| 摘要： | This project was comprised of two studies-a field study using wrist actigraphy to determine sleep duration and timing in long-versus short-haul CMV drivers over 20 consecutive days; and a sleep/dose/response (SDR) laboratory study on CMV drivers to determine the effects of 3, 5, 7, and 9 hours time in bed (TIB) on performance (included simulated driving) over seven consecutive days. Findings from the latter (SDR) study were used to optimize the parameters of the Walter Reed Sleep Performance Model (SPM)-a mathematical algorithm to predict performance based on prior sleep and circadian rhythm. The SPM has been integrated into the current version of the Sleep Watch Actigraph, a wrist-worn device for management of sleep and performance in the operational environment. In Chapter 1, theoretical background on the nature of sleep loss-induced performance decrements is presented. Chapter 2 provides the methodology used in the SDR (laboratory) study, and the detailed results of that study. Chapter 3 provides the background for SPM development, and a detailed description of the SPM. Chapter 4 presents the methodology used in the field study, and the detailed results of that study. Chapter 5 provides an overview and synthesis of results, conclusions, and recommendations. |
