Since the occurrence of Corona Virus Disease 2019(COVID-19)(hereinafter referred to as “new coronary pneumonia”),the whole society of our country has responded actively.Phased victory.The new crown pneumonia epidemic has gradually made the public aware of the importance of health,and physical exercise has once again been brought back to the vision of people of all ethnic groups across the country as a convenient and cost-effective preventive method for the advancement of health barriers and the prevention and treatment of diseases.Under the new crown pneumonia epidemic,the value of sports is becoming more and more obvious.People of all ethnic groups have an increasingly strong desire to participate in sports,and the demand for physical fitness is even stronger.From the analysis of many cases,it is known that the elderly,the weak and the people with diseases have a higher proportion of severe illness or even death,while the young and middle-aged people,the better-physical and the better-formed groups,since they have contracted the new coronary pneumonia,But the recovery ratio and effect after treatment are better than the former.It can be seen that having a good physical fitness is the basis for overcoming all diseases.As an important reserve force for the realization of the great national rejuvenation,college students should receive greater attention for their physical health.According to the data in "The Development Process of Physical Fitness Monitoring of Chinese Students"(2017),the physical fitness of college students is still showing a downward trend,but the only thing that is fortunate is that the downward trend has slowed down.But at the same time,the body shape of Chinese college students is gradually changing,and the obesity indicator will increase by 2 to 3 percentage points every year.Therefore,how to solve the problem of declining students' physique and finding ways to improve their physique has become a top priority.Based on the above background,this research takes the physical health of students in higher vocational colleges in Hunan Province as the research object,adopts the research methods of literature data method,logical analysis method,questionnaire survey method,mathematical statistics method,and follows the research foundation,research hypothesis,mathematical derivation,Research results,research discussions,research strategies from theoretical research to empirical research,based on the structural equation model(SEM)to build a model of factors affecting students' physical fitness,and use mathematics to deduce the physical exercise attitude and physical exercise of students in higher vocational colleges in Hunan Province The relationship between motivation,physical exercise behavior and physical health,in order to clarify the influencing factors of the physical health of students in higher vocational colleges in Hunan Province,and propose corresponding countermeasures accordingly,in order to formulate and implement an integrated sunshine for all levels and types of schools The sports program provides a reference and a realistic basis for expanding new ways to improve the physical fitness of students.Research results:(1)Physical exercise motivation,physical exercise attitude,and physical exercise behavior all have a positive effect on the physical health of students,and the direct effects are 0.263,0.205,and 0.602 respectively,which are consistent with the results of previous studies by some scholars.(2)Physical exercise behavior plays an intermediary role between physical exercise motivation,physical exercise attitude and students' physical health,and the intermediary coefficients are 42.91% and 48.23%,respectively.(3)There is a covariant relationship between physical exercise motivation and physical exercise attitude,with a correlation coefficient of 0.255,and a covariant relationship between internal exercise motivation and exercise attitude,with a correlation coefficient of 0.375.Research conclusions:(1)In terms of physical exercise motivation,the amount of variation that can be explained by external exercise motivation is relatively high,indicating that the students of higher vocational colleges in Hunan Province are affected by system motivation,Obedience motivation has a greater impact,which may be related to the requirements of the school,the student's own sports goals,and the hopes of relatives and friends.(2)In terms of physical exercise attitude,the amount of variation that can be explained by the attitude of the exercise process is higher.The possible reason is that with the progress of the exercise stage,students' evaluation of exercise is getting higher and higher,and the degree of automation is getting higher and higher.After a profound emotional experience,he gradually recognized the "healthy running" activity.(3)In terms of physical exercise behavior,the amount of variation that can be explained by long-term exercise behavior is relatively high,indicating that compared with the pace and time of daily exercise,the development of physical exercise habits should be the direction that school decision-makers need to pay more attention to.,Because only long-term persistence,the exercise effect can be more apparent.(4)Physical exercise behavior plays an intermediary role between physical exercise motivation,physical exercise attitude and students' physical health,and the intermediary coefficients are 42.91% and 48.23%,respectively.This shows that physical exercise motivation and physical exercise attitude have played a positive role in the physical fitness of college students.On the other hand,physical exercise motivation and physical exercise attitude orientation have promoted college students' physical exercise behavior and transformation to a certain extent.To improve the physical health of students.(5)There is a covariant relationship between physical exercise motivation and physical exercise attitude,the correlation coefficient is 0.255,and there is a covariant relationship between internal exercise motivation and exercise process attitude,and the correlation coefficient is0.375.In other words,physical exercise motivation and physical exercise attitude can influence each other.If the student's physical exercise motivation is relatively high,then his physical exercise attitude will also be relatively high;if the student's physical exercise motivation is relatively low,then his physical exercise attitude It will also be lower.The research puts forward:(1)Pay equal attention to multiple measures to strengthen students' motivation for physical exercise;(2)Pay attention to daily management and improve students' attitudes towards the exercise process;(3)Build a large database to standardize students' physical exercise behavior;(4)Construct institutional space and improve Student exercise safeguard measures. |
