Resveratrol Supplementation on Exercise in Healthy Sedentary Adults

June 20, 2014 updated by: Ottawa Hospital Research Institute

A Pilot Randomized Controlled Clinical Trial of Resveratrol Supplementation on Exercise in Healthy Sedentary Adults

Previous animal studies have found that resveratrol supplementation significantly increased aerobic capacity. The investigators conducted a randomized placebo-controlled cross-over study to assess whether resveratrol could provide similar benefits in humans.

All participants were assigned to two 4-week treatment periods, with a 2 week washout in-between. During one period, volunteers in received resveratrol and during the other period, they received identical-appearing placebo.

The primary outcome of interest was change in exercise capacity, as measured by change in exercise duration on constant load exercise testing and change in aerobic capacity (peak VO2) on incremental exercise testing. Secondary outcomes were tolerability and side-effects associated with resveratrol.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from baseline in duration of constant load exercise
Time Frame: Phase I: Baseline and 4 weeks; Phase II (cross-over phase): 6 weeks and 10 weeks
The primary outcome would be the change in constant load exercise duration between baseline and follow-up visits, expressed as a percent change from the baseline constant load test. The average change from baseline will be compared between the experimental and control groups.
Phase I: Baseline and 4 weeks; Phase II (cross-over phase): 6 weeks and 10 weeks
Change from baseline in aerobic capacity(peak VO2)
Time Frame: Phase I: Baseline and 4 weeks; Phase II (cross-over phase): 6 weeks and 10 weeks
The aerobic capacity (peak VO2)is assessed by incremental exercise tests.
Phase I: Baseline and 4 weeks; Phase II (cross-over phase): 6 weeks and 10 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Number of participants with Adverse Events
Time Frame: up to 10 weeks
up to 10 weeks
