针对长期从事冰壶训练的专业冰壶运动员,采用实验对比方法,探讨长期冰壶训练对运动员心率变异性的影响效果及机制,进而探讨冰壶运动员技术能力提高与心率变异性变化之间的关系。为完善冰壶训练提供实验依据。将10名普通青年与10名从事专业冰壶训练5年以上的运动员进行心率变异性对照研究。观察运动员从事专业冰壶训练后安静状态下心率变异性(HRV)的变化,其具体分析包括:高频(HF),代表迷走神经活性;低频(LF),代表交感神经活性;低频/高频(LF/HF),代表交感迷走神经平衡。结果显示在安静状态下,冰壶运动员高频(HF)即迷走神经活性明显高于普通人,而低频(LF)即交感神经活性明显低于普通人,低频/高频(LF/HF)明显低于普通人,其机制可能是长期冰壶训练改善了自主神经功能,提高了迷走神经活性而降低了交感神经的活性。
In order to discuss the effect and mechanism of long-term curling training on the heart rate variability of the athletes, aiming at the professional curling athletes who have long been engaged in the training of curling, the relationship between the curling athletes’technical ability improvement and the heart rate variability . Provide experimental basis for improving curling training. Heart rate variability (HRV) control study was conducted on 10 ordinary youths and 10 athletes trained in professional curling for more than 5 years. The changes of heart rate variability (HRV) in the quiet state after professional curling training were observed. The specific analysis included: high frequency (HF), representing vagal activity, low frequency (LF), representing sympathetic activity, low frequency / high frequency LF / HF), representing sympathetic vagal balance. The results showed that under quiet condition, high-frequency (HF) curling athletes showed significantly higher vagal activity compared with ordinary people, while low-frequency (LF) sympathetic activity was significantly lower than that of ordinary people and LF / HF was significantly lower In ordinary people, the mechanism may be that long-term curling training improves autonomic function, increases vagal activity and reduces sympathetic activity.
