 不同水平青老年太极拳练习者练习过程中 心率变异的变化# 熊开宇，何辉，吕媛媛* 5 10 15 20 25 30 35 40 （北京体育大学教学实验中心，北京 100084） 摘要：心率变异性(heartrevariability，HRV)，是 80 年代末至今比较受关注的无创性心电 监测指标之一。HRv 分析可用来评价心脏自主神经的活动性及相关病理状态。目的：本研究 希望较系统对太极拳练习者在太极拳练习不同阶段与恢复期心率变异性的规律进行深入研 究。方法：应用心率变异方法分别对青老年高水平组各 10 人、青老年普通组各 10 人作为对 照组进行太极拳练习过程中心率变异变化的比较。结果：青年实验组平均 RR 间期、RLX 基 线、SD1、RMSSD 等时域显著性高于青年对照组，老年实验组（AT）与老年对照组（AN）RLX 基线、SD1、RMSSD 安静、运动与恢复期均无显著性差异，训练对于练习者 LF/HF 有显著性 影响。 关键词：不同水平；青老年；太极拳；心率变异 中图分类号：G804.2 Young and elderly tai chi practitioners of different levels of HRV change during exercise XIONG Kaiyu, HE Hui, LV yuanyuan (Beijing Sport University Teaching Experiment Center, Beijing 100084) Abstract: HRV has been more concern non-invasive diagnosis of ecg monitoring indexes since the end of the 80 s. HRv may be used to evaluate the activity of the heart’s autonomic nervous and relevant pathological state.PURPOSE: The aim of this study is for HRV’s dispiline change of tai chi chuan practitioner in different stages and recovery.METHODS: In this study, take young and old 10 high-level Tai chi practitioners as experimental group, young and old age of 10 general practitioners as the control group, the comparison of the variation rate changes.RESULTS: Youth Training Section quiet and convalescent mean RR interval was significantly higher than young control group, RLX baseline, SD1, RMSSD quiet significant indicators of recovery were higher than the general practitioner movement. The old experimental group and control group between the average RR intervals, RLX baseline, SD1, RMSSD there was no significant difference. Tai Chi exercises for practitioners in a long time LF / HF were significantly affected by Hf changes, HF may have significant effect on the ability to regulate and functional changes in HF has led to a long time practicing Tai Chi practitioners balance recovery plant may be better than general practitioners.
