statistically significant differences on the level *p* < 0.05. part 1, 2, 3, 4—parts of IPAQ; rg—effect size.

There were no statistically significant differences between the surveyed groups of soldiers in the variables "time spent sitting on a weekday" and "time spent sitting on a weekend". It was calculated that the flight crew spends 258 min per weekday and 211 min per weekend sitting (ground staff: 235 min and 219 min, respectively).

In order to determine which variables had the greatest impact on BMI, correlations were calculated and the level of statistical significance was determined. No correlations were found in the group of All Air Force soldiers (Table 4). Taking into account the total number of All flight crew, a statistically very weak negative correlation was found between BMI and total MET, MET work, MET transportation (relocation) and walking. In the group of ground staff only one correlation was found, between BMI and MET work (<30 years).
