摘要
目的观察新型冠状病毒(以下简称新冠病毒)感染康复后飞行学员载人离心机训练的抗荷耐力和生理指标变化,探讨新冠病毒感染对飞行学员载人离心机训练是否存在影响,为后续感染康复后飞行人员相关载人离心机训练提供依据。方法选取2022年参与当批载人离心机训练的飞行学员12名,根据是否感染过新冠病毒将其分为康复组和对照组,每组各6名。2组均分别进行载人离心机快增长率(rapid G onset rate,ROR)试验和慢增长率(gradual G onset rate,GOR)试验,同时记录其在试验过程中的心率及呼吸频率变化,收集抗荷耐力情况。结果康复组飞行学员保持松弛状态时的抗荷耐力(GOR耐力1)平均值为(4.2±0.8)G,做抗荷动作时的抗荷耐力(GOR耐力2)平均值为(5.7±0.6)G;对照组飞行学员的GOR耐力1平均值为(3.4±0.3)G,GOR耐力2平均值为(6.0±0.6)G。与对照组相比,康复组飞行学员的GOR耐力1和2的值差异均无统计学意义(P均>0.05)。与对照组相比,载人离心机ROR和GOR试验过程中康复组飞行学员的平均心率和呼吸频率变化差异均无统计学意义(P均>0.05)。结论新冠病毒感染康复后不会影响飞行学员载人离心机训练的表现,也不会影响其使用抗荷动作和心血管调节储备能力。
Objective To explore whether Corona Virus Disease 2019(COVID-19)has any impact on human centrifuge training of flying cadets and to provide references to the human centrifuge training for the recovered flying personnel by comparing the changes of flying cadets′G-tolerance and physiological indicators in human centrifuge training.Methods Twelve flying cadets who underwent the current batch of human centrifuge training in 2022 were selected and divided into rehabilitation group and control group according to whether they had been infected with COVID-19,with 6 in each group.The rapid G onset rate(ROR)and gradual G onset rate(GOR)were respectively chosen for human centrifuge test.At the same time,the changes of their heart rate and respiratory rate during the tests were recorded,and the G-tolerance situations of the subjects were collected.Results The average relaxed G-tolerance under GOR(GOR tolerance 1)was(4.2±0.8)G in rehabilitation group,and their average anti-G straining maneuver aided G-tolerance under GOR(GOR tolerance 2)was(5.7±0.6)G.Compared with that of the control group,there was no significant difference in GOR tolerance 1 and GOR tolerance 2(both P>0.05).There was no significant changes in heart rate and respiratory rate in ROR and GOR human centrifuge tests between 2 groups(all P>0.05).Conclusions COVID-19 didn't impact the recovered flying cadets'performance in human centrifuge training,as well as the anti-G straining maneuver effect and cardiovascular regulation.
