为了评价运动对主动脉壁弹性和弹性成分的影响，对年轻雄性大鼠进行了16周的不同运动方案。运动大鼠在生理应变下，主动脉增量弹性模量显著降低。运动组主动脉弹性蛋白含量显著增加，弹性蛋白钙含量显著降低。运动组和久坐组的累积数据显示，弹性蛋白钙含量与增量弹性模量呈正相关。我们的结论是，体育锻炼从早期的年龄减少钙存款在主动脉壁弹性蛋白，这种影响可能会产生在运动大鼠扩张的主动脉。
SummaryTo evaluate the effects of exercise on aortic wall elasticity and elastic components, young male rats underwent various exercise regimes for 16 weeks. In the exercised rats, the aortic incremental elastic modulus decreased significantly when under physiological strain. The aortic content of elastin increased significantly and the calcium content of elastin decreased significantly in the exercised group. The accumulated data from the exercised and sedentary groups revealed that the elastin calcium content was related positively to the incremental elastic modulus. We concluded that physical exercise from an early age decreases the calcium deposit in aortic wall elastin and that this effect probably produced in the exercised rats a distensible aorta.
