高原区运动与心肺功能的关系模型仿真

Relational Model Simulation of Tg-p Movement and the Cardiopulmonary Function

在高原地区的运动环境下,心肺功能的参数会发生与正常区域不同的异常变化。心率、动脉血压、呼吸最大的特征是发生不规律突变。传统的心肺参数分析模型必须要求参数平稳,或者要求参数异常变化的规律性,一旦,发生参数无规律变化,模型会迅速陷入不收敛,无法有效完成建模过程。为建立正确的高原心肺功能模型,提出一种考虑心肺参数异常交互变化的分析模型,并应用到高原区运动对心肺功能的促进分析中。以人体生理学为基础,就高原区运动对心肺系统性影响进行关系建模仿真研究,建立高原区运动对心肺功能促进模型,通过模型进一步分析了高原区运动对心肺感受性反射变化与呼吸作用相关的心率、血压变异性,并作为分析的约束条件,对传统模型进行优化。仿真结果表明,改进的关系建模方法能够较为精确的反映高原区运动对心肺系统的影响,为高原区体育训练提供了准确的理论基础。

In plateau area of sports environment, the parameters of cardiopulmonary function will happen with norreal abnormal changes in different area. The greatest feature of the heart rate, arterial blood pressure and breathing is irregular mutations. Traditional cardiovascular parameters must demand that the analysis model is smooth, or require parameters abnormal change regularity, once, the parameters of the irregular change, model will rapidly convergence, which is unable to finish the modeling process effectively. A varied analysis model with anomaly interaction of eardiopulmonary parameters is presented and applied to the analysis of the tg-p movement for the promotion of cardiopulmonary function. Based on human physiology, tg-p exercise on eardiopulmonary function promote model is established. Through the model, the movement of cardiopulmonary tg-p sensitivity reflects changes of heart rate, blood pressure variability associated with respiration are further analyzed, and as the constraint conditions, the traditional model is optimized. The simulation results show that the improved modeling method can accurately reflect the relationship between tg-p movement influence on cardiopulmonary system.
