| 摘 要： | 目的:了解高原地区中长跑运动员心率变异性特征。方法:云南师范大学男子中长跑运动员12名,设为实验组,普通大学生12名,设为对照组。对两组安静状态下10 min短时心率变异性进行时域、频域及非线性分析。结果:实验组时域各项指标平均RR、RMSSD、pNN50、SDNN/HR均显著高于对照组(P0.05,P0.01)。频域各指标中HFn.u.显著高于对照组(P0.05),而LFn.u.显著低于对照组(P0.05),最终LF/HF比值极显著低于对照组(P0.01)。结论:和高原地区普通大学生相比,中长跑运动员具有较高的心率变异性和较大的自主神经调节能力,且与平原地区相应人群无明显差异。

| Abstract: | Objective: To investigate the characteristics of the heart rate variability(HRV) in middle-distance race athletes at plateau.Method: 12 male middle-distance race athletes(test group) and 12 health untrained people(control group) were tested by time domain,frequency domain and nonlinear analysis of 10min HRV.They are from Yunnan Normal University.Result: By time domain method,the RR,RMSSD,pNN50,SDNN/HR in the athletes were significantly higher than control group(P<0.05,P<0.01).By frequency domain method,the HFn.u was statistically higher(P<0.05),LFn.u.was statistically lower,so LF/HF was lower than control group statistically(P<0.01).Conclusion: Compared with the health untrained students,middle-distance race athletes have the higher HRV and ability of regulating autonomic nerve system,and there was no evident difference with objects from plain area. |
