Abstract:
To analyze the change of physiological indices in male and female pilot students during lower body negative pressure (LBNP) exposure, one female group and one male group participated in the experiment. They were subjected to LBNP up to 50 mmHg for 8 min. Electrocardiogram (ECG), heart rate (HR), blood pressure (BP), cerebral blood flow (CBF) and time of exposure were monitored during LBNP. The results showed that during LBNP, heart rate (HR) increased while systolic blood pressure (SBP) and cerebral blood flow (CBF) decreased with the prolongation of exposure. It is concluded that LBNP exposure could produce similar physiological changes in both male and femal pilot students.
