Special Forces Police are called to the most dangerous situations that require skills and equipment beyond the training available to a patrol officer. We recruited a platoon of special forces (n = 18) and examined their basal and reactivity levels of cortisol in relation to occupational duties. Moreover, we measured the impact of a multiday program of intensive resilience and tactical training in improving cortisol responses to stressful situations. Participants were significantly more likely to exhibit basal cortisol levels higher than the civilian norms across all of the 5 days of intensive training. However, anticipatory cortisol, measured directly before exposure to critical incident scenarios, was significantly lower in Day 5 than in Day 1 of the training period. This study demonstrates that measuring cortisol is an objective method of examining training effects and possible long-term occupational health outcomes.
