目的了解歼击机飞行员抗荷正压呼吸复训时心率的变化,评价其复训效果。方法按照飞行员专项训练大纲的方法,对51名初训和30名复训飞行员进行训练,记录并比较两组的心率、肱动脉收缩压以及用血压值推算出的抗荷耐力。结果①随加压值增大,飞行员心率、收缩压及抗荷耐力均呈递增变化,与基础值相比,其差异性均有显著意义(P<0.01);②按大纲规定的标准,两组飞行员均可达标。两组间收缩压的净增值差异无显著性意义(P>0.05),但复训组心率较初训组心率明显减少(P<0.01)。结论①抗荷正压呼吸训练时,心率与加压值和动脉收缩压密切相关。心率能反映飞行员对抗动作的体能消耗。心率是评价抗荷正压呼吸训练效果的简易指标。②复训飞行员能以较小的心负荷和更多的心贮备对抗相等的加压值,表明抗荷正压呼吸复训效果良好。
Objective To understand the changes of heart rate during fighter pilots’ anti-stress and resuscitation training and evaluate the effect of rehabilitation training. Methods According to the pilot training program, 51 primary training and 30 training pilots were trained. The heart rate, systolic blood pressure of brachial artery and anti-endurance estimated by blood pressure were recorded and compared. Results ① The heart rate, systolic blood pressure and anti-endurance increased with the increase of the pressure value, and the difference was significant compared with the baseline value (P <0.01). ② According to the standard of the outline, Group pilots are up to standard. There was no significant difference in the net value of systolic blood pressure between the two groups (P> 0.05). However, heart rate of the training group was significantly lower than that of the training group (P <0.01). Conclusions ① During anti-stress positive pressure respiration training, the heart rate is closely related to the pressure value and arterial systolic pressure. Heart rate can reflect the physical energy consumption of the pilot’s confrontation. Heart rate is a simple indicator to evaluate the effect of anti-stress positive pressure breathing training. ② training pilot pilots with a smaller heart load and more reserves against the equal pressure value, indicating that positive anti-pressure resuscitation training effect is good.
