What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Collagen and Vitamin C powder mix nutritional interventionDietary supplement

    20 g collagen + 50 mg vitamin C daily, 60 min prior to exercise

  • Maltodextrin placebo powderOther

    20 g maltodextrin placebo daily, 60 min prior to exercise

  • Maximum power training exerciseOther

    Explosive/power-based exercise training program 3 times/week at home consisting of drop jumps, box jumps, weighted jump squats loaded in a progressive manner weekly for 3 weeks. At baseline and at the end of each of the 3 weeks, measures of explosive performance are assessed in the lab (maximal isometric squat, counter-movement jump and squat jump)

What is being measured

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

  1. Maximal rate of force development (RFD) of isometric squat (MIS)

    Force (N) over time (msec) for the maximum slope of the first 20% of the movement

    Measured: % change from baseline to week 1, week 2 and week 3

  2. Counter-movement jump (CMJ) rate of force development (RFD)

    CMJ jump performance N/s/kg

    Measured: % change from baseline to week 1, week 2 and week 3

  3. Squat jump height rate of force development (RFD)

    Squat jump height performance RFD/kg

    Measured: % change from baseline to week 1, week 2 and week 3

Questions about this trial

What is this clinical trial studying?

A study testing Collagen and Vitamin C powder mix nutritional intervention and Maximum power training exercise in people with Collagen Synthesis and Rate of Force (RFD) Development, 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 4 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 18 Jun 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?

Maximal rate of force development (RFD) of isometric squat (MIS) (time frame: % change from baseline to week 1, week 2 and week 3). The study lists 3 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 Jun 2020.
