**5. Conclusions**

In general, the Air Force soldiers represented a high and moderate level of physical activity. However, every fifteenth respondent revealed a low level of physical activity. There were no differences in the level of physical activity between flight crew and ground staff. Moreover, the BMI of the examined soldiers indicated overweight tendencies, and a comparative analysis with the results of research from many years ago revealed that the largest increase in BMI occurred in the group of soldiers aged 19 to 30. In the Air Force, educational programs on health promotion specific to the Air Force and individual military specialties should be introduced. Preventive programs to date have not contributed to an increase in care regarding the correct level of body weight, and to an increase in level of awareness regarding the positive aspects of physical activity. The above statements were particularly strongly confirmed by the results of research on soldiers of the younges<sup>t</sup> age (up to the age of 30). It is therefore all the more necessary to undertake immediate educational interventions.
