不同海拔高度对学生心率变异性的影响

采用时域分析法、频域分析法对世居高原、亚高原、平原的90名高校非体育专业农村男学生进行心率变异性测试。结果表明:机体的交感神经调节功能随着海拔高度的增高呈现出先增强再降低的趋势;机体的副交感神经调节功能随着海拔高度的增高呈现出先降低再增高的趋势;机体自主神经的总体调节功能呈现出随着海拔高度增加而下降的趋势。

The students in different altitude on HRV

This study aims to make comparative analysis on the charactrisitcs of the regulation function of ANS on different altitudes,by running heart rate variability test on 90 non-PE major students who all come from rural area of the plateau,the sub-plateau,and plains by time domain and frequency domain analysis.The results found that the regulation of sympathetic nerve function showing a trend of first increasing and then decreasing as the altitude increases;The parasympathetic nerve regulation function declined firstly and then increased;as the altitude increased The autonomic overall adjustment function appears as the altitude increases with decreasing trend.
