Abstract
Sleep loss has been shown to negatively impact upon a variety of factors influencing human performance, including cognitive functions, affective states, and subjective mood. Recently, attention has centred around sleep behaviour in athletes, with a growing concern focused on optimising sporting performance. Anecdotally, sports performers often report disrupted sleep prior to competition. However, the literature remains scarce in regards to whether athletes' believe their previous night's sleep will have any impact upon their upcoming performance. To address this issue, competitors were surveyed at the Gold Coast Airport Marathon event series regarding their sleep behaviour the night prior to that competition.
