Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 40 years
  • Men only
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • 18-40 year old males

Who cannot join

  • Exclusion: Exclusion criteria will include any observed or disclosed injury, illness, sleep or health issue which may disrupt the subject's performance or endanger their health. Participants will need to complete an adult screening tool, as recommended by Exercise and Sports Science Australia (ESSA), to assess this.
  • Blood samples will also be collected to screen for magnesium, zinc and B12 which may influence nutritional impact on sleep. If subjects score above the reference ranges for these measures, they will be excluded.
  • The Pittsburg Sleep Quality Index (PSQI) and Stanford Sleepiness Scale (SSS) will be used to screen for sleep disturbances. If subjects score outside the reference ranges for these questionnaires, they will be excluded.

About this study

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.

Questions about this trial

What is this clinical trial studying?

A study testing Tryptophan in people with Sleepiness in Athletes, run by PepsiCo Global R&D.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

polysomnography (time frame: 0-3 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Sep 2018.
