The positive effects of physical training on heart rate variability (HRV) in healthy adults are widely recognized; however, the responsiveness to training in healthy children has not yet been established. The aim of this study was to determine the influence of physical training on HRV in prepubertal healthy children. Systematic computerized searches were performed from 1950 to 2012 in the following databases: Medline, Embase, Cinahl, Lilacs, Scielo, SportDiscus, ProQuest; Web of Science; PEDro; Academic Search Premier and the Cochrane Library. The key words used were: heart rate variability, autonomic nervous system, exercise training, physical activity, continuous exercise, intermittent exercise, children, prepubescent, adolescents, and healthy. Although the database search initially identified 6,164 studies, after removing duplicates and excluding by title the number was 148, however, only 2 studies were included in this systematic review. The meta-analysis compared the experimental group (n = 29) with the control group (n = 28) for the HRV parameters: RR intervals, SDNN, RMSSD, pNN50, LF (log), HF (log), LF/HF and Total Power (log). The meta-analysis demonstrated similar HRV indices between both the experimental and control groups. In conclusion, the available results from randomized controlled trials do not support the hypothesis that physical training improves HRV in healthy children[AUQ2].
体育锻炼对健康成年人心率变异性（HRV）的积极影响已得到广泛认可；然而，健康儿童对锻炼的反应性尚未确定。本研究的目的是确定体育锻炼对青春期前健康儿童HRV的影响。我们于1950年至2012年在以下数据库中进行了系统的计算机检索：医学文献数据库（Medline）、荷兰医学文摘数据库（Embase）、护理学与健康领域数据库（Cinahl）、拉丁美洲和加勒比地区卫生科学数据库（Lilacs）、科学电子图书馆在线数据库（Scielo）、体育与运动科学全文数据库（SportDiscus）、ProQuest数据库；科学引文索引数据库（Web of Science）；循证医学数据库（PEDro）；学术搜索高级版数据库（Academic Search Premier）和考克兰图书馆。使用的关键词有：心率变异性、自主神经系统、运动训练、体育活动、持续运动、间歇运动、儿童、青春期前、青少年和健康。尽管数据库检索最初识别出6164项研究，但在去除重复项并通过标题排除后，数量为148项，然而，本系统评价仅纳入了2项研究。荟萃分析比较了实验组（n = 29）和对照组（n = 28）的HRV参数：RR间期、标准差（SDNN）、相邻RR间期差值的均方根（RMSSD）、差值大于50ms的相邻RR间期对数占总RR间期对数的百分比（pNN50）、低频功率（LF，对数）、高频功率（HF，对数）、LF/HF和总功率（对数）。荟萃分析表明，实验组和对照组之间的HRV指标相似。总之，随机对照试验的现有结果不支持体育锻炼可改善健康儿童HRV这一假设。
