目的:探讨低氧适应的量化指标,改进飞行员航空生理低氧训练方法。方法:以模拟3.5km高空低氧环境吸入前1天为训练前,连续低氧吸入15天后的次日为训练后,于低氧训练前、后分别记录受训者在模拟7.5km高空环境下脑电图α节律能量状态。结果:急性低氧训练前,模拟7.5km低氧环境下每个时段脑电α节律能量升高明显强于急性低氧训练后每个时段。结论:经过模拟3.5km高空低氧训练15天后大脑抵御缺氧环境的能力明显提高,产生了低氧适应;模拟7.5km高空环境下脑电α节律能量可作为测定大脑低氧适应的量化指标。航空生理训练中的低氧耐力训练建议增加低氧适应性训练。
Objective: To explore the quantitative indicators of hypoxia adaptation and to improve aerobics aerobics training methods. Methods: One day before hypoxia in 3.5km altitude before training and the other day after continuous hypoxia inhalation for 15 days were taken as training days. Before and after hypoxia training, trainees were recorded respectively under simulated 7.5km altitude environment Electron alpha rhythm energy status. Results: Before acute hypoxia training, the rhythmic EEG energy of each time period under simulated hypoxic environment of 7.5km was significantly higher than that of acute hypoxic training. CONCLUSION: After simulating 3.5km altitude hypoxia training for 15 days, the ability of the brain to resist hypoxia is significantly increased and hypoxia adaptation is produced. Simulating the rhythmic energy of cerebral EEG at 7.5km altitude can be used as a quantitative indicator of cerebral hypoxia adaptation. Hypoxic training in aerobics training suggests increasing hypoxic adaptation training.
