This study deals with the physiologic responses to stress in F-4 fighter pilots and aircrew engaged in surface attack training (SAT) missions. Blood levels of HDL-cholesterol, LDH and LDH isoenzymes, CPK, and myoglobin were determined before and after each mission. Continuous EKG and transcutaneous PO2 recordings were made during briefing, preflight, and inflight. The personal history and habits of each participant were recorded. Each mission consisted of six successive bomb deliveries at 80-s intervals and at increasingly steep dive angles, each terminating in 5.5-6 +Gz during pull-up. Results revealed no apparent effect on HDL, COP isoenzymes, and LDH isoenzymes. Many myoglobin levels dropped as much as 50%. EKG recordings revealed ST elevations, ST depressions, T wave inversions, and marked sinus arrhythmias in some, while others showed increases in cardiac rate. Pilots flying these SAT missions in F-4C aircraft were found not to be significantly physiologically stressed.
本研究探讨了F - 4战斗机飞行员和参与地面攻击训练（SAT）任务的机组人员对应激的生理反应。在每次任务前后测定血液中高密度脂蛋白胆固醇、乳酸脱氢酶（LDH）及其同工酶、肌酸磷酸激酶（CPK）和肌红蛋白的水平。在任务简报、飞行前和飞行过程中进行连续心电图和经皮血氧分压记录。记录了每位参与者的个人病史和习惯。每次任务包括以80秒的间隔、以越来越陡的俯冲角度连续进行六次投弹，每次在拉起过程中以5.5 - 6 +Gz结束。结果显示对高密度脂蛋白、CPK同工酶和LDH同工酶没有明显影响。许多人的肌红蛋白水平下降了多达50%。心电图记录显示，一些人出现ST段抬高、ST段压低、T波倒置和明显的窦性心律失常，而另一些人则心率增加。研究发现，驾驶F - 4C飞机执行这些SAT任务的飞行员在生理上没有受到明显的应激。
