【摘要】：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。
[Abstract]:The parameters of cardiopulmonary function are different from those in normal areas under high altitude exercise environment. Irregular mutations in heart rate, arterial blood pressure, and respiration are most characteristic. The traditional cardiopulmonary parameter analysis model must require the stability of parameters or the regularity of abnormal change of parameters. Once the parameters change irregularly, the model will quickly fall into non-convergence and can not complete the modeling process effectively. In order to establish a correct cardiopulmonary function model at high altitude, an analytical model considering the abnormal interaction of cardiopulmonary parameters was proposed and applied to the analysis of cardiopulmonary function promoted by exercise in high altitude area. On the basis of human physiology, the relationship between exercise and cardiopulmonary function was modeled and simulated, and the model of promoting cardiopulmonary function by exercise in high altitude was established. The heart rate and blood pressure variability related to the changes of cardiopulmonary reflex and respiration in exercise in high altitude area were further analyzed by the model, and the traditional model was optimized as the constraint condition of the analysis. The simulation results show that the improved relational modeling method can accurately reflect the influence of exercise on the cardiopulmonary system and provide an accurate theoretical basis for sports training in the plateau area.
