It is well recognized that regular physical activity may improve cardiac autonomic regulation preventing chronic non-communicable diseases. Accordingly, the assessment of cardiac autonomic regulation (CAR) with non-invasive techniques, such as RR interval Variability (V) might be of practical interest. We studied 56 soccer players (21.2 ± 4.2 years.) and 56 controls (22.2 ± 1.5 years.) and used a ranked Autonomic Nervous System Index (ANSI), resulting from the combination of multivariate statistical methodologies applied to spectral analysis derived indices from RRV. We hypothesized that ANSI would be higher in soccer players as compared to controls ( < 0.001) and that values would be greatest in defenders and midfielders, who are known to run longer distances during competitions. Conversely in the intrinsically stationary goalkeepers ANSI would be similar to controls. Our data show that it is possible to assess the overall level of autonomic performance in soccer players as compared to the general population, using a ranked composite autonomic proxy (ANSI). This approach suggests as well that CAR is better in those players who during competitions run for a greater distance. We conclude that it is possible to highlight the differences in autonomic profile due to distinct exercise routines, using ANSI, a simple ranked, composite autonomic proxy.
众所周知，有规律的体育活动可以改善心脏自主调节功能，预防慢性非传染性疾病。因此，使用非侵入性技术评估心脏自主调节（CAR），例如 RR 间隔变化（V）可能具有实际意义。我们研究了 56 名足球运动员（21.2 ± 4.2 岁）和 56 名对照者（22.2 ± 1.5 岁），并使用了一个等级自主神经系统指数（ANSI），该指数是通过将多变量统计方法应用于从 RRV 衍生的频谱分析指数而得出的。我们假设 ANSI 在足球运动员中会高于对照组（<0.001），并且在众所周知在比赛中跑动距离更长的后卫和中场球员中，其值会更高。相反，在本质上是固定的守门员中，ANSI 与对照组相似。我们的数据表明，使用等级复合自主代理（ANSI），可以评估与一般人群相比足球运动员的整体自主表现水平。这种方法还表明，在比赛中跑动距离更长的运动员中，CAR 更好。我们得出结论，使用 ANSI 这种简单的等级复合自主代理，可以突出由于不同的运动习惯导致的自主特征差异。
