| With the development of aging population,our country will face great pressure for retirement.As the proportion of the elderly population in the total population of society is increasing,we should pay more attention to the needs of this group.Sedentary behavior is a chronic health risk behavior that exists in all age groups,especially among the elderly.Sedentary behavior not only reduces exercise ability and increases the risk of disease in the elderly,but also indirectly leads to decreased self-care ability and increased risk of falls.Sedentary behavior of the elderly began to receive more attention recently,and relevant studies mainly focused on sedentary behavior at home and in nursing homes,while less attention was paid to sedentary behavior in outdoor space.Outdoor seating is an important external factor affecting the elderly sitting and standing up in the outdoor space.Through the design of outdoor seating,it is helpful to realize the intervention of outdoor sedentary behavior of the elderly.Therefore,with the purpose of the elderly outdoor sedentary behavior intervention,this paper explores the change barriers and seat needs of the elderly outdoor sedentary behavior,and puts forward targeted intervention strategies and corresponding seat design.Through the analysis of the theory of sedentary behavior intervention and related design cases,as well as the qualitative and quantitative investigation of the outdoor sedentary behavior of the elderly,the following conclusions are drawn.Firstly,the change barriers of outdoor sitting for the elderly were obtained,and then the elderly groups were divided into three types according to their population characteristics and existing barriers.Then,for three groups of elderly people,the corresponding sedentary intervention strategies were proposed.Finally,based on the intervention strategy and the aging design principle of outdoor seats,the outdoor seats and related products were designed respectively.Through the research of this subject,it provides a reference for people to understand the outdoor sedentary behavior of the elderly.Some intervention strategies related to seats proposed in this paper also provide some references for reducing the outdoor sedentary behavior of the elderly and promoting outdoor physical activity of the elderly. |
