0231 Sleep Behaviors of Female Collegiate Athletes

Abstract Introduction Sleep is critical to cognitive and physiologic function. It is likely being a female collegiate student athlete places unique demands upon sleep behavior. Therefore, we aimed to study the sleep behavior of female collegiate athletes versus a female collegiate control group. Methods Full time female students from the University of Colorado Boulder (Altitude = 1,624 m) were recruited from NCAA Division I athletic teams: Cross Country (XC, n=10), Lacrosse (LAX, n =17), Soccer (SOC, n=15), Golf (GOLF, n=6), Tennis (TENN, n=9). 31 female full-time students were recruited as Controls (CONT). Sleep was monitored with wrist actigraphy (Spectrum Actiwatch, Phillips) for a minimum of one week. Subjects were instructed to wear actigraphs at all times except during competition. Outcome variables included nightly sleep duration, total 24h sleep duration, sleep efficiency, sleep midpoint, social jet lag (SJL) and nap duration/frequency. Results On weekdays, XC, LAX and SOC had greater nightly sleep durations ~8.5h compared to TENN, GOLF and CONT (p
