Utility helicopter pilots have more prevalent and more severe back pain than pilots of other platforms. Yet, it is difficult to make a clear association between type of aircraft and the region of back pain.
This study examined the effects of strength, aerobic fitness, and activity profile on the incidence of overuse injuries, particularly stress fractures, during military training. A total of 136 military recruits were followed during 9 weeks of basic training. Maximal strength and aerobic fitness were determined by a one-repetition maximum leg press and a 2,000-m run, respectively. An activity profile was determined by the recruit's activity history. Twelve recruits (8.8%) were diagnosed with stress fractures. Recruits who were 1 SD below the population mean in both absolute (98.4 ± 36.6 kg) and relative strength (1.72 ± 0.61 kglkg of body weight) had a five times greater risk for stress fracture (p < 0.05) than stronger recruits. Poor aerobic fitness did not appear to be related to any increased incidence of stress fracture. It appears that recruits with lower body strength levels, within 1 SD of the population mean, have a reduced incidence of stress fractures during military training.
The purpose of this study was to evaluate the dietary intake of pilots in the Israeli Air Force and to determine whether reported consumption met the Military Dietary Reference Intakes. Thirty-one pilots completed a 24-hour dietary recall and physical activity questionnaire. Blood parameter values were collected from medical records. Results showed that energy-adjusted sample mean intakes of nutrients met the military recommendations with the exceptions of dietary fiber (53% of the recommended level) and calcium (84% of the recommended level). Macronutrient distribution of energy was 17% from protein, 47% from carbohydrate, and 36% from fat. Although saturated fat consumption was not more than 10% of energy, cholesterol consumption was well above the 300 mg/d presently recommended. For all pilots, blood parameter values were in the normal range. Overall, the diet of Israeli pilots was found to be well balanced, but negative dietary patterns (i.e., high cholesterol intake and low fiber intake) characteristic of the general population were observed in this group.
Overall, at 11 flights (11%) aircrew completed their flight with a meaningful fluid loss. We conclude that military flights may be associated with significant amount of fluid loss among aircrew.Levkovsky A, Abot-Barkan S, Chapnik L, Doron O, Levy Y, Heled Y, Gordon B.
