Abstract: The effects of training time on sleep has been previously studied; however, the influence on sleep in female collegiate cross-country runners is unknown. The aim of this study was to investigate the influence of training time on self-reported sleep metrics. Eleven female collegiate cross-country runners (mean [M] age?=?19 years, standard deviation [SD] age?=?1 year; M [SD] body mass?=?58.8 [9.6] kg; M [SD] height?=?168.4 [7.7] cm; M [SD] VO2max?=?53.6?[5.6] mL·kg-1·min-1) competing in the 2016 NCAA cross-country season were included in this study. Participants completed a sleep diary daily to assess perceived measures of sleep on days when training took place between the hours of 5:00–8:00 a.m. (AM), and when training did not take place during this time (NAM). Sleep quality questions utilized a 5-point Likert scale, in which a score of 1 is associated with the worst outcomes and a score of 5 is associated with the best outcomes. Sleep duration was significantly higher on NAM (M [SD]?=?8.26 [1.43] h) compared to AM (M?[SD]?=?7.97 [1.09] h, p?
