酒后运动对心血管功能的影响

Effects on cardiovascular functions of exercise after drinding a bottle of beer

目的通过对酒后运动时心血管血流参数的观察，探讨酒后运动对心血管功能的影响。方法采用 TP－ CBSⅠ型无创心血管血流参数（心功能）检测仪，记录研究了受试者饮用啤酒后运动时心血管功能的变化。结果与饮水对照相比，饮酒后可导致安静状态下平均动脉压升高、心率增加、搏出量减少及血管顺应性的降低；酒后运动可导致心率增加、心搏量减少、心搏指数降低、外周阻力增加、血管顺应性降低，且恢复减慢。结论酒后运动可导致心功能降低、血管弹性下降、阻力增加。

Objective This study has been carried out so as to explore the effects on cardiovascular function of exercise after drinking a bottle of beer. Methods The parameters of cardiovascular functions have been recorded and analyzed with TP－ CBSⅠ heart function instrument in objects in different times and states(in rest and after a exercise on bicycle ergometer: 1500Kgm.min－ 1、 60rpm、 5min). Results In relative rest, the beer could let the mean blood pressure and heart rate increase significantly (P< 0.05), but the heart stroke volume and vascular compliance decrease significantly (P< 0.05) in comparing with water. In the state of exercise, the beer could induce the heart rate and the peripheral resistances increase significantly (P< 0.05), and the heart stroke volume and the heart stroke index and vascular compliance decrease significantly (P< 0.05). All changes above－ mentioned come back slowly (P< 0.05). Conclusion The exercise after drinking a bottle of beer could induce the function of heart and the vascular elasticity drop down, and the peripheral resistances go up.
