The exercise training has positive impact on autonomic nervous system (ANS) activity. However, specific type of these changes significantly depends on intensity of used physical exertion.
To assess the influence of long-term and single moderate physical exertion on ANS function in young athletes.
Sixteen middle-aged, 19-34 years old (24 +/- 5) athletes were included in the study. Assessment of ANS parameters (baroreflex sensitivity--BRS-WBA, heart rate variability--HRV) and mean heart rate period (mean HP) were calculated three times: recording 1--during the final stage of training period, recording 2--60 minutes after single moderate exertion, recording 3--after 2 months of training before competitions.
In the whole group, significant increase of TP, HF SDNN and rMSSD indices was found in recording 2 comparing to recording 1, whereas after 2 months of intensive training no statistically significant changes were observed. In the group of athletes training only endurance sport (12 persons) in recording 2 the significant increase of TP, HF, SDNN, rMSSD and BRS-WBA was found. After 2 months of intensive training, no changes of these parameters were observed.
In response to long-term training cycle with increasing intensity, preparing athletes for competitions, no significant changes of measured ANS parameters were found, which may indicate lack of overtraining during such a high intensity of training, and its safety. The changes of ANS parameters indicating increase of parasympathetic nervous system function after single exertion with moderate intensity (65% of maximum heart rate) were observed.
运动训练对自主神经系统（ANS）活动有积极影响。然而，这些变化的具体类型很大程度上取决于所采用体育锻炼的强度。
评估长期和单次适度体育锻炼对年轻运动员ANS功能的影响。
16名年龄在19 - 34岁（24±5）的中年运动员纳入研究。自主神经系统参数（压力反射敏感性——BRS - WBA、心率变异性——HRV）和平均心率周期（平均HP）的评估进行了三次：记录1——在训练期的最后阶段，记录2——单次适度运动后60分钟，记录3——在比赛前2个月的训练后。
在整个组中，与记录1相比，记录2中TP、HF SDNN和rMSSD指数显著增加，而在2个月的强化训练后未观察到统计学上的显著变化。在仅进行耐力运动训练的运动员组（12人）中，记录2时发现TP、HF、SDNN、rMSSD和BRS - WBA显著增加。2个月的强化训练后，这些参数没有变化。
在为比赛做准备的强度不断增加的长期训练周期中，未发现所测量的自主神经系统参数有显著变化，这可能表明在如此高强度训练期间没有过度训练，且训练是安全的。观察到单次中等强度（最大心率的65%）运动后自主神经系统参数的变化表明副交感神经系统功能增强。
