Resveratrol Supplementation on Exercise in Healthy Sedentary Adults

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01615445
Recruitment Status : Completed

Brief Summary:

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.

Drug Information available for: Resveratrol

Arm Intervention/treatment
Active Comparator: Resveratrol
Group A Participants will received resveratrol 500 mg twice daily for 1 week then 1000 mg twice daily for 3 weeks, according to tolerance. They will discontinue medication for 2 weeks. The will receive placebo for 4 weeks.
Drug: Resveratrol
Group A: resveratrol 1000 mg (500 mg twice) daily for 1 week then by tolerance and safety 2000 mg (1 000mg twice) daily for 3 weeks, followed by no medication for two weeks and then placebo for twice daily for 4 weeks.

Placebo Comparator: Placebo
Group B (n=6) Will receive placebo for 4 weeks, they will discontinue medication for two weeks. Then receive resveratrol for 4 weeks
Drug: placebo
Participants will receive placebo daily for 4 weeks, followed by no medication for two weeks and then resveratrol 1 000 mg(500 mg twice) daily for 1 week, then by tolerance and safety 2 000 mg (1 000 mg twice) daily for three weeks.

Primary Outcome Measures :
  1. 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.

  2. 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.

Secondary Outcome Measures :
  1. Number of participants with Adverse Events [ Time Frame: up to 10 weeks ]
