【摘要】：目的:探讨每周训练时长与吸烟两个潜在的自主神经功能影响因子对健康青壮年男性心率变异性(HRV)的交互影响,为改善青壮年男性人群自主神经功能、降低心血管疾病发病率提供相应参考。方法:本研究共选取了149例受试者,依据受试者吸烟指数的大小分为不吸烟组(N组,n=66例)、吸烟多组(M组,n=45例)以及吸烟少组(F组,n=38例),其中,N组、M组和F组依据每周训练时间的长短又都分为运动多和运动少两个亚组,分别为:不吸烟运动少组(NF组,n=28例)、不吸烟运动多组(NM组,n=38例)、吸烟多运动多组(MM组,n=22例)、吸烟多运动少组(MF组,n=23例)、吸烟少运动多组(FM组,n=18例)和吸烟少运动少组(FF组,n=20例)。HRV测试包括时域指标有SDNN、RMSSD、SDSD以及PNN50等,频域指标有TP、HF、LF、HFnu、LFnu、LF/HF以及VLF等。结果:(1)不吸烟时,NM和NF组心率变异性的时域及频域各指标相差不大(P0.05);吸烟相对较少时,FM组的TP、HF和LF等指标的值均大于FF组对应指标的值(P0.05);吸烟相对较多时,MM组的LF/HF值大于MF组的LF/HF值(P0.05)。(2)运动相对较少时,NF组的LF值大于MF组的LF值(P0.05);运动相对较多时,NM组和FM组各时域及频域指标中除LF/HF和LFnu以外的其他各项指标的均值均大于MM组对应各指标的均值,其中,FM组的RMSSD和SDSD等的值与MM组对应两指标值的差异具有显著性意义(P0.05)。结论:(1)吸烟和缺乏规律性的健身活动(每周训练时间少于300min)都是影响心率变异性的风险因素。(2)吸烟指数少于200者,规律性的健身活动(每周总时长超过300min)对于心率变异性存在明显的改善作用。(3)吸烟指数大于200者,规律性的健身活动(每周总时长超过300min)未能干预吸烟对心率变异性形成的不良影响,必须戒烟。(4)运动强度作为影响心率变异性的一个重要因子,建议后续研究运动对于心率变异性影响时应作重点具体化考量。(5)吸烟引起心率变异性的变化是个急性效应,建议后续研究吸烟对于心率变异性的影响可以将每日吸烟支数作为影响因子。
[Abstract]:Objective: to explore the interaction of two potential autonomic nervous function influencing factors, long training and smoking, on heart rate variability (HRV) in healthy young and adult men, in order to improve the autonomic nervous function of young and middle-aged men. Methods: 149 subjects were selected in this study. According to the smoking index, the subjects were divided into two groups: non smoking group (n = 66), smoking group (n = 45) and smoking group (n = 38). And exercise less than two subgroups, The results were as follows: no smoking exercise group, NF group (n = 28), non-smoking exercise group (n = 38), NM group (n = 22), smoking exercise group (n = 23), smoking exercise group (n = 18) and FM group (n = 18). HRV tests included SDNNs, SDS-SDS-SDSD, PNN50, and so on. The frequency-domain indexes include VLF and VLF. Results the time domain and frequency domain indexes of heart rate variability of NM group and NF group were not significantly different from those of NF group when smoking was relatively low, and the values of VLF and LF in FM group were higher than those in FF group when smoking was relatively low. When smoking more frequently, the LF/HF value of MM group was higher than that of MF group. (P0.05) if exercise was less, LF value of NF group was higher than LF value of MF group (P0.05), and the time domain and frequency domain indexes of NM group and FM group except LF/HF and LFnu were higher than those of MF group when exercise was more frequent. The mean value of each index is larger than that of MM group. There was significant difference in RMSSD and SDSD between FM group and MM group (P 0.05). Conclusion smoking and lack of regular exercise (less than 300min per week) are risk factors affecting heart rate variability. Smoking index less than 200, Regular exercise (more than 300 minutes per week) significantly improved heart rate variability. Regular exercise (more than 300 mins a week) failed to interfere with the adverse effects of smoking on heart rate variability, and the intensity of exercise was an important factor affecting heart rate variability. It is suggested that the following study exercise should focus on the specific consideration of heart rate variability. (5) the change of heart rate variability caused by smoking is an acute effect. It is suggested that the influence of smoking on heart rate variability may be influenced by daily smoking number.
