长期太极拳练习者脑血流动力学的经颅多普勒检测

Influence of Long-term Taijiquan Exercise on Cerebral Hemodynamics Detected by Transcranial Doppler

为探讨长期太极拳练习对中老年人脑血流状况的影响。应用经颅多普勒 (TCD)对 1 9例长期太极拳练习参加者和 1 7例相应年龄无锻炼经历者脑底动脉环各血管的收缩峰速度、舒张峰速度、平均速度、搏动指数等脑血流动力学指标进行检测和对比。结果表明 :1 )练习组在ACA、MCA、PCA等动脉 ,VP、VM、VE等指标显著高于对照组。 2 )BA、VA的各项指标在两组间无显著性差别。 3)Pi指数两组间各动脉均无显著性差异。结论

The paper is to evaluate the influence of long-term Taijiquan exercise on cerebral hemodynamics of the elder people by using EMS-9 transcranial Doppler, detected the VP, VM, VE and the PI of the ACA, MCA, PCA, BA, VA. These indexes are compared between exercise group and non-exercise group. The results show that there are significant differences between exercise group and non-exercise group at VP, VM, VE of ACA, MCA, and PCA, but there are no significant difference between these two groups at all in the indexes of BA and VA. It can be concluded that by comparing with non-exercise group, the cerebral hemodynamics of the elder people who do long-term Taijiquan exercise have obvious improvement.
