PM2.5严重超标下户外运动的风险评估模型设计研究

摘要

Taking outdoor sports when PM2.5exceed the standard may lead to risk of lung disease. The risk assessment model of outdoor sports is established analysis of the relationship between the parameters of body function index and PM2.5content of out-door sports through quantitative, mathematical modeling, the guidance of outdoor sports exercise. The maximal oxygen analysis quantitative recursive PM2.5seriously exceed the standard risk assessment under the outdoor sports model based on constraint pa-rameter evaluation. Outdoor sports risk,using the template parameter control method and quantitative analysis method for risk as-sessment of recursive optimization with fuzzy decision method for risk assessment modeling of PM2.5exceed the standard environ-ment of outdoor sports,achieving the maximum oxygen uptake,the optimal maximum ventilation parameters,and thus the guid-ance of outdoor sports training.%PM2.5严重超标下进行户外运动可能会导致肺部疾病的风险,建立户外运动的风险评估模型,通过定量分析PM2.5含量与户外运动的身体机能指标参量的关系,实现数学建模,指导户外运动锻炼.提出基于最大摄氧量定量递归分析的PM2.5严重超标下户外运动的风险评估模型.构建户外运动风险评估约束参量,采用模板参数对照法和定量递归分析方法进行风险评估优化求解,结合模糊决策方法进行PM2.5超标环境下的户外运动的风险评估建模,求得最大摄氧量、最大通气量等参数的最优值,从而指导户外运动训练.
