What You Need to Know Before You Apply

What is the purpose of this trial?

This trial examines how a daily dose of resveratrol, a plant compound found in grapes, affects muscle function and soreness after exercise. Researchers aim to determine if resveratrol aids muscle recovery and reduces damage and stress indicators in individuals who engage in regular strength training. The trial targets healthy men who exercise regularly, specifically those who perform strength training with weights at least three times a week. Participants will take either resveratrol or a placebo for 17 days and report changes in muscle soreness and performance. As an unphased trial, this study provides participants the opportunity to contribute to groundbreaking research on muscle recovery.

Will I have to stop taking my current medications?

The trial requires participants to stop taking any performance-enhancing drugs and nutritional supplements known to improve physical performance for at least 28 days before starting the study. Regular use of prescription or over-the-counter medications that affect performance is also not allowed.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that resveratrol, a natural substance in red grapes, is usually safe for consumption. Studies have found that side effects rarely occur, and small doses are generally safe. For instance, taking 5-10 mg per day is typically fine, with no major negative effects reported at these levels.

Resveratrol is also known for reducing swelling and protecting cells from damage. However, the amount used in this study exceeds the usual daily recommendation. Participants should consider this and consult a healthcare provider if they have any concerns. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard methods for enhancing exercise performance, which typically involve endurance training, nutritional interventions, or performance-enhancing drugs, resveratrol stands out due to its natural origin and potential health benefits. Resveratrol is a compound found in the skin of red grapes and is believed to have antioxidant properties that may aid in exercise recovery and performance. Researchers are excited about resveratrol because it offers a novel approach by potentially enhancing mitochondrial function and reducing oxidative stress, which could improve endurance and recovery times in athletes. This makes resveratrol a promising alternative to current options that often come with side effects or require significant lifestyle changes.

What evidence suggests that resveratrol might be an effective treatment for exercise performance and recovery?

This trial will compare resveratrol supplementation with a placebo to evaluate its effects on exercise performance and recovery. Research has shown that resveratrol, a natural substance found in foods like red grapes, might improve exercise performance by increasing muscle strength and endurance. Some studies suggest it can boost power in athletes. However, strong evidence to confirm these benefits in people is still lacking. One study found that taking 500 mg of resveratrol daily, along with dieting and exercise, helped reduce liver fat. While these early results are promising, more research is needed to fully understand its impact on muscle recovery and performance. ^{2 3 6 7 8}

Published Research Related to This Trial

Synthetic cis-polymethoxystilbenes, derived from the biologically inactive cis-resveratrol, showed potent anti-cancer effects against metastatic B16 F10 melanoma cells, with an IC50 of less than 10 μM, indicating strong efficacy.

These compounds inhibited cell motility and proliferation more effectively than both cis- and trans-resveratrol, suggesting they could be promising candidates for chemotherapy in treating metastatic melanoma.

A study involving 25 healthy individuals found that after moderate consumption of red wine, trans-resveratrol was mostly present in the form of glucuronides in the bloodstream, rather than as free trans-resveratrol, indicating limited bioavailability of the compound itself.

The bioavailability of trans-resveratrol was consistent regardless of the type of meal consumed, suggesting that the health benefits attributed to red wine may be more related to the overall antioxidant content rather than just trans-resveratrol.

In a clinical trial involving 66 older adults with peripheral artery disease (PAD), resveratrol at a dose of 125 mg/day showed a slight improvement in 6-minute walk distance compared to placebo, but the results were not statistically significant (P=0.07).

The higher dose of 500 mg/day of resveratrol did not improve walking performance and was similar to the placebo group, indicating that resveratrol may not be an effective treatment for enhancing walking ability in older patients with PAD.

Trans-resveratrol is primarily metabolized into two main forms: trans-resveratrol-3-O-glucuronide and trans-resveratrol-3-sulfate, which were found abundantly in rat urine and mouse serum, indicating effective metabolism in the body.

The study found virtually no unconjugated resveratrol in urine or serum samples, suggesting that previous in vitro studies using only unconjugated resveratrol may not accurately reflect its metabolism and effects in living organisms.

Trans-resveratrol (t-RESV), found in grape skins and red wine, shows significant anti-inflammatory and anticarcinogenic properties in various experimental models, highlighting its potential as a therapeutic agent.

The cis isomer of resveratrol (c-RESV) is less studied and not commercially available, leading to a gap in understanding its pharmacological effects compared to the well-researched t-RESV.

A new method was developed to accurately measure resveratrol levels in animal and human samples, showing high specificity and recovery rates (96.8%) with a low detection limit of 50 ng/ml.

The study demonstrated that resveratrol can be effectively incorporated into blood cells and lipoproteins, suggesting its potential role in inhibiting lipoprotein oxidation and platelet activity.

Cis-resveratrol significantly reduces collagen-induced platelet aggregation in vitro, with a decrease of 43.5% at a concentration of 1 x 10(-5) M, indicating its potential as an anti-aggregating agent.

Trans-resveratrol also shows anti-aggregating effects but is slightly less effective than cis-resveratrol, suggesting that both isomers should be considered when evaluating resveratrol's overall activity in biological systems.

Trans-resveratrol at a dosage of 2000 mg twice daily was found to be well tolerated in a study of eight healthy subjects, although diarrhea was a common side effect in six participants.

The study revealed that taking trans-resveratrol with a standard breakfast maximizes its absorption, while a high-fat meal significantly reduces its plasma concentration, indicating the importance of meal composition on its pharmacokinetics.

This study analyzed the content of trans- and cis-resveratrol in 18 commercial Serbian wines, revealing that trans-resveratrol was present in all but one sample, with concentrations ranging from 0.11 to 1.69 mg/L.

Cis-resveratrol was found in 12 out of the 18 wines, with levels between 0.12 and 1.49 mg/L, indicating that Serbian wines contain significant amounts of these beneficial compounds, which are associated with various health benefits.

Red wines contain significantly higher levels of beneficial compounds like resveratrol and piceid, averaging 4.37 mg/liter, compared to only 0.68 mg/liter in white wines, suggesting a stronger protective effect against cardiovascular disease from red wine consumption.

The study analyzed 42 wines from various regions in Japan, confirming that specific grape varieties, such as Pinot noir, Merlot, and Zweigeltrebe, have particularly high resveratrol content, which may contribute to their health benefits.
