Figures & data

Figure 1. Study procedure including data and hormone sampling during officer training, TSST-G and field exercise.

Table 1. Study characteristics.

	N	M(SD)/n
Demographics
Age (years)	67	20.46 (1.33)
BMI (kg/m^2)	67	23.58 (2.50)
Height (cm)	67	178.43 (6.48)
Weight (kg)	67	75.14 (9.44)
Smoker/nonsmoker	67	10 / 57
Education (upper secondary level/tertiary level)	67	66 / 1
Stressor characteristics
Duration of TSST-G (min)	67	20
Duration of military field exercise (tunnel in min)	63	44.42 (11.50)
Duration of military field exercise (total in min)	63	121.75 (31.48)

Note. The total duration of the military field exercise shows the average duration in minutes in the field including preparation, infiltration, and tunnel, whereas the duration of the single stressor in the tunnel shows only this time.
