摘要
本文利用多普勒超声仪分别对50名常年冬泳锻炼的老年人和48名无冬泳锻炼史的老年人在安静状态、3 min台阶实验后、台阶试验结束恢复5 min后的心脏指标进行测定。结果表明:多年冬泳锻炼老人心脏的LVDd I、LVDs I、IVSs I、LVPWs I指标明显优于对照组;心脏的泵血功能和收缩功能都显著提高;左心室增大,心肌重量及重量指数增加,从而缓解舒张能力。通过常年冬泳锻炼,有助于老年人心血管系统耗能降低,心率储备能力和心脏功能得到适应性提高。
This paper used Doppler echocardiography to determinate the cardiac indexes of 50 elders with perennial winterswimming and 48 non elderly winter swimming history in the quiet state, 3 min after the end of step experiment, heart indexrecovery after 5 min level tests, respectively. The results showed that LVDdI, LVDsI, IVSsI, LVPWsI of elders with perennialwinter swimming were better than those in the control group, the pumping and systolic function of the heart increasedsignificantly; the left ventricle increases, the weight and weight index of the myocardium increase, thus relieving diastolicability. The perennial winter swimming can help reduce energy consumption of cardiovascular system of elders, their heartrate reserve and heart function are improved accordingly.
