自然疗养因子矿泉对飞行员心率、血压变异性影响的研究

Effects of natural convalescent factors on heart rate and blood pressure variability of pilots

目的通过观察心率变异性(HRV)、血压变异性(BPV)的变化评价自然疗养因子矿泉等综合作用对自主神经调节的影响。方法选取疗养期间15名健康男性疗养飞行人员作为受试者,随机分为对照组、矿泉浴组、矿泉游泳组,于锻炼前后进行HRV与BPV分析。结果HRV指标表明,与锻炼前相比,矿泉浴组平卧位LF/HF显著降低,两种体位下矿泉浴组与矿泉游泳组的LF、LFn呈降低趋势,HF、HFn均呈升高趋势,对照组无明显变化。锻炼后与对照组相比,矿泉组平卧位HF、HFn较显著增加、LF/HF显著降低。BPV各项指标锻炼前后无明显改变,组间对比也无显著性差异。结论矿泉浴与游泳均可增加心脏迷走神经活动水平,矿泉浴的效果更为明显。

Objective To assess the comprehensive effects of natural convalescent factors on autonomic nerve regulation by obser- vation of the changes of HRV（heart rate variability）and BPV（blood pressure variability）. Methods 15 health male pilots enrolled as subjects during recuperation were randomly divided into control group, spring bath group and mineral spring swimming group.HRV and BPV were analyzed before and after training. Results HRV analysis showed that LF/HF of the spring bath group atter training was significantly lower than that before training.LF and LFn of the spring bath group and mineral spring swimming group showed a tendency to decrease in both supine and upright, while HF and HFn a tendency to increase.There was no significant difference of these indices of the control group.Compared with the control group, I-IF and HFn increased significantly and LF/HF decreased signif- icantly of the spring bath group after training in supine.There was no significant difference of indices of BPV before and after train- ing.There were also no significant differences among groups.Conclusion Both spring bath and spring swimming can increase the lev- el of cardiac vagal activity.The effect of the spring swimming group is better.
