为探究高原低氧低压环境对运动员自主神经引起的变化,提供更多准确的监测方法和指标,对10名女子速滑运动员在高原训练前后的心率变异性指标进行分析。结果:在1800m高原进行陆地训练3周后,与高原训练前指标相比,速滑运动员的、TP指标上升,LF、LF/HF指标下降,但不具有显著性差异,庞加莱图出现收缩趋势。结论:女子速滑运动员在高原环境中,自主神经未受到明显波动,高原训练风险较低。 In order to explore the change of autonomic nervous system of athletes caused by low altitude hypoxia environment and provide more accurate monitoring methods and indexes, the indexes of heart rate variability of 10 female skaters before and after altitude training were analyzed. Results: Compared with the pre-plateau training indicators, the TP index, the LF, LF / HF index of the skaters were decreased after 3-week training on the 1800m plateau, but there was no significant difference trend. Conclusion: In the plateau environment, the autonomic nervous system of women skaters did not fluctuate significantly and the risk of plateau training was low.
