为了比较两种气功对模拟失重的对抗能力，观察了７７名男性青年被试者。其中１０名为未练过任何气功的对照组；１７名为大专气功二年级学生，修练动功１年多为气功１组。５０名相当于大专的气功师资班学生练的是智能气功，为气功Ⅱ组。以受试者头低位（─３０°）３０ｍｉｎ作为模拟失重的急性刺激，观察心搏量、下肢血流、血压、心率、膻中和劳宫穴的皮肤温度变化。结果表明，在头低位（─３０°）的刺激下，气功组的下肢血流增加，明显高于对照组，且具有统计学意义。而气功Ⅱ组又好于气功Ⅰ组。对照组的舒张血压升高，达１４％，而气功Ⅰ组只增加４％，气功Ⅱ组则未有增减。同时，气功组的膻中、劳宫穴皮肤温度也明显高于对照组。证明，气功组与对照组相比，有较高的对抗模拟失重能力。两组气功组相比，则气功Ⅱ组对模拟失重有更好的对抗能力。
In order to compare the resistance of two Qigongs to simulated weightlessness, 77 young male subjects were observed. Among them, 10 were control subjects who had not practiced any Qigong. 17 were second-year students of the Qigong College and more than one year practiced their Qigong practice in the Qigong 1 group. Fifty students equivalent to the Qigong teachers in the junior college practice qi gong and Qigong group Ⅱ. The subjects were low (─30 °) 30min as a simulated weightlessness acute stimulation, observation of stroke volume, lower limb blood flow, blood pressure, heart rate, Langzhong and Laogong acupuncture skin temperature changes. The results showed that in the head low (─30 °) stimulation, lower limb blood flow Qigong group increased significantly higher than the control group, and with statistical significance. The Qigong group Ⅱ was better than Qigong group Ⅰ. In the control group, diastolic blood pressure increased by 14%, while qigong group I only increased by 4% and qigong group Ⅱ did not increase or decrease. At the same time, Qiongzhong of Qigong group, the skin temperature of Laogong was also significantly higher than that of the control group. Proved, Qigong group compared with the control group, have a higher ability to fight simulated weightlessness. Compared with the Qigong group, the Qigong group Ⅱ has a better ability to resist simulated weight loss.
