Accommodating adolescent sleep-wake patterns: the effects of shifting the timing of sleep on training effectiveness.

Study Objective: This study evaluated the effect of accommodating adolescent sleep-wake patterns by altering the timing of the major sleep period of US Army recruits.

Design: The quasi-experimental study compared recruits assigned to one of two training companies: one with a customary sleep regimen (20:30 to 04:30) while the other employed a phase-delayed sleep regimen (23:00 to 07:00), the latter aligning better with biologically driven sleep-wake patterns of adolescents.

Setting: The study was conducted during Basic Combat Training (BCT) at Fort Leonard Wood, Missouri.

Sleep and fatigue issues in continuous operations: a survey of U.S. Army officers.

Forty-nine U.S. Army officers with recent combat experience were surveyed to assess their units' sleep patterns and to determine the tactics, techniques, and procedures used to counter the effects of sleep deprivation in their units.

Longitudinal study of sleep patterns of United States Military Academy cadets.

Study Objectives: The study provided an opportunity to observe sleep patterns in a college-age population attending the United States Military Academy.

Design: This 4-year longitudinal study investigated sleep patterns of cadets. A stratified sample of 80 cadets had sleep patterns monitored using actigraphy for 8 months: one month in both fall and spring academic semesters over a 4-year period.

Sleep patterns of young men and women enrolled at the United States Military Academy: results from year 1 of a 4-year longitudinal study.

Study Objectives: Sleep patterns of young adults are different from those of other age groups.. This study examined sleep patterns of cadets during their first year at the United States Military Academy.
