Conduct after capture (CAC) training effectively induces stress, as measured by elevated cortisol levels in soldiers. This stress response indicates successful stress inoculation, crucial for personnel facing capture scenarios.
Area of Science:
- Military Psychology
- Stress Physiology
- Performance Psychology
Background:
- Conduct after capture (CAC) training aims to prepare personnel for stressful capture situations.
- Effective stress inoculation requires training to be sufficiently stressful.
- Objective measures are needed to validate the stress levels experienced during CAC training.
Purpose of the Study:
- To evaluate the stress levels during CAC training using physiological and cognitive measures.
- To determine if CAC training meets the criteria for effective stress inoculation.
- To assess the impact of different pre-training states on stress response during CAC.
Main Methods:
- Salivary cortisol levels were measured at baseline and during a ~24-hour CAC training course.
- Cognitive performance was assessed before and after the training.
- Participants were divided into three groups based on pre-training conditions: sleep-deprived (Group A), well-rested (Group B), and SERE instructors (Group C).
Main Results:
- Group A showed a significant cortisol increase, multiple times higher than expected baseline values.
- Group B exhibited elevated cortisol levels, which normalized later in the training.
- Group C displayed the least cortisol elevation.
- No significant cognitive performance decline was observed, though some participants froze under stress.
Conclusions:
- CAC training effectively induces significant physiological stress, validating its role in stress inoculation.
- Cortisol level increases confirm that CAC training is sufficiently stressful.
- While cognitive performance did not decline, behavioral freezing indicates extreme stress responses in some individuals.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

The Role of Exercise in Stress Management
Regular physical activity is essential for reducing stress and promoting cardiovascular health. Exercise strengthens the heart, enhances blood flow, keeps blood vessels flexible, and helps lower blood pressure, all of which reduce the body's stress response. Research shows that adults who exercise regularly have nearly half the...
