Identifying non-pharmacological means of enhancing sleep is an important area of research for elite athletes. Research completed at the AIS has identified that some athletes have difficulties falling and staying asleep during both training and competition.
There are a number of dietary components such as nutrients and certain dietary supplements that are purported to decrease sleep latency and increase quality of sleep. While many of these interventions have been investigated in isolation, no research has examined different combinations and/or amounts of these substances to determine the resultant effects on sleep. The results of such a systematic investigation could produce an effective diet based sleep product ("Sleep Drink').
The optimal components, amounts, and timing of intake of such a Sleep Drink will be explored. Additionally, the effects on sleep will be evaluated using the gold standard of sleep measurement: polysomnography.
Exclusion Criteria:
Proprietary blend of nutritional interventions aimed at increasing sleepiness
Other: Tryptophan
Beverage including tryptophan
polysomnography
The effect of the drinks will be determined primarily by polysomnography
Time frame: 0-3 hours
