A Study Tracking Of Physical Activities Of The Elderly In Cities And The Built Environmental Factors Of Physical Activities Of The Elderly In Cities

Objective:(1)GPS combined with body activity accelerometer was used to track the sample population to objectively measure the spatial movement location distribution,location type,concentration area,and middle and high intensity fitness activity concentration area of the elderly daily life.(2)This paper analyzes the outdoor physical environment factors that affect the elderly people’s persistence in physical exercise,and analyzes the physical environmental factors in the planning and design of residential areas from the perspective of subjective perception,which provides a reference for the planning and design of residential areas.method:In Wucheng,Jindong,9 districts and 3 parks were randomly selected of Jinhua City.A questionnaire survey was conducted among the elderly aged 60 to 70(545 effective samples,232 males and 313 females),sex,age,marriage,Demographic information,such as education level,etc.The physical environmental factor survey scale developed by Zhou Rena and otherswas used to investigate the residential area and the surrounding physical activity environment.Two common GPS locators were selected,in the empty space,in the jungle,in the open road on both sides.On both sides of the street,80 people(40 males)were randomly selected in the short and long time interval sampling analysis of positioning accuracy of the residential district and the high-rise building.40 women wore a body motion accelerometer and a GPS locator(measured for 3 days for 7 consecutive days)with a valid sample size of 64(33 males and 31 females).The demographic information was described and analyzed.The location point space type adopts the GPS localization platform,Combined identification of electronic network maps and streetscape maps-calculation of location distance using longitude and latitude formulas-percentage statistics of location type and location location distance grade-consistent training years using an ordered logistic regression analysis.And physical environmental awareness.Result:(1)The GPS positioning accuracy shows that short interval sampling can not improve the positioning accuracy,but it is easy to identify the static state(the location points overlap.There are differences in the positioning accuracy between different locators at the same location and the same locators at different locations.The average positioning error is between 6 and 45 meters,and the height of the building is an important interference factor in the positioning accuracy of GPS.However,the micro-tracking of local space(such as the running track of soccer field)should avoid the influence of surrounding high-rise buildings.(2)A total of 67.1%of the 17292 outdoor activity locations collected from the sample were accumulated within 1000 meters of 600 meters from the center of the district.In the space type,the area occupied 54.5%,the travel track along the street accounted for 33.7%,the park/green space/square outside the residential area was open space.Accounts for 0.8,outside the community sports and exercise facilities accounted for 0.8,shopping malls or entertainment accounted for 1.5.(3)The sample collected 531 activity location points of moderate and high intensity exercise.76.6%of them have accumulated 84.19%within 1000 meters of 600 meters from the center of the district.In the space type of the activity point of medium and high intensity exercise,39.9%of the space type,42.2%of the street travel track,the area with the.Outside the park/green space/square and other open space accounted for 10.4,outside the area of sports and exercise facilities accounted for 3.6,shopping malls or entertainment accounted for 4.0.(4)Logistic regression analysis showed that the green district is the main factors affecting the physical environment of exercise to male samples(beta =0.593,P=0.031),and the influence of the main physical environment sample of women exercise factor is the whole area and the surrounding environment(beta =0.528,P =0.022)and the vehicle speed within the cell(beta =0.744,P=0.003).Conclusion:(1)The daily activity space in Jinhua city at the age of 60-70 elderly people are mainly concentrated in the area and the surrounding 600 meters,600 meters range of sports facilities in the center of radiation area and other public service facilities contribute to the elderly physical activity.(2)High-intensity physical exercise among the 60-70 year-old people in Jinhua urban area is mainly concentrated on the path along the road.Walking or cycling is an important source of medium and high intensity physical activity.In the future,the intervention of physical exercise for the elderly should focus on the path along the road and the community.Attention should be paid to the rational planning and construction of cycling lanes and sidewalks and the construction of physical exercise facilities in small areas,which may be more conducive to the active exercise of the elderly than the construction of large-scale stadiums(pavilions/centers).(3)The main physical environmental factors that affect the elderly aged 60-70 years in Jinhua City are greening landscape,overall environmental quality and the speed of traffic flow in the district.It is suggested that the green landscape of the district should be perfected.Limit the speed of motor vehicles or build passenger-car shunt areas to promote the elderly to participate in active exercise.(4)According to the characteristics of activity space and physical environment of the elderly in Jinhua urban area,it is suggested that the evaluation index of the residential area suitable for the elderly should be mainly from the physical exercise facilities,community greening and landscape.The design of motor vehicle speed limit or passenger car shunt,the distribution of public service facilities(physical exercise facilities,vegetable markets,hospitals,supermarkets,barbershops,etc.)within 600 meters of pedestrian walkways and bicycle lanes.
