In this study, we will evaluate the impact of the dietary supplement of krill oil concentrate, which contains the omega-3 HUFAs, on the success of U.S. Army officers training outcomes in Infantry Basic Officer Leadership Course (IBOLC) training Part I) and Ranger training (Part II). We are researching the effects on key performance measures from the two parts of their training, as well as underlying psychological and cognitive functioning that are components of success. The questions addressed by this study are:
1. Will treatment with krill oil concentrate containing the omega-3 HUFAs improve cognitive and psychiatric functioning during U.S. Army Infantry Basic Officer Leadership Course (Part I)?
2. Will treatment with krill oil concentrate containing the omega-3 HUFAs improve the performance of officers during portions of the U.S. Army Infantry Basic Officer Leadership Course (Part I) and Ranger training (Part II)? This phase will combine the cognitive and physiological challenges from which we measure performance outcomes.
3. Do effects of the supplements continue once a person stops taking them? Are there any group differences in functioning observed 2 months after treatment is discontinued (i.e., after Ranger training)?
A small sub-study will address the same questions among older, more experienced Army personnel in Part I only.
