A static model based on eye-heart vertical distance has been developed which predicts group mean G tolerances relative to the application of any of the following anti-G methods and/or physiologic responses: a) anti-G suit, b) reclined seat, c) anti-G straining maneuver (AGSM), d) positive pressure breathing (PPB), e) gradual onset of G, f) isometric muscular contraction, and g) leg elevation. This model was validated with published data. A variation of this model (derived equation) predicts the amount of AGSM (in mm Hg) required, in combination with any of the anti-G methods/responses at any G level. This calculated effort of AGSM can be equated to level of fatigue and performance decrements. A level of 50 mm Hg or an increase of 2 G in the upright seat was the maximum AGSM recommended for routine use as an anti-G method for operational fighter pilots.
基于眼心垂直距离开发了一种静态模型，该模型可预测相对于以下任何一种抗荷方法和/或生理反应应用时的群体平均G耐力：a）抗荷服，b）倾斜座椅，c）抗荷紧张动作（AGSM），d）正压呼吸（PPB），e）G值逐渐增加，f）等长肌肉收缩，g）腿部抬高。该模型已通过已发表的数据进行验证。此模型的一个变体（导出方程）可预测在任何G值水平下，与任何抗荷方法/反应相结合时所需的AGSM量（以毫米汞柱为单位）。这种计算得出的AGSM努力程度可等同于疲劳程度和性能下降情况。对于作战战斗机飞行员作为常规抗荷方法使用，50毫米汞柱的水平或直立座椅中G值增加2G是推荐的最大AGSM值。
