What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Subjective mental energy: Cognitive test battery

    Changes in subjective measures of mental alertness and mental fatigue through computer administered cognitive test battery domains of short-term memory, attention and mood. Tasks are word presentation, word recognition, picture presentation, picture recognition, Cognitive Demand Battery (CDB) serial 3 and serial 7 subtraction, and Bakan task/Rapid Visual Information Processing (RVIP). Performance measures: % correct, % errors and response time in milliseconds.

    Measured: Baseline and 60 min post treatment

  2. Subjective mental energy: VAS for mental alertness

    Changes in subjective ratings of mental alertness following computer administered cognitively fatiguing tasks. Visual Analog Scale (VAS) for mental alertness has the score range 0-100 (from not at all to extremely).

    Measured: Baseline and 60 min post treatment

  3. Subjective mental energy: VAS for motivation

    Changes in subjective ratings of motivation following computer administered cognitively fatiguing tasks. Visual Analog Scale (VAS) for motivation has the score range 0-100 (from not at all to extremely).

    Measured: Baseline and 60 min post treatment

  4. Subjective mental energy: VAS for mental fatigue

    Changes in subjective ratings of fatigue following computer administered cognitively fatiguing tasks. Visual Analog Scale (VAS) for fatigue has the score range 0-100 (from not at all to extremely).

    Measured: Baseline and 60 min post treatment

  5. Subjective mental and physical energy: VAS for mental and physical state and trait energy and fatigue (EFS State Scales)

    Changes in subjective ratings of mental alertness, motivation and fatigue following computer administered cognitively fatiguing tasks. Mental and Physical State and Trait Energy and Fatigue Scales (EFS State Scales) consist of 12 VAS items to measure intensity of current feeling of physical energy and fatigue and mental energy and fatigue (3 sub-scales each). Score range: The 3 items from each sub-scale are summed and scores for each sub-scale range from 0-300 (none to strongest).

    Measured: Baseline and 60 min post treatment

  6. Subjective mental energy: VAS for mood

    Changes in subjective ratings of mental alertness, motivation and fatigue following computer administered cognitively fatiguing tasks. The Bond-Lader test uses 16 Visual Analog Scales (VAS) to measure different aspects of mood, with score range 0-100 for each scale (from absence of feeling to presence of feeling).

    Measured: Baseline and 60 min post treatment

  7. Subjective mental energy: VAS for caffeine symptoms

    Changes in subjective ratings of mental alertness, motivation and fatigue following computer administered cognitively fatiguing tasks. Caffeine symptoms are measured on paper using 8 Visual Analog Scales (VAS) with score range 0-100 (from not at all to extremely).

    Measured: Baseline and 60 min post treatment

Secondary outcomes (5)
  1. Physical performance

    Mean power output in a timed cycling trial following post-treatment cognitive test battery and caffeine symptom VAS.

    Measured: During the last 3 minutes of 23 min high intensity cycling exercise (10 x 1 min work intervals each followed by 1 min rest. No rest after final interval, 3 min max power from minutes 20-23.

  2. Physical Fatigue

    Subjective categorical scale, score range 0-7, higher score indicates greater feeling of physical fatigue

    Measured: After each of 10 1-minute high intensity cycling intervals separated by 1 min rest and at end of exercise.

  3. Alertness

    Subjective categorical scale, score range 1-7, higher score indicates greater alertness meaning a greater feeling of energy

    Measured: After each of 10 1-minute high intensity cycling intervals separated by 1 min rest and at end of exercise.

  4. Effort

    Subjective categorical scale, Borg Ratings of Perceived Exertion (RPE) measures perception of effort, score range 6-20. Higher score indicates greater effort. 17 or greater generally indicates maximal effort

    Measured: After each of 10 1-minute high intensity cycling intervals separated by 1 min rest and at end of exercise.

  5. Quadriceps muscle pain

    Subjective categorical scale with ratio-like properties, scale 0-10 with open-ended option for ratings greater than but proportional to 10. Higher scores indicate greater perception of pain in the quadriceps

    Measured: After each of 10 1-minute high intensity cycling intervals separated by 1 min rest and at end of exercise.

Questions about this trial

What is this clinical trial studying?

A study testing Flavored beverage in people with Mental Energy and Physical Performance, run by PepsiCo Global R&D at 1 site in United States.

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 3 inclusion and 14 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 18 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

Subjective mental energy: Cognitive test battery (time frame: Baseline and 60 min post treatment). The study lists 7 primary outcomes in all. 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 18 Jan 2020.
