Abstract：Objective We aimed to observe the cardiovascular characteristics of 16 battle plane pilots under the effect of+4 Gz impact and assess the training method of hyper-gravity tolerance. Methods 16 male battle plane pilots did+Gz tolerance test by an automatic centrifuge. Their physiological indexes including heart rate (HR), blood pressure (BP), stroke volume (SV),cardiac output (CO), total peripheral resistance (TPR) and pulse wave(PW) et al were recorded simultaneously during the training. Results Compared with that of pre-test, significant elevation appeared on HR, BP, SV and TPR with the exception of CO (P<0.01). There were two types of changing HR during platform period. The tendency of Saturation O2 showed obvious decline which arrived at the minimum during the descending period. The amplitude of PW showed the decrease in general in two different types. There appeared significant difference in the changes of BP in the two types. Conclusion Human physiological indexes changed significantly under the effect of+4 Gz, which reflected various cardiovascular responding characteristics. The present research is useful for astronaut selection and medical support.
