摘要:

背景:运动后血液流变的异常是产生运动疲劳的原因之一,也是运动诱发心血管疾病的危险因素之一。

目的:分析运动方式对血液流变指标和血管动力学的变化规律。
方法:建立血管模型并采用有限元法分析一次性力竭运动和系统运动两种运动模式下分叉血管剪切力分布,检测30名健康大学生志愿者血液流变指标。在查阅文献的基础上,通过实验和理论分析运动方式对血液流变性的影响,及运动方式与血管剪切力之间的相关关系。

结果与结论:一次性力竭运动能使机体血液流变性明显发生不良变化,而长期规律的系统运动后明显改变血液流变性均有向好方向发展的趋势。一次性力竭运动后,分叉血管剪切力在分岔处小于0.6 Pa;系统运动后,血管处剪切力为0.6-1 Pa。因此,一次性力竭运动后易诱发血管疾病;系统运动起到预防血管疾病的作用。

Abstract:

BACKGROUND: The abnormal blood rheology after exercise is one of the leading causes of exercise fatigue, and also a risk factor of exercise-induced cardiovascular disease.

OBJECTIVE: To analyze the effect of exercise on blood rheology indexes and vascular dynamics.
METHODS: The blood vessel models were established. The bifurcation shearing force was analyzed in the exercise modes of one-time exhaustive exercise and systemic exercise. The blood rheology indexes among
30 healthy volunteers were detected. Based on the consulting literatures, we observed the effect of exercise mode on blood rheology through experiment and theoretical analysis, and investigated the correlation between exercise mode and bifurcation shearing force.
RESULTS AND CONCLUSION: One-time exhaustive exercise had adverse effects on blood rheology, while system exercise significantly changed blood rheology. The bifurcation vascular shear stress was less than 0.6 Pa after one-time exhaustive exercise, and about 0.6-1.0 Pa after system exercise. Therefore, one-time exhaustive exercise induces vascular disease; system exercise can prevent vascular diseases.
