热辐射大差异环境下运动员抗寒响应的医学分析

Medicine Analysis of Athletes Cold Resistance Response Under Difference Thermal Radiation Environment

当前的运动员抗寒分析模型,仅面向单一热辐射环境进行分析,无法在大差异热辐射环境下构建有效的运动员体表抗寒模型,不能对运动员的抗寒响应进行准确的分析,提出一种考虑差异对流抗寒因素的运动员抗寒调整模型,获取不同热辐射环境与运动员对流抗寒系数间的关系,针对大差异热辐射环境对运动员抗寒的影响特征,塑造二维人体抗寒调整模型,采用数值方法对人体抗寒调整模型进行求解,实现了大差异热辐射环境下,运动员抗寒响应的有效分析。实验结果说明,不同热辐射环境下,所提方法分析的运动员体内和体表温度的动态响应趋势,同实测结果相对误差低于2%,具有较高的匹配度。

Current athletes cold analysis model, only for a single thermal environment were analyzed, and the thermal environment in large differences to build effective athletes surface cold model, cannot be accurately for athletes to cold response analysis, put forward a kind of thinking difference athletes cold adjustment model of convection of cold resistance factors, access to different thermal environment and the relationship between coefficient of convection cold athletes, in view of the big difference thermal radiation environment the influence of cold hardiness characteristics of athletes, the two-dimensional body cold adjustment model, the numerical method are applied to solve the cold adjustment to the human body model, realized the big difference between thermal environment, effective analysis of athlete cold response. Experimental results show that, under different thermal radiation environment, the proposed method to analyze the athletes and the dynamic response of the body surface temperature trends, with relative error less than 2%, the measured results with higher compatibility.
