Abstract： Objective We aimed to investigate the lung function level of cadet candidates, and provide basic data for pilot selection. Methods The lung function data of 169 cadet candidates from June 11th, 2011 to July 1st, 2011 were analyzed. Determination of indicators included:lungcapacity and pulmonary ventilation airways function.Results ①Among of the 169 pilot candidates, lung function of 92 candidates was absolutely normal, accounting for 57.40% of the total(92/169).Lung volume of 72 candidates was abnormal, among whom VT and IRV were the mostly abnormal. VT<500ML contained 17 cases, accounting for abnormal lung function by 23.61%(17/72); IRV<2100ml contained 17 cases, accounting for abnormal lung function by 23.61%(17/72); ERV <900ml contained 2 cases, accounting for abnormal lung function by2.78%(2/72) ; both IRV and IC were abnormal at the same time containing 10 cases, accounting for abnormal lung function by 13.89%(10/72). VT, IRV and IC were abnormal at the same time containing 6 cases, accounting for abnormal lung function by 8.33%(6/72).VC was within the normal range accounting for abnormal lung capacity by all of pilot candidates. ②Both large and small function airway decreased containing 8 cases. The incidence of pulmonary function abnormalities was 11.11%, significantly lower than the abnormal lung capacity test (P<0.05).③Decrease of small airway function (MMEF, FEF50%, FEF75% and all of them were<70% of the prediction value of standard) contained 9 cases, accounting for 12.50% of the abnormal lung function. ④Both lung volume and pulmonary ventilation function were abnormal. Total abnormal pulmonary function 3.17% Incidence rate was significantly lower than that of pure decreased lung capacity. Conclusions ①Although chest x-ray and physical examination of the pilot candidates were normal, 42.60% of those people's lung function test results were abnormal. It might be speculated that the contemporary students of high school might lack physical training and momentum. By the lung function test, the kind and nature of the abnormal lung function test among those pilot candidates could be understood in details. ②In the recruitment work, the respiratory system disease history of pilot candidates should be carefully asked. The lung function test not only could provide the basis data for the pilot selection, but also give a target exercise prescriptions to those groups basis on the lung function test, and supply the different training types and training intensity to the different people.
