Most Warfighters are familiar with the sleep, activity, and nutrition tenets of Performance Triad, but may not be as familiar with what the scientific evidence says about how these recommendations impact Warfighter readiness, health, and overall well-being. The Science Behind Performance Triad effort aims to present the individual research studies that support and inform P3 recommendations, to ensure a fit and ready Force. The ultimate goal of these studies is to improve awareness and understanding of the science behind Performance Triad. Each study will be explained in easy-to-understand terms, including discussion of why and how the study was performed, description of study results, and explanation of how the study results translate to benefitting Warfighters.
