A Theoretical Study Related To Risk Assessment Of Aging People Participating In Badminton

The demographic structure of China’s society is in a critical stage of change,and the number of aging people has continued to increase dramatically over the years,the establishment of an aging sports risk assessment system is of great theoretical guidance and realistic use value for the steady promotion of the older fitness cause.Badminton has been introduced to China by overseas Chinese since the last century and has been widely welcomed by the public because of its skillful and flexible technology,which makes the confrontation across the net interesting and has been held for thirty-four consecutive years since 1986.Therefore,this paper focuses on the construction of the risk assessment system of badminton for the aging and proposes response strategies based on the scientifically constructed risk assessment system of badminton for the older.Firstly,the basic theories were sorted out through the literature,and the basis of risk factor construction and the principles to be followed were established by drawing on risk management theory and preamble methods;the initial identification of the risk list of badminton for the elderly established based on literature and deep mining of theoretical knowledge was carried out by using expert interviews,and four risk sources of badminton for the elderly were established.Then,the exploratory factor analysis method was used to establish structural relationships among the risk indicators of badminton for the elderly initially validated by experts,and 10 representative risk factors and 35 specific risk indicators were extracted.Finally,stepwise multiple regression analysis was used to test the predictive index system of the initially identified risk factors,and four stepwise regression linear models were constructed with the primary risk source as the dependent variable and the risk factor as the independent variable,and by analogy,10 stepwise regression linear models were constructed with the subordinate risk indicators with the risk factor as the independent variable.The results obtained 14 regression models,R-value rate all meet the requirements,risk indicators P<0.001<0.05,based on which four risk sources were constructed: the elderly own risk,environmental risk,badminton technical risk,public safety,and security risk.10 risk dimensions: physiological conditions,sports behavior,professional knowledge,natural environment,site environment,mobile footwork,hitting technology,doubles cooperation,the safety precautions,injury relief.31 specific risk indicators: chronic sports injuries,preparation and warm-up before exercise,risk perception etc.the risk assessment index system of badminton for the elderly.And according to the quantitative coefficient values of risk indicators in the construction model and the degree of impact of injury to propose specific response strategies,such as the purchase of sports accident insurance for the elderly will be transferred to the risk;sports clubs in conjunction with the community for the elderly to hold learning seminars to improve risk perception and other mixed strategiesThe index system has a clear structure and can effectively reflect 85.977% of the total risk of badminton for the elderly.Public safety and security should focus on the work of injury relief;the elderly themselves should pay more attention to factors related to physiological indicators;environmental risks in the higher impact of the site risk;badminton technical risks related to stroke technique should be given attention.
