'The purpose of this study was to determine the caloric expenditure (CE) and exercise intensity (EI) on FAB F5 fighter pilots during the combat flight. There were 6 male subjects (34.8 ± 3.4 yrs; 73.3 ± 13 kg; 1.8 ± 0.1 m; 23.4 ± 2.6 kg.m-2). All subjects underwent a maximal progressive cycling test to exhaustion. The gas analyzer VO2000 was applied to determine VO2 max. HR max was measured using a heart rate monitor (Polar RS400). HR was monitored during two combat flights. CE was calculated by using regression equations generated from the relationship between VO2 and HR. EI was calculated by the percentage of HR max obtained in the tests; average values: VO2 max (1.9 ± 0.5 L.min-1); HR max (174 ± 14 beats.min-1). The average CE per minute of flight and total CE were 2.9 ± 0.9 kcal and 134 ± 51.7 kcal for flight 1; and 3.1 ± 1.8 kcal and 126 ± 87 kcal for flight 2. EI remained at 56 ± 5.5% of HR max in flight 1 and 60 ± 8% of HR max in flight 2. No significant differences were found in any studied variables during flights 1 and 2. In conclusion, due to the fact that the results presented low CE and slight EI, the fatigue reported by the aviators is not the main factor for the physical wear after this type of flight.
