  Purpose

Adenosine-triphosphate (ATP) serves as the sole energy source for muscle contraction. Therefore human performance of brief maximal exercise is limited, in part, by the availability of ATP to the contracting muscle. Because muscle ATP storage is small (enough to sustain maximal exercise for less than 1 second), factors that enhance either storage or resynthesis of ATP may have a positive impact on repeated muscle contractions. The current study will test the hypothesis that increasing ATP availability to muscle via oral supplementation will improve performance of repeated high intensity exercise as measured by a) work performed in each of the three 50 contraction fatigue tests, b) sum of total work performed, and c) percentage decrement in total work from the first to third third 50 contraction test.

Primary Outcome Measures:
  • Work Performed [ Time Frame: Measured after 15 days of intervention ] [ Designated as safety issue: No ]
    The work and total work performed in 3 exercise fatigue tests given after 15 days of nutritional intervention.


Secondary Outcome Measures:
  • Decrease in work performed in each successive test [ Time Frame: Measured after 15 days of intervention ] [ Designated as safety issue: No ]
    The decrease in total work performed in each of 3 successive fatigue tests will be measured and used as a measure of muscle fatigability after 15 days of nutritional intervention

Arms Assigned Interventions
Placebo Comparator: Placebo
Oral placebo capsules similar in color and size to the intervention
Dietary Supplement: Placebo
Placebo capsules that are comparable in size and color to the active comparator for blinding purposes
Active Comparator: PeakATP 250
Oral supplement capsules containing 250 mg/day of PeakATP
Dietary Supplement: PeakATP 250
The nutritional intervention provides for oral ingestion of 250 mg PeakATP per day
Active Comparator: PeakATP 400
Oral supplement capsules containing 400 mg/day of PeakATP
Dietary Supplement: PeakATP 400
The nutritional intervention provides for oral ingestion of 400 mg PeakATP per day
Active Comparator: PeakATP 400 plus proprietary blend
Oral supplement capsules containing 400 mg/day of PeakATP plus a proprietary blend
Dietary Supplement: PeakATP 400 plus proprietary blend
The nutritional intervention provides for oral ingestion of 400 mg PeakATP per day plus a proprietary blend of additional nutrients

Detailed Description:

To date we have studied 10 subjects who have followed through with all 3 of the original interventions (Placebo, 250 mg PeakATP/d and 400 mg PeakATP/d). Currently we have received approval and are expanding the study with 5 additional subjects who will receive the Placebo, 400 mg PeakATP/d and the 400 mg PealATP/d plus proprietary blend interventions.
