A series of experiments involving the Qigong (Q-G) maneuver were conducted after our preliminary studies in 1986. Eighteen active fighter pilots served as subjects. After mastery of the Q-G maneuver in 5-7 sessions of training, tests at +1 Gz further verified that the blood pressure raising effect of this maneuver has the characteristics of rapid rising, minimal fluctuation and being readily maintained. The 18 subjects then underwent centrifuge tests. The tolerance to Rapid Onset Rate (ROR) (1 G/s) G-load in a relaxed, unprotected condition was 3.82 G on average; performing the Q-G maneuver, the tolerance rose to 6.64 G, an improvement of 2.82 G. One to two days later, 5 subjects with anti-G suits on and performing the Q-G maneuver tolerated 7.80 G on average (ROR 1 G/s), a gain of 3.95 G. Another 9 subjects performing the Q-G maneuver endured high sustained G (HSG) (ROR 3 G/s) of 6.5 G for 74.4 s on average (max 96 s) and 3 subjects endured HSG of 7.0 G for 57 s on average (max 82 s). During centrifuge tests, recorded physiological values showed good tolerance of the subjects; the respiratory pattern was basically different from that of M-1 or L-1 maneuvers. In further testing the harmlessness of the Q-G maneuver, gas metabolism, ear lobe oximetry and 8-channel EEG were carried out on these subjects. All these indices plus close monitoring during centrifuge tests proved that the Q-G maneuver does not lead to hypoxia or hyperventilation. It has been shown that the Q-G maneuver is an innovative G-protective maneuver that is remarkably effective, theoretically interesting, reliable, and practical. Its mechanism warrants investigation.
在我们1986年的初步研究之后，进行了一系列涉及气功（Q-G）动作的实验。18名现役战斗机飞行员作为受试者。在经过5至7次训练课程掌握Q-G动作后，在+1 Gz条件下的测试进一步证实，该动作的血压升高效应具有上升迅速、波动极小且易于维持的特点。然后这18名受试者进行了离心机测试。在放松、无防护的状态下，对快速启动率（ROR）（1 G/s）G负荷的耐受性平均为3.82 G；执行Q-G动作时，耐受性提高到6.64 G，提高了2.82 G。一到两天后，5名穿着抗荷服并执行Q-G动作的受试者平均耐受7.80 G（ROR 1 G/s），增加了3.95 G。另外9名执行Q-G动作的受试者平均承受6.5 G的高持续G（HSG）（ROR 3 G/s）达74.4秒（最长96秒），3名受试者平均承受7.0 G的HSG达57秒（最长82秒）。在离心机测试期间，记录的生理值显示受试者耐受性良好；呼吸模式与M-1或L-1动作基本不同。在进一步测试Q-G动作的无害性时，对这些受试者进行了气体代谢、耳垂血氧饱和度测定和8通道脑电图检查。所有这些指标以及离心机测试期间的密切监测证明，Q-G动作不会导致缺氧或过度通气。已经表明，Q-G动作是一种创新的G防护动作，非常有效、理论上有趣、可靠且实用。其机制值得研究。
