the construction of school physical education thought,and establishing the physical education thought belonging toNanchang Aeronautical University;To strengthen the construction of campus sports culture,to create a good sports atmosphere,to strengthen the construction of campus basic sports facilities,to meet the needs of students for sports venues,to strengthen the construction of extracurricular physical exercise system,to form a good physical exercise habit. |
