Abstract

目的: 探讨共振呼吸调节对运动员认知任务表现的提升作用。方法: 将30名射击运动员随机分为试验组(n=15)和对照组(n=15)。试验组运动员进行每次30~40 min、每周5 d,共计4周的心率变异性生物反馈训练(HRV训练),掌握共振呼吸调节方法,以相同频次进行呼吸调节(每分钟6次);试验采用试验组、对照组前后测的设计,利用第三版神经行为测试评价系统(NES-C3)、生理相干和自主平衡系统SPCS采集运动员的选择反应时和心率变异性(HRV)数据;正式检测,首先让所有运动员经历安静阶段并进行选择反应时测试,随后试验组运动员进行共振呼吸调节,而对照组运动员休息,最后所有运动员再次进行选择反应时测试,测量运动员的心率变异性。结果: 与安静阶段相比,试验组运动员心率(HR)显著下降(P<0.05),心脏总功率(TP)和低频功率(LF)与安静阶段相比显著增加(P<0.01),低频/高频功率(LF/HF)也显著增加(P<0.05),自我调节后的选择反应时显著降低(P<0.05);而对照组无显著变化(P>0.05)。结论: 共振呼吸调节法可以显著增强运动员的心率变异性水平,进行调节后反应时间明显缩短。.
