目的：研究间歇性低氧训练（IHT），以及训练结束后的运动性疲劳与恢复过程对H反射各参数的影响。方法：用自制低氧混合气体，对8名短跑运动员进行每日10～11％02的循环低氧刺激，持续两周，在IHT前后以及IHT之后的疲劳与恢复过程进行H反射各参数测试。结果：两周IHT训练前后M波振幅增加，H波潜伏期升高，差异具有显著性；疲劳后即刻H波振幅下降，恢复期前三分钟H波振幅显著降低，随后逐渐恢复，在恢复期第15分钟，H波振幅显著升高。结论：H反射是敏感的反映低氧训练以及疲劳对短跑运动员神经系统的影响指标，并提示H反射低氧训练的改变以及运动性疲劳前后以及恢复期的变化与两周低氧训练引起的H反射通路脊髓水平的适应性有关。

Objective： Study the effects of intermittent hypoxic training（ IHT）, muscle fatigue and its recovery process on the H--refle. Methods： We made Two weeks of IHT Training on eight sprint athletes by inspiring 10-11%O2 self--made hypoxic gas mixture The parameters of H-- reflex were recorded pre and post IHT and also during the recovery process of muscle fatigue. Result： Amplitude of M wave increased but the latency of H wave increased pre and post IHT training significantly. There was noticeable decrease during the first three minutes of recovery process and it recovered gradually after this. But it increased significantly at the fifteenth minutes during the recovery process. Conclusion： H--reflex is a sensitive index to the effects of sports fatigue and intermittent hypoxic training on the nervous system of sprint athletes. There might be some changes of H reflex due to the adaptability of the H reflex pathway in spinal cord.
