Changes of blood rheology indexes and bifurcation shearing force after exercise
Tian Gui-ling
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.
<br> OBJECTIVE:To analyze the effect of exercise on blood rheology indexes and vascular dynamics.
<br> 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.
<br> 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.
