Research On The Impact Of Shared Bicycles On The Physical Fitness Of College Students Under The Background Of National Fitness

According to the comparison and analysis of the data of national physique monitoring report,it is found that the physical quality of college students in China is in the decline stage,and the physical qualities include several factors: strength,speed,endurance,flexibility,coordination and so on,while sharing a single car as a new type of environmental protection traffic equipment is welcomed by college students.By understanding the physical health of the college students now,this paper searches the relevant literature of the national physique monitoring report by literature,sums up the changes in the physical quality of the college students in China,and uses the questionnaire survey method to send out questionnaires to the college students in Chengdu,and collects the views of the students on the impact of the shared bicycle on the physical quality;the mathematical statistics method collects the questionnaire after the survey.This paper analyzes the specific changes and the proportion of several factors that affect the physical quality of shared bicycles.According to the four factors of coordination,strength,endurance and sensitivity before arranging,we design experiments.From the four elements of coordination,strength,endurance and sensitivity in the physical quality,the college students who have no obvious differences in the basic information such as age,height,weight and physical quality(P>0.05),forty and 20 are divided into experimental and control groups for 10 weeks.During this period,different experimental requirements are set for the two groups of college students,respectively.Including the use of the time of sharing a single car.Before the experiment,the two groups were tested before the experiment,and the results were tested by independent sample T.Before the experiment,the physical quality data of the two groups of college students were compared to ensure that the physical qualities of the two groups of the students in the experimental group and the control group were not statistically different before the experiment,and at the same level.After the experiment,the test data of the control group did not change obviously,and the experimental group was tested after the experiment.The results showed that the difference between the cross jump,the 30-meter run,the closed head crane,the wall squat,the Bobbi jump and the hand reaction was statistically significant(P<0.05).The results showed that the students in the experimental group were in the ability of coordination,leg strength,and agility,respectively,three after using the shared bicycle.There are changes in factors,including cross jumping,closing eyes,standing up,sticking to wall,squat,Bobbi jump and hand reaction.It shows that shared bicycle has the following characteristics: "improving coordination ability","improving leg strength" and "improving sensitivity" for college students’ physical quality.In addition,there was no significant difference in the depth of squatting and lung activity before and after the experimental group(P>0.05),indicating that the students’ use of shared bicycles may have no explicit effect on endurance,but the stamina data did not mean that the shared bicycle had no effect on the physical quality.It may be in the experiment that the subjects used the time length and the number of times to share the bicycle.Sufficient or shared bicycle’s influence on endurance factors in physical fitness can not lead to obvious difference in the experimental data.
