Abstract:
Objective:To explore the quantitative effect of smoking on pilots′ physical fitness.Methods:According to smoking index, 215 fighter pilots were chosen as subjects and divided into non-smoking group (143 cases), low smoking-index group (23 cases), moderate smoking-index group (20 cases) and high smoking-index group (29 cases). Subjects were asked to rest on the power bicycle for 3 min, then start warm up at a speed of 60 r/min (no-load, low-level exercise at 60 r/min) for 3 min, and then execute continuously exercise at a constant speed with a power increase of 25 W/min. The load exercise was stopped immediately when the maximum exercise level was reached. Age and body mass index (BMI) were recorded, and cardiopulmonary function indexes such as exercise time, exercise power and respiratory exchange rate (RER) were measured.Results:There was no significant difference on age, BMI and RER among the 4 groups ( P>0.05), but there were significant differences in exercise time and exercise power ( F=6.02, 6.25, P=0.001, P<0.001). Under the condition of the same RER, the exercise time and exercise power of the moderate and high smoking-index group (472.1±54.6 s, 456.9±60.4 s and 197.2±23.1 W, 190.2±24.4 W) were significantly less than those of the non-smoking group (506.3±65.5 s and 211.1±26.9 W) ( P<0.05). Conclusions:This study showed that the exercise time and exercise power of moderate and high smoking-index pilots in increasing power bicycles were significantly lower than those of non-smoking pilots. If the pilots were with moderate-high smoking index their cardiopulmonary function would be affected.
