Acute Recovery of Physiological and Cognitive Function in U.S. Army Ranger Students in a Multistressor Field Environment

Abstract

The time course for soldier recovery and reentry to the battlefield following high intensity direct action missions is of importance to unit commanders and military planners. It also provides a critical background understanding for medical researchers investigating approaches to extend the limits of soldier physical and psychological endurance. This report summarizes findings for soldiers followed through two recovery periods, during and after, a prolonged exhaustive military activity, the U.S. Army Ranger course. Within the course, with a modest increase in sleep and energy intake for 7 days, the soldiers demonstrated recovery of some cognitive function (e.g., decoding and pattern analysis) and acute metabolic/stress markers (e.g., serum testosterone, IGF1, and triiodothyronine).
