Objective To provide references for further assessment of fighter pilots'physical status by comparing and analyzing the difference of cardiopulmonary reserve function between different performance fighter aircraft pilots.Methods A total of 96 fighter pilots were selected in the annual physical examination of the Air Service Department of Northern Theater Air Force Hospital.They were divided into the high-performance fighter group and the ordinary fighter group according to the aircraft types.Cardiopulmonary exercise testing(CPET)was performed to compare the basic parameters and cardiopulmonary reserve function parameters such as peak equivalent,peak oxygen pulse and peak kilogram oxygen uptake in the CPET monitoring results of the 2 groups.Results There was no significant difference in general information between the 2 groups(all P>0.05).There was no significant difference between the high-performance fighter pilots and the ordinary fighter pilots in the main exercise cardiopulmonary reserve function parameters such as peak exercise load,peak oxygen pulse and peak kilogram oxygen uptake(all P>0.05).Conclusions The general performance of the ordinary fighter pilots is the same as that of the high-performance fighter pilots in terms of exercise cardiopulmonary reserve function,and the CPET results can also reflect the status of pilot's physical training.
