心率变异性(Heart rate variability HRV)是指窦性心律在一定时间内周期性改变的现象,是反映交感神经-副交感神经张力及其平衡的重要指标,对HRV进行分析可以间接评估心脏交感、迷走神经的紧张性及均衡性,研究表明心率变异信号中蕴含着有关血管活动的大量重要信息,因其无创、准确、简易的特点,近年已被广泛的应用于体育领域,文章重点对HRV在体育领域的研究现状进行宏观概括和细致综述。
Heart rate variability (HRV) refers to the phenomenon that sinus rhythm changes periodically within a certain period of time and is an important index reflecting sympathetic-parasympathetic tone and its balance. Analyzing HRV can indirectly evaluate cardiac sympathetic and vagus nerve The study shows that heart rate variability signals contain a great deal of important information about blood vessel activity. Because of its non-invasive, accurate and simple features, it has been widely used in sports field in recent years. The article focuses on the HRV in the field of sports The research status of the macro-summary and detailed overview.
