太极拳呼吸方式对心率变异性的影响
首发时间:2012-01-20
摘要:目的:呼吸是心率变异的一个重要影响因素。本文欲通过检测高、低水平太极拳练习者的气体代谢指标和心率变异指标,探索太极拳呼吸方式对心率变异的影响。方法:采用芬兰Polar RS800及Cortex气体代谢分析仪对受试者练习简化24式太极拳过程中的心率变异情况和气体代谢指标进行记录,选取安静时5分钟均值、运动中全过程均值与运动后10分钟均值进行统计学计算。结果与结论:①长时间的太极拳练习使练习者的呼吸频率降低,潮气量增加。②长时间太极拳练习对练习者HF的调节能力有明显作用,使练习者的植物性平衡能力增强。③呼吸频率和潮气量对心率变异性的影响结果一致,即LF、HF及平均RR都出现随着呼吸频率和潮气量增加而降低,随着呼吸频率和潮气量减少而增大,LF/HF的变化相反。

Influence of the breathing manner of tai chi practition on heartrevariability
Abstract:Purpose: Respiratory is an important factor for heart rate variability. This paper will explore the breathing manner of tai chi practition on heartrevariability by detecting the gas metabolism and heart rate variability index of high and low levels of Tai Chi practitioners. Methods: using Polar RS800 and Cortex metabolic gas analyzer to record the variation of heart rate variability and metabolic indicators of gas of subjects to practice Taijiquan, selecting the mean value of 5 minutes quiet、the whole process of movement and 10 minutes after movement for statistical calculations. Results and Conclusion: ① long time tai chi practicing reduces breathing frequency and increases tidal volume.②long tai chi practicing plays a significant role on the ability to regulate practitioners'HF,to enable practitioners to enhance the balance of plant. ③The influences of respiratory rate and tidal volume on heart rate variability are consistent, that is, LF, HF, and the average RR have emerged as the respiratory frequency and tidal volume increase and decrease with reduced respiratory rate and tidal volume increases, LF / HF changes in contrast.
