Analysis On The Differences Of Exercise Behavior Of Sports People In Urban Parks

In modern society,as people's living conditions have been improved greatly,they have started to pay attention to their individual healthy conditions.By providing a place for people to get close to the nature,take part in sports activities so as to relax their body and mind,the city park concerns a lot to the urban natural environment,cultural environment and physical and psychological health of urban residents.The issue of building city parks has been applied to extensive researches in literature related to the urban planning.Through the document retrieval,it is found that studies on physical exercise difference in the sports science are made mainly from five aspects including gender,family background,living environment,social stratum and exercise phase.While there have no studies on difference between exercise behaviors in geography.The South Lake Park of Nanning city,one of the demonstration projects of“Sponge City”,owns a convenient traffic facilities around it,having attracted many people to take exercise here from all walks of life.Thus it is typical to take the South Lake Park as the research region.The method of questionnaire survey is adopted to collect information about people coming to South Lake Park to take exercise so as to study on the exercise behaviors of them while the variance method and chi-square test method are used to analyze the difference features about the exercise behaviors of different crowds taking exercises.Besides,the structural equation model is selected to study on the system of influence of working stress,family background,social activities,physical conditions,exercise places and health consciousness on the exercise behavior differences.This paper also uses Logistic regression analysis to find out influence factors about the situation that people change their plans of going out due to PM_2.5 concentration by analyzing the cognitive difference of different crowds on PM_2.5 and combining with the field measurement for PM_2.5concentration data of the park.That is how this paper can analyze the health risks existing in the exercise process of ill crowds taking exercises in the park.The research results are as follow:?1?people coming to this park for exercise are mainly resigned personnel and retiree over 60 years old,in which people retired from the public institutions and civil servants occupy the largest number,the number of people who work as a freelancer,student,company employee,service staff and marketing personnel is similar to that of one another.Besides,most of these people hold a degree of bachelor or junior college and more than half of them have a weight within the abnormal range.?2?People who are older have more opportunities to take exercises,among which people within 31-40 year old and 51-59 year old take exercise in a more fierce way.People coming to take exercise in this park with different ages take parks as their major training place while people aging from 31 to 40 tend to choose paid sports places to take exercises.As the age gets older,the number of people who take exercise mainly to build their bodies has increased while the number of people who take exercises to lose weight and relax themselves has reduced.?3?There is no significant difference in the time coming to take exercise,exercise duration and exercise frequency between male and female sports group for they mainly parks as their exercise place.However,male sports group tends to take exercise at home and in paid exercise places compare to female.Some people in the male and female sports group will extend their exercise duration at weekend.Besides,male group taking exercises sticks to come to park for exercise so their time for exercise in park appears more longer than that of female.The exercise goals of male and female sports group prove no obvious difference.?4?Among the exercise crowds from all occupations,people who have resigned and retired from their job and who work in the public institutions as well as self-employed people and freelancers have more chances to take exercises among which administrative staff of enterprises and public institutions,staff in the public institutions and students take exercises in a more intense way.While most of the crowds coming from various works come to this park for exercise alone and people who have a job with more leisure time prefer to exercising ways which are slow.People from all walks of life mainly choose the park as their exercising place while the public institution staff,administrative staff in enterprises and institutions,company employees,service staff,marketing personnel,self-employed people and freelancers tend to come to paid exercising places to take exercises.In addition to students and workers,the other crowds take exercises mainly to build their bodies.?5?The crowds with a higher educational background have less opportunities to take exercise but their exercising way is more intense and they will make plans for their exercise activities.Moreover,they will take exercises in diverse places.There appears no obvious difference in exercise goals between crowds having different educational backgrounds for they take exercises mainly for body building.?6?Such factors as working stress,social activities,physical conditions and exercise places will exert a prominent influence on exercise behavior difference in which the physical conditions have the largest effect on exercise behavior difference while the exercise places have the minimum effect on exercise behavior difference.?7?According to the result of the field measurement,points in the southeast direction of the South Lake Park have a higher value of PM_2.5 than points in the northwest direction of the park and PM_2.5 concentration appears higher at night than in the morning.Besides,male have a better understanding of the hazards of PM_2.5 than female.People who have received higher education tend to have a better understanding of PM_2.5 harms.Managers in enterprises and institutions and students have a stronger awareness to avoid being harmed by PM_2.5.After calculation,the factors affecting whether people change their plans of going out due to PM_2.5concentration are as follow:people's schooling conditions,whether they pay close attention to PM_2.5 and the weather forecast,whether they are equipped with anti-air pollution device and whether they know that the PM_2.5 is harmful to cardiovascular conditions and respiratory system.According the survey result,it is found that people who with respiratory or cardiovascular diseases have a weak awareness of healthy exercise for they failed to choose scientific exercise time and ways based on their physical conditions and the park's environment.
