Many elite athletes have suboptimal sleep duration and efficiency, potentially due to factors that may impact sleep onset and onset times. Variability in sleep onset and onset may negatively influence sleep. The sleep regularity index (SRI) is a novel metric for sleep regularity, however there are no published descriptions of SRI in elite athletes. Further, contributors to sleep efficiency and duration in elite athletes using objective measures have not been explored.
Bedtime and a consistent sleep onset time are important factors associated with sleep efficiency in athletes, while sleep onset is an important factor for total sleep time. Coaches and staff can assist their athletes by providing training schedules that allow for both regularity and sufficiency of time in bed where possible.
