# Alpha memo: resveratrol exercise cross-context evidence signal
**One-sentence alpha:** Rodent studies suggest resveratrol can add to exercise-related molecular or oxidative endpoints, while a human trial in aged men suggests it may blunt some training gains, together marking a context-dependent boundary rather than a clean species translation.
**Receipt 1:** "The Impact of Resveratrol Supplementation on Inflammation Induced by Acute Exercise in Rats: Il6 Responses to Exercise" (2019) — an exercise-and-resveratrol protocol in male Wistar rats was aimed at evaluating inflammation-related factors; the supplied abstract is truncated before numerical results, so only the design is verifiable.
**Receipt 2:** "Resveratrol blunts the positive effects of exercise training in aged men; a double‐blind, randomized, placebo‐controlled training study" (2013) — 27 aged inactive men randomized to 250 mg resveratrol or placebo with high-intensity training three times weekly for 8 weeks; the title reports that resveratrol blunted positive training effects, while the supplied abstract is truncated before detailed endpoint numbers.
**Why this is surprising:** Receipt 1 leaves resveratrol-plus-exercise plausible at the level of a rodent inflammation protocol, and Receipt 2 then raises the possibility that the same combination may attenuate rather than augment human training adaptations, framing the shared anchor as context-sensitive.
**Caveats/falsifiers:**
- Receipt 1 is a rat model (male Wistar) with a 12-week exercise protocol plus an acute exercise bout at 20 weeks; Receipt 2 is aged men (~65 y) on 8 weeks of high-intensity training with 250 mg/day resveratrol — species, age, dose, route, duration, and baseline all differ, so the moderator hypothesis is tentative and confounded.
- Receipt 1's abstract is truncated and supplies no quantitative endpoint, and Receipt 2's abstract is truncated before detailed endpoint reporting, so both findings rest on partial text plus the Receipt 2 title claim.
- The pair is a heterogeneous cross-context signal (rodent inflammation model vs. aged-men training trial), not a direct overturning, and no clinical, dosing, or supplementation recommendation follows.
- Receipt 2 (2013) is older than Receipt 1 (2019) and is not framed as a replication; the later paper provides only mechanistic rodent context and does not resolve the human question.
- Decisive falsifier: a randomized human trial in aged adults testing resveratrol vs. placebo during structured training, with pre-specified vascular, inflammatory, and performance endpoints, would test whether the Receipt 2 attenuation generalizes beyond leg hemodynamics and microdialysate outcomes.
