【摘要】：目的 :观察经人力短臂离心机锻炼后心率变异性(HRV)参数的变化 .方法 :选取 8名健康男性志愿者进行了连续 7d的人力离心机锻炼 ,每天锻炼时间为 2 0min ,分别于锻炼前、锻炼 3次和 7次后 ,各记录静息心电一次 ,每次记录的时间为 2 0min ,然后利用计算机分析得到HRV的各项指标 .结果 :与锻炼前相比 ,锻炼 3次和 7次后受试者心电的HRV高频成分 (HF)能量显著增加 (P 0 .0 5 ) ,低频成分 (LF)能量显著降低 (P 0 .0 5 ) ,低频成分与高频成分之比 (LF/HF)显著降低 (P 0 .0 5 ) .结论 :通过对心率变异性指标的分析 ,证明人力短臂离心机锻炼可明显改善心血管系统的调节能力 ,增强心脏的泵血功能 .
[Abstract]:Objective: to observe the changes of HRV parameters after human short arm centrifuge exercise. Methods: eight healthy male volunteers were selected for 7 consecutive days of human centrifuge exercise. The daily exercise time was 2 0min. Before exercise, 3 times and 7 times respectively, resting ECG was recorded. The time of recording was 2 0min, and then the indexes of HRV were obtained by computer analysis. Results: compared with before exercise, three and seven times of exercise significantly increased the energy of high frequency components of HRV (P 0.05), and decreased the energy of low frequency components (P 0.05). The ratio of low frequency component to high frequency component was significantly lower than that of low frequency component (P 0. 05). Conclusion: by analyzing the indexes of heart rate variability, it is proved that human short arm centrifuge exercise can obviously improve the regulating ability of cardiovascular system and enhance the pumping function of the heart.
