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 evaluate the effects of natural healing factors such as mineral springs on the autonomic nervous system by observing the changes of heart rate variability (HRV) and blood pressure variability (BPV). Methods Fifteen healthy male health-care pilots during the convalescence were selected as subjects and randomly divided into control group, spa group and mineral spring swimming group. HRV and BPV were analyzed before and after exercise. Results The HRV index showed that the LF / HF of the bath group was significantly lower than that of the exercise group, LF and LFn of the mineral bath group and the mineral water swimming group decreased, and HF and HFn tended to increase , No significant change in the control group. After exercise, compared with the control group, mineral water group supine position HF, HFn increased significantly, LF / HF decreased significantly. BPV indicators before and after exercise no significant change, no significant difference between groups. Conclusions Mineral bath and swimming can increase the level of cardiac vagal activity, the effect of mineral bath is more obvious.
