Does a 30-day cold weather, high-altitude field training exercise affect mood states in male Marines?
Rigorous military training in challenging environments can cause enduring negative mood states that approach clinical significance up to 90 days post-training.
Bardwell et al. (2005) conducted an observational in Military personnel (n=60). 30-day, cold weather, high-altitude field training exercise vs. Baseline was evaluated on Profile of Mood States (POMS) scores. A 30-day cold weather, high-altitude field training exercise resulted in significant increases in negative mood scores among 60 male Marines that endured up to 90 days post-training.
